+
+-- 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.

+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.

 OVERVIEW
 ========
 
-This package 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.
+
+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.

-(Support for progressive mode may be offered in a future release.)

 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 of the
-library if not required for a particular application.  We have also included

 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

-RELATED SOFTWARE
-================
-
-Numerous viewing and image manipulation programs now support JPEG.  (Quite a
-few of them use this library to do so.)  The JPEG FAQ described above lists
-some of the more popular free and shareware viewers, and tells where to
-obtain them on Internet.
-
-If you are on a Unix machine, we highly recommend Jef Poskanzer's free
-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 obtain this package by FTP from ftp.x.org

-a newer update of this package called NETPBM, available from
-wuarchive.wustl.edu under directory /graphics/graphics/packages/NetPBM/.
-Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software
-is; you are likely to have difficulty making it work on any non-Unix machine.
-
-A different free JPEG implementation, written by the PVRG group at Stanford,
-is available from havefun.stanford.edu in directory pub/jpeg.  This program
-is designed for research and experimentation rather than production use;
-it is slower, harder to use, and less portable than the IJG code, but it
-implements a larger subset of the JPEG standard.  In particular, it supports
-lossless JPEG.
-
-
 FILE FORMAT WARS
 ================
 
-Some JPEG programs produce files that are not compatible with our library.
-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 it has
-become the de facto standard.  JFIF is a minimal or "low end" representation.
-Work is also going forward to incorporate JPEG compression into the TIFF
-standard, for use in "high end" applications that need to record a lot of
-additional data about an image.  We intend to support TIFF 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/JPEG!
+The ISO JPEG standards committee actually promotes different formats like
+"JPEG 2000" or "JPEG XR", which are incompatible with original DCT-based
+JPEG.  IJG therefore does not support these formats (see REFERENCES).  Indeed,
+one of the original reasons for developing this free software was to help
+force convergence on common, interoperable format standards for JPEG files.
+Don't use an incompatible file format!
+(In any case, our decoder will remain capable of reading existing JPEG
+image files indefinitely.)

+*******************************************************************************
+**     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.

-.TH ANSI2KNR 1 "31 December 1990" 
-.SH NAME
-ansi2knr \- convert ANSI C to Kernighan & Ritchie C
-.SH SYNOPSIS
-.I ansi2knr
-input_file output_file
-.SH DESCRIPTION
-If no output_file is supplied, output goes to stdout.
-.br
-There are no error messages.
-.sp
-.I ansi2knr
-recognizes functions by seeing a non-keyword identifier at the left margin, followed by a left parenthesis, with a right parenthesis as the last character on the line.  It will recognize a multi-line header if the last character on each line but the last is a left parenthesis or comma.  These algorithms ignore whitespace and comments, except that the function name must be the first thing on the line.
-.sp
-The following constructs will confuse it:
-.br
-     - Any other construct that starts at the left margin and follows the above syntax (such as a macro or function call).
-.br
-     - Macros that tinker with the syntax of the function header.

-		    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

-EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED

-ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF GHOSTSCRIPT IS WITH

-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.

+
+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.

+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
+"wizard" switches below.)
+.PP
+JPEG files generated with separate luminance and chrominance quality are fully
+compliant with standard JPEG decoders.
+.PP
+.BR CAUTION:
+For this setting to be useful, be sure to pass an argument of \fB-sample 1x1\fR
+to \fBcjpeg\fR to disable chrominance subsampling.  Otherwise, the default
+subsampling level (2x2, AKA "4:2:0") will be used.
+.PP
+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

