+
+-- autoconf 2.56 or later
+-- automake 1.7 or later
+-- libtool 1.4 or later
+
+-- NASM (if building x86 or x86-64 SIMD extensions)
+   * 0.98, or 2.01 or later is required for a 32-bit build
+   * NASM 2.00 or later is required for a 64-bit build
+   * NASM 2.07 or later is required for a 64-bit build on OS X.  This can be
+     obtained from MacPorts (http://www.macports.org/).
+
+   The binary RPMs released by the NASM project do not work on older Linux
+   systems, such as Red Hat Enterprise Linux 4.  On such systems, you can
+   easily build and install NASM from a source RPM by downloading one of the
+   SRPMs from
+
+   http://www.nasm.us/pub/nasm/releasebuilds
+
+   and executing the following as root:
+
+     ARCH=`uname -m`
+     rpmbuild --rebuild nasm-{version}.src.rpm
+     rpm -Uvh /usr/src/redhat/RPMS/$ARCH/nasm-{version}.$ARCH.rpm
+
+   NOTE: the NASM build will fail if texinfo is not installed.
+
+-- GCC v4.1 or later recommended for best performance
+
+-- If building the TurboJPEG/OSS Java wrapper, JDK or OpenJDK 1.5 or later is
+   required.  Some systems, such as OS X 10.4, Solaris 10 and later, and Red
+   Hat Enterprise Linux 5 and later, have this pre-installed.  On OS X 10.5 and
+   later, it will be necessary to install the Java Developer Package, which can
+   be downloaded from http://connect.apple.com.  For systems that do not have a
+   JDK installed, you can obtain the Oracle Java Development Kit from
+   http://www.java.com.
+
+
+==================
+Out-of-Tree Builds
+==================
+
+Binary objects, libraries, and executables are generated in the same directory
+from which configure was executed (the "binary directory"), and this directory
+need not necessarily be the same as the libjpeg-turbo source directory.  You
+can create multiple independent binary directories, in which different versions
+of libjpeg-turbo can be built from the same source tree using different
+compilers or settings.  In the sections below, {build_directory} refers to the
+binary directory, whereas {source_directory} refers to the libjpeg-turbo source
+directory.  For in-tree builds, these directories are the same.
+
+
+======================
+Building libjpeg-turbo
+======================
+
+The following procedure will build libjpeg-turbo on Linux, FreeBSD, 32-bit
+OS X, Cygwin, and Solaris/x86 systems (on Solaris, this generates a 32-bit
+library.  See below for 64-bit build instructions.)
+
+  cd {source_directory}
+  autoreconf -fiv
+  cd {build_directory}
+  sh {source_directory}/configure [additional configure flags]
+  make
+
+NOTE: Running autoreconf in the source directory is only necessary if building
+libjpeg-turbo from the SVN repository.
+
+This will generate the following files under .libs/
+
+  libjpeg.a
+      Static link library for libjpeg-turbo
+
+  libjpeg.so.{version} (Linux, Solaris)
+  libjpeg.{version}.dylib (OS X)
+  cygjpeg-{version}.dll (Cygwin)
+      Shared library for libjpeg-turbo
+
+  libjpeg.so (Linux, Solaris)
+  libjpeg.dylib (OS X)
+  libjpeg.dll.a (Cygwin)
+      Development stub for libjpeg-turbo shared library
+
+  libturbojpeg.a
+      Static link library for TurboJPEG/OSS
+
+  libturbojpeg.so (Linux, Solaris)
+  libturbojpeg.dylib (OS X)
+      Shared library and development stub for TurboJPEG/OSS
+
+  cygturbojpeg.dll (Cygwin)
+      Shared library for TurboJPEG/OSS
+
+  libturbojpeg.dll.a (Cygwin)
+      Development stub for TurboJPEG/OSS shared library
+
+{version} is 62.0.0, 7.0.0, or 8.0.2, depending on whether libjpeg v6b
+(default), v7, or v8 emulation is enabled.  If using Cygwin, {version} is
+62, 7, or 8.
+
+
+libjpeg v7 or v8 API/ABI Emulation
+----------------------------------
+
+Add --with-jpeg7 to the configure command line to build a version of
+libjpeg-turbo that is API/ABI-compatible with libjpeg v7.  Add --with-jpeg8 to
+the configure command to build a version of libjpeg-turbo that is
+API/ABI-compatible with libjpeg v8.  See README-turbo.txt for more information
+on libjpeg v7 and v8 emulation.
+
+
+Arithmetic Coding Support
+-------------------------
+
+Since the patent on arithmetic coding has expired, this functionality has been
+included in this release of libjpeg-turbo.  libjpeg-turbo's implementation is
+based on the implementation in libjpeg v8, but it works when emulating libjpeg
+v7 or v6b as well.  The default is to enable both arithmetic encoding and
+decoding, but those who have philosophical objections to arithmetic coding can
+add --without-arith-enc or --without-arith-dec to the configure command line to
+disable encoding or decoding (respectively.)
+
+
+TurboJPEG/OSS Java Wrapper
+--------------------------
+Add --with-java to the configure command line to incorporate an optional Java
+Native Interface wrapper into the TurboJPEG/OSS dynamic library and build the
+Java front-end classes to support it.  This allows the TurboJPEG/OSS dynamic
+library to be used directly from Java applications.  See java/README for more
+details.
+
+You can set the JAVAC, JAR, and JAVA configure variables to specify
+alternate commands for javac, jar, and java (respectively.)  You can also
+set the JAVACFLAGS configure variable to specify arguments that should be
+passed to the Java compiler when building the front-end classes, and JNI_CFLAGS
+to specify arguments that should be passed to the C compiler when building the
+JNI wrapper.  Run 'configure --help' for more details.
+
+
+========================
+Installing libjpeg-turbo
+========================
+
+If you intend to install these libraries and the associated header files, then
+replace 'make' in the instructions above with
+
+  make install prefix={base dir} libdir={library directory}
+
+For example,
+
+  make install prefix=/usr/local libdir=/usr/local/lib64
+
+will install the header files in /usr/local/include and the library files in
+/usr/local/lib64.  If 'prefix' and 'libdir' are not specified, then the default
+is to install the header files in /opt/libjpeg-turbo/include and the library
+files in /opt/libjpeg-turbo/lib.
+
+NOTE: You can specify a prefix of /usr and a libdir of, for instance,
+/usr/lib64 to overwrite the system's version of libjpeg.  If you do this,
+however, then be sure to BACK UP YOUR SYSTEM'S INSTALLATION OF LIBJPEG before
+overwriting it.  It is recommended that you instead install libjpeg-turbo into
+a non-system directory and manipulate the LD_LIBRARY_PATH or create sym links
+to force applications to use libjpeg-turbo instead of libjpeg.  See
+README-turbo.txt for more information.

+    LDFLAGS='-B/usr/lib32'
+
+to the configure command line.  NASM 2.07 or later from FreeBSD ports must be
+installed.
+
+
+Oracle Solaris Studio
+---------------------
+
+Add
+
+  CC=cc
+
+to the configure command line.  libjpeg-turbo will automatically be built with
+the maximum optimization level (-xO5) unless you override CFLAGS.
+
+To build a 64-bit version of libjpeg-turbo using Oracle Solaris Studio, add
+
+  --host x86_64-pc-solaris CC=cc CFLAGS='-xO5 -m64' LDFLAGS=-m64
+
+to the configure command line.
+
+
+MinGW Build on Cygwin
+---------------------
+
+Use CMake (see recipes below)
+
+
+===========
+ARM Support
+===========
+
+This release of libjpeg-turbo can use ARM NEON SIMD instructions to accelerate
+JPEG compression/decompression by approximately 2-4x on ARMv7 and later
+platforms.  If libjpeg-turbo is configured on an ARM Linux platform, then the
+build system will automatically include the NEON SIMD routines, if they are
+supported.
+
+
+Building libjpeg-turbo for iOS
+------------------------------
+
+iOS platforms, such as the iPhone and iPad, also use ARM processors, some of
+which support NEON instructions.  Additional steps are required to build
+libjpeg-turbo for these platforms.  The steps below assume iOS SDK v4.3.  If
+you are using a different SDK version, then you will need to modify the
+examples accordingly.
+
+Additional build requirements:
+
+  gas-preprocessor.pl (https://github.com/yuvi/gas-preprocessor) should be
+  installed in your PATH.
+
+Set the following shell variables for simplicity:
+
+  IOS_PLATFORMDIR="/Developer/Platforms/iPhoneOS.platform"
+  IOS_SYSROOT="$IOS_PLATFORMDIR/Developer/SDKs/iPhoneOS4.3.sdk"
+  IOS_GCC="$IOS_PLATFORMDIR/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2"
+
+  ARM v6 only (up to and including iPhone 3G):
+  IOS_CFLAGS="-march=armv6 -mcpu=arm1176jzf-s -mfpu=vfp"
+
+  ARM v7 only (iPhone 3GS and newer, iPad):
+  IOS_CFLAGS="-march=armv7 -mcpu=cortex-a8 -mtune=cortex-a8 -mfpu=neon"
+
+Follow the procedure under "Building libjpeg-turbo" above, adding
+
+  --host arm-apple-darwin10 --enable-static --disable-shared \
+    CC="$IOS_GCC" LD="$IOS_GCC" \
+    CFLAGS="-mfloat-abi=softfp -isysroot $IOS_SYSROOT -O3 $IOS_CFLAGS" \
+    LDFLAGS="-mfloat-abi=softfp -isysroot $IOS_SYSROOT $IOS_CFLAGS"
+
+to the configure command line.
+
+Once built, lipo can be used to combine the ARM v6 and v7 variants into a
+universal library.

+-- CMake (http://www.cmake.org) v2.6 or later
+
+-- Microsoft Visual C++ 2005 or later
+
+   If you don't already have Visual C++, then the easiest way to get it is by
+   installing the Windows SDK:
+
+   http://msdn.microsoft.com/en-us/windows/bb980924.aspx
+
+   The Windows SDK includes both 32-bit and 64-bit Visual C++ compilers and
+   everything necessary to build libjpeg-turbo.
+
+   * For 32-bit builds, you can also use Microsoft Visual C++ Express
+     Edition.  Visual C++ Express Edition is a free download.
+   * If you intend to build libjpeg-turbo from the command line, then add the
+     appropriate compiler and SDK directories to the INCLUDE, LIB, and PATH
+     environment variables.  This is generally accomplished by executing
+     vcvars32.bat or vcvars64.bat and SetEnv.cmd.  vcvars32.bat and
+     vcvars64.bat are part of Visual C++ and are located in the same directory
+     as the compiler.  SetEnv.cmd is part of the Windows SDK.  You can pass
+     optional arguments to SetEnv.cmd to specify a 32-bit or 64-bit build
+     environment.

+==================
+Out-of-Tree Builds
+==================
+
+Binary objects, libraries, and executables are generated in the same directory
+from which cmake was executed (the "binary directory"), and this directory need
+not necessarily be the same as the libjpeg-turbo source directory.  You can
+create multiple independent binary directories, in which different versions of
+libjpeg-turbo can be built from the same source tree using different compilers
+or settings.  In the sections below, {build_directory} refers to the binary
+directory, whereas {source_directory} refers to the libjpeg-turbo source
+directory.  For in-tree builds, these directories are the same.
+
+
+======================
+Building libjpeg-turbo
+======================
+
+
+Visual C++ (Command Line)
+-------------------------
+
+  cd {build_directory}
+  cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release {source_directory}
+  nmake
+
+This will build either a 32-bit or a 64-bit version of libjpeg-turbo, depending
+on which version of cl.exe is in the PATH.
+
+The following files will be generated under {build_directory}:
+
+  jpeg-static.lib
+      Static link library for libjpeg-turbo
+  sharedlib/jpeg{version}.dll
+      DLL for libjpeg-turbo
+  sharedlib/jpeg.lib
+      Import library for libjpeg-turbo DLL
+  turbojpeg-static.lib
+      Static link library for TurboJPEG/OSS
+  turbojpeg.dll
+      DLL for TurboJPEG/OSS
+  turbojpeg.lib
+      Import library for TurboJPEG/OSS DLL
+
+{version} is 62, 7, or 8, depending on whether libjpeg v6b (default), v7, or
+v8 emulation is enabled.
+
+
+Visual C++ (IDE)
+----------------
+
+Choose the appropriate CMake generator option for your version of Visual Studio
+(run "cmake" with no arguments for a list of available generators.)  For
+instance:
+
+  cd {build_directory}
+  cmake -G "Visual Studio 9 2008" {source_directory}
+
+You can then open ALL_BUILD.vcproj in Visual Studio and build one of the
+configurations in that project ("Debug", "Release", etc.) to generate a full
+build of libjpeg-turbo.
+
+This will generate the following files under {build_directory}:
+
+  {configuration}/jpeg-static.lib
+      Static link library for libjpeg-turbo
+  sharedlib/{configuration}/jpeg{version}.dll
+      DLL for libjpeg-turbo
+  sharedlib/{configuration}/jpeg.lib
+      Import library for libjpeg-turbo DLL
+  {configuration}/turbojpeg-static.lib
+      Static link library for TurboJPEG/OSS
+  {configuration}/turbojpeg.dll
+      DLL for TurboJPEG/OSS
+  {configuration}/turbojpeg.lib
+      Import library for TurboJPEG/OSS DLL
+
+{configuration} is Debug, Release, RelWithDebInfo, or MinSizeRel, depending on
+the configuration you built in the IDE, and {version} is 62, 7, or 8,
+depending on whether libjpeg v6b (default), v7, or v8 emulation is enabled.
+
+
+MinGW
+-----
+
+  cd {build_directory}
+  cmake -G "MSYS Makefiles" {source_directory}
+  make
+
+This will generate the following files under {build_directory}
+
+  libjpeg.a
+      Static link library for libjpeg-turbo
+  sharedlib/libjpeg-{version}.dll
+      DLL for libjpeg-turbo
+  sharedlib/libjpeg.dll.a
+      Import library for libjpeg-turbo DLL
+  libturbojpeg.a
+      Static link library for TurboJPEG/OSS
+  libturbojpeg.dll
+      DLL for TurboJPEG/OSS
+  libturbojpeg.dll.a
+      Import library for TurboJPEG/OSS DLL
+
+{version} is 62, 7, or 8, depending on whether libjpeg v6b (default), v7, or
+v8 emulation is enabled.
+
+
+Debug Build
+-----------
+
+Add "-DCMAKE_BUILD_TYPE=Debug" to the cmake command line.  Or, if building with
+NMake, remove "-DCMAKE_BUILD_TYPE=Release" (Debug builds are the default with
+NMake.)
+
+
+libjpeg v7 or v8 API/ABI Emulation
+-----------------------------------
+
+Add "-DWITH_JPEG7=1" to the cmake command line to build a version of
+libjpeg-turbo that is API/ABI-compatible with libjpeg v7.  Add "-DWITH_JPEG8=1"
+to the cmake command to build a version of libjpeg-turbo that is
+API/ABI-compatible with libjpeg v8.  See README-turbo.txt for more information
+on libjpeg v7 and v8 emulation.
+
+
+Arithmetic Coding Support
+-------------------------
+
+Since the patent on arithmetic coding has expired, this functionality has been
+included in this release of libjpeg-turbo.  libjpeg-turbo's implementation is
+based on the implementation in libjpeg v8, but it works when emulating libjpeg
+v7 or v6b as well.  The default is to enable both arithmetic encoding and
+decoding, but those who have philosophical objections to arithmetic coding can
+add "-DWITH_ARITH_ENC=0" or "-DWITH_ARITH_DEC=0" to the cmake command line to
+disable encoding or decoding (respectively.)
+
+
+TurboJPEG/OSS Java Wrapper
+--------------------------
+Add "-DWITH_JAVA=1" to the cmake command line to incorporate an optional Java
+Native Interface wrapper into the TurboJPEG/OSS dynamic library and build the
+Java front-end classes to support it.  This allows the TurboJPEG/OSS dynamic
+library to be used directly from Java applications.  See java/README for more
+details.
+
+If you are using CMake 2.8, you can set the Java_JAVAC_EXECUTABLE,
+Java_JAVA_EXECUTABLE, and Java_JAR_EXECUTABLE CMake variables to specify
+alternate commands or locations for javac, jar, and java (respectively.)  If
+you are using CMake 2.6, set JAVA_COMPILE, JAVA_RUNTIME, and JAVA_ARCHIVE
+instead.  You can also set the JAVACFLAGS CMake variable to specify arguments
+that should be passed to the Java compiler when building the front-end classes.
+
+
+========================
+Installing libjpeg-turbo
+========================
+
+You can use the build system to install libjpeg-turbo into a directory of your
+choosing (as opposed to creating an installer.)  To do this, add:
+
+  -DCMAKE_INSTALL_PREFIX={install_directory}
+
+to the cmake command line.
+
+For example,
+
+  cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release \
+    -DCMAKE_INSTALL_PREFIX=c:\libjpeg-turbo {source_directory}
+  nmake install
+
+will install the header files in c:\libjpeg-turbo\include, the library files
+in c:\libjpeg-turbo\lib, the DLL's in c:\libjpeg-turbo\bin, and the
+documentation in c:\libjpeg-turbo\doc.

