+Contributing to libjpeg-turbo
+=============================
+
+libjpeg-turbo is a stable and mature product with a worldwide reach, it is an
+ISO/ITU-T reference implementation of the JPEG standard, and its maintainer
+does not earn a salary for maintaining it.  Thus, not every code contribution
+can or will be accepted into the libjpeg-turbo code base.  In order to maximize
+the chances that a code contribution is acceptable, please adhere to the
+following guidelines:
+
+1. If the code contribution is a bug fix, then please ensure that enough
+information is provided so that the maintainer can readily reproduce and
+document the bug.  That information should include:
+    - A clear and concise description of the bug
+    - The steps and (if applicable) images necessary to reproduce the bug
+    - The compilers, operating systems, and CPUs with which the bug was
+      observed
+    - The versions of libjpeg-turbo with which the bug was observed
+    - If the bug is a regression, the specific commit that introduced the bug
+      (use `git bisect` to determine this)
+
+2. If the code contribution will implement a major new feature, then please
+contact the project maintainer (through a
+[GitHub issue](https://github.com/libjpeg-turbo/libjpeg-turbo/issues/new),
+[direct e-mail](https://libjpeg-turbo.org/About/Contact), or the
+[libjpeg-turbo-devel mailing list](https://libjpeg-turbo.org/About/MailingLists))
+prior to implementing the feature.  In general, major new features that are
+potentially disruptive to the quality of libjpeg-turbo are unlikely to be
+accepted unless:
+    - The new feature is within the existing scope of libjpeg-turbo.
+    - The new feature has been thoroughly regression tested and benchmarked on
+      all of the supported platforms that are potentially affected by it.
+    - The new feature has been documented clearly and concisely in the change
+      log and (if applicable) the libjpeg and TurboJPEG API documentation and
+      man pages.
+    - The code implementing the new feature is formatted consistently with the
+      rest of the libjpeg-turbo code base (use
+      [checkstyle](https://github.com/libjpeg-turbo/checkstyle) to validate
+      this.)
+    - The new feature does not introduce new members into the exposed libjpeg
+      API structures (doing so would break backward ABI compatibility.)
+    - The new feature does not alter existing libjpeg-turbo usage or
+      development workflows.
+    - The code implementing the new feature is elegant, easily maintainable,
+      and causes the least possible amount of disruption to the libjpeg-turbo
+      code base.
+    - The new feature is based on the dev branch of the libjpeg-turbo
+      repository.
+
+    ... OR ...
+
+    - Your organization is prepared to pay for the labor necessary to ensure
+      all of the above.  Even the most well-written patches can still require
+      a significant amount of labor to clean up, test, and integrate.  (See
+      above RE: the maintainer not earning a salary.)
+
+    Specific types of features that *will not* be accepted:
+
+    - Features that extend the scope of libjpeg-turbo to support image formats
+      other than DCT-based JPEG and JFIF
+    - Features that extend the scope of libjpeg-turbo to support image
+      processing algorithms that are not necessary for JPEG compression or
+      decompression
+    - Extensions to the JPEG format that have not been approved by the
+      appropriate standards bodies
+    - Non-trivial performance enhancements that have less than a 5% overall
+      impact on performance
+
+3. If the code contribution is a build system enhancement, then please be
+prepared to justify the enhancement.  In general, build system enhancements
+are unlikely to be accepted unless:
+    - The enhancement is potentially beneficial to a significant number of
+      upstream libjpeg-turbo users/developers.  (If the enhancement is only
+      beneficial to a downstream project, then it does not belong here.)
+    - The enhancement has been tested with the following CMake versions:
+        - The earliest version of CMake that libjpeg-turbo currently supports
+          (refer to CMakeLists.txt)
+        - The most recent major version of CMake
+        - (if applicable) The earliest version of CMake with which the
+          enhancement can be used
+    - The enhancement has been tested on all of the major platforms (Mac,
+      Linux, Windows/Visual C++, Windows/MinGW) that are potentially affected
+      by it.
+    - The enhancement does not introduce new build system requirements or CMake
+      variables unless absolutely necessary.
+    - The enhancement does not alter existing libjpeg-turbo development
+      workflows.
+
+    Specific types of build system enhancements that *will not* be accepted:
+
+    - Enhancements that allow libjpeg-turbo to be built from a subdirectory
+      of a downstream repository.  These enhancements are not maintainable in
+      the upstream libjpeg-turbo build system.  Use the CMake
+      `ExternalProject_Add()` function instead.
+    - Enhancements that introduce new (non-CMake-based) build systems

