+Building libjpeg-turbo
+======================
+
+
+Build Requirements
+------------------
+
+
+### All Systems
+
+- [CMake](https://cmake.org) v2.8.12 or later
+
+- [NASM](https://nasm.us) or [Yasm](https://yasm.tortall.net)
+  (if building x86 or x86-64 SIMD extensions)
+  * If using NASM, 2.13 or later is required.
+  * If using Yasm, 1.2.0 or later is required.
+  * NASM 2.15 or later is required if building libjpeg-turbo with Intel
+    Control-flow Enforcement Technology (CET) support.
+  * If building on macOS, NASM or Yasm can be obtained from
+    [MacPorts](https://macports.org) or [Homebrew](https://brew.sh).
+     - 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 NASM 2.14 or later or Yasm must be used when
+       building libjpeg-turbo.
+  * If NASM or Yasm is not in your `PATH`, then you can specify the full path
+    to the assembler by using either the `CMAKE_ASM_NASM_COMPILER` CMake
+    variable or the `ASM_NASM` environment variable.  On Windows, use forward
+    slashes rather than backslashes in the path (for example,
+    **c:/nasm/nasm.exe**).
+  * NASM and Yasm are located in the CRB (Code Ready Builder) or PowerTools
+    repository on Red Hat Enterprise Linux 8+ and derivatives, which is not
+    enabled by default.
+
+### 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.  For other systems, you can obtain the Oracle Java
+  Development Kit from
+  <https://oracle.com/java/technologies/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
+  [Visual Studio Community Edition](https://visualstudio.microsoft.com),
+  which includes everything necessary to build libjpeg-turbo.
+
+  * You can also download and install the standalone Windows SDK (for Windows 7
+    or later), which includes command-line versions of the 32-bit and 64-bit
+    Visual C++ compilers.
+  * 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`, which are located in the same
+    directory as the compiler.
+  * If built with Visual C++ 2015 or later, the libjpeg-turbo static libraries
+    cannot be used with earlier versions of Visual C++, and vice versa.
+  * The libjpeg API DLL (**jpeg{version}.dll**) will depend on the C run-time
+    DLLs corresponding to the version of Visual C++ that was used to build it.
+    
+- Vcpkg
+  
+  You need to download and install libpng using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
+
+      git clone https://github.com/Microsoft/vcpkg.git
+      cd vcpkg
+      ./bootstrap-vcpkg.bat
+      ./vcpkg integrate install
+      ./vcpkg install libpng:x64-windows
+      ./vcpkg install libpng:x64-windows-static
+      
+  Actually, you can just download and install MozJPEG using vcpkg dependency manager:
+      
+      ./vcpkg install mozjpeg
+  
+  The mozjpeg port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+
+   ... OR ...
+
+
+- MinGW
+
+  [MSYS2](https://msys2.org) or [tdm-gcc](https://jmeubank.github.io/tdm-gcc)
+  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
+  <https://oracle.com/java/technologies/downloads>.
+
+  * If using JDK 11 or later, CMake 3.10.x or later must also be used.
+
+
+Sub-Project Builds
+------------------
+
+The libjpeg-turbo build system does not support being included as a sub-project
+using the CMake `add_subdirectory()` function.  Use the CMake
+`ExternalProject_Add()` function instead.
+
+
+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.
+
+
+Ninja
+-----
+
+If using Ninja, then replace `make` or `nmake` with `ninja`, and replace the
+CMake generator (specified with the `-G` option) with `Ninja`, in all of the
+procedures and recipes below.
+
+
+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.
+
+
+### 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
+
+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
+following contents:
+
+    set(CMAKE_SYSTEM_NAME Windows)
+    set(CMAKE_SYSTEM_PROCESSOR X86)
+    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 \
+      -DCMAKE_INSTALL_PREFIX={install_path} \
+      [additional CMake flags] {source_directory}
+    make
+
+*{install\_path}* is the path under which the libjpeg-turbo binaries should be
+installed.
+
+
+### 64-bit MinGW Build on Un*x (including Mac and Cygwin)
+
+Create a file called **toolchain.cmake** under *{build_directory}*, with the
+following contents:
+
+    set(CMAKE_SYSTEM_NAME Windows)
+    set(CMAKE_SYSTEM_PROCESSOR AMD64)
+    set(CMAKE_C_COMPILER {mingw_binary_path}/x86_64-w64-mingw32-gcc)
+    set(CMAKE_RC_COMPILER {mingw_binary_path}/x86_64-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 \
+      -DCMAKE_INSTALL_PREFIX={install_path} \
+      [additional CMake flags] {source_directory}
+    make
+
+*{install\_path}* is the path under which the libjpeg-turbo binaries should be
+installed.
+
+
+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.
+
+
+### Armv8 (64-bit)
+
+**Xcode 5 or later required, Xcode 6.3.x or later recommended**
+
+The following script demonstrates how to build libjpeg-turbo to run on the
+iPhone 5S/iPad Mini 2/iPad Air and newer.
+
+    IOS_PLATFORMDIR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform
+    IOS_SYSROOT=($IOS_PLATFORMDIR/Developer/SDKs/iPhoneOS*.sdk)
+    export CFLAGS="-Wall -miphoneos-version-min=8.0 -funwind-tables"
+
+    cd {build_directory}
+
+    cmake -G"Unix Makefiles" \
+      -DCMAKE_C_COMPILER=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang \
+      -DCMAKE_OSX_ARCHITECTURES=arm64 \
+      -DCMAKE_OSX_SYSROOT=${IOS_SYSROOT[0]} \
+      [additional CMake flags] {source_directory}
+    make
+
+Replace `iPhoneOS` with `iPhoneSimulator` and `-miphoneos-version-min` with
+`-miphonesimulator-version-min` to build libjpeg-turbo for the iOS simulator on
+Macs with Apple silicon CPUs.
+
+
+Building libjpeg-turbo for Android
+----------------------------------
+
+Building libjpeg-turbo for Android platforms requires v13b or later of the
+[Android NDK](https://developer.android.com/ndk).
+
+
+### Armv7 (32-bit)
+
+**NDK r19 or later with Clang recommended**
+
+The following is a general recipe script that can be modified for your specific
+needs.