+    -DCMAKE_RANLIB=/usr/bin/x86_64-w64-mingw32-ranlib {source_directory}
+  make
+
+This produces a 64-bit build of libjpeg-turbo that does not depend on

+*******************************************************************************
+**     Creating Release Packages
+*******************************************************************************
+
+The following commands can be used to create various types of release packages:
+
+
+Unix
+----
+
+make rpm
+
+  Create Red Hat-style binary RPM package.  Requires RPM v4 or later.
+
+make srpm
+
+  This runs 'make dist' to create a pristine source tarball, then creates a
+  Red Hat-style source RPM package from the tarball.  Requires RPM v4 or later.
+
+make deb
+
+  Create Debian-style binary package.  Requires dpkg.
+
+make dmg
+
+  Create Macintosh package/disk image.  This requires the PackageMaker
+  application, which must be installed in /Developer/Applications/Utilities.
+
+make udmg [BUILDDIR32={32-bit build directory}]
+
+  On 64-bit OS X systems, this creates a Macintosh package and disk image that
+  contains universal i386/x86-64 binaries.  You should first configure a 32-bit
+  out-of-tree build of libjpeg-turbo, then configure a 64-bit out-of-tree
+  build, then run 'make udmg' from the 64-bit build directory.  The build
+  system will look for the 32-bit build under {source_directory}/osxx86 by
+  default, but you can override this by setting the BUILDDIR32 variable on the
+  make command line as shown above.
+
+make iosdmg [BUILDDIR32={32-bit build directory}] \
+  [BUILDDIRARMV6={ARM v6 build directory}] \
+  [BUILDDIRARMV7={ARM v7 build directory}] \
+
+  On OS X systems, this creates a Macintosh package and disk image in which the
+  libjpeg-turbo static libraries contain ARM architectures necessary to build
+  iOS applications.  If building on an x86-64 system, the binaries will also
+  contain the i386 architecture, as with 'make udmg' above.  You should first
+  configure ARM v6 and ARM v7 out-of-tree builds of libjpeg-turbo (see
+  "Building libjpeg-turbo for iOS" above.)  If you are building an x86-64
+  version of libjpeg-turbo, you should configure a 32-bit out-of-tree build as
+  well.  Next, build libjpeg-turbo as you would normally, using an out-of-tree
+  build.  When it is built, run 'make iosdmg' from the build directory.  The
+  build system will look for the ARM v6 build under {source_directory}/iosarmv6
+  by default, the ARM v7 build under {source_directory}/iosarmv7 by default,
+  and (if applicable) the 32-bit build under {source_directory}/osxx86 by
+  default, but you can override this by setting the BUILDDIR32, BUILDDIRARMV6,
+  and/or BUILDDIRARMV7 variables on the make command line as shown above.
+
+make sunpkg
+
+  Build a Solaris package.  This requires pkgmk, pkgtrans, and bzip2.
+
+make csunpkg [BUILDDIR32={32-bit build directory}]
+
+  On 64-bit Solaris systems, this creates a combined package that contains
+  both 32-bit and 64-bit libraries.  You should first configure a 32-bit
+  out-of-tree build of libjpeg-turbo, then configure a 64-bit out-of-tree
+  build, then run 'make csunpkg' from the 64-bit build directory.  The build
+  system will look for the 32-bit build under {source_directory}/solx86 by
+  default, but you can override this by setting the BUILDDIR32 variable on the
+  make command line as shown above.
+
+make cygwinpkg
+
+  Build a Cygwin binary package.
+
+
+Windows
+-------
+
+If using NMake:
+
+  cd {build_directory}
+  nmake installer
+
+If using MinGW:
+
+  cd {build_directory}
+  make installer
+
+If using the Visual Studio IDE, build the "installer" project.
+
+The installer package (libjpeg-turbo[-gcc][64].exe) will be located under
+{build_directory}.  If building using the Visual Studio IDE, then the installer
+package will be located in a subdirectory with the same name as the
+configuration you built (such as {build_directory}\Debug\ or
+{build_directory}\Release\).
+
+Building a Windows installer requires the Nullsoft Install System
+(http://nsis.sourceforge.net/.)  makensis.exe should be in your PATH.
+
+
+*******************************************************************************
+**     Regression testing
+*******************************************************************************
+
+The most common way to test libjpeg-turbo is by invoking 'make test' on
+Unix/Linux platforms or 'ctest' on Windows platforms, once the build has
+completed.  This runs a series of tests to ensure that mathematical
+compatibility has been maintained between libjpeg-turbo and libjpeg v6b.  This
+also invokes the TurboJPEG unit tests, which ensure that the colorspace
+extensions, YUV encoding, decompression scaling, and other features of the
+TurboJPEG C and Java APIs are working properly (and, by extension, that the
+equivalent features of the underlying libjpeg API are also working.)
+
+Invoking 'make testclean' or 'nmake testclean' (if using NMake) or building
+the 'testclean' target (if using the Visual Studio IDE) will clean up the
+output images generated by 'make test'.
+
+On Unix/Linux platforms, more extensive tests of the TurboJPEG/OSS C and Java
+wrappers can be run by invoking 'make tjtest'.  These extended TurboJPEG tests
+essentially iterate through all of the available features of the TurboJPEG APIs
+that are not covered by the TurboJPEG unit tests (this includes the lossless
+transform options) and compare the images generated by each feature to images
+generated using the equivalent feature in the libjpeg API.  The extended
+TurboJPEG tests are meant to test for regressions in the TurboJPEG wrappers,
+not in the underlying libjpeg-turbo library.

CHANGELOG

-CHANGELOG for Independent JPEG Group's JPEG software
-
-
-Version 4A 18-Feb-93
---------------------
-
-Substantial speedup for grayscale output from color JPEG file (suppress
-processing of chrominance components).  Lesser speedups in Huffman decoding
-and in compression quantization.
-
-Can switch stdin/stdout to binary mode with either fdopen() or setmode();
-this allows use of one-file command line style on a wider range of systems.
-Also added -outfile switch so that makefile test scripts don't have to depend
-on the command line style.
-
-New makefile.icc for Code Builder; makefile.sas is updated for SAS C 6.x.
-
-Hook added to allow surrounding application to read and write COM (comment)
-blocks.
-
-Bugfixes (DOS only): jmemdos.c code for accessing expanded memory only worked
-if struct fields are packed on byte boundaries.  This is not true by default
-for Microsoft C.  Furthermore, Microsoft C needs an _fheapmin() call to clean
-up the far heap correctly.
-
-
-Version 4  10-Dec-92
---------------------
-
-Revised user interface: switches now use names instead of single letters.
-(Old switch letters are acceptable abbreviations of new switch names, EXCEPT
-for djpeg's old -g, -D, -1 switches.)  cjpeg has several new switches.
-
-Provision for smoothing the input image added to cjpeg.  This helps a lot with
-converting dithered GIFs to JPEG.
-
-Decoder upsampling now uses interpolation instead of pixel replication; this
-improves rendering of sharp colored edges.
-
-The decompressor will now try to continue after detecting an error in the
-compressed data, instead of just aborting.  If the input file has restart
-markers, full synchronization will usually be regained at the next undamaged
-restart marker.  (But you're still out of luck if any of the header markers
-are corrupt.)
-
-Substantial improvements in speed; DCT accuracy improved too.
-
-Numerous minor changes to improve portability.  egetopt.c, which was by far
-the worst portability problem, is gone altogether.
-
-A few bugfixes, sigh (mostly affecting DOS implementations only).
-Bugfix: on DOS machines, cjpeg -o would fail on grayscale input files.
-Bugfix: one-pass quantization to more than 64 color levels would fail on
-16-bit-int machines.  This could only happen with quantized grayscale output.
-
-A couple of changes affect code that calls the JPEG subroutine library:
-
-1. The parameter struct tag names are now capitalized (Compress_info_struct,
-Compress_methods_struct, Decompress_info_struct, Decompress_methods_struct,
-and External_methods_struct).  This makes it easier to live with brain-damaged
-compilers with short identifier lengths.  (All identifiers used in the JPEG
-code are now unique within the first 16 characters.)
-
-2. If you are not calling jselerror(), you need to initialize three new fields
-in the emethods structure, typically as follows:
-    e_methods.num_warnings = 0; /* no warnings emitted yet */
-    e_methods.first_warning_level = 0; /* display first corrupt-data warning */
-    e_methods.more_warning_level = 3; /* but suppress additional ones */
-These fields control handling of corrupt-data warnings.
-
-
-Version 3  17-Mar-92
---------------------
-
-Memory manager is finally capable of swapping to temp files.  There are
-separate versions of jmemsys.c for no temp files (same behavior as older
-versions), simple temp files with or without tmpfile(), and a DOS-specific
-version (including special code for EMS and XMS).  This is probably much more
-system-dependent than any of the older code; some bugs may surface here.
-
-Hooks added for user interface to install progress monitoring routine
-(percent-done bar, etc).  See comments with dummy progress_monitor
-routines in jcdeflts.c, jddeflts.c.
-
-Two-pass color quantization (finally!).  This is now the default method when
-quantizing; say '-1' to djpeg for quick-and-ugly 1-pass method.  There is
-a test file for checking 2-pass quantization and GIF output.
-
-Fixed bug in jcopy_block_row that broke cjpeg -o option and djpeg -b option
-on MSDOS machines.
-
-Miscellaneous small speedups; notably, DCT computation rearranged so that
-GCC "inline" feature is no longer needed for good code quality.
-
-File config.c renamed ckconfig.c to avoid name conflict with /etc/config
-on Unix systems.
-
-Added example.c to document usage of JPEG subroutines better.
-
-Memory manager now knows how to release all storage during error exit ---
-avoids memory leak when using JPEG as subroutines.  This implies a couple
-small changes to the subroutine interface: the old free_defaults subroutines
-are no longer needed, but if you have a replacement error_exit method then it
-must call the new free_all method.  Also, jselvirtmem renamed to jselmemmgr.
-
-Code for reading Targa files with 32-bit pixels was incorrect.
-
-Colorspace conversion slightly faster and more accurate; because of
-this, old "test" files will no longer match bit-for-bit.
-
-
-Version 2  13-Dec-91
---------------------
-
-Documentation improved a little --- there are man pages now.
-Installation instructions moved from README to a separate file SETUP.
-
-New program config.c is provided to help you get the configuration options
-right.  This should make installation a lot more foolproof.
-
-Sense of djpeg -D switch reversed: dithering is now ON by default.
-
-RLE image file support added (thanks to Mike Lijewski).
-
-Targa image file support added (thanks to Lee Crocker).
-
-PPM input now accepts all PPM and PGM files.
-
-Bug fix: on machines where 'int' is 16 bits, high-Q-setting JPEG files
-were not decoded correctly.
-
-Numerous changes to improve portability.  There should be few or no compiler
-warnings now.
-
-Makefiles cleaned up; defaults now appropriate for production use rather than
-debugging.
-
-Subroutine interface cleaned up.  If you wrote code based on version 1's
-jcmain/jdmain, you'll need to change it, but it should get a little shorter
-and simpler.
-
-
-Version 1   7-Oct-91
---------------------
-
-Initial public release.

+1.2.1
+=====
+
+[1] Creating or decoding a JPEG file that uses the RGB colorspace should now
+properly work when the input or output colorspace is one of the libjpeg-turbo
+colorspace extensions.
+
+[2] When libjpeg-turbo was built without SIMD support and merged (non-fancy)
+upsampling was used along with an alpha-enabled colorspace during
+decompression, the unused byte of the decompressed pixels was not being set to
+0xFF.  This has been fixed.  TJUnitTest has also been extended to test for the
+correct behavior of the colorspace extensions when merged upsampling is used.
+
+[3] Fixed a bug whereby the libjpeg-turbo SSE2 SIMD code would not preserve the
+upper 64 bits of xmm6 and xmm7 on Win64 platforms, which violated the Win64
+calling conventions.
+
+[4] Fixed a regression caused by 1.2.0[6] whereby decompressing corrupt JPEG
+images (specifically, images in which the component count was erroneously set
+to a large value) would cause libjpeg-turbo to segfault.
+
+[5] Worked around a severe performance issue with "Bobcat" (AMD Embedded APU)
+processors.  The MASKMOVDQU instruction, which was used by the libjpeg-turbo
+SSE2 SIMD code, is apparently implemented in microcode on AMD processors, and
+it is painfully slow on Bobcat processors in particular.  Eliminating the use
+of this instruction improved performance by an order of magnitude on Bobcat
+processors and by a small amount (typically 5%) on AMD desktop processors.
+
+[6] Added SIMD acceleration for performing 4:2:2 upsampling on NEON-capable ARM
+platforms.  This speeds up the decompression of 4:2:2 JPEGs by 20-25% on such
+platforms.
+
+[7] Fixed a regression caused by 1.2.0[2] whereby, on Linux/x86 platforms
+running the 32-bit SSE2 SIMD code in libjpeg-turbo, decompressing a 4:2:0 or
+4:2:2 JPEG image into a 32-bit (RGBX, BGRX, etc.) buffer without using fancy
+upsampling would produce several incorrect columns of pixels at the right-hand
+side of the output image if each row in the output image was not evenly
+divisible by 16 bytes.
+
+[8] Fixed an issue whereby attempting to build the SIMD extensions with Xcode
+4.3 on OS X platforms would cause NASM to return numerous errors of the form
+"'%define' expects a macro identifier".
+
+[9] Added flags to the TurboJPEG API that allow the caller to force the use of
+either the fast or the accurate DCT/IDCT algorithms in the underlying codec.
+
+
+1.2.0
+=====
+
+[1] Fixed build issue with YASM on Unix systems (the libjpeg-turbo build system
+was not adding the current directory to the assembler include path, so YASM
+was not able to find jsimdcfg.inc.)
+
+[2] Fixed out-of-bounds read in SSE2 SIMD code that occurred when decompressing
+a JPEG image to a bitmap buffer whose size was not a multiple of 16 bytes.
+This was more of an annoyance than an actual bug, since it did not cause any
+actual run-time problems, but the issue showed up when running libjpeg-turbo in
+valgrind.  See http://crbug.com/72399 for more information.
+
+[3] Added a compile-time macro (LIBJPEG_TURBO_VERSION) that can be used to
+check the version of libjpeg-turbo against which an application was compiled.
+
+[4] Added new RGBA/BGRA/ABGR/ARGB colorspace extension constants (libjpeg API)
+and pixel formats (TurboJPEG API), which allow applications to specify that,
+when decompressing to a 4-component RGB buffer, the unused byte should be set
+to 0xFF so that it can be interpreted as an opaque alpha channel.
+
+[5] Fixed regression issue whereby DevIL failed to build against libjpeg-turbo
+because libjpeg-turbo's distributed version of jconfig.h contained an INLINE
+macro, which conflicted with a similar macro in DevIL.  This macro is used only
+internally when building libjpeg-turbo, so it was moved into config.h.
+
+[6] libjpeg-turbo will now correctly decompress erroneous CMYK/YCCK JPEGs whose
+K component is assigned a component ID of 1 instead of 4.  Although these files
+are in violation of the spec, other JPEG implementations handle them
+correctly.
+
+[7] Added ARM v6 and ARM v7 architectures to libjpeg.a and libturbojpeg.a in
+the official OS X distribution package, so that those libraries can be used to
+build both OS X and iOS applications.
+
+
+1.1.90 (1.2 beta1)
+==================
+
+[1] Added a Java wrapper for the TurboJPEG API.  See java/README for more
+details.
+
+[2] The TurboJPEG API can now be used to scale down images during
+decompression.
+
+[3] Added SIMD routines for RGB-to-grayscale color conversion, which
+significantly improves the performance of grayscale JPEG compression from an
+RGB source image.
+
+[4] Improved the performance of the C color conversion routines, which are used
+on platforms for which SIMD acceleration is not available.
+
+[5] Added a function to the TurboJPEG API that performs lossless transforms.
+This function is implemented using the same back end as jpegtran, but it
+performs transcoding entirely in memory and allows multiple transforms and/or
+crop operations to be batched together, so the source coefficients only need to
+be read once.  This is useful when generating image tiles from a single source
+JPEG.
+
+[6] Added tests for the new TurboJPEG scaled decompression and lossless
+transform features to tjbench (the TurboJPEG benchmark, formerly called
+"jpgtest".)
+
+[7] Added support for 4:4:0 (transposed 4:2:2) subsampling in TurboJPEG, which
+was necessary in order for it to read 4:2:2 JPEG files that had been losslessly
+transposed or rotated 90 degrees.
+
+[8] All legacy VirtualGL code has been re-factored, and this has allowed
+libjpeg-turbo, in its entirety, to be re-licensed under a BSD-style license.
+
+[9] libjpeg-turbo can now be built with YASM.
+
+[10] Added SIMD acceleration for ARM Linux and iOS platforms that support
+NEON instructions.
+
+[11] Refactored the TurboJPEG C API and documented it using Doxygen.  The
+TurboJPEG 1.2 API uses pixel formats to define the size and component order of
+the uncompressed source/destination images, and it includes a more efficient
+version of TJBUFSIZE() that computes a worst-case JPEG size based on the level
+of chrominance subsampling.  The refactored implementation of TurboJPEG/OSS
+now uses the libjpeg memory source and destination managers, which allows the
+TurboJPEG compressor to grow the JPEG buffer as necessary.
+
+[12] Eliminated errors in the output of jpegtran on Windows that occurred when
+the application was invoked using I/O redirection
+(jpegtran <input.jpg >output.jpg).
+
+[13] The inclusion of libjpeg v7 and v8 emulation as well as arithmetic coding
+support in libjpeg-turbo v1.1.0 introduced several new error constants in
+jerror.h, and these were mistakenly enabled for all emulation modes, causing
+the error enum in libjpeg-turbo to sometimes have different values than the
+same enum in libjpeg.  This represents an ABI incompatibility, and it caused
+problems with rare applications that took specific action based on a particular
+error value.  The fix was to include the new error constants conditionally
+based on whether libjpeg v7 or v8 emulation was enabled.
+
+[14] Fixed an issue whereby Windows applications that used libjpeg-turbo would
+fail to compile if the Windows system headers were included before jpeglib.h.
+This issue was caused by a conflict in the definition of the INT32 type.
+
+[15] Fixed 32-bit supplementary package for amd64 Debian systems, which was
+broken by enhancements to the packaging system in 1.1.
+
+[16] When decompressing a JPEG image using an output colorspace of
+JCS_EXT_RGBX, JCS_EXT_BGRX, JCS_EXT_XBGR, or JCS_EXT_XRGB, libjpeg-turbo will
+now set the unused byte to 0xFF, which allows applications to interpret that
+byte as an alpha channel (0xFF = opaque).
+
+
+1.1.1
+=====
+
+[1] Fixed a 1-pixel error in row 0, column 21 of the luminance plane generated
+by tjEncodeYUV().
+
+[2] libjpeg-turbo's accelerated Huffman decoder previously ignored unexpected
+markers found in the middle of the JPEG data stream during decompression.  It
+will now hand off decoding of a particular block to the unaccelerated Huffman
+decoder if an unexpected marker is found, so that the unaccelerated Huffman
+decoder can generate an appropriate warning.
+
+[3] Older versions of MinGW64 prefixed symbol names with underscores by
+default, which differed from the behavior of 64-bit Visual C++.  MinGW64 1.0
+has adopted the behavior of 64-bit Visual C++ as the default, so to accommodate
+this, the libjpeg-turbo SIMD function names are no longer prefixed with an
+underscore when building with MinGW64.  This means that, when building
+libjpeg-turbo with older versions of MinGW64, you will now have to add
+-fno-leading-underscore to the CFLAGS.
+
+[4] Fixed a regression bug in the NSIS script that caused the Windows installer
+build to fail when using the Visual Studio IDE.
+
+[5] Fixed a bug in jpeg_read_coefficients() whereby it would not initialize
+cinfo->image_width and cinfo->image_height if libjpeg v7 or v8 emulation was
+enabled.  This specifically caused the jpegoptim program to fail if it was
+linked against a version of libjpeg-turbo that was built with libjpeg v7 or v8
+emulation.
+
+[6] Eliminated excessive I/O overhead that occurred when reading BMP files in
+cjpeg.
+
+[7] Eliminated errors in the output of cjpeg on Windows that occurred when the
+application was invoked using I/O redirection (cjpeg <inputfile >output.jpg).
+
+
+1.1.0
+=====
+
+[1] The algorithm used by the SIMD quantization function cannot produce correct
+results when the JPEG quality is >= 98 and the fast integer forward DCT is
+used.  Thus, the non-SIMD quantization function is now used for those cases,
+and libjpeg-turbo should now produce identical output to libjpeg v6b in all
+cases.
+
+[2] Despite the above, the fast integer forward DCT still degrades somewhat for
+JPEG qualities greater than 95, so TurboJPEG/OSS will now automatically use the
+slow integer forward DCT when generating JPEG images of quality 96 or greater.
+This reduces compression performance by as much as 15% for these high-quality
+images but is necessary to ensure that the images are perceptually lossless.
+It also ensures that the library can avoid the performance pitfall created by
+[1].
+
+[3] Ported jpgtest.cxx to pure C to avoid the need for a C++ compiler.
+
+[4] Fixed visual artifacts in grayscale JPEG compression caused by a typo in
+the RGB-to-luminance lookup tables.
+
+[5] The Windows distribution packages now include the libjpeg run-time programs
+(cjpeg, etc.)
+
+[6] All packages now include jpgtest.
+
+[7] The TurboJPEG dynamic library now uses versioned symbols.
+
+[8] Added two new TurboJPEG API functions, tjEncodeYUV() and
+tjDecompressToYUV(), to replace the somewhat hackish TJ_YUV flag.
+
+
+1.0.90 (1.1 beta1)
+==================
+
+[1] Added emulation of the libjpeg v7 and v8 APIs and ABIs.  See
+README-turbo.txt for more details.  This feature was sponsored by CamTrace SAS.
+
+[2] Created a new CMake-based build system for the Visual C++ and MinGW builds.
+
+[3] Grayscale bitmaps can now be compressed from/decompressed to using the
+TurboJPEG API.
+
+[4] jpgtest can now be used to test decompression performance with existing
+JPEG images.
+
+[5] If the default install prefix (/opt/libjpeg-turbo) is used, then
+'make install' now creates /opt/libjpeg-turbo/lib32 and
+/opt/libjpeg-turbo/lib64 sym links to duplicate the behavior of the binary
+packages.
+
+[6] All symbols in the libjpeg-turbo dynamic library are now versioned, even
+when the library is built with libjpeg v6b emulation.
+
+[7] Added arithmetic encoding and decoding support (can be disabled with
+configure or CMake options)
+
+[8] Added a TJ_YUV flag to the TurboJPEG API, which causes both the compressor
+and decompressor to output planar YUV images.
+
+[9] Added an extended version of tjDecompressHeader() to the TurboJPEG API,
+which allows the caller to determine the type of subsampling used in a JPEG
+image.
+
+[10] Added further protections against invalid Huffman codes.
+
+
+1.0.1
+=====
+
+[1] The Huffman decoder will now handle erroneous Huffman codes (for instance,
+from a corrupt JPEG image.)  Previously, these would cause libjpeg-turbo to
+crash under certain circumstances.
+
+[2] Fixed typo in SIMD dispatch routines that was causing 4:2:2 upsampling to
+be used instead of 4:2:0 when decompressing JPEG images using SSE2 code.
+
+[3] configure script will now automatically determine whether the
+INCOMPLETE_TYPES_BROKEN macro should be defined.
+
+
+1.0.0
+=====
+
+[1] 2983700: Further FreeBSD build tweaks (no longer necessary to specify
+--host when configuring on a 64-bit system)
+
+[2] Created sym. links in the Unix/Linux packages so that the TurboJPEG
+include file can always be found in /opt/libjpeg-turbo/include, the 32-bit
+static libraries can always be found in /opt/libjpeg-turbo/lib32, and the
+64-bit static libraries can always be found in /opt/libjpeg-turbo/lib64.
+
+[3] The Unix/Linux distribution packages now include the libjpeg run-time
+programs (cjpeg, etc.) and man pages.
+
+[4] Created a 32-bit supplementary package for amd64 Debian systems, which
+contains just the 32-bit libjpeg-turbo libraries.
+
+[5] Moved the libraries from */lib32 to */lib in the i386 Debian package.
+
+[6] Include distribution package for Cygwin
+
+[7] No longer necessary to specify --without-simd on non-x86 architectures, and
+unit tests now work on those architectures.