+Building libjpeg-turbo
+======================
+
+
+Build Requirements
+------------------
+
+
+### All Systems
+
+- [CMake](http://www.cmake.org) v2.8.12 or later
+
+- [NASM](http://www.nasm.us) or [YASM](http://yasm.tortall.net)
+  (if building x86 or x86-64 SIMD extensions)
+  * If using NASM, 2.10 or later is required.
+  * If using NASM, 2.10 or later (except 2.11.08) is required for an x86-64 Mac
+    build (2.11.08 does not work properly with libjpeg-turbo's x86-64 SIMD code
+    when building macho64 objects.)  NASM or YASM can be obtained from
+    [MacPorts](http://www.macports.org/) or [Homebrew](http://brew.sh/).
+  * If using YASM, 1.2.0 or later is required.
+     - NOTE: Currently, if it is desirable to hide the SIMD function symbols in
+       Mac executables or shared libraries that statically link with
+       libjpeg-turbo, then YASM must be used when building libjpeg-turbo.
+  * If building on Windows, **nasm.exe**/**yasm.exe** should be in your `PATH`.
+
+  The binary RPMs released by the NASM project do not work on older Linux
+  systems, such as Red Hat Enterprise Linux 5.  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.
+
+
+### Un*x Platforms (including Linux, Mac, FreeBSD, Solaris, and Cygwin)
+
+- GCC v4.1 (or later) or Clang recommended for best performance
+
+- If building the TurboJPEG Java wrapper, JDK or OpenJDK 1.5 or later is
+  required.  Most modern Linux distributions, as well as Solaris 10 and later,
+  include JDK or OpenJDK.  On OS X 10.5 and 10.6, it will be necessary to
+  install the Java Developer Package, which can be downloaded from
+  <http://developer.apple.com/downloads> (Apple ID required.)  For other
+  systems, you can obtain the Oracle Java Development Kit from
+  <http://www.oracle.com/technetwork/java/javase/downloads>.
+
+  * If using JDK 11 or later, CMake 3.10.x or later must also be used.
+
+### Windows
+
+- 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.
+
+  * You can also use Microsoft Visual Studio Express/Community Edition, which
+    is a free download.  (NOTE: versions prior to 2012 can only be used to
+    build 32-bit code.)
+  * 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.
+
+   ... OR ...
+
+- MinGW
+
+  [MSYS2](http://msys2.github.io/) or [tdm-gcc](http://tdm-gcc.tdragon.net/)
+  recommended if building on a Windows machine.  Both distributions install a
+  Start Menu link that can be used to launch a command prompt with the
+  appropriate compiler paths automatically set.
+
+- If building the TurboJPEG Java wrapper, JDK 1.5 or later is required.  This
+  can be downloaded from
+  <http://www.oracle.com/technetwork/java/javase/downloads>.
+
+  * If using JDK 11 or later, CMake 3.10.x or later must also be used.
+
+
+Out-of-Tree Builds
+------------------
+
+Binary objects, libraries, and executables are generated in the directory from
+which CMake is 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.
+
+
+Build Procedure
+---------------
+
+NOTE: The build procedures below assume that CMake is invoked from the command
+line, but all of these procedures can be adapted to the CMake GUI as
+well.
+
+
+### Un*x
+
+The following procedure will build libjpeg-turbo on Unix and Unix-like systems.
+(On Solaris, this generates a 32-bit build.  See "Build Recipes" below for
+64-bit build instructions.)
+
+    cd {build_directory}
+    cmake -G"Unix Makefiles" [additional CMake flags] {source_directory}
+    make
+
+This will generate the following files under *{build_directory}*:
+
+**libjpeg.a**<br>
+Static link library for the libjpeg API
+
+**libjpeg.so.{version}** (Linux, Unix)<br>
+**libjpeg.{version}.dylib** (Mac)<br>
+**cygjpeg-{version}.dll** (Cygwin)<br>
+Shared library for the libjpeg API
+
+By default, *{version}* is 62.2.0, 7.2.0, or 8.1.2, depending on whether
+libjpeg v6b (default), v7, or v8 emulation is enabled.  If using Cygwin,
+*{version}* is 62, 7, or 8.
+
+**libjpeg.so** (Linux, Unix)<br>
+**libjpeg.dylib** (Mac)<br>
+Development symlink for the libjpeg API
+
+**libjpeg.dll.a** (Cygwin)<br>
+Import library for the libjpeg API
+
+**libturbojpeg.a**<br>
+Static link library for the TurboJPEG API
+
+**libturbojpeg.so.0.2.0** (Linux, Unix)<br>
+**libturbojpeg.0.2.0.dylib** (Mac)<br>
+**cygturbojpeg-0.dll** (Cygwin)<br>
+Shared library for the TurboJPEG API
+
+**libturbojpeg.so** (Linux, Unix)<br>
+**libturbojpeg.dylib** (Mac)<br>
+Development symlink for the TurboJPEG API
+
+**libturbojpeg.dll.a** (Cygwin)<br>
+Import library for the TurboJPEG API
+
+
+### Visual C++ (Command Line)
+
+    cd {build_directory}
+    cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release [additional CMake flags] {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**<br>
+Static link library for the libjpeg API
+
+**jpeg{version}.dll**<br>
+DLL for the libjpeg API
+
+**jpeg.lib**<br>
+Import library for the libjpeg API
+
+**turbojpeg-static.lib**<br>
+Static link library for the TurboJPEG API
+
+**turbojpeg.dll**<br>
+DLL for the TurboJPEG API
+
+**turbojpeg.lib**<br>
+Import library for the TurboJPEG API
+
+*{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 10" [additional CMake flags] {source_directory}
+
+NOTE: Add "Win64" to the generator name (for example, "Visual Studio 10 Win64")
+to build a 64-bit version of libjpeg-turbo.  A separate build directory must be
+used for 32-bit and 64-bit builds.
+
+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**<br>
+Static link library for the libjpeg API
+
+**{configuration}/jpeg{version}.dll**<br>
+DLL for the libjpeg API
+
+**{configuration}/jpeg.lib**<br>
+Import library for the libjpeg API
+
+**{configuration}/turbojpeg-static.lib**<br>
+Static link library for the TurboJPEG API
+
+**{configuration}/turbojpeg.dll**<br>
+DLL for the TurboJPEG API
+
+**{configuration}/turbojpeg.lib**<br>
+Import library for the TurboJPEG API
+
+*{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
+
+NOTE: This assumes that you are building on a Windows machine using the MSYS
+environment.  If you are cross-compiling on a Un*x platform (including Mac and
+Cygwin), then see "Build Recipes" below.
+
+    cd {build_directory}
+    cmake -G"MSYS Makefiles" [additional CMake flags] {source_directory}
+    make
+
+This will generate the following files under *{build_directory}*:
+
+**libjpeg.a**<br>
+Static link library for the libjpeg API
+
+**libjpeg-{version}.dll**<br>
+DLL for the libjpeg API
+
+**libjpeg.dll.a**<br>
+Import library for the libjpeg API
+
+**libturbojpeg.a**<br>
+Static link library for the TurboJPEG API
+
+**libturbojpeg.dll**<br>
+DLL for the TurboJPEG API
+
+**libturbojpeg.dll.a**<br>
+Import library for the TurboJPEG API
+
+*{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 line to build a version of libjpeg-turbo that is
+API/ABI-compatible with libjpeg v8.  See [README.md](README.md) for more
+information about libjpeg v7 and v8 emulation.
+
+
+### In-Memory Source/Destination Managers
+
+When using libjpeg v6b or v7 API/ABI emulation, add `-DWITH_MEM_SRCDST=0` to
+the CMake command line to build a version of libjpeg-turbo that lacks the
+`jpeg_mem_src()` and `jpeg_mem_dest()` functions.  These functions were not
+part of the original libjpeg v6b and v7 APIs, so removing them ensures strict
+conformance with those APIs.  See [README.md](README.md) for more information.
+
+
+### 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 Java Wrapper
+
+Add `-DWITH_JAVA=1` to the CMake command line to incorporate an optional Java
+Native Interface (JNI) wrapper into the TurboJPEG shared library and build the
+Java front-end classes to support it.  This allows the TurboJPEG shared library
+to be used directly from Java applications.  See [java/README](java/README) for
+more details.
+
+If Java is not in your `PATH`, or if you wish to use an alternate JDK to
+build/test libjpeg-turbo, then (prior to running CMake) set the `JAVA_HOME`
+environment variable to the location of the JDK that you wish to use.  The
+`Java_JAVAC_EXECUTABLE`, `Java_JAVA_EXECUTABLE`, and `Java_JAR_EXECUTABLE`
+CMake variables can also be used to specify alternate commands or locations for
+javac, jar, and java (respectively.)  You can also set the
+`CMAKE_JAVA_COMPILE_FLAGS` CMake variable or the `JAVAFLAGS` environment
+variable to specify arguments that should be passed to the Java compiler when
+building the TurboJPEG classes, and the `JAVAARGS` CMake variable to specify
+arguments that should be passed to the JRE when running the TurboJPEG Java unit
+tests.

+
+Build Recipes
+-------------
+
+
+### 32-bit Build on 64-bit Linux/Unix/Mac
+
+Use export/setenv to set the following environment variables before running
+CMake:
+
+    CFLAGS=-m32
+    LDFLAGS=-m32
+
+
+### 64-bit Build on Solaris
+
+Use export/setenv to set the following environment variables before running
+CMake:
+
+    CFLAGS=-m64
+    LDFLAGS=-m64
+
+
+### Other Compilers
+
+On Un*x systems, prior to running CMake, you can set the `CC` environment
+variable to the command used to invoke the C compiler.
+
+
+### 32-bit MinGW Build on Un*x (including Mac and Cygwin)
+
+Create a file called **toolchain.cmake** under *{build_directory}*, with the

+    set(CMAKE_C_COMPILER {mingw_binary_path}/i686-w64-mingw32-gcc)
+    set(CMAKE_RC_COMPILER {mingw_binary_path}/i686-w64-mingw32-windres)
+
+*{mingw\_binary\_path}* is the directory under which the MinGW binaries are
+located (usually **/usr/bin**.)  Next, execute the following commands:
+
+    cd {build_directory}
+    cmake -G"Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=toolchain.cmake \

+
+Building libjpeg-turbo for iOS
+------------------------------
+
+iOS platforms, such as the iPhone and iPad, use ARM processors, and all
+currently supported models include NEON instructions.  Thus, they can take
+advantage of libjpeg-turbo's SIMD extensions to significantly accelerate JPEG
+compression/decompression.  This section describes how to build libjpeg-turbo
+for these platforms.
+
+
+### Additional build requirements
+
+- For configurations that require [gas-preprocessor.pl]
+  (https://raw.githubusercontent.com/libjpeg-turbo/gas-preprocessor/master/gas-preprocessor.pl),
+  it should be installed in your `PATH`.
+
+
+### ARMv7 (32-bit)