+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**.
+
+
+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/macOS 10.7 and later.
+
+In order to create a Mac package/disk image that contains universal
+x86-64/Arm binaries, set the following CMake variable:
+
+* `SECONDARY_BUILD`: Directory containing a cross-compiled x86-64 or Armv8
+  (64-bit) iOS or macOS build of libjpeg-turbo to include in the universal
+  binaries
+
+You should first use CMake to configure the cross-compiled x86-64 or Armv8
+secondary build of libjpeg-turbo (see "Building libjpeg-turbo for iOS" above,
+if applicable) in a build directory that matches the one specified in the
+aforementioned CMake variable.  Next, configure the primary (native) build of
+libjpeg-turbo as an out-of-tree build, specifying the aforementioned CMake
+variable, and build it.  Once the primary build has been built, run `make dmg`
+from the build directory.  The packaging system will build the secondary build,
+use lipo to combine it with the primary build into a single set of universal
+binaries, then package the universal binaries.
+
+
+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](https://nsis.sourceforge.io).  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.

+libjpeg-turbo Licenses
+======================
+
+libjpeg-turbo is covered by two 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,
+  including any code inherited from libjpeg and any modifications to that
+  code.  Note that the libjpeg-turbo SIMD source code bears the
+  [zlib License](https://opensource.org/licenses/Zlib), but in the context of
+  the overall libjpeg API library, the terms of the zlib License are subsumed
+  by the terms of the IJG License.
+
+- The Modified (3-clause) BSD License, which is listed below
+
+  This license applies to the TurboJPEG API library and associated programs, as
+  well as the build system.  Note that the TurboJPEG API library wraps the
+  libjpeg API library, so in the context of the overall TurboJPEG API library,
+  both the terms of the IJG License and the terms of the Modified (3-clause)
+  BSD License apply.
+
+
+Complying with the libjpeg-turbo Licenses
+=========================================
+
+This section provides a roll-up of the libjpeg-turbo licensing terms, to the
+best of our understanding.  This is not a license in and of itself.  It is
+intended solely for clarification.
+
+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.

+Why Two Licenses?
+=================
+
+The zlib License could have been used instead of the Modified (3-clause) BSD

+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.