-WHAT'S HERE
-===========
+OVERVIEW
+========
 
-This distribution contains C software to implement JPEG image compression and
-decompression.  JPEG (pronounced "jay-peg") is a standardized compression
-method for full-color and gray-scale images.  JPEG is intended for compressing
-"real-world" scenes; cartoons and other non-realistic images are not its
-strong suit.  JPEG is lossy, meaning that the output image is not necessarily
-identical to the input image.  Hence you must not use JPEG if you have to have
-identical output bits.  However, on typical images of real-world scenes, very
-good compression levels can be obtained with no visible change, and amazingly
-high compression levels are possible if you can tolerate a low-quality image.
-For more details, see the references, or just experiment with various
-compression settings.
+This package contains C software to implement JPEG image encoding, decoding,
+and transcoding.  JPEG (pronounced "jay-peg") is a standardized compression
+method for full-color and gray-scale images.  JPEG's strong suit is compressing
+photographic images or other types of images that have smooth color and
+brightness transitions between neighboring pixels.  Images with sharp lines or
+other abrupt features may not compress well with JPEG, and a higher JPEG
+quality may have to be used to avoid visible compression artifacts with such
+images.
 
-The software implements JPEG baseline and extended-sequential compression
-processes.  Provision is made for supporting all variants of these processes,
-although some uncommon parameter settings aren't implemented yet.  For legal
-reasons, we are not distributing code for the arithmetic-coding process; see
-LEGAL ISSUES.  At present we have made no provision for supporting the
-progressive, hierarchical, or lossless processes defined in the standard.
+JPEG is lossy, meaning that the output pixels are not necessarily identical to
+the input pixels.  However, on photographic content and other "smooth" images,
+very good compression ratios can be obtained with no visible compression
+artifacts, and extremely high compression ratios are possible if you are
+willing to sacrifice image quality (by reducing the "quality" setting in the
+compressor.)
+
+This software implements JPEG baseline, extended-sequential, and progressive
+compression processes.  Provision is made for supporting all variants of these
+processes, although some uncommon parameter settings aren't implemented yet.
+We have made no provision for supporting the hierarchical or lossless
+processes defined in the standard.
+
+We provide a set of library routines for reading and writing JPEG image files,
+plus two sample applications "cjpeg" and "djpeg", which use the library to
+perform conversion between JPEG and some other popular image file formats.
+The library is intended to be reused in other applications.
 
 In order to support file conversion and viewing software, we have included
 considerable functionality beyond the bare JPEG coding/decoding capability;
 for example, the color quantization modules are not strictly part of JPEG
 decoding, but they are essential for output to colormapped file formats or
-colormapped displays.  These extra functions can be compiled out if not
-required for a particular application.
+colormapped displays.  These extra functions can be compiled out of the
+library if not required for a particular application.
+
+We have also included "jpegtran", a utility for lossless transcoding between
+different JPEG processes, and "rdjpgcom" and "wrjpgcom", two simple
+applications for inserting and extracting textual comments in JFIF files.
 
 The emphasis in designing this software has been on achieving portability and
 flexibility, while also making it fast enough to be useful.  In particular,
 the software is not intended to be read as a tutorial on JPEG.  (See the
-REFERENCES section for introductory material.)  While we hope that the entire
-package will someday be industrial-strength code, much remains to be done in
-performance tuning and in improving the capabilities of individual modules.
+REFERENCES section for introductory material.)  Rather, it is intended to
+be reliable, portable, industrial-strength code.  We do not claim to have
+achieved that goal in every aspect of the software, but we strive for it.
 
-
-This software can be used on several levels:
-
-* As canned software for JPEG compression and decompression.  Just edit the
-  Makefile and configuration files as needed (see file SETUP), compile and go.
-  Members of the Independent JPEG Group will improve the out-of-the-box
-  functionality and speed as time goes on.
-
-* As the basis for other JPEG programs.  For example, you could incorporate
-  the decompressor into a general image viewing package by replacing the
-  output module with write-to-screen functions.  For an implementation on
-  specific hardware, you might want to replace some of the inner loops with
-  assembly code.  For a non-command-line-driven system, you might want a
-  different user interface.  (Members of the group will be producing Macintosh
-  and Amiga versions with more appropriate user interfaces, for example.)
-
-* As a toolkit for experimentation with JPEG and JPEG-like algorithms.  Most
-  of the individual decisions you might want to mess with are packaged up into
-  separate modules.  For example, the details of color-space conversion and
-  subsampling techniques are each localized in one compressor and one
-  decompressor module.  You'd probably also want to extend the user interface
-  to give you more detailed control over the JPEG compression parameters.
-
-In particular, we welcome the use of this software as a component of commercial
-products; no royalty is required.

-ARCHIVE LOCATIONS
-=================
-
-[Version 4A is a beta-test release and will not be publicly archived.
-The following paragraphs refer to the most recent official release.]
-
-The "official" archive site for this software is ftp.uu.net (Internet
-address 137.39.1.9 or 192.48.96.9).  The most recent released version can
-always be found there in directory graphics/jpeg.  This particular version
-will be archived as jpegsrc.v4.tar.Z.  If you are on the Internet, you can
-retrieve files from UUNET by anonymous FTP.  If you don't have FTP access,
-UUNET's archives are also available via UUCP; contact postmaster@uunet.uu.net
-for information on retrieving files that way.
-
-Numerous Internet sites maintain copies of the UUNET files; in particular,
-you can probably find a copy at any site that archives comp.sources.misc
-submissions.  However, only ftp.uu.net is guaranteed to have the latest
-official version.
-
-You can also obtain this software from CompuServe, in the GRAPHSUPPORT forum
-(GO PICS), library 15; this version will be file jpsrc4.zip.  Again,
-CompuServe is not guaranteed to have the very latest version.
-
-The JPEG FAQ (Frequently Asked Questions) article is a useful source of
-general information about JPEG.  It is updated constantly and therefore
-is not included in this distribution.  The FAQ is posted every two weeks
-to Usenet newsgroups comp.graphics, news.answers, and other groups.  You
-can always obtain the latest version from the news.answers archive at
-rtfm.mit.edu (18.172.1.27).  By FTP, fetch /pub/usenet/news.answers/jpeg-faq.
-If you don't have FTP, send e-mail to mail-server@rtfm.mit.edu with body
-"send usenet/news.answers/jpeg-faq".
-
-
-SUPPORTING SOFTWARE
-===================
-
-You will probably want Jef Poskanzer's PBMPLUS image software, which provides
-many useful operations on PPM-format image files.  In particular, it can
-convert PPM images to and from a wide range of other formats.  You can FTP
-this free software from export.lcs.mit.edu (contrib/pbmplus*.tar.Z) or
-ftp.ee.lbl.gov (pbmplus*.tar.Z).  Unfortunately PBMPLUS is not nearly as
-portable as the JPEG software is; you are likely to have difficulty making it
-work on any non-Unix machine.
-
-If you are using X Windows you might want to use the xv or xloadimage viewers
-to save yourself the trouble of converting PPM to some other format.  Both of
-these can be found in the contrib directory at export.lcs.mit.edu.  Actually,
-xv version 2.00 and up incorporates our software and thus can read and write
-JPEG files directly.  (NOTE: since xv internally reduces all images to 8
-bits/pixel, a JPEG file written by xv will not be very high quality; and xv
-cannot fully exploit a 24-bit display.  These problems are expected to go away
-in the next xv release, planned for early 1993.  In the meantime, use
-xloadimage for 24-bit displays.)
-
-For DOS machines, Lee Crocker's free Piclab program is a useful companion to
-the JPEG software.  The latest version, currently 1.91, is available by FTP
-from SIMTEL20 and its various mirror sites, file <msdos.graphics>piclb191.zip.
-CompuServe also has it, in the same library as the JPEG software.

-
-SOFTWARE THAT'S NO HELP AT ALL
-==============================
-
-Handmade Software's shareware PC program GIF2JPG produces files that are
-totally incompatible with our programs.  They use a proprietary format that is
-an amalgam of GIF and JPEG representations.  However, you can force GIF2JPG
-to produce compatible files with its -j switch, and their decompression
-program JPG2GIF can read our files (at least ones produced with our default
-option settings).
-
-Some commercial JPEG implementations are also incompatible as of this writing,
-especially programs released before summer 1991.  The root of the problem is
-that the ISO JPEG committee failed to specify a concrete file format.  Some
-vendors "filled in the blanks" on their own, creating proprietary formats that
-no one else could read.  (For example, none of the early commercial JPEG
-implementations for the Macintosh were able to exchange compressed files.)
-
-The file format we have adopted is called JFIF (see REFERENCES).  This format
-has been agreed to by a number of major commercial JPEG vendors, and we expect
-that it will become the de facto standard.  JFIF is a minimal representation;
-work is also going forward to incorporate JPEG compression into the TIFF 6.0
-standard, for use in "high end" applications that need to record a lot of
-additional data about an image.  We intend to support TIFF 6.0 in the future.
-We hope that these two formats will be sufficient and that other, incompatible
-JPEG file formats will not proliferate.
-
-Indeed, part of the reason for developing and releasing this free software is
-to help force rapid convergence to de facto standards for JPEG file formats.
-SUPPORT STANDARD, NON-PROPRIETARY FORMATS: demand JFIF or TIFF 6.0!
-
-
-USING JPEG AS A SUBROUTINE IN A LARGER PROGRAM
-==============================================
-
-You can readily incorporate the JPEG compression and decompression routines in
-a larger program.  The file example.c provides a skeleton of the interface
-routines you'll need for this purpose.  Essentially, you replace jcmain.c (for
-compression) and/or jdmain.c (for decompression) with your own code.  Note
-that the fewer JPEG options you allow the user to twiddle, the less code you
-need; all the default options are set up automatically.  (Alternately, if you
-know a lot about JPEG or have a special application, you may want to twiddle
-the default options even more extensively than jcmain/jdmain do.)
-
-Most likely, you will want the uncompressed image to come from memory (for
-compression) or go to memory or the screen (for decompression).  For this
-purpose you must provide image reading or writing routines that match the
-interface used by the image file I/O modules (jrdXXX or jwrXXX); again,
-example.c shows a skeleton of what is required.  In this situation, you
-won't need any of the non-JPEG image file I/O modules used by cjpeg and djpeg.
-
-By default, any error detected inside the JPEG routines will cause a message
-to be printed on stderr, followed by exit().  You can override this behavior
-by supplying your own message-printing and/or error-exit routines; again,
-example.c shows how.
-
-We recommend you create libjpeg.a as shown in the Makefile, then link that
-with your surrounding program.  (If your linker is at all reasonable, only the
-code you actually need will get loaded.)  Include the files jconfig.h and
-jpegdata.h in C files that need to call the JPEG routines.
-
-CAUTION: some people have tried to compile JPEG and their surrounding code
-with different compilers, e.g., cc for JPEG and c++ or gcc for the rest.  This
-is a Real Bad Move and you will deserve what happens to you if you try it.
-(Hint: the parameter structures can get laid out differently with no warning.)
-
-Read our "architecture" file for more info.  If it seems to you that the
-software structure doesn't accommodate what you want to do, please contact
-the authors.
-
-Beginning with version 3, we will endeavor to hold the interface described by
-example.c constant, so that you can plug in updated versions of the JPEG code
-just by recompiling.  However, we can't guarantee this, especially if you
-choose to twiddle any JPEG options not listed in example.c.  Check the
-CHANGELOG when installing any new version, and compare example.c against the
-prior version.  Recompile your calling software (don't just relink), as we may
-add or subtract fields in the parameter structures.

 TO DO

-The next major release will probably be a significant rewrite to allow use of
-this code in conjunction with Sam Leffler's free TIFF library (assuming the
-bugs in the TIFF 6.0 specification get resolved).
-
-Many of the modules need fleshing out to provide more complete
-implementations, or to provide faster paths for common cases.
-Speeding things up is still high on our priority list.
-
-We'd appreciate it if people would compile and check out the code on as wide a
-variety of systems as possible, and report any portability problems
-encountered (with solutions, if possible).  Checks of file compatibility with
-other JPEG implementations would also be of interest.  Finally, we would
-appreciate code profiles showing where the most time is spent, especially on

+**     Background
+*******************************************************************************
+
+libjpeg-turbo is a derivative of libjpeg that uses SIMD instructions (MMX,
+SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86,
+x86-64, and ARM systems.  On such systems, libjpeg-turbo is generally 2-4x as
+fast as the unmodified version of libjpeg, all else being equal.
+
+libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but
+the TigerVNC and VirtualGL projects made numerous enhancements to the codec in
+2009, including improved support for Mac OS X, 64-bit support, support for
+32-bit and big-endian pixel formats (RGBX, XBGR, etc.), accelerated Huffman
+encoding/decoding, and various bug fixes.  The goal was to produce a fully
+open-source codec that could replace the partially closed-source TurboJPEG/IPP
+codec used by VirtualGL and TurboVNC.  libjpeg-turbo generally achieves 80-120%
+of the performance of TurboJPEG/IPP.  It is faster in some areas but slower in
+others.
+
+In early 2010, libjpeg-turbo spun off into its own independent project, with
+the goal of making high-speed JPEG compression/decompression technology
+available to a broader range of users and developers.