+so you'll want to keep around a regular 8-bit compilation as well.
+(Run-time selection of data depth, to allow a single copy that does both,
+is possible but would probably slow things down considerably; it's very low
+on our to-do list.)
+
+The PPM reader (rdppm.c) can read 12-bit data from either text-format or
+binary-format PPM and PGM files.  Binary-format PPM/PGM files which have a
+maxval greater than 255 are assumed to use 2 bytes per sample, MSB first
+(big-endian order).  As of early 1995, 2-byte binary format is not
+officially supported by the PBMPLUS library, but it is expected that a
+future release of PBMPLUS will support it.  Note that the PPM reader will
+read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming
+data is automatically rescaled to either maxval=255 or maxval=4095 as
+appropriate for the cjpeg bit depth.
+
+The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM
+format, maxval 4095, when compiled with BITS_IN_JSAMPLE=12.  Since this
+format is not yet widely supported, you can disable it by compiling wrppm.c
+with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a
+standard 1-byte/sample PPM or PGM file.  (Yes, this means still another copy
+of djpeg to keep around.  But hopefully you won't need it for very long.
+Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.)
+
+Of course, if you are working with 12-bit data, you probably have it stored
+in some other, nonstandard format.  In that case you'll probably want to
+write your own I/O modules to read and write your format.
+
+Note that a 12-bit version of cjpeg always runs in "-optimize" mode, in
+order to generate valid Huffman tables.  This is necessary because our
+default Huffman tables only cover 8-bit data.