+
+Advanced CMake Options
+----------------------
+
+To list and configure other CMake options not specifically mentioned in this
+guide, run
+
+    ccmake {source_directory}
+
+or
+
+    cmake-gui {source_directory}
+
+from the build directory after initially configuring the build.  CCMake is a
+text-based interactive version of CMake, and CMake-GUI is a GUI version.  Both
+will display all variables that are relevant to the libjpeg-turbo build, their
+current values, and a help string describing what they do.
+
+
+Installing libjpeg-turbo
+========================
+
+You can use the build system to install libjpeg-turbo (as opposed to creating
+an installer package.)  To do this, run `make install` or `nmake install`
+(or build the "install" target in the Visual Studio IDE.)  Running
+`make uninstall` or `nmake uninstall` (or building the "uninstall" target in
+the Visual Studio IDE) will uninstall libjpeg-turbo.
+
+The `CMAKE_INSTALL_PREFIX` CMake variable can be modified in order to install
+libjpeg-turbo into a directory of your choosing.  If you don't specify
+`CMAKE_INSTALL_PREFIX`, then the default is:
+
+**c:\libjpeg-turbo**<br>
+Visual Studio 32-bit build
+
+**c:\libjpeg-turbo64**<br>
+Visual Studio 64-bit build
+
+**c:\libjpeg-turbo-gcc**<br>
+MinGW 32-bit build
+
+**c:\libjpeg-turbo-gcc64**<br>
+MinGW 64-bit build
+
+**/opt/libjpeg-turbo**<br>
+Un*x
+
+The default value of `CMAKE_INSTALL_PREFIX` causes the libjpeg-turbo files to
+be installed with a directory structure resembling that of the official
+libjpeg-turbo binary packages.  Changing the value of `CMAKE_INSTALL_PREFIX`
+(for instance, to **/usr/local**) causes the libjpeg-turbo files to be
+installed with a directory structure that conforms to GNU standards.
+
+The `CMAKE_INSTALL_BINDIR`, `CMAKE_INSTALL_DATAROOTDIR`,
+`CMAKE_INSTALL_DOCDIR`, `CMAKE_INSTALL_INCLUDEDIR`, `CMAKE_INSTALL_JAVADIR`,
+`CMAKE_INSTALL_LIBDIR`, and `CMAKE_INSTALL_MANDIR` CMake variables allow a
+finer degree of control over where specific files in the libjpeg-turbo
+distribution should be installed.  These directory variables can either be
+specified as absolute paths or as paths relative to `CMAKE_INSTALL_PREFIX` (for
+instance, setting `CMAKE_INSTALL_DOCDIR` to **doc** would cause the
+documentation to be installed in **${CMAKE\_INSTALL\_PREFIX}/doc**.)  If a
+directory variable contains the name of another directory variable in angle
+brackets, then its final value will depend on the final value of that other
+variable.  For instance, the default value of `CMAKE_INSTALL_MANDIR` is
+**\<CMAKE\_INSTALL\_DATAROOTDIR\>/man**.
+
+NOTE: If setting one of these directory variables to a relative path using the
+CMake command line, you must specify that the variable is of type `PATH`.
+For example:
+
+    cmake -G"{generator type}" -DCMAKE_INSTALL_LIBDIR:PATH=lib {source_directory}
+
+Otherwise, CMake will assume that the path is relative to the build directory
+rather than the install directory.
+
+
+Creating Distribution Packages
+==============================
+
+The following commands can be used to create various types of distribution
+packages:
+
+
+Linux
+-----
+
+    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.
+
+
+Mac
+---
+
+    make dmg
+
+Create Mac package/disk image.  This requires pkgbuild and productbuild, which
+are installed by default on OS X 10.7 and later and which can be obtained by
+installing Xcode 3.2.6 (with the "Unix Development" option) on OS X 10.6.
+Packages built in this manner can be installed on OS X 10.5 and later, but they
+must be built on OS X 10.6 or later.
+
+    make udmg
+
+This creates a Mac package/disk image that contains universal x86-64/i386/ARM
+binaries.  The following CMake variables control which architectures are
+included in the universal binaries.  Setting any of these variables to an empty
+string excludes that architecture from the package.
+
+* `OSX_32BIT_BUILD`: Directory containing an i386 (32-bit) Mac build of
+  libjpeg-turbo (default: *{source_directory}*/osxx86)
+* `IOS_ARMV7_BUILD`: Directory containing an ARMv7 (32-bit) iOS build of
+  libjpeg-turbo (default: *{source_directory}*/iosarmv7)
+* `IOS_ARMV7S_BUILD`: Directory containing an ARMv7s (32-bit) iOS build of
+  libjpeg-turbo (default: *{source_directory}*/iosarmv7s)
+* `IOS_ARMV8_BUILD`: Directory containing an ARMv8 (64-bit) iOS build of
+  libjpeg-turbo (default: *{source_directory}*/iosarmv8)
+
+You should first use CMake to configure i386, ARMv7, ARMv7s, and/or ARMv8
+sub-builds of libjpeg-turbo (see "Build Recipes" and "Building libjpeg-turbo
+for iOS" above) in build directories that match those specified in the
+aforementioned CMake variables.  Next, configure the primary build of
+libjpeg-turbo as an out-of-tree build, and build it.  Once the primary build
+has been built, run `make udmg` from the build directory.  The packaging system
+will build the sub-builds, use lipo to combine them into a single set of
+universal binaries, then package the universal binaries in the same manner as
+`make dmg`.
+
+
+Cygwin
+------
+
+    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" target.
+
+The installer package (libjpeg-turbo-*{version}*[-gcc|-vc][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` (Un*x) or
+`nmake test` (Windows command line) or by building the "RUN_TESTS" target
+(Visual Studio IDE), 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` (Un*x) or `nmake testclean` (Windows command line) or
+building the "testclean" target (Visual Studio IDE) will clean up the output
+images generated by the tests.
+
+On Un*x platforms, more extensive tests of the TurboJPEG 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 (including 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 API library.

-Build Requirements
-==================
-
--- autoconf 2.56 or later
--- automake 1.7 or later
--- libtool 1.4 or later
-   * If using Xcode 4.3 or later on OS X, autoconf and automake are no longer
-     provided.  The easiest way to obtain them is from MacPorts
-     (http://www.macports.org/).
-
--- 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
-   * Beginning with Xcode 4, Apple stopped distributing GCC and switched to
-     the LLVM compiler.  Xcode v4.0 through v4.6 provides a GCC front end
-     called LLVM-GCC.  Unfortunately, as of this writing, neither LLVM-GCC nor
-     the LLVM (clang) compiler produces optimal performance with libjpeg-turbo.
-     Building libjpeg-turbo with LLVM-GCC v4.2 results in a 10% performance
-     degradation when compressing using 64-bit code, relative to building
-     libjpeg-turbo with GCC v4.2.  Building libjpeg-turbo with LLVM (clang)
-     results in a 20% performance degradation when compressing using 64-bit
-     code, relative to building libjpeg-turbo with GCC v4.2.  If you are
-     running Snow Leopard or earlier, it is suggested that you continue to use
-     Xcode v3.2.6, which provides GCC v4.2.  If you are using Lion or later, it
-     is suggested that you install Apple GCC v4.2 through MacPorts.
-
--- If building the TurboJPEG 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://developer.apple.com/downloads (Apple ID required.)
-   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, 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 usually only necessary if
-building libjpeg-turbo from the SVN repository.
-
-This will generate the following files under .libs/
-
-  libjpeg.a
-      Static link library for the libjpeg API
-
-  libjpeg.so.{version} (Linux, Unix)
-  libjpeg.{version}.dylib (OS X)
-  cygjpeg-{version}.dll (Cygwin)
-      Shared library for the libjpeg API
-
-  By default, {version} is 62.1.0, 7.1.0, 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.so (Linux, Unix)
-  libjpeg.dylib (OS X)
-      Development symlink for the libjpeg API
-
-  libjpeg.dll.a (Cygwin)
-      Import library for the libjpeg API
-
-  libturbojpeg.a
-      Static link library for the TurboJPEG API
-
-  libturbojpeg.so.0.0.0 (Linux, Unix)
-  libturbojpeg.0.0.0.dylib (OS X)
-  cygturbojpeg-0.dll (Cygwin)
-      Shared library for the TurboJPEG API
-
-  libturbojpeg.so (Linux, Unix)
-  libturbojpeg.dylib (OS X)
-      Development symlink for the TurboJPEG API
-
-  libturbojpeg.dll.a (Cygwin)
-      Import library for the TurboJPEG API
-
-
-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.
-
-
-In-Memory Source/Destination Managers
--------------------------------------
-
-When using libjpeg v6b or v7 API/ABI emulation, add --without-mem-srcdst to the
-configure command line to build a version of libjpeg-turbo that lacks the
-jpeg_mem_src() and jpeg_mem_dest() functions.  These functions were not part of
-the original libjpeg v6b and v7 APIs, so removing them ensures strict
-conformance with those APIs.  See README-turbo.txt for more information.
-
-
-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 Java Wrapper
-----------------------
-Add --with-java to the configure command line to incorporate an optional Java
-Native Interface wrapper into the TurboJPEG shared library and build the Java
-front-end classes to support it.  This allows the TurboJPEG shared 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/lib32 (32-bit) or /opt/libjpeg-turbo/lib64
-(64-bit.)
-
-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 symlinks
-to force applications to use libjpeg-turbo instead of libjpeg.  See
-README-turbo.txt for more information.