+*******************************************************************************
+**     Using libjpeg-turbo
+*******************************************************************************
+
+libjpeg-turbo includes two APIs that can be used to compress and decompress
+JPEG images:
+
+  TurboJPEG API:  This API provides an easy-to-use interface for compressing
+  and decompressing JPEG images in memory.  It also provides some functionality
+  that would not be straightforward to achieve using the underlying libjpeg
+  API, such as generating planar YUV images and performing multiple
+  simultaneous lossless transforms on an image.  The Java interface for
+  libjpeg-turbo is written on top of the TurboJPEG API.
+
+  libjpeg API:  This is the de facto industry-standard API for compressing and
+  decompressing JPEG images.  It is more difficult to use than the TurboJPEG
+  API but also more powerful.  libjpeg-turbo is both API/ABI-compatible and
+  mathematically compatible with libjpeg v6b.  It can also optionally be
+  configured to be API/ABI-compatible with libjpeg v7 and v8 (see below.)
+
+
+=============================
+Replacing libjpeg at Run Time
+=============================
+
+If a Unix application is dynamically linked with libjpeg, then you can replace
+libjpeg with libjpeg-turbo at run time by manipulating LD_LIBRARY_PATH.
+For instance:
+
+  [Using libjpeg]
+  > time cjpeg <vgl_5674_0098.ppm >vgl_5674_0098.jpg
+  real  0m0.392s
+  user  0m0.074s
+  sys   0m0.020s
+
+  [Using libjpeg-turbo]
+  > export LD_LIBRARY_PATH=/opt/libjpeg-turbo/{lib}:$LD_LIBRARY_PATH
+  > time cjpeg <vgl_5674_0098.ppm >vgl_5674_0098.jpg
+  real  0m0.109s
+  user  0m0.029s
+  sys   0m0.010s
+
+NOTE: {lib} can be lib, lib32, lib64, or lib/64, depending on the O/S and
+architecture.
+
+System administrators can also replace the libjpeg sym links in /usr/{lib} with
+links to the libjpeg-turbo dynamic library located in /opt/libjpeg-turbo/{lib}.
+This will effectively accelerate every application that uses the libjpeg
+dynamic library on the system.
+
+The libjpeg-turbo SDK for Visual C++ installs the libjpeg-turbo DLL
+(jpeg62.dll, jpeg7.dll, or jpeg8.dll, depending on whether it was built with
+libjpeg v6b, v7, or v8 emulation) into c:\libjpeg-turbo[64]\bin, and the PATH
+environment variable can be modified such that this directory is searched
+before any others that might contain a libjpeg DLL.  However, if a libjpeg
+DLL exists in an application's install directory, then Windows will load this
+DLL first whenever the application is launched.  Thus, if an application ships
+with jpeg62.dll, jpeg7.dll, or jpeg8.dll, then back up the application's
+version of this DLL and copy c:\libjpeg-turbo[64]\bin\jpeg*.dll into the
+application's install directory to accelerate it.
+
+The version of the libjpeg-turbo DLL distributed in the libjpeg-turbo SDK for
+Visual C++ requires the Visual C++ 2008 C run-time DLL (msvcr90.dll).
+msvcr90.dll ships with more recent versions of Windows, but users of older
+Windows releases can obtain it from the Visual C++ 2008 Redistributable
+Package, which is available as a free download from Microsoft's web site.
+
+NOTE:  Features of libjpeg that require passing a C run-time structure, such
+as a file handle, from an application to libjpeg will probably not work with
+the version of the libjpeg-turbo DLL distributed in the libjpeg-turbo SDK for
+Visual C++, unless the application is also built to use the Visual C++ 2008 C
+run-time DLL.  In particular, this affects jpeg_stdio_dest() and
+jpeg_stdio_src().
+
+Mac applications typically embed their own copies of the libjpeg dylib inside
+the (hidden) application bundle, so it is not possible to globally replace
+libjpeg on OS X systems.  If an application uses a shared library version of
+libjpeg, then it may be possible to replace the application's version of it.
+This would generally involve copying libjpeg.*.dylib from libjpeg-turbo into
+the appropriate place in the application bundle and using install_name_tool to
+repoint the dylib to the new directory.  This requires an advanced knowledge of
+OS X and would not survive an upgrade or a re-install of the application.
+Thus, it is not recommended for most users.
+
+=======================
+Replacing TurboJPEG/IPP
+=======================
+
+libjpeg-turbo is a drop-in replacement for the TurboJPEG/IPP SDK used by
+VirtualGL 2.1.x and TurboVNC 0.6 (and prior.)  libjpeg-turbo contains a wrapper
+library (TurboJPEG/OSS) that emulates the TurboJPEG API using libjpeg-turbo
+instead of the closed-source Intel Performance Primitives.  You can replace the
+TurboJPEG/IPP package on Linux systems with the libjpeg-turbo package in order
+to make existing releases of VirtualGL 2.1.x and TurboVNC 0.x use the new codec
+at run time.  Note that the 64-bit libjpeg-turbo packages contain only 64-bit
+binaries, whereas the TurboJPEG/IPP 64-bit packages contained both 64-bit and
+32-bit binaries.  Thus, to replace a TurboJPEG/IPP 64-bit package, install
+both the 64-bit and 32-bit versions of libjpeg-turbo.
+
+You can also build the VirtualGL 2.1.x and TurboVNC 0.6 source code with
+the libjpeg-turbo SDK instead of TurboJPEG/IPP.  It should work identically.
+libjpeg-turbo also includes static library versions of TurboJPEG/OSS, which
+are used to build VirtualGL 2.2 and TurboVNC 1.0 and later.
+
+========================================
+Using libjpeg-turbo in Your Own Programs
+========================================
+
+For the most part, libjpeg-turbo should work identically to libjpeg, so in
+most cases, an application can be built against libjpeg and then run against
+libjpeg-turbo.  On Unix systems (including Cygwin), you can build against
+libjpeg-turbo instead of libjpeg by setting
+
+  CPATH=/opt/libjpeg-turbo/include
+  and
+  LIBRARY_PATH=/opt/libjpeg-turbo/{lib}
+
+({lib} = lib32 or lib64, depending on whether you are building a 32-bit or a
+64-bit application.)
+
+If using MinGW, then set
+
+  CPATH=/c/libjpeg-turbo-gcc[64]/include
+  and
+  LIBRARY_PATH=/c/libjpeg-turbo-gcc[64]/lib
+
+Building against libjpeg-turbo is useful, for instance, if you want to build an
+application that leverages the libjpeg-turbo colorspace extensions (see below.)
+On Linux and Solaris systems, you would still need to manipulate
+LD_LIBRARY_PATH or create appropriate sym links to use libjpeg-turbo at run
+time.  On such systems, you can pass -R /opt/libjpeg-turbo/{lib} to the linker
+to force the use of libjpeg-turbo at run time rather than libjpeg (also useful
+if you want to leverage the colorspace extensions), or you can link against the
+libjpeg-turbo static library.
+
+To force a Linux, Solaris, or MinGW application to link against the static
+version of libjpeg-turbo, you can use the following linker options:
+
+  -Wl,-Bstatic -ljpeg -Wl,-Bdynamic
+
+On OS X, simply add /opt/libjpeg-turbo/lib/libjpeg.a to the linker command
+line (this also works on Linux and Solaris.)
+
+To build Visual C++ applications using libjpeg-turbo, add
+c:\libjpeg-turbo[64]\include to the system or user INCLUDE environment
+variable and c:\libjpeg-turbo[64]\lib to the system or user LIB environment
+variable, and then link against either jpeg.lib (to use the DLL version of
+libjpeg-turbo) or jpeg-static.lib (to use the static version of libjpeg-turbo.)
+
+=====================
+Colorspace Extensions
+=====================
+
+libjpeg-turbo includes extensions that allow JPEG images to be compressed
+directly from (and decompressed directly to) buffers that use BGR, BGRX,
+RGBX, XBGR, and XRGB pixel ordering.  This is implemented with ten new
+colorspace constants:
+
+  JCS_EXT_RGB   /* red/green/blue */
+  JCS_EXT_RGBX  /* red/green/blue/x */
+  JCS_EXT_BGR   /* blue/green/red */
+  JCS_EXT_BGRX  /* blue/green/red/x */
+  JCS_EXT_XBGR  /* x/blue/green/red */
+  JCS_EXT_XRGB  /* x/red/green/blue */
+  JCS_EXT_RGBA  /* red/green/blue/alpha */
+  JCS_EXT_BGRA  /* blue/green/red/alpha */
+  JCS_EXT_ABGR  /* alpha/blue/green/red */
+  JCS_EXT_ARGB  /* alpha/red/green/blue */
+
+Setting cinfo.in_color_space (compression) or cinfo.out_color_space
+(decompression) to one of these values will cause libjpeg-turbo to read the
+red, green, and blue values from (or write them to) the appropriate position in
+the pixel when compressing from/decompressing to an RGB buffer.
+
+Your application can check for the existence of these extensions at compile
+time with:
+
+  #ifdef JCS_EXTENSIONS
+
+At run time, attempting to use these extensions with a version of libjpeg
+that doesn't support them will result in a "Bogus input colorspace" error.
+
+When using the RGBX, BGRX, XBGR, and XRGB colorspaces during decompression, the
+X byte is undefined, and in order to ensure the best performance, libjpeg-turbo
+can set that byte to whatever value it wishes.  If an application expects the X
+byte to be used as an alpha channel, then it should specify JCS_EXT_RGBA,
+JCS_EXT_BGRA, JCS_EXT_ABGR, or JCS_EXT_ARGB.  When these colorspace constants
+are used, the X byte is guaranteed to be 0xFF, which is interpreted as opaque.
+
+Your application can check for the existence of the alpha channel colorspace
+extensions at compile time with:
+
+  #ifdef JCS_ALPHA_EXTENSIONS
+
+jcstest.c, located in the libjpeg-turbo source tree, demonstrates how to check
+for the existence of the colorspace extensions at compile time and run time.
+
+=================================
+libjpeg v7 and v8 API/ABI support
+=================================
+
+With libjpeg v7 and v8, new features were added that necessitated extending the
+compression and decompression structures.  Unfortunately, due to the exposed
+nature of those structures, extending them also necessitated breaking backward
+ABI compatibility with previous libjpeg releases.  Thus, programs that are
+built to use libjpeg v7 or v8 did not work with libjpeg-turbo, since it is
+based on the libjpeg v6b code base.  Although libjpeg v7 and v8 are still not
+as widely used as v6b, enough programs (including a few Linux distros) have
+made the switch that it was desirable to provide support for the libjpeg v7/v8
+API/ABI in libjpeg-turbo.  Although libjpeg-turbo can now be configured as a
+drop-in replacement for libjpeg v7 or v8, it should be noted that not all of
+the features in libjpeg v7 and v8 are supported (see below.)
+
+By passing an argument of --with-jpeg7 or --with-jpeg8 to configure, or an
+argument of -DWITH_JPEG7=1 or -DWITH_JPEG8=1 to cmake, you can build a version
+of libjpeg-turbo that emulates the libjpeg v7 or v8 API/ABI, so that programs
+that are built against libjpeg v7 or v8 can be run with libjpeg-turbo.  The
+following section describes which libjpeg v7+ features are supported and which
+aren't.
+
+libjpeg v7 and v8 Features:
+---------------------------
+
+Fully supported:
+
+-- cjpeg: Separate quality settings for luminance and chrominance
+   Note that the libpjeg v7+ API was extended to accommodate this feature only
+   for convenience purposes.  It has always been possible to implement this
+   feature with libjpeg v6b (see rdswitch.c for an example.)
+
+-- cjpeg: 32-bit BMP support
+
+-- jpegtran: lossless cropping
+
+-- jpegtran: -perfect option
+
+-- rdjpgcom: -raw option
+
+-- rdjpgcom: locale awareness
+
+
+Fully supported when using libjpeg v7/v8 emulation:
+
+-- libjpeg: In-memory source and destination managers
+
+
+Not supported:
+
+-- libjpeg: DCT scaling in compressor
+   cinfo.scale_num and cinfo.scale_denom are silently ignored.
+   There is no technical reason why DCT scaling cannot be supported, but
+   without the SmartScale extension (see below), it would only be able to
+   down-scale using ratios of 1/2, 8/15, 4/7, 8/13, 2/3, 8/11, 4/5, and 8/9,
+   which is of limited usefulness.
+
+-- libjpeg: SmartScale
+   cinfo.block_size is silently ignored.
+   SmartScale is an extension to the JPEG format that allows for DCT block
+   sizes other than 8x8.  It would be difficult to support this feature while
+   retaining backward compatibility with libjpeg v6b.
+
+-- libjpeg: IDCT scaling extensions in decompressor
+   libjpeg-turbo still supports IDCT scaling with scaling factors of 1/2, 1/4,
+   and 1/8 (same as libjpeg v6b.)
+
+-- libjpeg: Fancy downsampling in compressor
+   cinfo.do_fancy_downsampling is silently ignored.
+   This requires the DCT scaling feature, which is not supported.
+
+-- jpegtran: Scaling
+   This requires both the DCT scaling and SmartScale features, which are not
+   supported.
+
+-- Lossless RGB JPEG files
+   This requires the SmartScale feature, which is not supported.
+
+
+*******************************************************************************
+**     Performance pitfalls
+*******************************************************************************
+
+===============
+Restart Markers
+===============
+
+The optimized Huffman decoder in libjpeg-turbo does not handle restart markers
+in a way that makes the rest of the libjpeg infrastructure happy, so it is
+necessary to use the slow Huffman decoder when decompressing a JPEG image that
+has restart markers.  This can cause the decompression performance to drop by
+as much as 20%, but the performance will still be much greater than that of
+libjpeg.  Many consumer packages, such as PhotoShop, use restart markers when
+generating JPEG images, so images generated by those programs will experience
+this issue.
+
+===============================================
+Fast Integer Forward DCT at High Quality Levels
+===============================================
+
+The algorithm used by the SIMD-accelerated quantization function cannot produce
+correct results whenever the fast integer forward DCT is used along with a JPEG
+quality of 98-100.  Thus, libjpeg-turbo must use the non-SIMD quantization
+function in those cases.  This causes performance to drop by as much as 40%.
+It is therefore strongly advised that you use the slow integer forward DCT
+whenever encoding images with a JPEG quality of 98 or higher.