-
-OVERVIEW
-========
-
-This package contains C software to implement JPEG image compression and
-decompression.  JPEG (pronounced "jay-peg") is a standardized compression
-method for full-color and gray-scale images.  JPEG is intended for compressing
-"real-world" scenes; line drawings, cartoons and other non-realistic images
-are not its strong suit.  JPEG is lossy, meaning that the output image is not
-exactly identical to the input image.  Hence you must not use JPEG if you
-have to have identical output bits.  However, on typical photographic images,
-very good compression levels can be obtained with no visible change, and
-remarkably high compression levels are possible if you can tolerate a
-low-quality image.  For more details, see the references, or just experiment
-with various compression settings.
-
-This software implements JPEG baseline, extended-sequential, and progressive
-compression processes.  Provision is made for supporting all variants of these
-processes, although some uncommon parameter settings aren't implemented yet.
-For legal reasons, we are not distributing code for the arithmetic-coding
-variants of JPEG; see LEGAL ISSUES.  We have made no provision for supporting
-the hierarchical or lossless processes defined in the standard.
-
-We provide a set of library routines for reading and writing JPEG image files,
-plus two sample applications "cjpeg" and "djpeg", which use the library to
-perform conversion between JPEG and some other popular image file formats.
-The library is intended to be reused in other applications.
-
-In order to support file conversion and viewing software, we have included
-considerable functionality beyond the bare JPEG coding/decoding capability;
-for example, the color quantization modules are not strictly part of JPEG
-decoding, but they are essential for output to colormapped file formats or
-colormapped displays.  These extra functions can be compiled out of the
-library if not required for a particular application.  We have also included
-"jpegtran", a utility for lossless transcoding between different JPEG
-processes, and "rdjpgcom" and "wrjpgcom", two simple applications for
-inserting and extracting textual comments in JFIF files.
-
-The emphasis in designing this software has been on achieving portability and
-flexibility, while also making it fast enough to be useful.  In particular,
-the software is not intended to be read as a tutorial on JPEG.  (See the
-REFERENCES section for introductory material.)  Rather, it is intended to
-be reliable, portable, industrial-strength code.  We do not claim to have
-achieved that goal in every aspect of the software, but we strive for it.
-
-We welcome the use of this software as a component of commercial products.
-No royalty is required, but we do ask for an acknowledgement in product
-documentation, as described under LEGAL ISSUES.

-
-1. We don't promise that this software works.  (But if you find any bugs,
-   please let us know!)
-2. You can use this software for whatever you want.  You don't have to pay us.
-3. You may not pretend that you wrote this software.  If you use it in a
-   program, you must acknowledge somewhere in your documentation that
-   you've used the IJG code.
-
-In legalese:
-
-The authors make NO WARRANTY or representation, either express or implied,
-with respect to this software, its quality, accuracy, merchantability, or
-fitness for a particular purpose.  This software is provided "AS IS", and you,
-its user, assume the entire risk as to its quality and accuracy.
-
-This software is copyright (C) 1991-1998, Thomas G. Lane.
-All Rights Reserved except as specified below.
-
-Permission is hereby granted to use, copy, modify, and distribute this
-software (or portions thereof) for any purpose, without fee, subject to these
-conditions:
-(1) If any part of the source code for this software is distributed, then this
-README file must be included, with this copyright and no-warranty notice
-unaltered; and any additions, deletions, or changes to the original files
-must be clearly indicated in accompanying documentation.
-(2) If only executable code is distributed, then the accompanying
-documentation must state that "this software is based in part on the work of
-the Independent JPEG Group".
-(3) Permission for use of this software is granted only if the user accepts
-full responsibility for any undesirable consequences; the authors accept
-NO LIABILITY for damages of any kind.
-
-These conditions apply to any software derived from or based on the IJG code,
-not just to the unmodified library.  If you use our work, you ought to
-acknowledge us.
-
-Permission is NOT granted for the use of any IJG author's name or company name
-in advertising or publicity relating to this software or products derived from
-it.  This software may be referred to only as "the Independent JPEG Group's
-software".
-
-We specifically permit and encourage the use of this software as the basis of

-assumed by the product vendor.
-
-
-ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
-sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.
-ansi2knr.c is NOT covered by the above copyright and conditions, but instead
-by the usual distribution terms of the Free Software Foundation; principally,
-that you must include source code if you redistribute it.  (See the file
-ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
-of any program generated from the IJG code, this does not limit you more than
-the foregoing paragraphs do.
-
-The Unix configuration script "configure" was produced with GNU Autoconf.
-It is copyright by the Free Software Foundation but is freely distributable.
-The same holds for its supporting scripts (config.guess, config.sub,
-ltconfig, ltmain.sh).  Another support script, install-sh, is copyright
-by M.I.T. but is also freely distributable.
-
-It appears that the arithmetic coding option of the JPEG spec is covered by
-patents owned by IBM, AT&T, and Mitsubishi.  Hence arithmetic coding cannot
-legally be used without obtaining one or more licenses.  For this reason,
-support for arithmetic coding has been removed from the free JPEG software.
-(Since arithmetic coding provides only a marginal gain over the unpatented
-Huffman mode, it is unlikely that very many implementations will support it.)
-So far as we are aware, there are no patent restrictions on the remaining
-code.
-
-The IJG distribution formerly included code to read and write GIF files.
-To avoid entanglement with the Unisys LZW patent, GIF reading support has
-been removed altogether, and the GIF writer has been simplified to produce
-"uncompressed GIFs".  This technique does not use the LZW algorithm; the
-resulting GIF files are larger than usual, but are readable by all standard
-GIF decoders.
-
-We are required to state that
-    "The Graphics Interchange Format(c) is the Copyright property of
-    CompuServe Incorporated.  GIF(sm) is a Service Mark property of
-    CompuServe Incorporated."