-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://sourceforge.net/p/libjpeg-turbo/code/HEAD/tree/gas-preprocessor)
-  should be installed in your PATH.
-
-Set the following shell variables for simplicity:
-
-  Xcode 3.2.x / iOS 4.3 SDK:
-  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
-
-  Xcode 4.5.x / iOS 6.0 SDK:
-  IOS_PLATFORMDIR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform
-  IOS_SYSROOT=$IOS_PLATFORMDIR/Developer/SDKs/iPhoneOS6.0.sdk
-  IOS_GCC=$IOS_PLATFORMDIR/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2
-
-  Xcode 4.6.x / iOS 6.1 SDK:
-  IOS_PLATFORMDIR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform
-  IOS_SYSROOT=$IOS_PLATFORMDIR/Developer/SDKs/iPhoneOS6.1.sdk
-  IOS_GCC=$IOS_PLATFORMDIR/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2
-
-  Xcode 5.0.x / iOS 7.0 SDK:
-  IOS_PLATFORMDIR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform
-  IOS_SYSROOT=$IOS_PLATFORMDIR/Developer/SDKs/iPhoneOS7.0.sdk
-  IOS_GCC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
-
-  ARM v6 only (up to and including iPhone 3G):
-  [NOTE: Requires Xcode 4.4.x or earlier]
-  IOS_CFLAGS="-march=armv6 -mcpu=arm1176jzf-s -mfpu=vfp"
-
-  ARM v7 only (iPhone 3GS-4S, iPad 1st-3rd Generation):
-  GCC:
-  IOS_CFLAGS="-march=armv7 -mcpu=cortex-a8 -mtune=cortex-a8 -mfpu=neon"
-  Clang:
-  IOS_CFLAGS="-arch armv7 -no-integrated-as"
-
-  ARM v7s only (iPhone 5, iPad 4th Generation):
-  [NOTE: Requires Xcode 4.5 or later]
-  GCC
-  IOS_CFLAGS="-march=armv7s -mcpu=swift -mtune=swift -mfpu=neon"
-  Clang:
-  IOS_CFLAGS="-arch armv7s -no-integrated-as"
-
-Follow the procedure under "Building libjpeg-turbo" above, adding
-
-  --host arm-apple-darwin10 --enable-static --disable-shared \
-    CC="$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, v7, and/or v7s variants
-into a universal library.
-
-NOTE: If you are building libjpeg-turbo from the "official" project tarball,
-then it is highly likely that you will need to run 'autoreconf -fiv' in the
-source tree prior to building ARM v7 or v7s iOS binaries using the techniques
-described above.  Otherwise, you may get a libtool error such as "unable to
-infer tagged configuration."

-
-
-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 the libjpeg API
-  sharedlib/jpeg{version}.dll
-      DLL for the libjpeg API
-  sharedlib/jpeg.lib

-      Static link library for the TurboJPEG API
-  turbojpeg.dll
-      DLL for the TurboJPEG API
-  turbojpeg.lib
-      Import library for the TurboJPEG API
-
-{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 the libjpeg API
-  sharedlib/{configuration}/jpeg{version}.dll
-      DLL for the libjpeg API

-  {configuration}/turbojpeg.dll
-      DLL for the TurboJPEG API
-  {configuration}/turbojpeg.lib
-      Import library for the TurboJPEG API

-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.
-
-
-In-Memory Source/Destination Managers
--------------------------------------
-
-When using libjpeg v6b or v7 API/ABI emulation, add -DWITH_MEM_SRCDST=0 to the
-CMake command line to build a version of libjpeg-turbo that lacks the
-jpeg_mem_src() and jpeg_mem_dest() functions.  These functions were not part of
-the original libjpeg v6b and v7 APIs, so removing them ensures strict
-conformance with those APIs.  See README-turbo.txt for more information.
-
-
-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 Java Wrapper
-----------------------
-Add "-DWITH_JAVA=1" to the cmake command line to incorporate an optional Java
-Native Interface wrapper into the TurboJPEG shared library and build the Java
-front-end classes to support it.  This allows the TurboJPEG shared 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.

-*******************************************************************************
-**     Creating Release Packages
-*******************************************************************************
-
-The following commands can be used to create various types of release packages:
-
-
-Unix/Linux
-----------
-
-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.
-  Note that PackageMaker is not included in recent releases of Xcode, but it
-  can be obtained by downloading the "Auxiliary Tools for Xcode" package from
-  http://developer.apple.com/downloads.
-
-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}] \
-  [BUILDDIRARMV7S={ARM v7s 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, ARM v7, and/or ARM v7s 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,
-  the ARM v7s build under {source_directory}/iosarmv7s 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,
-  BUILDDIRARMV7, and/or BUILDDIRARMV7S variables 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 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 API library.

-1.3.1
-=====
-
-[1] On Un*x systems, 'make install' now installs the libjpeg-turbo libraries
-into /opt/libjpeg-turbo/lib32 by default on any 32-bit system, not just x86,
-and into /opt/libjpeg-turbo/lib64 by default on any 64-bit system, not just
-x86-64.  You can override this by overriding either the 'prefix' or 'libdir'
-configure variables.
-
-[2] The Windows installer now places a copy of the TurboJPEG DLLs in the same
-directory as the rest of the libjpeg-turbo binaries.  This was mainly done
-to support TurboVNC 1.3, which bundles the DLLs in its Windows installation.
-When using a 32-bit version of CMake on 64-bit Windows, it is impossible to
-access the c:\WINDOWS\system32 directory, which made it impossible for the
-TurboVNC build scripts to bundle the 64-bit TurboJPEG DLL.
-
-[3] Fixed a bug whereby attempting to encode a progressive JPEG with arithmetic
-entropy coding (by passing arguments of -progressive -arithmetic to cjpeg or
-jpegtran, for instance) would result in an error, "Requested feature was
-omitted at compile time".
-
-[4] Fixed a couple of issues whereby malformed JPEG images would cause
-libjpeg-turbo to use uninitialized memory during decompression.
-
-[5] Fixed an error ("Buffer passed to JPEG library is too small") that occurred
-when calling the TurboJPEG YUV encoding function with a very small (< 5x5)
-source image, and added a unit test to check for this error.
-
-[6] The Java classes should now build properly under Visual Studio 2010 and
-later.
-
-[7] Fixed an issue that prevented SRPMs generated using the in-tree packaging
-tools from being rebuilt on certain newer Linux distributions.
-
-[8] Numerous minor fixes to eliminate compilation and build/packaging system
-warnings, fix cosmetic issues, improve documentation clarity, and other general
-source cleanup.
-
-
-1.3.0
-=====
-
-[1] 'make test' now works properly on FreeBSD, and it no longer requires the
-md5sum executable to be present on other Un*x platforms.
-
-[2] Overhauled the packaging system:
--- To avoid conflict with vendor-supplied libjpeg-turbo packages, the
-official RPMs and DEBs for libjpeg-turbo have been renamed to
-"libjpeg-turbo-official".
--- The TurboJPEG libraries are now located under /opt/libjpeg-turbo in the
-official Linux and Mac packages, to avoid conflict with vendor-supplied
-packages and also to streamline the packaging system.
--- Release packages are now created with the directory structure defined
-by the configure variables "prefix", "bindir", "libdir", etc. (Un*x) or by the
-CMAKE_INSTALL_PREFIX variable (Windows.)  The exception is that the docs are
-always located under the system default documentation directory on Un*x and Mac
-systems, and on Windows, the TurboJPEG DLL is always located in the Windows
-system directory.
--- To avoid confusion, official libjpeg-turbo packages on Linux/Unix platforms
-(except for Mac) will always install the 32-bit libraries in
-/opt/libjpeg-turbo/lib32 and the 64-bit libraries in /opt/libjpeg-turbo/lib64.
--- Fixed an issue whereby, in some cases, the libjpeg-turbo executables on Un*x
-systems were not properly linking with the shared libraries installed by the
-same package.
--- Fixed an issue whereby building the "installer" target on Windows when
-WITH_JAVA=1 would fail if the TurboJPEG JAR had not been previously built.
--- Building the "install" target on Windows now installs files into the same
-places that the installer does.
-
-[3] Fixed a Huffman encoder bug that prevented I/O suspension from working
-properly.
-
-
-1.2.90 (1.3 beta1)
-==================
-
-[1] Added support for additional scaling factors (3/8, 5/8, 3/4, 7/8, 9/8, 5/4,
-11/8, 3/2, 13/8, 7/4, 15/8, and 2) when decompressing.  Note that the IDCT will
-not be SIMD-accelerated when using any of these new scaling factors.
-
-[2] The TurboJPEG dynamic library is now versioned.  It was not strictly
-necessary to do so, because TurboJPEG uses versioned symbols, and if a function
-changes in an ABI-incompatible way, that function is renamed and a legacy
-function is provided to maintain backward compatibility.  However, certain
-Linux distro maintainers have a policy against accepting any library that isn't
-versioned.
-
-[3] Extended the TurboJPEG Java API so that it can be used to compress a JPEG
-image from and decompress a JPEG image to an arbitrary position in a large
-image buffer.
-
-[4] The tjDecompressToYUV() function now supports the TJFLAG_FASTDCT flag.
-
-[5] The 32-bit supplementary package for amd64 Debian systems now provides
-symlinks in /usr/lib/i386-linux-gnu for the TurboJPEG libraries in /usr/lib32.
-This allows those libraries to be used on MultiArch-compatible systems (such as
-Ubuntu 11 and later) without setting the linker path.
-
-[6] The TurboJPEG Java wrapper should now find the JNI library on Mac systems
-without having to pass -Djava.library.path=/usr/lib to java.
-
-[7] TJBench has been ported to Java to provide a convenient way of validating
-the performance of the TurboJPEG Java API.  It can be run with
-'java -cp turbojpeg.jar TJBench'.
-
-[8] cjpeg can now be used to generate JPEG files with the RGB colorspace
-(feature ported from jpeg-8d.)
-
-[9] The width and height in the -crop argument passed to jpegtran can now be
-suffixed with "f" to indicate that, when the upper left corner of the cropping
-region is automatically moved to the nearest iMCU boundary, the bottom right
-corner should be moved by the same amount.  In other words, this feature causes
-jpegtran to strictly honor the specified width/height rather than the specified
-bottom right corner (feature ported from jpeg-8d.)
-
-[10] JPEG files using the RGB colorspace can now be decompressed into grayscale
-images (feature ported from jpeg-8d.)
-
-[11] Fixed a regression caused by 1.2.1[7] whereby the build would fail with
-multiple "Mismatch in operand sizes" errors when attempting to build the x86
-SIMD code with NASM 0.98.
-
-[12] The in-memory source/destination managers (jpeg_mem_src() and
-jpeg_mem_dest()) are now included by default when building libjpeg-turbo with
-libjpeg v6b or v7 emulation, so that programs can take advantage of these
-functions without requiring the use of the backward-incompatible libjpeg v8
-ABI.  The "age number" of the libjpeg-turbo library on Un*x systems has been
-incremented by 1 to reflect this.  You can disable this feature with a
-configure/CMake switch in order to retain strict API/ABI compatibility with the
-libjpeg v6b or v7 API/ABI (or with previous versions of libjpeg-turbo.)  See
-README-turbo.txt for more details.
-
-[13] Added ARM v7s architecture to libjpeg.a and libturbojpeg.a in the official
-libjpeg-turbo binary package for OS X, so that those libraries can be used to
-build applications that leverage the faster CPUs in the iPhone 5 and iPad 4.
-
-
-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 libjpeg-turbo binary package for OS X, 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 the TurboJPEG API
-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 the TurboJPEG wrapper 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 symlinks 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.
-
-
-0.0.93