-SETUP instructions for the Independent JPEG Group's JPEG software
-=================================================================
-
-This file explains how to configure and compile the JPEG software.  We have
-tried to make this software extremely portable and flexible, so that it can be
-adapted to almost any environment.  The downside of this decision is that the
-installation process is not very automatic; you will need at least a little
-familiarity with C programming and program build procedures for your system.
-
-This file contains general instructions, then sections of specific hints for
-certain systems.  You may save yourself considerable time if you scan the
-whole file before starting to do anything.
-
-Before installing the software you must unpack the distributed source code.
-Since you are reading this file, you have probably already succeeded in this
-task.  However, there is one potential trap if you are on a non-Unix system:
-you may need to convert these files to the local standard text file format
-(for example, if you are on MS-DOS you probably have to convert LF end-of-line
-to CR/LF).  If so, apply the conversion to all the files EXCEPT those whose
-names begin with "test".  The test files contain binary data; if you change
-them in any way then the self-test will give bad results.
-
-
-STEP 1: PREPARE A MAKEFILE
-==========================
-
-First, select a makefile and copy it to "Makefile" (or whatever your version
-of make uses as the default makefile name; for example, "makefile.mak" for
-old versions of Borland C).  We include several standard makefiles in the
-distribution:
-
-	makefile.ansi:	for Unix systems with ANSI-compatible C compilers.
-	makefile.unix:	for Unix systems with non-ANSI C compilers.
-	makefile.mc5:	for Microsoft C 5.x under MS-DOS.
-	makefile.mc6:	for Microsoft C 6.x and up under MS-DOS.
-	makefile.bcc:	for Borland C (Turbo C) under MS-DOS.
-	makefile.icc:	for Intel's Code Builder C under MS-DOS.
-	makefile.manx:	for Manx Aztec C on Amigas.
-	makefile.sas:	for SAS C on Amigas.
-	makcjpeg.st:	project file for Atari ST/STE/TT Pure C or Turbo C.
-	makdjpeg.st:	project file for Atari ST/STE/TT Pure C or Turbo C.
-	makljpeg.st:	project file for Atari ST/STE/TT Pure C or Turbo C.
-	makefile.mms:	for VAX/VMS systems with MMS.
-	makefile.vms:	for VAX/VMS systems without MMS.
-
-If you don't see a makefile for your system, we recommend starting from either
-makefile.ansi or makefile.unix, depending on whether your compiler accepts
-ANSI C or not.  Actually you should start with makefile.ansi whenever your
-compiler supports ANSI-style function definitions; you don't need full ANSI
-compatibility.  The difference between the two makefiles is that makefile.unix
-preprocesses the source code to convert function definitions to old-style C.
-(Our thanks to Peter Deutsch of Aladdin Enterprises for the ansi2knr program.)
-
-If you don't know whether your compiler supports ANSI-style function
-definitions, then take a look at ckconfig.c.  It is a test program that will
-help you figure out this fact, as well as some other facts you'll need in
-later steps.  You must compile and execute ckconfig.c by hand; the makefiles
-don't provide any support for this.  ckconfig.c may not compile the first try
-(in fact, the whole idea is for it to fail if anything is going to).  If you
-get compile errors, fix them by editing ckconfig.c according to the directions
-given in ckconfig.c.  Once you get it to run, select a makefile according to
-the advice it prints out, and make any other changes it recommends.
-
-Look over the selected Makefile and adjust options as needed.  In particular
-you may want to change the CC and CFLAGS definitions.  For instance, if you
-are using GCC, set CC=gcc.  If you had to use any compiler switches to get
-ckconfig.c to work, make sure the same switches are in CFLAGS.
-
-If you are on a system that doesn't use makefiles, you'll need to set up
-project files (or whatever you do use) to compile all the source files and
-link them into executable files cjpeg and djpeg.  See the file lists in any of
-the makefiles to find out which files go into each program.  As a last resort,
-you can make a batch script that just compiles everything and links it all
-together; makefile.vms is an example of this (it's for VMS systems that have
-no make-like utility).
-
-
-STEP 2: EDIT JCONFIG.H
-======================
-
-Look over jconfig.h and adjust #defines to reflect the properties of your
-system and C compiler.  If you prefer, you can usually leave jconfig.h
-unmodified and add -Dsymbol switches to the Makefile's CFLAGS definition.
-(This is already done if you used a compiler-specific makefile in step 1.)
-However, putting the switches in the Makefile is a bad idea if you are going
-to incorporate the JPEG software into other programs --- you'd need to include
-the same -D switches in the other programs' Makefiles.  Better to change
-jconfig.h.
-
-If you have an ANSI-compliant C compiler, no changes should be necessary
-except perhaps for RIGHT_SHIFT_IS_UNSIGNED and TWO_FILE_COMMANDLINE.  For
-older compilers other changes may be needed, depending on what ANSI features
-are supported.
-
-If you don't know enough about C programming to understand the questions in
-jconfig.h, then use ckconfig.c to figure out what to change.  (See description
-of ckconfig.c in step 1.)
-
-A note about TWO_FILE_COMMANDLINE: defining this selects the command line
-syntax in which the input and output files are both named on the command line.
-If it's not defined, the output image goes to standard output, and the input
-can optionally come from standard input.  You MUST use two-file style on any
-system that doesn't cope well with binary data fed through stdin/stdout; this
-is true for most MS-DOS compilers, for example.  If you're not on a Unix
-system, it's probably safest to assume you need two-file style.  (But if your
-compiler provides either the Posix-standard fdopen() library routine or a
-Microsoft-compatible setmode() routine, you can use the Unix command line
-style, by defining USE_FDOPEN or USE_SETMODE respectively.)
-
-
-STEP 3: SELECT SYSTEM-DEPENDENT FILES
-=====================================
-
-A few places in the JPEG software are so system-dependent that we have to
-provide several different implementations and let you select the one you need.
-
-The only system-dependent file in the current version is jmemsys.c.  This file
-controls use of temporary files for big images that won't fit in main memory.
-You'll notice there is no file named jmemsys.c in the distribution; you must
-select one of the provided versions and copy, rename, or link it to jmemsys.c.
-Here are the provided versions:
-
-	jmemansi.c	This is a reasonably portable version that should
-			work on most ANSI and near-ANSI C compilers.  It uses
-			the ANSI-standard library routine tmpfile(), which not
-			all non-ANSI systems have.  On some systems tmpfile()
-			may put the temporary file in a non-optimal location;
-			if you don't like what it does, use jmemname.c.
-
-	jmemname.c	This version constructs the temp file name by itself.
-			For anything except a Unix machine, you'll need to
-			configure the select_file_name() routine appropriately;
-			see the comments near the head of jmemname.c.
-			If you use this version, define NEED_SIGNAL_CATCHER
-			in jconfig.h or in the Makefile to make sure the temp
-			files are removed if the program is aborted.
-
-	jmemnobs.c	(That stands for No Backing Store :-).  This will
-			compile on almost any system, but it assumes you
-			have enough main memory or virtual memory to hold
-			the biggest images you need to work with.
-
-	jmemdos.c	This should be used in most MS-DOS installations; see
-			the system-specific notes about MS-DOS for more info.
-			IMPORTANT: if you use this, also copy jmemdos.h to
-			jmemsys.h, replacing the standard version.  ALSO,
-			include the assembly file jmemdosa.asm in the programs.
-			(This last is already done if you used one of the
-			supplied MS-DOS-specific makefiles.)
-
-If you have plenty of (real or virtual) main memory, just use jmemnobs.c.
-"Plenty" means at least ten bytes for every pixel in the largest images
-you plan to process, so a lot of systems don't meet this criterion.
-If yours doesn't, try jmemansi.c first.  If that doesn't compile, you'll have
-to use jmemname.c; be sure to adjust select_file_name() for local conditions.
-You may also need to change unlink() to remove() in close_backing_store().
-
-Except with jmemnobs.c, you need to adjust the #define DEFAULT_MAX_MEM to a
-reasonable value for your system (either by editing jmemsys.c, or by adding
-a -D switch to the Makefile).  This value limits the amount of data space the
-program will attempt to allocate.  Code and static data space isn't counted,
-so the actual memory needs for cjpeg or djpeg are typically 100 to 150Kb more
-than the max-memory setting.  Larger max-memory settings reduce the amount of
-I/O needed to process a large image, but too large a value can result in
-"insufficient memory" failures.  On most Unix machines (and other systems with
-virtual memory), just set DEFAULT_MAX_MEM to several million and forget it.
-At the other end of the spectrum, for MS-DOS machines you probably can't go
-much above 300K to 400K.  (On MS-DOS the value refers to conventional memory;
-extended/expanded memory is handled separately by jmemdos.c.)
-
-
-STEP 4: MAKE
-============
-
-Now you should be able to "make" the software.
-
-If you have trouble with missing system include files or inclusion of the
-wrong ones, look at jinclude.h (or use ckconfig.c, if you are not a C expert).
-
-If your compiler complains about big_sarray_control and big_barray_control
-being undefined structures, you should be able to shut it up by adding
--DINCOMPLETE_TYPES_BROKEN to CFLAGS (or add #define INCOMPLETE_TYPES_BROKEN
-to jconfig.h).  If you don't have a getenv() library routine, define NO_GETENV.
-
-There are a fair number of routines that do not use all of their parameters;
-some compilers will issue warnings about this, which you can ignore.  Any
-other warning deserves investigation.
-
-
-STEP 5: TEST
-============
-
-As a quick test of functionality we've included a small sample image in
-several forms:
-	testorig.jpg	A reduced section of the well-known Lenna picture.
-	testimg.ppm	The output of djpeg testorig.jpg
-	testimg.gif	The output of djpeg -gif testorig.jpg
-	testimg.jpg	The output of cjpeg testimg.ppm
-(The two .jpg files aren't identical since JPEG is lossy.)  If you can
-generate duplicates of the testimg.* files then you probably have working
-programs.
-
-With most of the makefiles, "make test" will perform the necessary
-comparisons.  If you started with makefile.ansi or makefile.unix, and you
-defined TWO_FILE_COMMANDLINE, then change the makefile's test script to use
-two-file syntax (i.e., delete the ">" character from the invocations of cjpeg
-and djpeg).  The other makefiles will work with either command-line syntax.
-
-If you're using a makefile that doesn't provide the test option, run djpeg and
-cjpeg by hand to generate testout.ppm, testout.gif, and testout.jpg, then
-compare these to testimg.* with whatever binary file comparison tool you have.
-The files should be bit-for-bit identical.
-
-If the cjpeg test run fails with "Missing Huffman code table entry", it's a
-good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED.  Go back to step 2
-and run ckconfig.c.  (This is a good plan for any other test failure, too.)
-
-If you are using Unix (one-file) command line style on a non-Unix system,
-it's a good idea to check that binary I/O through stdin/stdout actually works.
-You should get the same results from "djpeg <testorig.jpg >out.ppm" as from
-"djpeg -outfile out.ppm  testorig.jpg".  Note that the non-Unix makefiles use
-the latter style and therefore do not exercise stdin/stdout.  If this test
-fails, try recompiling jcmain.c & jdmain.c with USE_SETMODE and/or USE_FDOPEN.
-
-If your choice of jmemsys.c was anything other than jmemnobs.c, you should
-test that temporary-file usage works.  Try "djpeg -gif -max 0 testorig.jpg"
-and make sure its output matches testimg.gif.  If you have any really large
-images handy, try compressing them with -optimize and/or decompressing with
--gif to make sure your DEFAULT_MAX_MEM setting is not too large.
-
-NOTE: this is far from an exhaustive test of the JPEG software; some modules,
-such as 1-pass color quantization, are not exercised at all.  It's just a quick
-test to give you some confidence that you haven't missed something major.
-
-
-STEP 6: INSTALLATION
-====================
-
-Once you're done with the above steps, you can install the software by copying
-the executable files (cjpeg and djpeg) to wherever you normally install
-programs.  On Unix systems, you'll also want to put cjpeg.1 and djpeg.1 in the
-corresponding manual directory.  (The makefiles don't support this step since
-there's such a wide variety of installation procedures on different systems.)
-
-To learn to use the programs, read the file USAGE (or manual pages cjpeg(1)
-and djpeg(1) on Unix).  Note that the man pages cjpeg.1/djpeg.1 only describe
-the Unix-style command line syntax; if you want to use these files with a
-version that uses two-file command line syntax, you'll have to modify the text
-accordingly.  The USAGE file describes both styles.
-
-
-OPTIMIZATION
-============
-
-Unless you own a Cray, you'll probably be interested in making the JPEG
-software go as fast as possible.  This section covers some machine-dependent
-optimizations you may want to try.  We suggest that before trying any of this,
-you first get the basic installation to pass the self-test (step 5 above).
-Repeat the self-test after any optimization to make sure that you haven't
-broken anything.
-
-The JPEG DCT routines perform a lot of multiplications.  These multiplications
-must yield 32-bit results, but none of their input values are more than 16
-bits wide.  On many machines, notably the 680x0 and 80x86 CPUs, a 16x16=>32
-bit multiply instruction is faster than a full 32x32=>32 bit multiply.
-Unfortunately there is no portable way to specify such a multiplication in C,
-but some compilers can generate one when you use the right combination of
-casts.  See the MULTIPLY macro definitions in jfwddct.c and jrevdct.c.
-If your compiler makes "int" be 32 bits and "short" be 16 bits, defining
-SHORTxSHORT_32 is fairly likely to work.  When experimenting with alternate
-definitions, be sure to test not only whether the code still works (use the
-self-test step), but also whether it is actually faster --- on some compilers,
-alternate definitions may compute the right answer, yet be slower than the
-default.  Timing cjpeg on a large PPM input file is the best way to check
-this, as the DCT will be the largest fraction of the runtime in that mode.
-(Note: some of the distributed compiler-specific makefiles already contain
--D switches to select an appropriate MULTIPLY definition.)
-
-If access to "short" arrays is slow on your machine, it may be a win to define
-type DCTELEM as int rather than as JCOEF (which is normally defined as short).
-This will cause the DCT routines to operate on int arrays instead of short
-arrays.  If shorts are slow and you have lots of memory to burn, you might
-even make JCOEF itself be int.
-
-If your compiler can compile function calls in-line, make sure the INLINE
-macro in jconfig.h is defined as the keyword that marks a function
-inline-able.  Some compilers have a switch that tells the compiler to inline
-any function it thinks is profitable (e.g., -finline-functions for gcc).
-Enabling such a switch is likely to make the compiled code bigger but faster.
-
-In general, it's worth trying the maximum optimization level of your compiler,
-and experimenting with any optional optimizations such as loop unrolling.
-(Unfortunately, far too many compilers have optimizer bugs ... be prepared to
-back off if the code fails self-test.)  If you do any experimentation along
-these lines, please report the optimal settings to jpeg-info@uunet.uu.net so
-we can mention them in future releases.  Be sure to specify your machine and
-compiler version.
-
-
-OPTIONAL STUFF
-==============
-
-Progress monitor:
-
-If you like, you can #define PROGRESS_REPORT (in jconfig.h or in the Makefile)
-to enable display of percent-done progress reports.  The routines provided in
-jcmain.c/jdmain.c merely print percentages to stderr, but you can customize
-them to do something fancier.
-
-Utah RLE file format support:
-
-We distribute the software with support for RLE image files (Utah Raster
-Toolkit format) disabled, because the RLE support won't compile without the
-Utah library.  If you have URT version 3.0, you can enable RLE support as
-follows:
-	1.  #define RLE_SUPPORTED in jconfig.h or in the Makefile.
-	2.  Add a -I option to CFLAGS in the Makefile for the directory
-	    containing the URT .h files (typically the "include"
-	    subdirectory of the URT distribution).
-	3.  Add -L... -lrle to LDLIBS in the Makefile, where ... specifies
-	    the directory containing the URT "librle.a" file (typically the
-	    "lib" subdirectory of the URT distribution).
-
-JPEG library:
-
-If you want to incorporate the JPEG code as subroutines in a larger program,
-we recommend that you make libjpeg.a, then link that into your surrounding
-program.  See file README for more info.
-
-CAUTION: When you use the JPEG code as subroutines, we recommend that you make
-any required configuration changes by modifying jconfig.h, not by adding -D
-switches to the Makefile.  Otherwise you must be sure to provide the same -D
-switches when compiling any program that includes the JPEG .h files, to ensure
-that the parameter structures are interpreted the same way.  (This is only
-critical for the first few symbols mentioned in jconfig.h, down through
-NEED_FAR_POINTERS.)
-
-Removing code:
-
-If you need to make a smaller version of the JPEG software, some optional
-functions can be removed at compile time.  See the xxx_SUPPORTED #defines in
-jconfig.h.  If at all possible, we recommend that you leave in decoder support
-for all valid JPEG files, to ensure that you can read anyone's output.
-Restricting your encoder, or removing optional functions like block smoothing,
-won't hurt compatibility.  Taking out support for image file formats that you
-don't use is the most painless way to make the programs smaller.

-Makefiles are provided for Manx Aztec C and SAS C.  I have also heard from
-people who have compiled with the free DICE compiler, using makefile.ansi as a
-starting point (set "CC= dcc" and "CFLAGS= -c -DAMIGA -DTWO_FILE_COMMANDLINE
--DNEED_SIGNAL_CATCHER" in the makefile).  For all compilers, we recommend you
-use jmemname.c as the system-dependent memory manager.  Assuming you have
--DAMIGA in the makefile, jmemname.c will put temporary files in JPEGTMP:.
-Change jmemname.c if you don't like this.
-
-
-Atari:
-
-The project files provided should work as-is with Pure C.  For Turbo C, change
-library filenames "PC..." to "TC..." in the project files for cjpeg.ttp and
-djpeg.ttp.  Don't forget to select a jmemsys.c file, see Step 3 (we recommend
-jmemansi.c).  Also adjust the DEFAULT_MAX_MEM setting --- you probably want it
-to be a couple hundred K less than your normal free memory.  Note that you
-must make jpeg.lib before making cjpeg.ttp or cjpeg.ttp.  You'll have to
-perform the self-test (Step 5) by hand.
-
-There is a bug in some older versions of the Turbo C library which causes the
-space used by temporary files created with "tmpfile()" not to be freed after
-an abnormal program exit.  If you check your disk afterwards, you will find
-cluster chains that are allocated but not used by a file.  This should not
-happen in cjpeg or djpeg, since we enable a signal catcher to explicitly close
-temp files before exiting.  But if you use the JPEG library with your own
-code, be sure to supply a signal catcher, or else use a different
-system-dependent memory manager.
-
-
-Cray:
-
-Should you be so fortunate as to be running JPEG on a Cray YMP, there is a
-compiler bug in Cray's Standard C versions prior to 3.1.  You'll need to
-insert a line reading "#pragma novector" just before the loop	
-    for (i = 1; i <= (int) htbl->bits[l]; i++)
-      huffsize[p++] = (char) l;
-in fix_huff_tbl (in V4A, line 42 of jchuff.c and line 39 of jdhuff.c).  The
-usual symptom of not adding this line is a core-dump.  See Cray's SPR 48222.
-
-
-HP/Apollo DOMAIN:
-
-With system release 10.4 or later, makefile.ansi should work OK.  If you have
-version 10.3.anything, you need to figure out whether you have the ANSI C
-compiler (version 6.7 or later) and whether you've installed the ANSI C
-include files (if so, the first line of <stdio.h> will mention ANSI C).
-If you have the ANSI C compiler but not the ANSI C include files, use
-makefile.ansi and add -DNONANSI_INCLUDES to CFLAGS.  If you have both,
-then makefile.ansi should work as is.  If neither, use makefile.unix.
-
-
-HP-UX:
-
-If you have HP-UX 7.05 or later with the "software development" C compiler,
-then you can use makefile.ansi.  Add "-Aa" to the CFLAGS line in the makefile
-to make the compiler work in ANSI mode.  If you have a pre-7.05 system, or if
-you are using the non-ANSI C compiler delivered with a minimum HP-UX 8.0
-system, then you must use makefile.unix (and do NOT add -Aa).  Also, adding
-"-lmalloc" to LDLIBS is recommended if you have libmalloc.a (it seems not to
-be present in minimum 8.0).
-
-On HP 9000 series 800 machines, the HP C compiler is buggy in revisions prior
-to A.08.07.  If you get complaints about "not a typedef name", you'll have to
-convert the code to K&R style (i.e., use makefile.unix).
-
-
-Macintosh MPW:
-
-We don't directly support MPW in the current release, but Larry Rosenstein
-reports that the JPEG code can be ported without very much trouble.  There's
-useful notes and conversion scripts in his kit for porting PBMPLUS to MPW.
-You can obtain the kit by FTP to ftp.apple.com, file /pub/lsr/pbmplus-port*.
-
-
-Macintosh Think C:
-
-You'll have to prepare project files for cjpeg and djpeg; we don't include
-those in the distribution since they are not text files.  The COBJECTS and
-DOBJECTS lists in makefile.unix show which files should be included in each
-project.  Also add the ANSI and Unix C libraries in a separate segment.  You
-may need to divide the JPEG files into more than one segment; you can do this
-pretty much as you please.
-
-If you have Think C version 5.0 you need not modify jconfig.h; instead you
-should turn on both the ANSI Settings and Language Extensions option buttons
-(so that both __STDC__ and THINK_C are predefined).  With version 4.0 you must
-edit jconfig.h.  (You can #define HAVE_STDC to do the right thing for all
-options except const; you must also #define const.)
-
-jcmain and jdmain are set up to provide the usual command-line interface
-by means of Think's ccommand() library routine.  A more Mac-like interface
-is in the works.
-
-
-MS-DOS, generic comments:
-
-The JPEG code is designed to be compiled with 80x86 "small" or "medium" memory
-models (i.e., data pointers are 16 bits unless explicitly declared "far"; code
-pointers can be either size).  You should be able to use small model to
-compile cjpeg or djpeg by itself, but you will probably have to go to medium
-model if you include the JPEG code in a larger application.  This shouldn't
-hurt performance much.  You *will* take a noticeable performance hit if you
-compile in a large-data memory model, and you should avoid "huge" model if at
-all possible.  Be sure that NEED_FAR_POINTERS is defined by jconfig.h or by
-the Makefile if you use a small-data model; be sure it is NOT defined if you
-use a large-data memory model.  (As distributed, jconfig.h defines
-NEED_FAR_POINTERS if MSDOS is defined.)
-
-The DOS-specific memory manager, jmemdos.c, should be used if possible.
-(Be sure to install jmemdos.h and jmemdosa.asm along with it.)  If you
-can't use jmemdos.c for some reason --- for example, because you don't have
-a Microsoft-compatible assembler to assemble jmemdosa.asm --- you'll have
-to fall back to jmemansi.c or jmemname.c.  IMPORTANT: if you use either of
-the latter two files, you will have to compile in a large-data memory model
-in order to get the right stdio library.  Too bad.
-
-None of the above advice applies if you are using a 386 flat-memory-space
-environment, such as DJGPP or Watcom C.  (And you should use one if you have
-it, as performance will be much better than 8086-compatible code!)  For
-flat-memory-space compilers, do NOT define NEED_FAR_POINTERS, and do NOT use
-jmemdos.c.  Use jmemnobs.c if the environment supplies adequate virtual
-memory, otherwise use jmemansi.c or jmemname.c.
-
-Most MS-DOS compilers treat stdin/stdout as text files, so you must use
-two-file command line style.  But if your compiler has either fdopen() or
-setmode(), you can use one-file style if you like.  To do this, define
-USE_FDOPEN or USE_SETMODE so that stdin/stdout will be set to binary mode.
-(USE_SETMODE seems to work with more DOS compilers than USE_FDOPEN.)  You
-should test that I/O through stdin/stdout produces the same results as I/O
-to explicitly named files... the "make test" procedures in the DOS-specific
-makefiles do NOT use stdin/stdout.
-
-If you add more switches to CFLAGS in the DOS-specific makefiles, you are
-likely to run up against DOS' 128-byte command line length limit.  In that
-case, remove some "-Dsymbol" switches from CFLAGS and instead put
-corresponding "#define symbol" lines at the head of jinclude.h.
-
-
-MS-DOS, Borland C:
-
-Be sure to convert all the source files to DOS text format (CR/LF newlines).
-Although Borland C will often work OK with unmodified Unix (LF newlines)
-source files, sometimes it will give bogus compile errors.
-"Illegal character '#'" is the most common such error.
-
-Some versions of Borland's MAKE erroneously display the warning message about
-creating jmemsys.c, even after you have done so.  If this happens to you,
-delete the four lines beginning with "jmemsys.c:" from the Makefile.
-
-If you want one-file command line style, define USE_SETMODE.  fdopen() does
-not work correctly.
-
-
-MS-DOS, DJGPP:
-
-Use makefile.ansi and jmemnobs.c, and put "-UMSDOS" in CFLAGS to undo the
-compiler's automatic definition of MSDOS.  Also put either "-DUSE_SETMODE" or
-"-DTWO_FILE_COMMANDLINE" in CFLAGS, depending on whether you prefer one-file
-or two-file command line style.  You'll also need to put the object-file lists
-into response files in order to circumvent DOS's 128-byte command line length
-limit at the final linking step.
-
-
-MS-DOS, Microsoft C:
-
-Old versions of MS C fail with an "out of macro expansion space" error
-because they can't cope with the macro TRACEMS8 (defined in jpegdata.h).
-If this happens to you, the easiest solution is to change TRACEMS8 to
-expand to nothing.  You'll lose the ability to dump out JPEG coefficient
-tables with djpeg -debug -debug, but at least you can compile.
-
-Original MS C 6.0 is buggy; it compiles incorrect code unless you turn off
-optimization (remove -O from CFLAGS).  That problem seems to have been fixed
-in 6.00A and later versions.  6.00A still generates a bogus "conditional
-expression is constant" warning in jrdppm.c, but the emitted code seems OK.
-
-If you want one-file command line style, define USE_SETMODE.  fdopen() does
-not work correctly, at least not in 6.00A.
-
-
-SGI:
-
-Use makefile.ansi, but set "AR2= ar -ts" rather than "AR2= ranlib".  Also
-make any changes recommended by ckconfig.c.
-
-
-Sun:
-
-Don't forget to add -DBSD to CFLAGS.  If you are using GCC on SunOS 4.0.1 or
-earlier, you will need to add -DNONANSI_INCLUDES to CFLAGS (your compiler may
-be ANSI, but your system include files aren't).  I've gotten conflicting
-reports on whether this is still necessary on SunOS 4.1 or later.