-
-REFERENCES
-==========
-
-We highly recommend reading one or more of these references before trying to
-understand the innards of the JPEG software.
-
-The best short technical introduction to the JPEG compression algorithm is
-	Wallace, Gregory K.  "The JPEG Still Picture Compression Standard",
-	Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.
-(Adjacent articles in that issue discuss MPEG motion picture compression,
-applications of JPEG, and related topics.)  If you don't have the CACM issue
-handy, a PostScript file containing a revised version of Wallace's article is
-available at ftp://ftp.uu.net/graphics/jpeg/wallace.ps.gz.  The file (actually
-a preprint for an article that appeared in IEEE Trans. Consumer Electronics)
-omits the sample images that appeared in CACM, but it includes corrections
-and some added material.  Note: the Wallace article is copyright ACM and IEEE,
-and it may not be used for commercial purposes.
-
-A somewhat less technical, more leisurely introduction to JPEG can be found in
-"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by
-M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1.  This book provides
-good explanations and example C code for a multitude of compression methods
-including JPEG.  It is an excellent source if you are comfortable reading C
-code but don't know much about data compression in general.  The book's JPEG
-sample code is far from industrial-strength, but when you are ready to look
-at a full implementation, you've got one here...
-
-The best full description of JPEG is the textbook "JPEG Still Image Data
-Compression Standard" by William B. Pennebaker and Joan L. Mitchell, published
-by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1.  Price US$59.95, 638 pp.
-The book includes the complete text of the ISO JPEG standards (DIS 10918-1
-and draft DIS 10918-2).  This is by far the most complete exposition of JPEG
-in existence, and we highly recommend it.
-
-The JPEG standard itself is not available electronically; you must order a
-paper copy through ISO or ITU.  (Unless you feel a need to own a certified
-official copy, we recommend buying the Pennebaker and Mitchell book instead;
-it's much cheaper and includes a great deal of useful explanatory material.)
-In the USA, copies of the standard may be ordered from ANSI Sales at (212)
-642-4900, or from Global Engineering Documents at (800) 854-7179.  (ANSI
-doesn't take credit card orders, but Global does.)  It's not cheap: as of
-1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus 7%
-shipping/handling.  The standard is divided into two parts, Part 1 being the
-actual specification, while Part 2 covers compliance testing methods.  Part 1
-is titled "Digital Compression and Coding of Continuous-tone Still Images,
-Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS
-10918-1, ITU-T T.81.  Part 2 is titled "Digital Compression and Coding of
-Continuous-tone Still Images, Part 2: Compliance testing" and has document
-numbers ISO/IEC IS 10918-2, ITU-T T.83.
-
-Some extensions to the original JPEG standard are defined in JPEG Part 3,
-a newer ISO standard numbered ISO/IEC IS 10918-3 and ITU-T T.84.  IJG
-currently does not support any Part 3 extensions.
-
-The JPEG standard does not specify all details of an interchangeable file
-format.  For the omitted details we follow the "JFIF" conventions, revision
-1.02.  A copy of the JFIF spec is available from:
-	Literature Department
-	C-Cube Microsystems, Inc.
-	1778 McCarthy Blvd.
-	Milpitas, CA 95035
-	phone (408) 944-6300,  fax (408) 944-6314
-A PostScript version of this document is available by FTP at
-ftp://ftp.uu.net/graphics/jpeg/jfif.ps.gz.  There is also a plain text
-version at ftp://ftp.uu.net/graphics/jpeg/jfif.txt.gz, but it is missing
-the figures.
-
-The TIFF 6.0 file format specification can be obtained by FTP from
-ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz.  The JPEG incorporation scheme
-found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems.
-IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6).
-Instead, we recommend the JPEG design proposed by TIFF Technical Note #2
-(Compression tag 7).  Copies of this Note can be obtained from ftp.sgi.com or
-from ftp://ftp.uu.net/graphics/jpeg/.  It is expected that the next revision
-of the TIFF spec will replace the 6.0 JPEG design with the Note's design.
-Although IJG's own code does not support TIFF/JPEG, the free libtiff library
-uses our library to implement TIFF/JPEG per the Note.  libtiff is available
-from ftp://ftp.sgi.com/graphics/tiff/.