+libjpeg-turbo Licenses
+======================
+
+libjpeg-turbo is covered by three compatible BSD-style open source licenses:
+
+- The IJG (Independent JPEG Group) License, which is listed in
+  [README.ijg](README.ijg)
+
+  This license applies to the libjpeg API library and associated programs
+  (any code inherited from libjpeg, and any modifications to that code.)
+
+- The Modified (3-clause) BSD License, which is listed below
+
+  This license covers the TurboJPEG API library and associated programs, as
+  well as the build system.
+
+- The [zlib License](https://opensource.org/licenses/Zlib)
+
+  This license is a subset of the other two, and it covers the libjpeg-turbo
+  SIMD extensions.
+
+
+Complying with the libjpeg-turbo Licenses
+=========================================
+
+This section provides a roll-up of the libjpeg-turbo licensing terms, to the
+best of our understanding.
+
+1.  If you are distributing a modified version of the libjpeg-turbo source,
+    then:
+
+    1.  You cannot alter or remove any existing copyright or license notices
+        from the source.
+
+        **Origin**
+        - Clause 1 of the IJG License
+        - Clause 1 of the Modified BSD License
+        - Clauses 1 and 3 of the zlib License
+
+    2.  You must add your own copyright notice to the header of each source
+        file you modified, so others can tell that you modified that file (if
+        there is not an existing copyright header in that file, then you can
+        simply add a notice stating that you modified the file.)
+
+        **Origin**
+        - Clause 1 of the IJG License
+        - Clause 2 of the zlib License
+
+    3.  You must include the IJG README file, and you must not alter any of the
+        copyright or license text in that file.
+
+        **Origin**
+        - Clause 1 of the IJG License
+
+2.  If you are distributing only libjpeg-turbo binaries without the source, or
+    if you are distributing an application that statically links with
+    libjpeg-turbo, then:
+
+    1.  Your product documentation must include a message stating:
+
+        This software is based in part on the work of the Independent JPEG
+        Group.
+
+        **Origin**
+        - Clause 2 of the IJG license
+
+    2.  If your binary distribution includes or uses the TurboJPEG API, then
+        your product documentation must include the text of the Modified BSD
+        License (see below.)
+
+        **Origin**
+        - Clause 2 of the Modified BSD License
+
+3.  You cannot use the name of the IJG or The libjpeg-turbo Project or the
+    contributors thereof in advertising, publicity, etc.
+
+    **Origin**
+    - IJG License
+    - Clause 3 of the Modified BSD License
+
+4.  The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be
+    free of defects, nor do we accept any liability for undesirable
+    consequences resulting from your use of the software.
+
+    **Origin**
+    - IJG License
+    - Modified BSD License
+    - zlib License
+
+
+The Modified (3-clause) BSD License

+CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
+ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGE.
+
+
+Why Three Licenses?
+===================
+
+The zlib License could have been used instead of the Modified (3-clause) BSD
+License, and since the IJG License effectively subsumes the distribution
+conditions of the zlib License, this would have effectively placed
+libjpeg-turbo binary distributions under the IJG License.  However, the IJG
+License specifically refers to the Independent JPEG Group and does not extend
+attribution and endorsement protections to other entities.  Thus, it was
+desirable to choose a license that granted us the same protections for new code
+that were granted to the IJG for code derived from their software.