-=================================================================
-
-INTRODUCTION
-
-This distribution contains software to implement JPEG image compression and
-decompression.  JPEG (pronounced "jay-peg") is a standardized compression
-method for full-color and gray-scale images.  JPEG is designed to handle
-"real-world" scenes, for example scanned photographs.  Cartoons, line
-drawings, and other non-realistic images are not JPEG's strong suit; on this
-sort of material you may get poor image quality and/or little compression.
-
-JPEG is lossy, meaning that the output image is not necessarily identical to
-the input image.  Hence you should not use JPEG if you have to have identical
-output bits.  However, on typical real-world images, very good compression
-levels can be obtained with no visible change, and amazingly high compression
-is possible if you can tolerate a low-quality image.  You can trade off image
-quality against file size by adjusting the compressor's "quality" setting.
-
-This file describes usage of the standard programs "cjpeg" and "djpeg" that
-can be built directly from the distributed C code.  See the README file for
-hints on incorporating the JPEG software into other programs.
-
-If you are on a Unix machine you may prefer to read the Unix-style manual
-pages in files cjpeg.1 and djpeg.1.  But also see the HINTS section below,
-which is not present in either manual page.
-
-NOTE: the switch syntax has been redesigned since the v3 release of
-cjpeg/djpeg.  Switch names are now words instead of single letters.
-
-
-GENERAL USAGE
-
-We provide two programs, cjpeg to compress an image file into JPEG format,
-and djpeg to decompress a JPEG file back into a conventional image format.
-
-On Unix-like systems, you say:
-	cjpeg [switches] [imagefile] >jpegfile
-or
-	djpeg [switches] [jpegfile]  >imagefile
-The programs read the specified input file, or standard input if none is
-named.  They always write to standard output (with trace/error messages to
-standard error).  These conventions are handy for piping images between
-programs.
-
-On most non-Unix systems, you say:
-	cjpeg [switches] imagefile jpegfile
-or
-	djpeg [switches] jpegfile  imagefile
-i.e., both the input and output files are named on the command line.  This
-style is a little more foolproof, and it loses no functionality if you don't
-have pipes.  (You can get this style on Unix too, if you prefer, by defining
-TWO_FILE_COMMANDLINE when you compile the programs; see SETUP.)
-
-You can also say:
-	cjpeg [switches] -outfile jpegfile  imagefile
-or
-	djpeg [switches] -outfile imagefile  jpegfile
-This syntax works on all systems, so it is useful for scripts.
-
-The currently supported image file formats are: PPM (PBMPLUS color format),
-PGM (PBMPLUS gray-scale format), GIF, Targa, and RLE (Utah Raster Toolkit
-format).  (RLE is supported only if the URT library is available.)
-cjpeg recognizes the input image format automatically, with the exception
-of some Targa-format files.  You have to tell djpeg which format to generate.
-
-The only JPEG file format currently supported is the JFIF format.  Support for
-the TIFF 6.0 JPEG format will probably be added at some future date.
-
-All switch names may be abbreviated; for example, -grayscale may be written
--gray or -gr.  Most of the "basic" switches can be abbreviated to as little as
-one letter.  Upper and lower case are equivalent (-GIF is the same as -gif).
-British spellings are also accepted (e.g., -greyscale), though for brevity
-these are not mentioned below.
-
-
-CJPEG DETAILS
-
-The basic command line switches for cjpeg are:
-
-	-quality N	Scale quantization tables to adjust image quality.
-			Quality is 0 (worst) to 100 (best); default is 75.
-			(See below for more info.)
-
-	-grayscale	Create monochrome JPEG file from color input.
-			Be sure to use this switch when compressing a grayscale
-			GIF file, because cjpeg isn't bright enough to notice
-			whether a GIF file uses only shades of gray.  By
-			saying -grayscale, you'll get a smaller JPEG file that
-			takes less time to process.
-
-	-optimize	Perform optimization of entropy encoding parameters.
-			Without this, default encoding parameters are used.
-			-optimize usually makes the JPEG file a little smaller,
-			but cjpeg runs somewhat slower and needs much more
-			memory.  Image quality and speed of decompression are
-			unaffected by -optimize.
-
-	-targa		Input file is Targa format.  Targa files that contain
-			an "identification" field will not be automatically
-			recognized by cjpeg; for such files you must specify
-			-targa to make cjpeg treat the input as Targa format.
-
-The -quality switch lets you trade off compressed file size against quality of
-the reconstructed image: the higher the quality setting, the larger the JPEG
-file, and the closer the output image will be to the original input.  Normally
-you want to use the lowest quality setting (smallest file) that decompresses
-into something visually indistinguishable from the original image.  For this
-purpose the quality setting should be between 50 and 95; the default of 75 is
-often about right.  If you see defects at -quality 75, then go up 5 or 10
-counts at a time until you are happy with the output image.  (The optimal
-setting will vary from one image to another.)
-
--quality 100 will generate a quantization table of all 1's, eliminating loss
-in the quantization step (but there is still information loss in subsampling,
-as well as roundoff error).  This setting is mainly of interest for
-experimental purposes.  Quality values above about 95 are NOT recommended for
-normal use; the compressed file size goes up dramatically for hardly any gain
-in output image quality.
-
-In the other direction, quality values below 50 will produce very small files
-of low image quality.  Settings around 5 to 10 might be useful in preparing an
-index of a large image library, for example.  Try -quality 2 (or so) for some
-amusing Cubist effects.  (Note: quality values below about 25 generate 2-byte
-quantization tables, which are considered optional in the JPEG standard.
-cjpeg emits a warning message when you give such a quality value, because
-some commercial JPEG programs may be unable to decode the resulting file.)
-
-Switches for advanced users:
-
-	-maxmemory N	Set limit for amount of memory to use in processing
-			large images.  Value is in thousands of bytes, or
-			millions of bytes if "M" is attached to the number.
-			For example, -max 4m selects 4000000 bytes.  If more
-			space is needed, temporary files will be used.
-
-	-restart N	Emit a JPEG restart marker every N MCU rows, or every
-			N MCU blocks if "B" is attached to the number.
-			-restart 0 (the default) means no restart markers.
-
-	-smooth N	Smooth the input image to eliminate dithering noise.
-			N, ranging from 1 to 100, indicates the strength of
-			smoothing.  0 (the default) means no smoothing.
-
-	-verbose	Enable debug printout.  More -v's give more printout.
-	or  -debug	Also, version information is printed at startup.
-
-The -restart option inserts extra markers that allow a JPEG decoder to
-resynchronize after a transmission error.  Without restart markers, any damage
-to a compressed file will usually ruin the image from the point of the error
-to the end of the image; with restart markers, the damage is usually confined
-to the portion of the image up to the next restart marker.  Of course, the
-restart markers occupy extra space.  We recommend -restart 1 for images that
-will be transmitted across unreliable networks such as Usenet.
-
-The -smooth option filters the input to eliminate fine-scale noise.  This is
-often useful when converting GIF files to JPEG: a moderate smoothing factor of
-10 to 50 gets rid of dithering patterns in the input file, resulting in a
-smaller JPEG file and a better-looking image.  Too large a smoothing factor
-will visibly blur the image, however.
-
-Switches for wizards:
-
-	-arithmetic	Use arithmetic coding rather than Huffman coding.
-			(Not currently supported for legal reasons.)
-
-	-nointerleave	Generate noninterleaved JPEG file (not yet supported).
-
-	-qtables file	Use the quantization tables given in the specified
-			file.  The file should contain one to four tables
-			(64 values each) as plain text.  Comments preceded by
-			'#' may be included in the file.  The tables are
-			implicitly numbered 0,1,etc.  If -quality N is also
-			specified, the values in the file are scaled according
-			to cjpeg's quality scaling curve.
-
-	-sample HxV[,...]	Set JPEG sampling factors.  If you specify
-			fewer H/V pairs than there are components, the
-			remaining components are set to 1x1 sampling.  The
-			default setting is equivalent to "-sample 2x2".
-
-The "wizard" switches are intended for experimentation with JPEG.  If you
-don't know what you are doing, DON'T USE THEM.  You can easily produce files
-with worse image quality and/or poorer compression than you'll get from the
-default settings.  Furthermore, these switches should not be used when making
-files intended for general use, because not all JPEG implementations will
-support unusual JPEG parameter settings.
-
-
-DJPEG DETAILS
-
-The basic command line switches for djpeg are:
-
-	-colors N	Reduce image to at most N colors.  This reduces the
-	or -quantize N	number of colors used in the output image, so that it
-			can be displayed on a colormapped display or stored in
-			a colormapped file format.  For example, if you have
-			an 8-bit display, you'd need to reduce to 256 or fewer
-			colors.  (-colors is the recommended name, -quantize
-			is provided only for backwards compatibility.)
-
-	-gif		Select GIF output format.  Since GIF does not support
-			more than 256 colors, -colors 256 is assumed (unless
-			you specify a smaller number of colors).
-
-	-pnm		Select PBMPLUS (PPM/PGM) output format (this is the
-			default format).  PGM is emitted if the JPEG file is
-			gray-scale or if -grayscale is specified; otherwise
-			PPM is emitted.
-
-	-rle		Select RLE output format.  (Requires URT library.)
-
-	-targa		Select Targa output format.  Gray-scale format is
-			emitted if the JPEG file is gray-scale or if
-			-grayscale is specified; otherwise, colormapped format
-			is emitted if -colors is specified; otherwise, 24-bit
-			full-color format is emitted.
-
-Switches for advanced users:
-
-	-blocksmooth	Perform cross-block smoothing.  This is slow, quite
-			memory-intensive, and only seems to improve the image
-			at very low quality settings (-quality 10 to 20 or so).
-			At normal quality settings it may make things worse.
-
-	-grayscale	Force gray-scale output even if JPEG file is color.
-			Useful for viewing on monochrome displays.
-
-	-maxmemory N	Set limit for amount of memory to use in processing
-			large images.  Value is in thousands of bytes, or
-			millions of bytes if "M" is attached to the number.
-			For example, -max 4m selects 4000000 bytes.  If more
-			space is needed, temporary files will be used.
-
-	-nodither	Do not use dithering in color quantization.
-			By default, Floyd-Steinberg dithering is applied when
-			quantizing colors, but on some images dithering may
-			result in objectionable "graininess".  If that
-			happens, you can turn off dithering with -nodither.
-			-nodither is ignored unless you also say -colors N.
-
-	-onepass	Use one-pass instead of two-pass color quantization.
-			The one-pass method is faster and needs less memory,
-			but it produces a lower-quality image.  -onepass is
-			ignored unless you also say -colors N.  Also,
-			the one-pass method is always used for gray-scale
-			output (the two-pass method is no improvement then).
-
-	-verbose	Enable debug printout.  More -v's give more printout.
-	or  -debug	Also, version information is printed at startup.
-
-
-HINTS
-
-Color GIF files are not the ideal input for JPEG; JPEG is really intended for
-compressing full-color (24-bit) images.  In particular, don't try to convert
-cartoons, line drawings, and other images that have only a few distinct
-colors.  GIF works great on these, JPEG does not.  If you want to convert a
-GIF to JPEG, you should experiment with cjpeg's -quality and -smooth options
-to get a satisfactory conversion.  -smooth 10 or so is often helpful.
-
-Avoid running an image through a series of JPEG compression/decompression
-cycles.  Image quality loss will accumulate; after ten or so cycles the image
-may be noticeably worse than it was after one cycle.  It's best to use a
-lossless format while manipulating an image, then convert to JPEG format when
-you are ready to file the image away.
-
-The -optimize option to cjpeg is worth using when you are making a "final"
-version for posting or archiving.  It's also a win when you are using low
-quality settings to make very small JPEG files; the percentage improvement
-is often a lot more than it is on larger files.
-
-When making images to be posted on Usenet, we recommend using cjpeg's option
--restart 1.  This option limits the damage done to a compressed image by
-netnews transmission errors.
-
-The default memory usage limit (-maxmemory) is set when the software is
-compiled.  If you get an "insufficient memory" error, try specifying a smaller
--maxmemory value, even -maxmemory 0 to use the absolute minimum space.  You
-may want to recompile with a smaller default value if this happens often.
-
-On machines that have "environment" variables, you can define the environment
-variable JPEGMEM to set the default memory limit.  The value is specified as
-described for the -maxmemory switch.  JPEGMEM overrides the default value
-specified when the program was compiled, and itself is overridden by an
-explicit -maxmemory switch.
-
-On MS-DOS machines, -maxmemory is the amount of main (conventional) memory to
-use.  (Extended or expanded memory is also used if available.)  Most
-DOS-specific versions of this software do their own memory space estimation
-and do not need -maxmemory.
-
-djpeg with two-pass color quantization requires a good deal of memory; on
-MS-DOS machines it may run out of memory even with -maxmemory 0.  In that case
-you can still decompress, with some loss of image quality, by specifying
--onepass for one-pass quantization.
-
-If more space is needed than will fit in the available main memory (as
-determined by -maxmemory), temporary files will be used.  (MS-DOS versions
-will try to get extended or expanded memory first.)  The temporary files are
-often rather large: in typical cases they occupy three bytes per pixel, for
-example 3*800*600 = 1.44Mb for an 800x600 image.  If you don't have enough
-free disk space, leave out -optimize (for cjpeg) or specify -onepass (for
-djpeg).  On MS-DOS, the temporary files are created in the directory named by
-the TMP or TEMP environment variable, or in the current directory if neither
-of those exist.  Amiga implementations put the temp files in the directory
-named by JPEGTMP:, so be sure to assign JPEGTMP: to a disk partition with
-adequate free space.