-RELATED SOFTWARE
-================
-
-Numerous viewing and image manipulation programs now support JPEG.  (Quite a
-few of them use this library to do so.)  The JPEG FAQ described above lists
-some of the more popular free and shareware viewers, and tells where to
-obtain them on Internet.
-
-If you are on a Unix machine, we highly recommend Jef Poskanzer's free
-PBMPLUS software, which provides many useful operations on PPM-format image
-files.  In particular, it can convert PPM images to and from a wide range of
-other formats, thus making cjpeg/djpeg considerably more useful.  The latest
-version is distributed by the NetPBM group, and is available from numerous
-sites, notably ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/.
-Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software is;
-you are likely to have difficulty making it work on any non-Unix machine.
-
-A different free JPEG implementation, written by the PVRG group at Stanford,
-is available from ftp://havefun.stanford.edu/pub/jpeg/.  This program
-is designed for research and experimentation rather than production use;
-it is slower, harder to use, and less portable than the IJG code, but it
-is easier to read and modify.  Also, the PVRG code supports lossless JPEG,
-which we do not.  (On the other hand, it doesn't do progressive JPEG.)
-
-
-FILE FORMAT WARS
-================
-
-Some JPEG programs produce files that are not compatible with our library.
-The root of the problem is that the ISO JPEG committee failed to specify a
-concrete file format.  Some vendors "filled in the blanks" on their own,
-creating proprietary formats that no one else could read.  (For example, none
-of the early commercial JPEG implementations for the Macintosh were able to
-exchange compressed files.)
-
-The file format we have adopted is called JFIF (see REFERENCES).  This format
-has been agreed to by a number of major commercial JPEG vendors, and it has
-become the de facto standard.  JFIF is a minimal or "low end" representation.
-We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF
-Technical Note #2) for "high end" applications that need to record a lot of
-additional data about an image.  TIFF/JPEG is fairly new and not yet widely
-supported, unfortunately.
-
-The upcoming JPEG Part 3 standard defines a file format called SPIFF.
-SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should
-be able to read the most common variant of SPIFF.  SPIFF has some technical
-advantages over JFIF, but its major claim to fame is simply that it is an
-official standard rather than an informal one.  At this point it is unclear
-whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto
-standard.  IJG intends to support SPIFF once the standard is frozen, but we
-have not decided whether it should become our default output format or not.
-(In any case, our decoder will remain capable of reading JFIF indefinitely.)
-
-Various proprietary file formats incorporating JPEG compression also exist.
-We have little or no sympathy for the existence of these formats.  Indeed,
-one of the original reasons for developing this free software was to help
-force convergence on common, open format standards for JPEG files.  Don't
-use a proprietary file format!
-
-
-TO DO
-=====
-
-The major thrust for v7 will probably be improvement of visual quality.
-The current method for scaling the quantization tables is known not to be
-very good at low Q values.  We also intend to investigate block boundary
-smoothing, "poor man's variable quantization", and other means of improving
-quality-vs-file-size performance without sacrificing compatibility.
-
-In future versions, we are considering supporting some of the upcoming JPEG
-Part 3 extensions --- principally, variable quantization and the SPIFF file
-format.
-
-As always, speeding things up is of great interest.