-*******************************************************************************
-**     Background
-*******************************************************************************
-
-libjpeg-turbo is a JPEG image codec 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
-libjpeg, all else being equal.  On other types of systems, libjpeg-turbo can
-still outperform libjpeg by a significant amount, by virtue of its
-highly-optimized Huffman coding routines.  In many cases, the performance of
-libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
-
-libjpeg-turbo implements both the traditional libjpeg API as well as the less
-powerful but more straightforward TurboJPEG API.  libjpeg-turbo also features
-colorspace extensions that allow it to compress from/decompress to 32-bit and
-big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java
-interface.
-
-libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated
-derivative of libjpeg v6b developed by Miyasaka Masaru.  The TigerVNC and
-VirtualGL projects made numerous enhancements to the codec in 2009, and in
-early 2010, libjpeg-turbo spun off into an 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.  The libjpeg API implementation in 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.)
-
-There is no significant performance advantage to either API when both are used
-to perform similar operations.
-
-======================
-Installation Directory
-======================
-
-This document assumes that libjpeg-turbo will be installed in the default
-directory (/opt/libjpeg-turbo on Un*x and Mac systems and
-c:\libjpeg-turbo[-gcc][64] on Windows systems.  If your installation of
-libjpeg-turbo resides in a different directory, then adjust the instructions
-accordingly.
-
-=============================
-Replacing libjpeg at Run Time
-=============================
-
-Un*x
-----
-
-If a Un*x 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
-
-({lib} = lib32 or lib64, depending on whether you wish to use the 32-bit or the
-64-bit version of libjpeg-turbo.)
-
-System administrators can also replace the libjpeg symlinks 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.
-
-Windows
--------
-
-If a Windows application is dynamically linked with libjpeg, then you can
-replace libjpeg with libjpeg-turbo at run time by backing up the application's
-copy of jpeg62.dll, jpeg7.dll, or jpeg8.dll (assuming the application has its
-own local copy of this library) and copying the corresponding DLL from
-libjpeg-turbo into the application's install directory.  The official
-libjpeg-turbo binary packages only provide jpeg62.dll.  If the application uses
-jpeg7.dll or jpeg8.dll instead, then it will be necessary to build
-libjpeg-turbo from source (see "libjpeg v7 and v8 API/ABI Emulation" below.)
-
-The following information is specific to the official libjpeg-turbo binary
-packages for Visual C++:
-
--- jpeg62.dll 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.
-
--- Features of the libjpeg API that require passing a C run-time structure,
-such as a file handle, from an application to the library will probably not
-work with jpeg62.dll, 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
----
-
-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.  Replacing the application's version of the libjpeg
-dylib 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 libjpeg-turbo dylib to its 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.
-
-========================================
-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 Un*x systems and 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 Un*x systems, you would still need to manipulate LD_LIBRARY_PATH or create
-appropriate symlinks 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 Un*x 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.
-
-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 libjpeg implementation
-that does not support them will result in a "Bogus input colorspace" error.
-Applications can trap this error in order to test whether run-time support is
-available for the colorspace extensions.
-
-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 Emulation
-===================================
-
-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 were
-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) made
-the switch that there was a demand to emulate the libjpeg v7 and v8 ABIs
-in libjpeg-turbo.  It should be noted, however, that this feature was added
-primarily so that applications that had already been compiled to use libjpeg
-v7+ could take advantage of accelerated baseline JPEG encoding/decoding
-without recompiling.  libjpeg-turbo does not claim to support all of the
-libjpeg v7+ features, nor to produce identical output to libjpeg v7+ in all
-cases (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 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.
-
-Support for libjpeg v7 and v8 Features:
----------------------------------------
-
-Fully supported:
-
--- libjpeg: IDCT scaling extensions in decompressor
-   libjpeg-turbo supports IDCT scaling with scaling factors of 1/8, 1/4, 3/8,
-   1/2, 5/8, 3/4, 7/8, 9/8, 5/4, 11/8, 3/2, 13/8, 7/4, 15/8, and 2/1 (only 1/4
-   and 1/2 are SIMD-accelerated.)
-
--- libjpeg: arithmetic coding
-
--- libjpeg: In-memory source and destination managers
-   See notes below.
-
--- 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
-
--- cjpeg: -rgb option
-
--- jpegtran: lossless cropping
-
--- jpegtran: -perfect option
-
--- jpegtran: forcing width/height when performing lossless crop
-
--- rdjpgcom: -raw option
-
--- rdjpgcom: locale awareness
-
-
-Not supported:
-
-NOTE:  As of this writing, extensive research has been conducted into the
-usefulness of DCT scaling as a means of data reduction and SmartScale as a
-means of quality improvement.  The reader is invited to peruse the research at
-http://www.libjpeg-turbo.org/About/SmartScale and draw his/her own conclusions,
-but it is the general belief of our project that these features have not
-demonstrated sufficient usefulness to justify inclusion in libjpeg-turbo.
-
--- libjpeg: DCT scaling in compressor
-   cinfo.scale_num and cinfo.scale_denom are silently ignored.
-   There is no technical reason why DCT scaling could not be supported when
-   emulating the libjpeg v7+ API/ABI, but without the SmartScale extension (see
-   below), only scaling factors of 1/2, 8/15, 4/7, 8/13, 2/3, 8/11, 4/5, and
-   8/9 would be available, 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.  Providing support for this new format would be
-   feasible (particularly without full acceleration.)  However, until/unless
-   the format becomes either an official industry standard or, at minimum, an
-   accepted solution in the community, we are hesitant to implement it, as
-   there is no sense of whether or how it might change in the future.  It is
-   our belief that SmartScale has not demonstrated sufficient usefulness as a
-   lossless format nor as a means of quality enhancement, and thus, our primary
-   interest in providing this feature would be as a means of supporting
-   additional DCT scaling factors.
-
--- 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.
-
-What About libjpeg v9?
-----------------------
-
-libjpeg v9 introduced yet another field to the JPEG compression structure
-(color_transform), thus making the ABI backward incompatible with that of
-libjpeg v8.  This new field was introduced solely for the purpose of supporting
-lossless SmartScale encoding.  Further, there was actually no reason to extend
-the API in this manner, as the color transform could have just as easily been
-activated by way of a new JPEG colorspace constant, thus preserving backward
-ABI compatibility.
-
-Our research (see link above) has shown that lossless SmartScale does not
-generally accomplish anything that can't already be accomplished better with
-existing, standard lossless formats.  Thus, at this time, it is our belief that
-there is not sufficient technical justification for software to upgrade from
-libjpeg v8 to libjpeg v9, and therefore, not sufficient technical justification
-for us to emulate the libjpeg v9 ABI.
-
-=====================================
-In-Memory Source/Destination Managers
-=====================================
-
-By default, libjpeg-turbo 1.3 and later includes the jpeg_mem_src() and
-jpeg_mem_dest() functions, even when not emulating the libjpeg v8 API/ABI.
-Previously, it was necessary to build libjpeg-turbo from source with libjpeg v8
-API/ABI emulation in order to use the in-memory source/destination managers,
-but several projects requested that those functions be included when emulating
-the libjpeg v6b API/ABI as well.  This allows the use of those functions by
-programs that need them without breaking ABI compatibility for programs that
-don't, and it allows those functions to be provided in the "official"
-libjpeg-turbo binaries.
-
-Those who are concerned about maintaining strict conformance with the libjpeg
-v6b or v7 API can pass an argument of --without-mem-srcdst to configure or
-an argument of -DWITH_MEM_SRCDST=0 to CMake prior to building libjpeg-turbo.
-This will restore the pre-1.3 behavior, in which jpeg_mem_src() and
-jpeg_mem_dest() are only included when emulating the libjpeg v8 API/ABI.
-
-On Un*x systems, including the in-memory source/destination managers changes
-the dynamic library version from 62.0.0 to 62.1.0 if using libjpeg v6b API/ABI
-emulation and from 7.0.0 to 7.1.0 if using libjpeg v7 API/ABI emulation.
-
-Note that, on most Un*x systems, the dynamic linker will not look for a
-function in a library until that function is actually used.  Thus, if a program
-is built against libjpeg-turbo 1.3+ and uses jpeg_mem_src() or jpeg_mem_dest(),
-that program will not fail if run against an older version of libjpeg-turbo or
-against libjpeg v7- until the program actually tries to call jpeg_mem_src() or

-
-For the most part, libjpeg-turbo should produce identical output to libjpeg
-v6b.  The one exception to this is when using the floating point DCT/IDCT, in
-which case the outputs of libjpeg v6b and libjpeg-turbo are not guaranteed to
-be identical (the accuracy of the floating point DCT/IDCT is constant when

-
-While libjpeg-turbo does emulate the libjpeg v8 API/ABI, under the hood, it is
-still using the same algorithms as libjpeg v6b, so there are several specific
-cases in which libjpeg-turbo cannot be expected to produce the same output as
-libjpeg v8:
-
--- When decompressing using scaling factors of 1/2 and 1/4, because libjpeg v8
-   implements those scaling algorithms a bit differently than libjpeg v6b does,
-   and libjpeg-turbo's SIMD extensions are based on the libjpeg v6b behavior.
-
--- When using chrominance subsampling, because libjpeg v8 implements this
-   with its DCT/IDCT scaling algorithms rather than with a separate
-   downsampling/upsampling algorithm.
-
--- When using the floating point IDCT, for the reasons stated above and also
-   because the floating point IDCT algorithm was modified in libjpeg v8a to
-   improve accuracy.
-
--- When decompressing using a scaling factor > 1 and merged (AKA "non-fancy" or
-   "non-smooth") chrominance upsampling, because libjpeg v8 does not support
-   merged upsampling with scaling factors > 1.

-
-===============
-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

-===============================================
-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

-It is therefore strongly advised that you use the slow integer forward DCT
-whenever encoding images with a JPEG quality of 98 or higher.