----------- Here is the GhostScript file COPYING, referred to above ----------
------ These terms do NOT apply to the JPEG software itself; see README ------
-
-		    GHOSTSCRIPT GENERAL PUBLIC LICENSE
-		    (Clarified 11 Feb 1988)
-
- Copyright (C) 1988 Richard M. Stallman
- Everyone is permitted to copy and distribute verbatim copies of this
- license, but changing it is not allowed.  You can also use this wording
- to make the terms for other programs.
-
-  The license agreements of most software companies keep you at the
-mercy of those companies.  By contrast, our general public license is
-intended to give everyone the right to share Ghostscript.  To make sure
-that you get the rights we want you to have, we need to make
-restrictions that forbid anyone to deny you these rights or to ask you
-to surrender the rights.  Hence this license agreement.
-
-  Specifically, we want to make sure that you have the right to give
-away copies of Ghostscript, that you receive source code or else can get
-it if you want it, that you can change Ghostscript or use pieces of it
-in new free programs, and that you know you can do these things.
-
-  To make sure that everyone has such rights, we have to forbid you to
-deprive anyone else of these rights.  For example, if you distribute
-copies of Ghostscript, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must tell them their rights.
-
-  Also, for our own protection, we must make certain that everyone finds
-out that there is no warranty for Ghostscript.  If Ghostscript is
-modified by someone else and passed on, we want its recipients to know
-that what they have is not what we distributed, so that any problems
-introduced by others will not reflect on our reputation.
-
-  Therefore we (Richard M. Stallman and the Free Software Foundation,
-Inc.) make the following terms which say what you must do to be allowed
-to distribute or change Ghostscript.
-
-
-			COPYING POLICIES
-
-  1. You may copy and distribute verbatim copies of Ghostscript source
-code as you receive it, in any medium, provided that you conspicuously
-and appropriately publish on each copy a valid copyright and license
-notice "Copyright (C) 1989 Aladdin Enterprises.  All rights reserved.
-Distributed by Free Software Foundation, Inc." (or with whatever year is
-appropriate); keep intact the notices on all files that refer to this
-License Agreement and to the absence of any warranty; and give any other
-recipients of the Ghostscript program a copy of this License Agreement
-along with the program.  You may charge a distribution fee for the
-physical act of transferring a copy.
-
-  2. You may modify your copy or copies of Ghostscript or any portion of
-it, and copy and distribute such modifications under the terms of
-Paragraph 1 above, provided that you also do the following:
-
-    a) cause the modified files to carry prominent notices stating
-    that you changed the files and the date of any change; and
-
-    b) cause the whole of any work that you distribute or publish,
-    that in whole or in part contains or is a derivative of Ghostscript
-    or any part thereof, to be licensed at no charge to all third
-    parties on terms identical to those contained in this License
-    Agreement (except that you may choose to grant more extensive
-    warranty protection to some or all third parties, at your option).
-
-    c) You may charge a distribution fee for the physical act of
-    transferring a copy, and you may at your option offer warranty
-    protection in exchange for a fee.
-
-Mere aggregation of another unrelated program with this program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other program under the scope of these terms.
-
-  3. You may copy and distribute Ghostscript (or a portion or derivative
-of it, under Paragraph 2) in object code or executable form under the
-terms of Paragraphs 1 and 2 above provided that you also do one of the
-following:
-
-    a) accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    b) accompany it with a written offer, valid for at least three
-    years, to give any third party free (except for a nominal
-    shipping charge) a complete machine-readable copy of the
-    corresponding source code, to be distributed under the terms of
-    Paragraphs 1 and 2 above; or,
-
-    c) accompany it with the information you received as to where the
-    corresponding source code may be obtained.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form alone.)
-
-For an executable file, complete source code means all the source code for
-all modules it contains; but, as a special exception, it need not include
-source code for modules which are standard libraries that accompany the
-operating system on which the executable file runs.
-
-  4. You may not copy, sublicense, distribute or transfer Ghostscript
-except as expressly provided under this License Agreement.  Any attempt
-otherwise to copy, sublicense, distribute or transfer Ghostscript is
-void and your rights to use the program under this License agreement
-shall be automatically terminated.  However, parties who have received
-computer software programs from you with this License Agreement will not
-have their licenses terminated so long as such parties remain in full
-compliance.
-
-  5. If you wish to incorporate parts of Ghostscript into other free
-programs whose distribution conditions are different, write to the Free
-Software Foundation at 675 Mass Ave, Cambridge, MA 02139.  We have not
-yet worked out a simple rule that can be stated here, but we will often
-permit this.  We will be guided by the two goals of preserving the free
-status of all derivatives of our free software and of promoting the
-sharing and reuse of software.
-
-Your comments and suggestions about our licensing policies and our
-software are welcome!  Please contact the Free Software Foundation,
-Inc., 675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.
-
-		       NO WARRANTY
-
-  BECAUSE GHOSTSCRIPT IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY
-NO WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW.  EXCEPT
-WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, RICHARD
-M. STALLMAN, ALADDIN ENTERPRISES, L. PETER DEUTSCH, AND/OR OTHER PARTIES
-PROVIDE GHOSTSCRIPT "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
-EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
-WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE
-ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF GHOSTSCRIPT IS WITH
-YOU.  SHOULD GHOSTSCRIPT PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
-NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M.
-STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., L. PETER DEUTSCH, ALADDIN
-ENTERPRISES, AND/OR ANY OTHER PARTY WHO MAY MODIFY AND REDISTRIBUTE
-GHOSTSCRIPT AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
-ANY LOST PROFITS, LOST MONIES, OR OTHER SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
-(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
-INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A FAILURE OF THE
-PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) GHOSTSCRIPT, EVEN IF YOU
-HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM
-BY ANY OTHER PARTY.

+CHANGE LOG for Independent JPEG Group's JPEG software
+
+
+Version 8b  16-May-2010
+-----------------------
+
+Repair problem in new memory source manager with corrupt JPEG data.
+Thank to Ted Campbell and Samuel Chun for the report.
+
+
+Version 8a  28-Feb-2010
+-----------------------
+
+Writing tables-only datastreams via jpeg_write_tables works again.
+
+Support 32-bit BMPs (RGB image with Alpha channel) for read in cjpeg.
+Thank to Brett Blackham for the suggestion.
+
+
+Version 8  10-Jan-2010
+----------------------
+
+Add sanity check in BMP reader module to avoid cjpeg crash for empty input
+image (thank to Isaev Ildar of ISP RAS, Moscow, RU for reporting this error).
+
+Add data source and destination managers for read from and write to
+memory buffers.  New API functions jpeg_mem_src and jpeg_mem_dest.
+Thank to Roberto Boni from Italy for the suggestion.
+
+
+Version 7  27-Jun-2009
+----------------------
+
+cjpeg -quality option has been extended for support of separate quality
+settings for luminance and chrominance (or in general, for every provided
+quantization table slot).
+New API function jpeg_default_qtables() and q_scale_factor array in library.
+
+Support arithmetic entropy encoding and decoding.
+Added files jaricom.c, jcarith.c, jdarith.c.
+
+jpegtran has a new "lossless" cropping feature.
+
+Implement -perfect option in jpegtran, new API function
+jtransform_perfect_transform() in transupp. (DP 204_perfect.dpatch)
+
+Better error messages for jpegtran fopen failure.
+(DP 203_jpegtran_errmsg.dpatch)
+
+Fix byte order issue with 16bit PPM/PGM files in rdppm.c/wrppm.c:
+according to Netpbm, the de facto standard implementation of the PNM formats,
+the most significant byte is first. (DP 203_rdppm.dpatch)
+
+Add -raw option to rdjpgcom not to mangle the output.
+(DP 205_rdjpgcom_raw.dpatch)
+
+Make rdjpgcom locale aware. (DP 201_rdjpgcom_locale.dpatch)
+
+Add extern "C" to jpeglib.h.
+This avoids the need to put extern "C" { ... } around #include "jpeglib.h"
+in your C++ application.  Defining the symbol DONT_USE_EXTERN_C in the
+configuration prevents this. (DP 202_jpeglib.h_c++.dpatch)
+
+
+Version 6b  27-Mar-1998
+-----------------------
+
+jpegtran has new features for lossless image transformations (rotation
+and flipping) as well as "lossless" reduction to grayscale.
+
+jpegtran now copies comments by default; it has a -copy switch to enable
+copying all APPn blocks as well, or to suppress comments.  (Formerly it
+always suppressed comments and APPn blocks.)  jpegtran now also preserves
+JFIF version and resolution information.
+
+New decompressor library feature: COM and APPn markers found in the input
+file can be saved in memory for later use by the application.  (Before,
+you had to code this up yourself with a custom marker processor.)
+
+There is an unused field "void * client_data" now in compress and decompress
+parameter structs; this may be useful in some applications.
+
+JFIF version number information is now saved by the decoder and accepted by
+the encoder.  jpegtran uses this to copy the source file's version number,
+to ensure "jpegtran -copy all" won't create bogus files that contain JFXX
+extensions but claim to be version 1.01.  Applications that generate their
+own JFXX extension markers also (finally) have a supported way to cause the
+encoder to emit JFIF version number 1.02.
+
+djpeg's trace mode reports JFIF 1.02 thumbnail images as such, rather
+than as unknown APP0 markers.
+
+In -verbose mode, djpeg and rdjpgcom will try to print the contents of
+APP12 markers as text.  Some digital cameras store useful text information
+in APP12 markers.
+
+Handling of truncated data streams is more robust: blocks beyond the one in
+which the error occurs will be output as uniform gray, or left unchanged
+if decoding a progressive JPEG.  The appearance no longer depends on the
+Huffman tables being used.
+
+Huffman tables are checked for validity much more carefully than before.
+
+To avoid the Unisys LZW patent, djpeg's GIF output capability has been
+changed to produce "uncompressed GIFs", and cjpeg's GIF input capability
+has been removed altogether.  We're not happy about it either, but there
+seems to be no good alternative.
+
+The configure script now supports building libjpeg as a shared library
+on many flavors of Unix (all the ones that GNU libtool knows how to
+build shared libraries for).  Use "./configure --enable-shared" to
+try this out.
+
+New jconfig file and makefiles for Microsoft Visual C++ and Developer Studio.
+Also, a jconfig file and a build script for Metrowerks CodeWarrior
+on Apple Macintosh.  makefile.dj has been updated for DJGPP v2, and there
+are miscellaneous other minor improvements in the makefiles.
+
+jmemmac.c now knows how to create temporary files following Mac System 7
+conventions.
+
+djpeg's -map switch is now able to read raw-format PPM files reliably.
+
+cjpeg -progressive -restart no longer generates any unnecessary DRI markers.
+
+Multiple calls to jpeg_simple_progression for a single JPEG object
+no longer leak memory.
+
+
+Version 6a  7-Feb-96
+--------------------
+
+Library initialization sequence modified to detect version mismatches
+and struct field packing mismatches between library and calling application.
+This change requires applications to be recompiled, but does not require
+any application source code change.
+
+All routine declarations changed to the style "GLOBAL(type) name ...",
+that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the
+routine's return type as an argument.  This makes it possible to add
+Microsoft-style linkage keywords to all the routines by changing just
+these macros.  Note that any application code that was using these macros
+will have to be changed.
+
+DCT coefficient quantization tables are now stored in normal array order
+rather than zigzag order.  Application code that calls jpeg_add_quant_table,
+or otherwise manipulates quantization tables directly, will need to be
+changed.  If you need to make such code work with either older or newer
+versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is
+recommended.
+
+djpeg's trace capability now dumps DQT tables in natural order, not zigzag
+order.  This allows the trace output to be made into a "-qtables" file
+more easily.
+
+New system-dependent memory manager module for use on Apple Macintosh.
+
+Fix bug in cjpeg's -smooth option: last one or two scanlines would be
+duplicates of the prior line unless the image height mod 16 was 1 or 2.
+
+Repair minor problems in VMS, BCC, MC6 makefiles.
+
+New configure script based on latest GNU Autoconf.
+
+Correct the list of include files needed by MetroWerks C for ccommand().
+
+Numerous small documentation updates.
+
+
+Version 6  2-Aug-95
+-------------------
+
+Progressive JPEG support: library can read and write full progressive JPEG
+files.  A "buffered image" mode supports incremental decoding for on-the-fly
+display of progressive images.  Simply recompiling an existing IJG-v5-based
+decoder with v6 should allow it to read progressive files, though of course
+without any special progressive display.
+
+New "jpegtran" application performs lossless transcoding between different
+JPEG formats; primarily, it can be used to convert baseline to progressive
+JPEG and vice versa.  In support of jpegtran, the library now allows lossless
+reading and writing of JPEG files as DCT coefficient arrays.  This ability
+may be of use in other applications.
+
+Notes for programmers:
+* We changed jpeg_start_decompress() to be able to suspend; this makes all
+decoding modes available to suspending-input applications.  However,
+existing applications that use suspending input will need to be changed
+to check the return value from jpeg_start_decompress().  You don't need to
+do anything if you don't use a suspending data source.
+* We changed the interface to the virtual array routines: access_virt_array
+routines now take a count of the number of rows to access this time.  The
+last parameter to request_virt_array routines is now interpreted as the
+maximum number of rows that may be accessed at once, but not necessarily
+the height of every access.
+
+
+Version 5b  15-Mar-95
+---------------------
+
+Correct bugs with grayscale images having v_samp_factor > 1.
+
+jpeg_write_raw_data() now supports output suspension.
+
+Correct bugs in "configure" script for case of compiling in
+a directory other than the one containing the source files.
+
+Repair bug in jquant1.c: sometimes didn't use as many colors as it could.
+
+Borland C makefile and jconfig file work under either MS-DOS or OS/2.
+
+Miscellaneous improvements to documentation.
+
+
+Version 5a  7-Dec-94
+--------------------
+
+Changed color conversion roundoff behavior so that grayscale values are
+represented exactly.  (This causes test image files to change.)
+
+Make ordered dither use 16x16 instead of 4x4 pattern for a small quality
+improvement.
+
+New configure script based on latest GNU Autoconf.
+Fix configure script to handle CFLAGS correctly.
+Rename *.auto files to *.cfg, so that configure script still works if
+file names have been truncated for DOS.
+
+Fix bug in rdbmp.c: didn't allow for extra data between header and image.
+
+Modify rdppm.c/wrppm.c to handle 2-byte raw PPM/PGM formats for 12-bit data.
+
+Fix several bugs in rdrle.c.
+
+NEED_SHORT_EXTERNAL_NAMES option was broken.
+
+Revise jerror.h/jerror.c for more flexibility in message table.
+
+Repair oversight in jmemname.c NO_MKTEMP case: file could be there
+but unreadable.
+
+
+Version 5  24-Sep-94
+--------------------
+
+Version 5 represents a nearly complete redesign and rewrite of the IJG
+software.  Major user-visible changes include:
+  * Automatic configuration simplifies installation for most Unix systems.
+  * A range of speed vs. image quality tradeoffs are supported.
+    This includes resizing of an image during decompression: scaling down
+    by a factor of 1/2, 1/4, or 1/8 is handled very efficiently.
+  * New programs rdjpgcom and wrjpgcom allow insertion and extraction
+    of text comments in a JPEG file.
+
+The application programmer's interface to the library has changed completely.
+Notable improvements include:
+  * We have eliminated the use of callback routines for handling the
+    uncompressed image data.  The application now sees the library as a
+    set of routines that it calls to read or write image data on a
+    scanline-by-scanline basis.
+  * The application image data is represented in a conventional interleaved-
+    pixel format, rather than as a separate array for each color channel.
+    This can save a copying step in many programs.
+  * The handling of compressed data has been cleaned up: the application can
+    supply routines to source or sink the compressed data.  It is possible to
+    suspend processing on source/sink buffer overrun, although this is not
+    supported in all operating modes.
+  * All static state has been eliminated from the library, so that multiple
+    instances of compression or decompression can be active concurrently.
+  * JPEG abbreviated datastream formats are supported, ie, quantization and
+    Huffman tables can be stored separately from the image data.
+  * And not only that, but the documentation of the library has improved
+    considerably!
+
+
+The last widely used release before the version 5 rewrite was version 4A of
+18-Feb-93.  Change logs before that point have been discarded, since they
+are not of much interest after the rewrite.

+.PP
+The \fB-quality\fR option has been extended in this version of \fBcjpeg\fR to
+support separate quality settings for luminance and chrominance (or, in
+general, separate settings for every quantization table slot.)  The principle
+is the same as chrominance subsampling:  since the human eye is more sensitive
+to spatial changes in brightness than spatial changes in color, the chrominance
+components can be quantized more than the luminance components without
+incurring any visible image quality loss.  However, unlike subsampling, this
+feature reduces data in the frequency domain instead of the spatial domain,
+which allows for more fine-grained control.  This option is useful in
+quality-sensitive applications, for which the artifacts generated by
+subsampling may be unacceptable.
+.PP
+The \fB-quality\fR option accepts a comma-separated list of parameters, which
+respectively refer to the quality levels that should be assigned to the
+quantization table slots.  If there are more q-table slots than parameters,
+then the last parameter is replicated.  Thus, if only one quality parameter is
+given, this is used for both luminance and chrominance (slots 0 and 1,
+respectively), preserving the legacy behavior of cjpeg v6b and prior.
+More (or customized) quantization tables can be set with the \fB-qtables\fR
+option and assigned to components with the \fB-qslots\fR option (see the

+.BR CAUTION:
+For this setting to be useful, be sure to pass an argument of \fB-sample 1x1\fR

+The
+.B \-progressive
+switch creates a "progressive JPEG" file.  In this type of JPEG file, the data
+is stored in multiple scans of increasing quality.  If the file is being
+transmitted over a slow communications link, the decoder can use the first
+scan to display a low-quality image very quickly, and can then improve the
+display with each subsequent scan.  The final image is exactly equivalent to a
+standard JPEG file of the same quality setting, and the total file size is

-Arithmetic coding and interleaved output not yet supported.
+Support for GIF input files was removed in cjpeg v6b due to concerns over
+the Unisys LZW patent.  Although this patent expired in 2006, cjpeg still
+lacks GIF support, for these historical reasons.  (Conversion of GIF files to
+JPEG is usually a bad idea anyway.)

-Not all variants of Targa file format are supported.

 The

+.B \-targa
 switch is not a bug, it's a feature.  (It would be a bug if the Targa format
 designers had not been clueless.)