+Mozilla JPEG Encoder Project
+============================
+
+mozjpeg is a fork of libjpeg-turbo that aims to speed up load times of web
+pages by reducing the size (and, by extension, the transmission time) of JPEG
+files.  It accomplishes this by enabling optimized Huffman trees and
+progressive entropy coding by default in the JPEG compressor, as well as
+splitting the spectrum of DCT coefficients into separate scans and using
+Trellis quantisation.
+
+Although it is based on libjpeg-turbo, mozjpeg is not intended to be a
+general-purpose or high-performance JPEG library.  Its performance is highly
+"asymmetric".  That is, the JPEG files it generates require much more time to
+compress than to decompress.  When the default settings are used, mozjpeg is
+considerably slower than libjpeg-turbo or even libjpeg at compressing images.
+Thus, it is not generally suitable for real-time compression.  It is best used
+as part of a web encoding workflow.
+
+
+libjpeg API Extensibility Framework
+===================================
+
+mozjpeg's implementation of the libjpeg API includes an extensibility framework
+that allows new features to be added without modifying the transparent libjpeg
+compress/decompress structures (which would break backward ABI compatibility.)
+Extension parameters are placed into the opaque jpeg_comp_master structure, and
+a set of accessor functions and globally unique tokens allows for
+getting/setting those parameters without directly accessing the structure.
+
+Currently, only the accessor functions necessary to support the mozjpeg
+extensions are implemented, but the framework can be easily extended in the
+future to accommodate additional simple parameter types, complex or
+multi-valued parameters, or decompressor extensions.
+
+
+The currently-implemented accessor functions are as follows:
+
+boolean jpeg_c_bool_param_supported (j_compress_ptr cinfo,
+                                     J_BOOLEAN_PARAM param)
+        Returns TRUE if the given boolean extension parameter is supported by
+        this implementation of the libjpeg API, or FALSE otherwise.
+
+void jpeg_c_set_bool_param (j_compress_ptr cinfo,
+                            J_BOOLEAN_PARAM param, boolean value);
+        Set the given boolean extension parameter to the given value (TRUE or
+        FALSE.)
+
+boolean jpeg_c_get_bool_param (j_compress_ptr cinfo, J_BOOLEAN_PARAM param)
+        Get the value of the given boolean extension parameter (TRUE or FALSE.)
+
+boolean jpeg_c_float_param_supported (j_compress_ptr cinfo,
+                                      J_FLOAT_PARAM param)
+        Returns TRUE if the given floating point extension parameter is
+        supported by this implementation of the libjpeg API, or FALSE
+        otherwise.
+
+void jpeg_c_set_float_param (j_compress_ptr cinfo, J_FLOAT_PARAM param,
+                             float value)
+        Set the given floating point extension parameter to the given value.
+
+float jpeg_c_get_float_param (j_compress_ptr cinfo, J_FLOAT_PARAM param);
+        Get the value of the given floating point extension parameter.
+
+boolean jpeg_c_int_param_supported (j_compress_ptr cinfo,
+                                    J_INT_PARAM param)
+        Returns TRUE if the given integer extension parameter is supported by
+        this implementation of the libjpeg API, or FALSE otherwise.
+
+void jpeg_c_set_int_param (j_compress_ptr cinfo, J_INT_PARAM param,
+                          int value)
+        Set the given integer extension parameter to the given value.
+
+int jpeg_c_get_int_param (j_compress_ptr cinfo, J_INT_PARAM param)
+        Get the value of the given integer extension parameter.
+
+
+Boolean Extension Parameters Supported by mozjpeg
+-------------------------------------------------
+
+* JBOOLEAN_OPTIMIZE_SCANS (default: TRUE)
+  Specifies whether scan parameters should be optimized.  Parameter
+  optimization is done as in jpgcrush. jpeg_simple_progression() should be called
+  after setting JBOOLEAN_OPTIMIZE_SCANS.
+  When disabling JBOOLEAN_OPTIMIZE_SCANS, cinfo.scan_info should additionally be
+  set to NULL to disable use of the progressive coding mode, if so desired.
+
+* JBOOLEAN_TRELLIS_QUANT (default: TRUE)
+  Specifies whether to apply trellis quantization.  For each 8x8 block, trellis
+  quantization determines the best tradeoff between rate and distortion.
+
+* JBOOLEAN_TRELLIS_QUANT_DC (default: TRUE)
+  Specifies whether to apply trellis quantization to DC coefficients.
+
+* JBOOLEAN_TRELLIS_EOB_OPT (default: FALSE)
+  Specifies whether to optimize runs of zero blocks in trellis quantization.
+  This is applicable only when JBOOLEAN_USE_SCANS_IN_TRELLIS is enabled.
+
+* JBOOLEAN_USE_LAMBDA_WEIGHT_TBL currently has no effect.
+
+* JBOOLEAN_USE_SCANS_IN_TRELLIS (default: FALSE)
+  Specifies whether multiple scans should be considered during trellis
+  quantization.
+
+* JBOOLEAN_TRELLIS_Q_OPT (default: FALSE)
+  Specifies whether to optimize the quantization table after trellis
+  quantization.  If enabled, then a revised quantization table is derived so
+  as to minimize the reconstruction error of the quantized coefficients.
+
+* JBOOLEAN_OVERSHOOT_DERINGING (default: TRUE)
+  Specifies whether overshooting is applied to samples with extreme values
+  (for example, 0 and 255 for 8-bit samples).  Overshooting may reduce ringing
+  artifacts from compression, in particular in areas where black text appears
+  on a white background.
+
+
+Floating Point Extension Parameters Supported by mozjpeg
+--------------------------------------------------------
+
+* JFLOAT_LAMBDA_LOG_SCALE1 (default: 14.75)
+  JFLOAT_LAMBDA_LOG_SCALE2 (default: 16.5)
+  These parameters specify the lambda value used in trellis quantization.  The
+  lambda value (Lagrange multiplier) in the
+    R + lambda * D
+  equation is derived from
+    lambda = 2^s1 / ((2^s2 + n) * q^2),
+  where s1 and s2 are the values of JFLOAT_LAMBDA_LOG_SCALE1 and
+  JFLOAT_LAMBDA_LOG_SCALE2, n is the average of the squared unquantized AC
+  coefficients within the current 8x8 block, and q is the quantization table
+  entry associated with the current coefficient frequency.  If
+  JFLOAT_LAMBDA_LOG_SCALE2 is 0, then an alternate form is used that does not
+  rely on n:
+    lambda = 2^(s1-12) / q^2.
+
+* JFLOAT_TRELLIS_DELTA_DC_WEIGHT (default: 0.0)
+  This parameter controls how distortion is calculated in DC trellis quantization
+  (enabled with JBOOLEAN_TRELLIS_QUANT_DC). It defines weighting between distortion
+  of the DC coefficient and distortion of the vertical gradient of DC coefficients.
+  The value of the parameter corresponds to the weight applied to the distortion
+  of the vertical gradient.
+
+
+Integer Extension Parameters Supported by mozjpeg
+-------------------------------------------------
+
+* JINT_COMPRESS_PROFILE (default: JCP_MAX_COMPRESSION)
+  Select a compression profile, which is a set of default parameters that will
+  achieve a desired compression goal.  This parameter controls the behavior of
+  the jpeg_set_defaults() function.  Thus, setting JINT_COMPRESS_PROFILE does
+  not cause any other parameters to be modified until jpeg_set_defaults() is
+  called.  The following compression profiles are supported:
+
+  - JCP_MAX_COMPRESSION (default)
+    Increase the compression ratio as much as possible, at the expense of
+    increased encoding time.  This enables progressive entropy coding and all
+    mozjpeg extensions.
+
+  - JCP_FASTEST
+    Use the libjpeg[-turbo] defaults (baseline entropy coding, no mozjpeg
+    extensions enabled.)
+
+* JINT_TRELLIS_FREQ_SPLIT (default: 8)
+  Specifies the position within the zigzag scan at which the split between
+  scans is positioned in the context of trellis quantization.
+  JBOOLEAN_USE_SCANS_IN_TRELLIS must be enabled for this parameter to have any
+  effect.
+
+* JINT_TRELLIS_NUM_LOOPS (default: 1)
+  Specifies the number of trellis quantization passes.  Huffman tables are
+  updated between passes.
+
+* JINT_BASE_QUANT_TBL_IDX (default: 3)
+  Specifies which quantization table set to use.  The following options are
+  available:
+  0 = Tables from JPEG Annex K
+  1 = Flat table
+  2 = Table tuned for MSSIM on Kodak image set
+  3 = Table from http://www.imagemagick.org/discourse-server/viewtopic.php?f=22&t=20333&p=98008#p98008
+  4 = Table tuned for PSNR-HVS-M on Kodak image set
+  5 = Table from:  Relevance of Human Vision to JPEG-DCT Compression
+      (1992) Klein, Silverstein and Carney
+  6 = Table from:  DCTune Perceptual Optimization of Compressed Dental X-Rays