+Background
+==========
+
+libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2,
+AVX2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression
+on x86, x86-64, ARM, and PowerPC systems, as well as progressive JPEG
+compression on x86 and x86-64 systems.  On such systems, libjpeg-turbo is
+generally 2-6x as fast as libjpeg, all else being equal.  On other types of
+systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by
+virtue of its highly-optimized Huffman coding routines.  In many cases, the
+performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
+
+libjpeg-turbo implements both the traditional libjpeg API as well as the less
+powerful but more straightforward TurboJPEG API.  libjpeg-turbo also features
+colorspace extensions that allow it to compress from/decompress to 32-bit and
+big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java
+interface.
+
+libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated
+derivative of libjpeg v6b developed by Miyasaka Masaru.  The TigerVNC and
+VirtualGL projects made numerous enhancements to the codec in 2009, and in
+early 2010, libjpeg-turbo spun off into an independent project, with the goal
+of making high-speed JPEG compression/decompression technology available to a
+broader range of users and developers.
+
+
+License
+=======
+
+libjpeg-turbo is covered by three compatible BSD-style open source licenses.
+Refer to [LICENSE.md](LICENSE.md) for a roll-up of license terms.
+
+
+Building libjpeg-turbo
+======================
+
+Refer to [BUILDING.md](BUILDING.md) for complete instructions.
+
+
+Using libjpeg-turbo
+===================
+
+libjpeg-turbo includes two APIs that can be used to compress and decompress
+JPEG images:
+
+- **TurboJPEG API**<br>
+  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.  The TurboJPEG API is recommended for first-time
+  users of libjpeg-turbo.  Refer to [tjexample.c](tjexample.c) and
+  [TJExample.java](java/TJExample.java) for examples of its usage and to
+  <http://libjpeg-turbo.org/Documentation/Documentation> for API documentation.
+
+- **libjpeg API**<br>
+  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.  The libjpeg API implementation in 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.)  Refer to [cjpeg.c](cjpeg.c) and [djpeg.c](djpeg.c) for examples
+  of its usage and to [libjpeg.txt](libjpeg.txt) for API documentation.
+
+There is no significant performance advantage to either API when both are used
+to perform similar operations.
+
+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 libjpeg implementation
+that does not support them will result in a "Bogus input colorspace" error.
+Applications can trap this error in order to test whether run-time support is
+available for the colorspace extensions.
+
+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](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 Emulation
+-----------------------------------
+
+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 were
+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 not
+as widely used as v6b, enough programs (including a few Linux distros) made
+the switch that there was a demand to emulate the libjpeg v7 and v8 ABIs
+in libjpeg-turbo.  It should be noted, however, that this feature was added
+primarily so that applications that had already been compiled to use libjpeg
+v7+ could take advantage of accelerated baseline JPEG encoding/decoding
+without recompiling.  libjpeg-turbo does not claim to support all of the
+libjpeg v7+ features, nor to produce identical output to libjpeg v7+ in all
+cases (see below.)
+
+By passing 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 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.
+
+### Support for libjpeg v7 and v8 Features
+
+#### Fully supported
+
+- **libjpeg: IDCT scaling extensions in decompressor**<br>
+  libjpeg-turbo supports IDCT scaling with scaling factors of 1/8, 1/4, 3/8,
+  1/2, 5/8, 3/4, 7/8, 9/8, 5/4, 11/8, 3/2, 13/8, 7/4, 15/8, and 2/1 (only 1/4
+  and 1/2 are SIMD-accelerated.)
+
+- **libjpeg: Arithmetic coding**
+
+- **libjpeg: In-memory source and destination managers**<br>
+  See notes below.
+
+- **cjpeg: Separate quality settings for luminance and chrominance**<br>
+  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**
+
+- **cjpeg: `-rgb` option**
+
+- **jpegtran: Lossless cropping**
+
+- **jpegtran: `-perfect` option**
+
+- **jpegtran: Forcing width/height when performing lossless crop**
+
+- **rdjpgcom: `-raw` option**
+
+- **rdjpgcom: Locale awareness**
+
+
+#### Not supported
+
+NOTE:  As of this writing, extensive research has been conducted into the
+usefulness of DCT scaling as a means of data reduction and SmartScale as a
+means of quality improvement.  The reader is invited to peruse the research at
+<http://www.libjpeg-turbo.org/About/SmartScale> and draw his/her own conclusions,
+but it is the general belief of our project that these features have not
+demonstrated sufficient usefulness to justify inclusion in libjpeg-turbo.
+
+- **libjpeg: DCT scaling in compressor**<br>
+  `cinfo.scale_num` and `cinfo.scale_denom` are silently ignored.
+  There is no technical reason why DCT scaling could not be supported when
+  emulating the libjpeg v7+ API/ABI, but without the SmartScale extension (see
+  below), only scaling factors of 1/2, 8/15, 4/7, 8/13, 2/3, 8/11, 4/5, and
+  8/9 would be available, which is of limited usefulness.
+
+- **libjpeg: SmartScale**<br>
+  `cinfo.block_size` is silently ignored.
+  SmartScale is an extension to the JPEG format that allows for DCT block
+  sizes other than 8x8.  Providing support for this new format would be
+  feasible (particularly without full acceleration.)  However, until/unless
+  the format becomes either an official industry standard or, at minimum, an
+  accepted solution in the community, we are hesitant to implement it, as
+  there is no sense of whether or how it might change in the future.  It is
+  our belief that SmartScale has not demonstrated sufficient usefulness as a
+  lossless format nor as a means of quality enhancement, and thus our primary
+  interest in providing this feature would be as a means of supporting
+  additional DCT scaling factors.
+
+- **libjpeg: Fancy downsampling in compressor**<br>
+  `cinfo.do_fancy_downsampling` is silently ignored.
+  This requires the DCT scaling feature, which is not supported.
+
+- **jpegtran: Scaling**<br>
+  This requires both the DCT scaling and SmartScale features, which are not
+  supported.
+
+- **Lossless RGB JPEG files**<br>
+  This requires the SmartScale feature, which is not supported.
+
+### What About libjpeg v9?
+
+libjpeg v9 introduced yet another field to the JPEG compression structure
+(`color_transform`), thus making the ABI backward incompatible with that of
+libjpeg v8.  This new field was introduced solely for the purpose of supporting
+lossless SmartScale encoding.  Furthermore, there was actually no reason to
+extend the API in this manner, as the color transform could have just as easily
+been activated by way of a new JPEG colorspace constant, thus preserving
+backward ABI compatibility.
+
+Our research (see link above) has shown that lossless SmartScale does not
+generally accomplish anything that can't already be accomplished better with
+existing, standard lossless formats.  Therefore, at this time it is our belief
+that there is not sufficient technical justification for software projects to
+upgrade from libjpeg v8 to libjpeg v9, and thus there is not sufficient
+technical justification for us to emulate the libjpeg v9 ABI.
+
+In-Memory Source/Destination Managers
+-------------------------------------
+
+By default, libjpeg-turbo 1.3 and later includes the `jpeg_mem_src()` and
+`jpeg_mem_dest()` functions, even when not emulating the libjpeg v8 API/ABI.
+Previously, it was necessary to build libjpeg-turbo from source with libjpeg v8
+API/ABI emulation in order to use the in-memory source/destination managers,
+but several projects requested that those functions be included when emulating
+the libjpeg v6b API/ABI as well.  This allows the use of those functions by
+programs that need them, without breaking ABI compatibility for programs that
+don't, and it allows those functions to be provided in the "official"
+libjpeg-turbo binaries.
+
+Those who are concerned about maintaining strict conformance with the libjpeg
+v6b or v7 API can pass an argument of `-DWITH_MEM_SRCDST=0` to `cmake` prior to
+building libjpeg-turbo.  This will restore the pre-1.3 behavior, in which
+`jpeg_mem_src()` and `jpeg_mem_dest()` are only included when emulating the
+libjpeg v8 API/ABI.
+
+On Un*x systems, including the in-memory source/destination managers changes
+the dynamic library version from 62.1.0 to 62.2.0 if using libjpeg v6b API/ABI
+emulation and from 7.1.0 to 7.2.0 if using libjpeg v7 API/ABI emulation.
+
+Note that, on most Un*x systems, the dynamic linker will not look for a
+function in a library until that function is actually used.  Thus, if a program
+is built against libjpeg-turbo 1.3+ and uses `jpeg_mem_src()` or
+`jpeg_mem_dest()`, that program will not fail if run against an older version
+of libjpeg-turbo or against libjpeg v7- until the program actually tries to
+call `jpeg_mem_src()` or `jpeg_mem_dest()`.  Such is not the case on Windows.
+If a program is built against the libjpeg-turbo 1.3+ DLL and uses
+`jpeg_mem_src()` or `jpeg_mem_dest()`, then it must use the libjpeg-turbo 1.3+
+DLL at run time.
+
+Both cjpeg and djpeg have been extended to allow testing the in-memory
+source/destination manager functions.  See their respective man pages for more
+details.
+
+
+Mathematical Compatibility
+==========================
+
+For the most part, libjpeg-turbo should produce identical output to libjpeg
+v6b.  The one exception to this is when using the floating point DCT/IDCT, in
+which case the outputs of libjpeg v6b and libjpeg-turbo can differ for the
+following reasons:
+
+- The SSE/SSE2 floating point DCT implementation in libjpeg-turbo is ever so
+  slightly more accurate than the implementation in libjpeg v6b, but not by
+  any amount perceptible to human vision (generally in the range of 0.01 to
+  0.08 dB gain in PNSR.)
+
+- When not using the SIMD extensions, libjpeg-turbo uses the more accurate
+  (and slightly faster) floating point IDCT algorithm introduced in libjpeg
+  v8a as opposed to the algorithm used in libjpeg v6b.  It should be noted,
+  however, that this algorithm basically brings the accuracy of the floating
+  point IDCT in line with the accuracy of the slow integer IDCT.  The floating
+  point DCT/IDCT algorithms are mainly a legacy feature, and they do not
+  produce significantly more accuracy than the slow integer algorithms (to put
+  numbers on this, the typical difference in PNSR between the two algorithms
+  is less than 0.10 dB, whereas changing the quality level by 1 in the upper
+  range of the quality scale is typically more like a 1.0 dB difference.)
+
+- If the floating point algorithms in libjpeg-turbo are not implemented using
+  SIMD instructions on a particular platform, then the accuracy of the
+  floating point DCT/IDCT can depend on the compiler settings.
+
+While libjpeg-turbo does emulate the libjpeg v8 API/ABI, under the hood it is
+still using the same algorithms as libjpeg v6b, so there are several specific
+cases in which libjpeg-turbo cannot be expected to produce the same output as
+libjpeg v8:
+
+- When decompressing using scaling factors of 1/2 and 1/4, because libjpeg v8
+  implements those scaling algorithms differently than libjpeg v6b does, and
+  libjpeg-turbo's SIMD extensions are based on the libjpeg v6b behavior.
+
+- When using chrominance subsampling, because libjpeg v8 implements this
+  with its DCT/IDCT scaling algorithms rather than with a separate
+  downsampling/upsampling algorithm.  In our testing, the subsampled/upsampled
+  output of libjpeg v8 is less accurate than that of libjpeg v6b for this
+  reason.
+
+- When decompressing using a scaling factor > 1 and merged (AKA "non-fancy" or
+  "non-smooth") chrominance upsampling, because libjpeg v8 does not support
+  merged upsampling with scaling factors > 1.
+
+
+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.
+
+
+Memory Debugger Pitfalls
+========================
+
+Valgrind and Memory Sanitizer (MSan) can generate false positives
+(specifically, incorrect reports of uninitialized memory accesses) when used
+with libjpeg-turbo's SIMD extensions.  It is generally recommended that the
+SIMD extensions be disabled, either by passing an argument of `-DWITH_SIMD=0`
+to `cmake` when configuring the build or by setting the environment variable
+`JSIMD_FORCENONE` to `1` at run time, when testing libjpeg-turbo with Valgrind,
+MSan, or other memory debuggers.