+ * Looking at additional bytes would require one of these approaches:

+ * The most portable solution for file types that can't be identified by their

+IJG JPEG LIBRARY:  CODING RULES
+
+Copyright (C) 1991-1996, Thomas G. Lane.
+This file is part of the Independent JPEG Group's software.
+For conditions of distribution and use, see the accompanying README file.
+
+
+Since numerous people will be contributing code and bug fixes, it's important
+to establish a common coding style.  The goal of using similar coding styles
+is much more important than the details of just what that style is.
+
+In general we follow the recommendations of "Recommended C Style and Coding
+Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and
+Brader).  This document is available in the IJG FTP archive (see
+jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).
+
+Block comments should be laid out thusly:
+
+/*
+ *  Block comments in this style.
+ */
+
+We indent statements in K&R style, e.g.,
+	if (test) {
+	  then-part;
+	} else {
+	  else-part;
+	}
+with two spaces per indentation level.  (This indentation convention is
+handled automatically by GNU Emacs and many other text editors.)
+
+Multi-word names should be written in lower case with underscores, e.g.,
+multi_word_name (not multiWordName).  Preprocessor symbols and enum constants
+are similar but upper case (MULTI_WORD_NAME).  Names should be unique within
+the first fifteen characters.  (On some older systems, global names must be
+unique within six characters.  We accommodate this without cluttering the
+source code by using macros to substitute shorter names.)
+
+We use function prototypes everywhere; we rely on automatic source code
+transformation to feed prototype-less C compilers.  Transformation is done
+by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).
+ansi2knr is not very bright, so it imposes a format requirement on function
+declarations: the function name MUST BEGIN IN COLUMN 1.  Thus all functions
+should be written in the following style:
+
+LOCAL(int *)
+function_name (int a, char *b)
+{
+    code...
+}
+
+Note that each function definition must begin with GLOBAL(type), LOCAL(type),
+or METHODDEF(type).  These macros expand to "static type" or just "type" as
+appropriate.  They provide a readable indication of the routine's usage and
+can readily be changed for special needs.  (For instance, special linkage
+keywords can be inserted for use in Windows DLLs.)
+
+ansi2knr does not transform method declarations (function pointers in
+structs).  We handle these with a macro JMETHOD, defined as
+	#ifdef HAVE_PROTOTYPES
+	#define JMETHOD(type,methodname,arglist)  type (*methodname) arglist
+	#else
+	#define JMETHOD(type,methodname,arglist)  type (*methodname) ()
+	#endif
+which is used like this:
+	struct function_pointers {
+	  JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp));
+	  JMETHOD(void, term_entropy_encoder, (void));
+	};
+Note the set of parentheses surrounding the parameter list.
+
+A similar solution is used for forward and external function declarations
+(see the EXTERN and JPP macros).
+
+If the code is to work on non-ANSI compilers, we cannot rely on a prototype
+declaration to coerce actual parameters into the right types.  Therefore, use
+explicit casts on actual parameters whenever the actual parameter type is not
+identical to the formal parameter.  Beware of implicit conversions to "int".
+
+It seems there are some non-ANSI compilers in which the sizeof() operator
+is defined to return int, yet size_t is defined as long.  Needless to say,
+this is brain-damaged.  Always use the SIZEOF() macro in place of sizeof(),
+so that the result is guaranteed to be of type size_t.
+
+
+The JPEG library is intended to be used within larger programs.  Furthermore,
+we want it to be reentrant so that it can be used by applications that process
+multiple images concurrently.  The following rules support these requirements:
+
+1. Avoid direct use of file I/O, "malloc", error report printouts, etc;
+pass these through the common routines provided.
+
+2. Minimize global namespace pollution.  Functions should be declared static
+wherever possible.  (Note that our method-based calling conventions help this
+a lot: in many modules only the initialization function will ever need to be
+called directly, so only that function need be externally visible.)  All
+global function names should begin with "jpeg_", and should have an
+abbreviated name (unique in the first six characters) substituted by macro
+when NEED_SHORT_EXTERNAL_NAMES is set.
+
+3. Don't use global variables; anything that must be used in another module
+should be in the common data structures.
+
+4. Don't use static variables except for read-only constant tables.  Variables
+that should be private to a module can be placed into private structures (see
+the system architecture document, structure.txt).
+
+5. Source file names should begin with "j" for files that are part of the
+library proper; source files that are not part of the library, such as cjpeg.c
+and djpeg.c, do not begin with "j".  Keep source file names to eight
+characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers.  Keep
+compression and decompression code in separate source files --- some
+applications may want only one half of the library.
+
+Note: these rules (particularly #4) are not followed religiously in the

-	JPEG SYSTEM CODING RULES		27-SEP-91
-
-Since numerous people will be contributing code and bug fixes, it's important
-to establish a common coding style.  The goal of using similar coding styles
-is much more important than the details of just what that style is.
-
-I suggest we follow the recommendations of "Recommended C Style and Coding
-Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and
-Brader).  I have placed a copy of this document in the jpeg FTP archive (see
-jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).
-
-Unless someone has a real strong objection, let's do block comments thusly:
-
-/*
- *  Block comments in this style.
- */
-
-and indent statements in K&R style, e.g.,
-
-	if (test) {
-	    then-part;
-	} else {
-	    else-part;
-	}
-
-I suggest that multi-word names be written in the style multi_word_name
-rather than multiWordName, but I am open to argument on this.
-
-
-I would like to use function prototypes everywhere, and rely on automatic
-source code transformation to feed non-ANSI C compilers.  The best tool
-I have so far found for this is 'ansi2knr.c', which is part of Ghostscript.
-ansi2knr is not very bright, so it imposes a format requirement on function
-declarations: the function name MUST BEGIN IN COLUMN 1.  Thus all functions
-should be written in the following style:
-
-static int *
-function_name (int a, char *b)
-{
-    code...
-}
-
-ansi2knr won't help with method declarations (function pointers in structs).
-I suggest we use a macro to declare method pointers, something like this:
-
-#ifdef PROTO
-#define METHOD(type,methodname,arglist)  type (*methodname) arglist
-#else
-#define METHOD(type,methodname,arglist)  type (*methodname) ()
-#endif
-
-which is used like this:
-
-struct function_pointers {
-	METHOD(void, init_entropy_encoder, (functptrs fptrs, jparms *jp));
-	METHOD(void, term_entropy_encoder, (void));
-};
-
-Note the set of parentheses surrounding the parameter list.
-
-A similar solution is used for external function declarations (see the PP
-macro in jpegdata.h).
-
-If the code is to work on non-ANSI compilers, you cannot rely on a prototype
-declaration to coerce actual parameters into the right types.  Therefore, use
-explicit casts on actual parameters whenever the actual parameter type is not
-identical to the formal parameter.  Beware of implicit conversions to "int".
-
-It seems there are some non-ANSI compilers in which the sizeof() operator
-is defined to return int, while size_t is defined as long.  Needless to say,
-this is brain-damaged.  Always use the SIZEOF() macro in place of sizeof(),
-so that the result is guaranteed to be of type size_t.
-
-
-We can expect that the JPEG compressor and decompressor will be incorporated
-into larger programs.  Therefore, the following rules are important:
-
-1. Avoid direct use of any file I/O, "malloc", error report printouts, etc;
-pass these through the common routines provided.
-
-2. Assume that the JPEG code may be invoked more than once per program run;
-therefore, do not rely on static initialization of variables, and be careful
-to release all allocated storage at the end of processing.
-
-3. Minimize global namespace pollution.  Functions should be declared static
-wherever possible.  (Note that our method-based calling conventions help this
-a lot: in many modules only the method-selector function will ever need to be
-called directly, so only that function need be externally visible.)  All
-global function names should begin with "j", and should be unique in the first
-six characters for portability reasons.
-Don't use global variables at all; anything that must be used in another
-module should be put into parameters (there'll be some large structs passed
-around for this purpose).
-
-4. Source file names should also begin with "j"; remember to keep them to
-eight characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers.
-Do not put code for both compression and decompression into the same source
-file.

- * output component representing an index into a color map).  You should use
- * colormapped mode to write to a colormapped display screen or output file.

- * precision.  In any other case, you should not depend on the colormap
- * entries having any particular order.
- * To get colormapped output, set cinfo->quantize_colors to TRUE and set
- * cinfo->desired_number_of_colors to the maximum number of entries in the
- * colormap.  This can be done either in your main routine or in
- * d_ui_method_selection.  For grayscale quantization, also set
- * cinfo->two_pass_quantize to FALSE to ensure the 1-pass quantizer is used
- * (presently this is the default, but it may not be so in the future).
- *
- * The output file writing modules (jwrppm.c, jwrgif.c, jwrtarga.c, etc) may be

+"jpegtran" uses the library to do lossless conversion between different
+variants of JPEG.  There are also two stand-alone applications,
+"rdjpgcom" and "wrjpgcom".
+
+
+THE JPEG LIBRARY
+================
+
+Include files:
+
+jpeglib.h	JPEG library's exported data and function declarations.
+jconfig.h	Configuration declarations.  Note: this file is not present
+		in the distribution; it is generated during installation.
+jmorecfg.h	Additional configuration declarations; need not be changed
+		for a standard installation.
+jerror.h	Declares JPEG library's error and trace message codes.
+jinclude.h	Central include file used by all IJG .c files to reference
+		system include files.
+jpegint.h	JPEG library's internal data structures.
+jchuff.h	Private declarations for Huffman encoder modules.
+jdhuff.h	Private declarations for Huffman decoder modules.
+jdct.h		Private declarations for forward & reverse DCT subsystems.
+jmemsys.h	Private declarations for memory management subsystem.
+jversion.h	Version information.
+
+Applications using the library should include jpeglib.h (which in turn
+includes jconfig.h and jmorecfg.h).  Optionally, jerror.h may be included
+if the application needs to reference individual JPEG error codes.  The
+other include files are intended for internal use and would not normally
+be included by an application program.  (cjpeg/djpeg/etc do use jinclude.h,
+since its function is to improve portability of the whole IJG distribution.
+Most other applications will directly include the system include files they
+want, and hence won't need jinclude.h.)
+
+
+C source code files:
+
+These files contain most of the functions intended to be called directly by
+an application program:
+
+jcapimin.c	Application program interface: core routines for compression.
+jcapistd.c	Application program interface: standard compression.
+jdapimin.c	Application program interface: core routines for decompression.
+jdapistd.c	Application program interface: standard decompression.
+jcomapi.c	Application program interface routines common to compression
+		and decompression.
+jcparam.c	Compression parameter setting helper routines.
+jctrans.c	API and library routines for transcoding compression.
+jdtrans.c	API and library routines for transcoding decompression.
+
+Compression side of the library:
+
+jcinit.c	Initialization: determines which other modules to use.
+jcmaster.c	Master control: setup and inter-pass sequencing logic.
+jcmainct.c	Main buffer controller (preprocessor => JPEG compressor).
+jcprepct.c	Preprocessor buffer controller.
+jccoefct.c	Buffer controller for DCT coefficient buffer.
+jccolor.c	Color space conversion.
+jcsample.c	Downsampling.
+jcdctmgr.c	DCT manager (DCT implementation selection & control).
+jfdctint.c	Forward DCT using slow-but-accurate integer method.
+jfdctfst.c	Forward DCT using faster, less accurate integer method.
+jfdctflt.c	Forward DCT using floating-point arithmetic.
+jchuff.c	Huffman entropy coding for sequential JPEG.
+jcphuff.c	Huffman entropy coding for progressive JPEG.
+jcarith.c	Arithmetic entropy coding.
+jcmarker.c	JPEG marker writing.
+jdatadst.c	Data destination managers for memory and stdio output.
+
+Decompression side of the library:
+
+jdmaster.c	Master control: determines which other modules to use.
+jdinput.c	Input controller: controls input processing modules.
+jdmainct.c	Main buffer controller (JPEG decompressor => postprocessor).
+jdcoefct.c	Buffer controller for DCT coefficient buffer.
+jdpostct.c	Postprocessor buffer controller.
+jdmarker.c	JPEG marker reading.
+jdhuff.c	Huffman entropy decoding for sequential JPEG.
+jdphuff.c	Huffman entropy decoding for progressive JPEG.
+jdarith.c	Arithmetic entropy decoding.
+jddctmgr.c	IDCT manager (IDCT implementation selection & control).
+jidctint.c	Inverse DCT using slow-but-accurate integer method.
+jidctfst.c	Inverse DCT using faster, less accurate integer method.
+jidctflt.c	Inverse DCT using floating-point arithmetic.
+jidctred.c	Inverse DCTs with reduced-size outputs.
+jdsample.c	Upsampling.
+jdcolor.c	Color space conversion.
+jdmerge.c	Merged upsampling/color conversion (faster, lower quality).
+jquant1.c	One-pass color quantization using a fixed-spacing colormap.
+jquant2.c	Two-pass color quantization using a custom-generated colormap.
+		Also handles one-pass quantization to an externally given map.
+jdatasrc.c	Data source managers for memory and stdio input.
+
+Support files for both compression and decompression:
+
+jaricom.c	Tables for common use in arithmetic entropy encoding and
+		decoding routines.
+jerror.c	Standard error handling routines (application replaceable).
+jmemmgr.c	System-independent (more or less) memory management code.
+jutils.c	Miscellaneous utility routines.
+
+jmemmgr.c relies on a system-dependent memory management module.  The IJG
+distribution includes the following implementations of the system-dependent
+module:
+
+jmemnobs.c	"No backing store": assumes adequate virtual memory exists.
+jmemansi.c	Makes temporary files with ANSI-standard routine tmpfile().
+jmemname.c	Makes temporary files with program-generated file names.
+jmemdos.c	Custom implementation for MS-DOS (16-bit environment only):
+		can use extended and expanded memory as well as temp files.
+jmemmac.c	Custom implementation for Apple Macintosh.
+
+Exactly one of the system-dependent modules should be configured into an
+installed JPEG library (see install.txt for hints about which one to use).
+On unusual systems you may find it worthwhile to make a special
+system-dependent memory manager.
+
+
+Non-C source code files:
+
+jmemdosa.asm	80x86 assembly code support for jmemdos.c; used only in
+		MS-DOS-specific configurations of the JPEG library.
+
+
+CJPEG/DJPEG/JPEGTRAN
+====================
+
+Include files:
+
+cdjpeg.h	Declarations shared by cjpeg/djpeg/jpegtran modules.
+cderror.h	Additional error and trace message codes for cjpeg et al.
+transupp.h	Declarations for jpegtran support routines in transupp.c.
+
+C source code files:
+
+cjpeg.c		Main program for cjpeg.
+djpeg.c		Main program for djpeg.
+jpegtran.c	Main program for jpegtran.
+cdjpeg.c	Utility routines used by all three programs.
+rdcolmap.c	Code to read a colormap file for djpeg's "-map" switch.
+rdswitch.c	Code to process some of cjpeg's more complex switches.
+		Also used by jpegtran.
+transupp.c	Support code for jpegtran: lossless image manipulations.
+
+Image file reader modules for cjpeg:
+
+rdbmp.c		BMP file input.
+rdgif.c		GIF file input (now just a stub).
+rdppm.c		PPM/PGM file input.
+rdrle.c		Utah RLE file input.
+rdtarga.c	Targa file input.
+
+Image file writer modules for djpeg:
+
+wrbmp.c		BMP file output.
+wrgif.c		GIF file output (a mere shadow of its former self).
+wrppm.c		PPM/PGM file output.
+wrrle.c		Utah RLE file output.
+wrtarga.c	Targa file output.
+
+
+RDJPGCOM/WRJPGCOM
+=================
+
+C source code files:
+
+rdjpgcom.c	Stand-alone rdjpgcom application.
+wrjpgcom.c	Stand-alone wrjpgcom application.
+
+These programs do not depend on the IJG library.  They do use
+jconfig.h and jinclude.h, only to improve portability.
+
+

+
+README		Master documentation file.

+TurboJPEG/OSS Java Wrapper
+==========================
+
+TurboJPEG/OSS can optionally be built with a Java Native Interface wrapper,
+which allows the TurboJPEG/OSS dynamic library to be loaded and used directly
+from Java applications.  The Java front end for this is defined in several
+classes located under org/libjpegturbo/turbojpeg.  The source code for these
+Java classes is licensed under a BSD-style license, so the files can be
+incorporated directly into both open source and proprietary projects without
+restriction.  A Java archive (JAR) file containing these classes is also
+shipped with the "official" distribution packages of libjpeg-turbo.
+
+TJExample.java, which should also be located in the same directory as this
+README file, demonstrates how to use the TurboJPEG/OSS Java front end to
+compress and decompress JPEG images in memory.
+
+
+Performance Pitfalls
+--------------------
+
+The TurboJPEG Java front end defines several convenience methods that can
+allocate image buffers or instantiate classes to hold the result of compress,
+decompress, or transform operations.  However, if you use these methods, then
+be mindful of the amount of new data you are creating on the heap.  It may be
+necessary to manually invoke the garbage collector to prevent heap exhaustion
+or to prevent performance degradation.  Background garbage collection can kill
+performance, particularly in a multi-threaded environment (Java pauses all
+threads when the GC runs.)
+
+The Java front end always gives you the option of pre-allocating your own
+source and destination buffers, which allows you to re-use these buffers for
+compressing/decompressing multiple images.  If the image sequence you are
+compressing or decompressing consists of images of the same size, then
+pre-allocating the buffers is recommended.
+
+
+Note for OS X users
+-------------------
+
+/usr/lib, the directory under which libturbojpeg.dylib is installed on Mac
+systems, is not part of the normal Java library path.  Thus, when running a
+Java application that uses TurboJPEG/OSS on Mac systems, you will need to pass
+an argument of -Djava.library.path=/usr/lib to java.
+
+
+Note for Solaris users
+----------------------
+
+/opt/libjpeg-turbo/lib, the directory under which libturbojpeg.so is installed
+on Solaris systems, is not part of the normal Java library path.  Thus, when
+running a Java application that uses TurboJPEG/OSS on Solaris systems, you will
+need to pass an argument of -Djava.library.path=/opt/libjpeg-turbo/lib to java.
+If using a 64-bit data model, then instead pass an argument of
+-Djava.library.path=/opt/libjpeg-turbo/lib/amd64 to use the 64-bit version of
+libturbojpeg.so.

+<H1>
+How This API Document Is Organized</H1>
+</CENTER>
+This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.<H3>
+Package</H3>
+<BLOCKQUOTE>
+
+<P>
+Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:<UL>
+<LI>Interfaces (italic)<LI>Classes<LI>Enums<LI>Exceptions<LI>Errors<LI>Annotation Types</UL>
+</BLOCKQUOTE>
+<H3>
+Class/Interface</H3>
+<BLOCKQUOTE>
+
+<P>
+Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:<UL>
+<LI>Class inheritance diagram<LI>Direct Subclasses<LI>All Known Subinterfaces<LI>All Known Implementing Classes<LI>Class/interface declaration<LI>Class/interface description
+<P>
+<LI>Nested Class Summary<LI>Field Summary<LI>Constructor Summary<LI>Method Summary
+<P>
+<LI>Field Detail<LI>Constructor Detail<LI>Method Detail</UL>
+Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</BLOCKQUOTE>
+</BLOCKQUOTE>
+<H3>
+Annotation Type</H3>
+<BLOCKQUOTE>
+
+<P>
+Each annotation type has its own separate page with the following sections:<UL>
+<LI>Annotation Type declaration<LI>Annotation Type description<LI>Required Element Summary<LI>Optional Element Summary<LI>Element Detail</UL>
+</BLOCKQUOTE>
+</BLOCKQUOTE>
+<H3>
+Enum</H3>
+<BLOCKQUOTE>
+
+<P>
+Each enum has its own separate page with the following sections:<UL>
+<LI>Enum declaration<LI>Enum description<LI>Enum Constant Summary<LI>Enum Constant Detail</UL>
+</BLOCKQUOTE>
+<H3>
+Tree (Class Hierarchy)</H3>
+<BLOCKQUOTE>
+There is a <A HREF="overview-tree.html">Class Hierarchy</A> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.<UL>
+<LI>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.<LI>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</UL>
+</BLOCKQUOTE>
+<H3>
+Deprecated API</H3>
+<BLOCKQUOTE>
+The <A HREF="deprecated-list.html">Deprecated API</A> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</BLOCKQUOTE>
+<H3>
+Index</H3>
+<BLOCKQUOTE>
+The <A HREF="index-all.html">Index</A> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</BLOCKQUOTE>
+<H3>
+Prev/Next</H3>
+These links take you to the next or previous class, interface, package, or related page.<H3>
+Frames/No Frames</H3>
+These links show and hide the HTML frames.  All pages are available with or without frames.
+<P>
+<H3>
+Serialized Form</H3>
+Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.
+<P>
+<H3>
+Constant Field Values</H3>
+The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.
+<P>
+<FONT SIZE="-1">

+This help file applies to API documentation generated using the standard doclet.</EM>