+Background
+==========
+
+libjpeg-turbo is a JPEG image codec that uses SIMD instructions to accelerate
+baseline JPEG compression and decompression on x86, x86-64, Arm, PowerPC, and
+MIPS systems, as well as progressive JPEG compression on x86, x86-64, and Arm
+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.  libjpeg-turbo is an ISO/IEC and ITU-T
+reference implementation of the JPEG standard.
+

+
+Funding
+=======
+
+libjpeg-turbo is an independent open source project, but we rely on patronage
+and funded development in order to maintain that independence.  The easiest way
+to ensure that libjpeg-turbo remains community-focused and free of any one
+organization's agenda is to
+[sponsor our project through GitHub](https://github.com/sponsors/libjpeg-turbo).
+All sponsorship money goes directly toward funding the labor necessary to
+maintain libjpeg-turbo, support the user community, and implement bug fixes and
+strategically important features.

+
+
+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
+  <https://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 API: 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 API: Arithmetic coding**
+
+- **libjpeg API: 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.  Readers are invited to peruse the research at
+<https://libjpeg-turbo.org/About/SmartScale> and draw their 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 API: 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 API: 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 API: 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.
+
+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.  There are two exceptions:
+
+1. When decompressing a JPEG image that uses 4:4:0 chrominance subsampling, the
+outputs of libjpeg v6b and libjpeg-turbo can differ because libjpeg-turbo
+implements a "fancy" (smooth) 4:4:0 upsampling algorithm and libjpeg did not.
+
+2. When using the floating point DCT/IDCT, 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 accurate integer
+      IDCT.  The floating point DCT/IDCT algorithms are mainly a legacy
+      feature, and they do not produce significantly more accuracy than the
+      accurate 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 accurate 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.