+Microsoft Windows (all versions), generic comments:
+
+Some Windows system include files define typedef boolean as "unsigned char".
+The IJG code also defines typedef boolean, but we make it "int" by default.
+This doesn't affect the IJG programs because we don't import those Windows
+include files.  But if you use the JPEG library in your own program, and some
+of your program's files import one definition of boolean while some import the
+other, you can get all sorts of mysterious problems.  A good preventive step
+is to make the IJG library use "unsigned char" for boolean.  To do that,
+add something like this to your jconfig.h file:
+	/* Define "boolean" as unsigned char, not int, per Windows custom */
+	#ifndef __RPCNDR_H__	/* don't conflict if rpcndr.h already read */
+	typedef unsigned char boolean;
+	#endif
+	#define HAVE_BOOLEAN	/* prevent jmorecfg.h from redefining it */
+(This is already in jconfig.vc, by the way.)
+
+windef.h contains the declarations
+	#define far
+	#define FAR far
+Since jmorecfg.h tries to define FAR as empty, you may get a compiler
+warning if you include both jpeglib.h and windef.h (which windows.h
+includes).  To suppress the warning, you can put "#ifndef FAR"/"#endif"
+around the line "#define FAR" in jmorecfg.h.
+(Something like this is already in jmorecfg.h, by the way.)
+
+When using the library in a Windows application, you will almost certainly
+want to modify or replace the error handler module jerror.c, since our
+default error handler does a couple of inappropriate things:
+  1. it tries to write error and warning messages on stderr;
+  2. in event of a fatal error, it exits by calling exit().
+
+A simple stopgap solution for problem 1 is to replace the line
+	fprintf(stderr, "%s\n", buffer);
+(in output_message in jerror.c) with
+	MessageBox(GetActiveWindow(),buffer,"JPEG Error",MB_OK|MB_ICONERROR);
+It's highly recommended that you at least do that much, since otherwise
+error messages will disappear into nowhere.  (Beginning with IJG v6b, this
+code is already present in jerror.c; just define USE_WINDOWS_MESSAGEBOX in
+jconfig.h to enable it.)
+
+The proper solution for problem 2 is to return control to your calling
+application after a library error.  This can be done with the setjmp/longjmp
+technique discussed in libjpeg.txt and illustrated in example.c.  (NOTE:
+some older Windows C compilers provide versions of setjmp/longjmp that
+don't actually work under Windows.  You may need to use the Windows system
+functions Catch and Throw instead.)
+
+The recommended memory manager under Windows is jmemnobs.c; in other words,
+let Windows do any virtual memory management needed.  You should NOT use
+jmemdos.c nor jmemdosa.asm under Windows.
+
+For Windows 3.1, we recommend compiling in medium or large memory model;
+for newer Windows versions, use a 32-bit flat memory model.  (See the MS-DOS
+sections above for more info about memory models.)  In the 16-bit memory
+models only, you'll need to put
+	#define MAX_ALLOC_CHUNK 65520L	/* Maximum request to malloc() */
+into jconfig.h to limit allocation chunks to 64Kb.  (Without that, you'd
+have to use huge memory model, which slows things down unnecessarily.)
+jmemnobs.c works without modification in large or flat memory models, but to
+use medium model, you need to modify its jpeg_get_large and jpeg_free_large
+routines to allocate far memory.  In any case, you might like to replace
+its calls to malloc and free with direct calls on Windows memory allocation
+functions.
+
+You may also want to modify jdatasrc.c and jdatadst.c to use Windows file
+operations rather than fread/fwrite.  This is only necessary if your C
+compiler doesn't provide a competent implementation of C stdio functions.
+
+You might want to tweak the RGB_xxx macros in jmorecfg.h so that the library
+will accept or deliver color pixels in BGR sample order, not RGB; BGR order
+is usually more convenient under Windows.  Note that this change will break
+the sample applications cjpeg/djpeg, but the library itself works fine.
+
+
+Many people want to convert the IJG library into a DLL.  This is reasonably
+straightforward, but watch out for the following:
+
+  1. Don't try to compile as a DLL in small or medium memory model; use
+large model, or even better, 32-bit flat model.  Many places in the IJG code
+assume the address of a local variable is an ordinary (not FAR) pointer;
+that isn't true in a medium-model DLL.
+
+  2. Microsoft C cannot pass file pointers between applications and DLLs.
+(See Microsoft Knowledge Base, PSS ID Number Q50336.)  So jdatasrc.c and
+jdatadst.c don't work if you open a file in your application and then pass
+the pointer to the DLL.  One workaround is to make jdatasrc.c/jdatadst.c
+part of your main application rather than part of the DLL.
+
+  3. You'll probably need to modify the macros GLOBAL() and EXTERN() to
+attach suitable linkage keywords to the exported routine names.  Similarly,
+you'll want to modify METHODDEF() and JMETHOD() to ensure function pointers
+are declared in a way that lets application routines be called back through
+the function pointers.  These macros are in jmorecfg.h.  Typical definitions
+for a 16-bit DLL are:
+	#define GLOBAL(type)		type _far _pascal _loadds _export
+	#define EXTERN(type)		extern type _far _pascal _loadds
+	#define METHODDEF(type)		static type _far _pascal
+	#define JMETHOD(type,methodname,arglist)  \
+		type (_far _pascal *methodname) arglist
+For a 32-bit DLL you may want something like
+	#define GLOBAL(type)		__declspec(dllexport) type
+	#define EXTERN(type)		extern __declspec(dllexport) type
+Although not all the GLOBAL routines are actually intended to be called by
+the application, the performance cost of making them all DLL entry points is
+negligible.
+
+The unmodified IJG library presents a very C-specific application interface,
+so the resulting DLL is only usable from C or C++ applications.  There has
+been some talk of writing wrapper code that would present a simpler interface
+usable from other languages, such as Visual Basic.  This is on our to-do list
+but hasn't been very high priority --- any volunteers out there?
+
+
+Microsoft Windows, Borland C:
+
+The provided jconfig.bcc should work OK in a 32-bit Windows environment,
+but you'll need to tweak it in a 16-bit environment (you'd need to define
+NEED_FAR_POINTERS and MAX_ALLOC_CHUNK).  Beware that makefile.bcc will need
+alteration if you want to use it for Windows --- in particular, you should
+use jmemnobs.c not jmemdos.c under Windows.
+
+Borland C++ 4.5 fails with an internal compiler error when trying to compile
+jdmerge.c in 32-bit mode.  If enough people complain, perhaps Borland will fix
+it.  In the meantime, the simplest known workaround is to add a redundant
+definition of the variable range_limit in h2v1_merged_upsample(), at the head
+of the block that handles odd image width (about line 268 in v6 jdmerge.c):
+  /* If image width is odd, do the last output column separately */
+  if (cinfo->output_width & 1) {
+    register JSAMPLE * range_limit = cinfo->sample_range_limit; /* ADD THIS */
+    cb = GETJSAMPLE(*inptr1);
+Pretty bizarre, especially since the very similar routine h2v2_merged_upsample
+doesn't trigger the bug.
+Recent reports suggest that this bug does not occur with "bcc32a" (the
+Pentium-optimized version of the compiler).
+
+Another report from a user of Borland C 4.5 was that incorrect code (leading
+to a color shift in processed images) was produced if any of the following
+optimization switch combinations were used: 
+	-Ot -Og
+	-Ot -Op
+	-Ot -Om
+So try backing off on optimization if you see such a problem.  (Are there