 Use fast integer DCT (less accurate).
+In libjpeg-turbo, the fast method is generally about 5-15% faster than the int
+method when using the x86/x86-64 SIMD extensions (results may vary with other
+SIMD implementations, or when using libjpeg-turbo without SIMD extensions.)
+For quality levels of 90 and below, there should be little or no perceptible
+difference between the two algorithms.  For quality levels above 90, however,
+the difference between the fast and the int methods becomes more pronounced.
+With quality=97, for instance, the fast method incurs generally about a 1-3 dB
+loss (in PSNR) relative to the int method, but this can be larger for some
+images.  Do not use the fast method with quality levels above 97.  The
+algorithm often degenerates at quality=98 and above and can actually produce a

+#   user executables (``bin``)
+# ``SBINDIR``
+#   system admin executables (``sbin``)

+# Special Cases
+# ^^^^^^^^^^^^^
+#
+# The following values of :variable:`CMAKE_INSTALL_PREFIX` are special:
+#
+# ``/``
+#
+#   For ``<dir>`` other than the ``SYSCONFDIR`` and ``LOCALSTATEDIR``,
+#   the value of ``CMAKE_INSTALL_<dir>`` is prefixed with ``usr/`` if
+#   it is not user-specified as an absolute path.  For example, the
+#   ``INCLUDEDIR`` value ``include`` becomes ``usr/include``.
+#   This is required by the `GNU Coding Standards`_, which state:
+#
+#     When building the complete GNU system, the prefix will be empty
+#     and ``/usr`` will be a symbolic link to ``/``.
+#
+# ``/usr``
+#
+#   For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
+#   ``CMAKE_INSTALL_FULL_<dir>`` is computed by prepending just ``/``
+#   to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
+#   as an absolute path.  For example, the ``SYSCONFDIR`` value ``etc``
+#   becomes ``/etc``.  This is required by the `GNU Coding Standards`_.
+#
+# ``/opt/...``
+#
+#   For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
+#   ``CMAKE_INSTALL_FULL_<dir>`` is computed by *appending* the prefix
+#   to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
+#   as an absolute path.  For example, the ``SYSCONFDIR`` value ``etc``
+#   becomes ``/etc/opt/...``.  This is defined by the
+#   `Filesystem Hierarchy Standard`_.
+#
+# .. _`Filesystem Hierarchy Standard`: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
+#
+# Macros
+# ^^^^^^
+#
+# .. command:: GNUInstallDirs_get_absolute_install_dir
+#
+#   ::
+#
+#     GNUInstallDirs_get_absolute_install_dir(absvar var)
+#
+#   Set the given variable ``absvar`` to the absolute path contained
+#   within the variable ``var``.  This is to allow the computation of an
+#   absolute path, accounting for all the special cases documented
+#   above.  While this macro is used to compute the various
+#   ``CMAKE_INSTALL_FULL_<dir>`` variables, it is exposed publicly to
+#   allow users who create additional path variables to also compute
+#   absolute paths where necessary, using the same logic.

 .B \-dct fast
 Use fast integer DCT (less accurate).
+In libjpeg-turbo, the fast method is generally about 5-15% faster than the int
+method when using the x86/x86-64 SIMD extensions (results may vary with other
+SIMD implementations, or when using libjpeg-turbo without SIMD extensions.)  If
+the JPEG image was compressed using a quality level of 85 or below, then there
+should be little or no perceptible difference between the two algorithms.  When
+decompressing images that were compressed using quality levels above 85,
+however, the difference between the fast and int methods becomes more
+pronounced.  With images compressed using quality=97, for instance, the fast
+method incurs generally about a 4-6 dB loss (in PSNR) relative to the int
+method, but this can be larger for some images.  If you can avoid it, do not
+use the fast method when decompressing images that were compressed using
+quality levels above 97.  The algorithm often degenerates for such images and
+can actually produce a more lossy output image than if the JPEG image had been
+compressed using lower quality levels.
 .TP
 .B \-dct float
 Use floating-point DCT method.
-The float method is very slightly more accurate than the int method, but is
-much slower unless your machine has very fast floating-point hardware.  Also
-note that results of the floating-point method may vary slightly across
-machines, while the integer methods should give the same results everywhere.
-The fast integer method is much less accurate than the other two.
+The float method is mainly a legacy feature.  It does not produce significantly
+more accurate results than the int method, and it is much slower.  The float
+method may also give different results on different machines due to varying

+<div class="block">This class encapsulates a YUV planar image and the metadata
+ associated with it.  The TurboJPEG API allows both the JPEG compression and
+ decompression pipelines to be split into stages:  YUV encode, compress from
+ YUV, decompress to YUV, and YUV decode.  A <code>YUVImage</code> instance
+ serves as the destination image for YUV encode and decompress-to-YUV
+ operations and as the source image for compress-from-YUV and YUV decode
+ operations.
+ <p>
+ Technically, the JPEG format uses the YCbCr colorspace (which technically is
+ not a "colorspace" but rather a "color transform"), but per the convention
+ of the digital video community, the TurboJPEG API uses "YUV" to refer to an
+ image format consisting of Y, Cb, and Cr image planes.
+ <p>
+ Each plane is simply a 2D array of bytes, each byte representing the value
+ of one of the components (Y, Cb, or Cr) at a particular location in the
+ image.  The width and height of each plane are determined by the image
+ width, height, and level of chrominance subsampling.  The luminance plane
+ width is the image width padded to the nearest multiple of the horizontal
+ subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of
+ 4:1:1, 1 in the case of 4:4:4 or grayscale.)  Similarly, the luminance plane
+ height is the image height padded to the nearest multiple of the vertical
+ subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4
+ or grayscale.)  The chrominance plane width is equal to the luminance plane
+ width divided by the horizontal subsampling factor, and the chrominance
+ plane height is equal to the luminance plane height divided by the vertical
+ subsampling factor.
+ <p>
+ For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is
+ used, then the luminance plane would be 36 x 35 bytes, and each of the
+ chrominance planes would be 18 x 35 bytes.  If you specify a line padding of
+ 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and
+ each of the chrominance planes would be 20 x 35 bytes.</div>

+/**
+ * This class encapsulates a YUV planar image and the metadata
+ * associated with it.  The TurboJPEG API allows both the JPEG compression and
+ * decompression pipelines to be split into stages:  YUV encode, compress from
+ * YUV, decompress to YUV, and YUV decode.  A <code>YUVImage</code> instance
+ * serves as the destination image for YUV encode and decompress-to-YUV
+ * operations and as the source image for compress-from-YUV and YUV decode
+ * operations.
+ * <p>
+ * Technically, the JPEG format uses the YCbCr colorspace (which technically is
+ * not a "colorspace" but rather a "color transform"), but per the convention
+ * of the digital video community, the TurboJPEG API uses "YUV" to refer to an
+ * image format consisting of Y, Cb, and Cr image planes.
+ * <p>
+ * Each plane is simply a 2D array of bytes, each byte representing the value
+ * of one of the components (Y, Cb, or Cr) at a particular location in the
+ * image.  The width and height of each plane are determined by the image
+ * width, height, and level of chrominance subsampling.  The luminance plane
+ * width is the image width padded to the nearest multiple of the horizontal
+ * subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of
+ * 4:1:1, 1 in the case of 4:4:4 or grayscale.)  Similarly, the luminance plane
+ * height is the image height padded to the nearest multiple of the vertical
+ * subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4
+ * or grayscale.)  The chrominance plane width is equal to the luminance plane
+ * width divided by the horizontal subsampling factor, and the chrominance
+ * plane height is equal to the luminance plane height divided by the vertical
+ * subsampling factor.
+ * <p>
+ * For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is
+ * used, then the luminance plane would be 36 x 35 bytes, and each of the
+ * chrominance planes would be 18 x 35 bytes.  If you specify a line padding of
+ * 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and
+ * each of the chrominance planes would be 20 x 35 bytes.