+IJG JPEG 7 adds extern "C" to jpeglib.h.  This avoids the need to put

+You can also force VC++ to treat the library as C++ code by renaming

+In this case you also need to define the symbol DONT_USE_EXTERN_C in

+We include makefiles that should work as project files in DevStudio 6.0 or

+as Win32 console applications.  (Even if you only want the library, we
+recommend building the applications so that you can run the self-test.)

+To use:

+   (Note that the renaming is critical!)
+2. Open the workspace file jpeg.dsw, build the library project.
+   (If you are using DevStudio more recent than 6.0, you'll probably
+   get a message saying that the project files are being updated.)
+3. Open the workspace file apps.dsw, build the application projects.
+4. To perform the self-test, execute the command line
+	NMAKE /f makefile.vc  test-build
+5. Move the application .exe files from `app`\Release to an
+   appropriate location on your path.
+
+
+Microsoft Windows, Microsoft Visual C++ 2010 Developer Studio (v10):
+
+We include makefiles that should work as project files in Visual Studio
+2010 or later.  There is a library makefile that builds the IJG library
+as a static Win32 library, and application makefiles that build the sample
+applications as Win32 console applications.  (Even if you only want the
+library, we recommend building the applications so that you can run the
+self-test.)
+
+To use:
+1. Open the command prompt, change to the main directory and execute the
+   command line
+	NMAKE /f makefile.vc  setup-v10
+   This will move jconfig.vc to jconfig.h and makefiles to project files.
+   (Note that the renaming is critical!)
+2. Open the solution file jpeg.sln, build the library project.
+   (If you are using Visual Studio more recent than 2010 (v10), you'll
+   probably get a message saying that the project files are being updated.)
+3. Open the solution file apps.sln, build the application projects.
+4. To perform the self-test, execute the command line
+	NMAKE /f makefile.vc  test-build
+5. Move the application .exe files from `app`\Release to an
+   appropriate location on your path.
+
+Note:
+There seems to be an optimization bug in the compiler which causes the
+self-test to fail with the color quantization option.
+We have disabled optimization for the file jquant2.c in the library
+project file which causes the self-test to pass properly.
+
+
+OS/2, Borland C++:
+
+Watch out for optimization bugs in older Borland compilers; you may need
+to back off the optimization switch settings.  See the comments in
+makefile.bcc.

+On some SGI systems, you may need to set "AR2= ar -ts" in the Makefile.
+If you are using configure, you can do this by saying
 	./configure RANLIB='ar -ts'
+This change is not needed on all SGIs.  Use it only if the make fails at the
+stage of linking the completed programs.
+
+On the MIPS R4000 architecture (Indy, etc.), the compiler option "-mips2"
+reportedly speeds up the float DCT method substantially, enough to make it
+faster than the default int method (but still slower than the fast int
+method).  If you use -mips2, you may want to alter the default DCT method to
+be float.  To do this, put "#define JDCT_DEFAULT JDCT_FLOAT" in jconfig.h.

+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>