+
+
+OVERVIEW
+========
+
+This package contains C software to implement JPEG image encoding, decoding,
+and transcoding.  JPEG (pronounced "jay-peg") is a standardized compression
+method for full-color and grayscale images.  JPEG's strong suit is compressing
+photographic images or other types of images that have smooth color and
+brightness transitions between neighboring pixels.  Images with sharp lines or
+other abrupt features may not compress well with JPEG, and a higher JPEG
+quality may have to be used to avoid visible compression artifacts with such
+images.
+
+JPEG is normally lossy, meaning that the output pixels are not necessarily
+identical to the input pixels.  However, on photographic content and other
+"smooth" images, very good compression ratios can be obtained with no visible
+compression artifacts, and extremely high compression ratios are possible if
+you are willing to sacrifice image quality (by reducing the "quality" setting
+in the compressor.)
+
+This software implements JPEG baseline, extended-sequential, progressive, and
+lossless compression processes.  Provision is made for supporting all variants
+of these processes, although some uncommon parameter settings aren't
+implemented yet.  We have made no provision for supporting the hierarchical
+processes defined in the standard.
+
+We provide a set of library routines for reading and writing JPEG image files,
+plus two sample applications "cjpeg" and "djpeg", which use the library to
+perform conversion between JPEG and some other popular image file formats.
+The library is intended to be reused in other applications.
+
+In order to support file conversion and viewing software, we have included
+considerable functionality beyond the bare JPEG coding/decoding capability;
+for example, the color quantization modules are not strictly part of JPEG
+decoding, but they are essential for output to colormapped file formats.  These
+extra functions can be compiled out of the library if not required for a
+particular application.
+
+We have also included "jpegtran", a utility for lossless transcoding between
+different JPEG processes, and "rdjpgcom" and "wrjpgcom", two simple
+applications for inserting and extracting textual comments in JFIF files.
+
+The emphasis in designing this software has been on achieving portability and
+flexibility, while also making it fast enough to be useful.  In particular,
+the software is not intended to be read as a tutorial on JPEG.  (See the
+REFERENCES section for introductory material.)  Rather, it is intended to
+be reliable, portable, industrial-strength code.  We do not claim to have
+achieved that goal in every aspect of the software, but we strive for it.
+
+We welcome the use of this software as a component of commercial products.
+No royalty is required, but we do ask for an acknowledgement in product
+documentation, as described under LEGAL ISSUES.

+REFERENCES
+==========
+
+We recommend reading one or more of these references before trying to
+understand the innards of the JPEG software.
+
+The best short technical introduction to the JPEG compression algorithm is
+        Wallace, Gregory K.  "The JPEG Still Picture Compression Standard",
+        Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.
+(Adjacent articles in that issue discuss MPEG motion picture compression,
+applications of JPEG, and related topics.)  If you don't have the CACM issue
+handy, a PDF file containing a revised version of Wallace's article is
+available at http://www.ijg.org/files/Wallace.JPEG.pdf.  The file (actually
+a preprint for an article that appeared in IEEE Trans. Consumer Electronics)
+omits the sample images that appeared in CACM, but it includes corrections
+and some added material.  Note: the Wallace article is copyright ACM and IEEE,
+and it may not be used for commercial purposes.
+
+A somewhat less technical, more leisurely introduction to JPEG can be found in
+"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by
+M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1.  This book provides
+good explanations and example C code for a multitude of compression methods
+including JPEG.  It is an excellent source if you are comfortable reading C
+code but don't know much about data compression in general.  The book's JPEG
+sample code is far from industrial-strength, but when you are ready to look
+at a full implementation, you've got one here...
+
+The best currently available description of JPEG is the textbook "JPEG Still
+Image Data Compression Standard" by William B. Pennebaker and Joan L.
+Mitchell, published by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1.
+Price US$59.95, 638 pp.  The book includes the complete text of the ISO JPEG
+standards (DIS 10918-1 and draft DIS 10918-2).
+
+The original JPEG standard is divided into two parts, Part 1 being the actual
+specification, while Part 2 covers compliance testing methods.  Part 1 is
+titled "Digital Compression and Coding of Continuous-tone Still Images,
+Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS
+10918-1, ITU-T T.81.  Part 2 is titled "Digital Compression and Coding of
+Continuous-tone Still Images, Part 2: Compliance testing" and has document
+numbers ISO/IEC IS 10918-2, ITU-T T.83.
+
+The JPEG standard does not specify all details of an interchangeable file
+format.  For the omitted details, we follow the "JFIF" conventions, revision
+1.02.  JFIF version 1 has been adopted as ISO/IEC 10918-5 (05/2013) and
+Recommendation ITU-T T.871 (05/2011): Information technology - Digital
+compression and coding of continuous-tone still images: JPEG File Interchange
+Format (JFIF).  It is available as a free download in PDF file format from
+https://www.iso.org/standard/54989.html and http://www.itu.int/rec/T-REC-T.871.
+A PDF file of the older JFIF 1.02 specification is available at
+http://www.w3.org/Graphics/JPEG/jfif3.pdf.
+
+The TIFF 6.0 file format specification can be obtained from
+http://mirrors.ctan.org/graphics/tiff/TIFF6.ps.gz.  The JPEG incorporation
+scheme found in the TIFF 6.0 spec of 3-June-92 has a number of serious
+problems.  IJG does not recommend use of the TIFF 6.0 design (TIFF Compression
+tag 6).  Instead, we recommend the JPEG design proposed by TIFF Technical Note
+#2 (Compression tag 7).  Copies of this Note can be obtained from
+http://www.ijg.org/files/.  It is expected that the next revision
+of the TIFF spec will replace the 6.0 JPEG design with the Note's design.
+Although IJG's own code does not support TIFF/JPEG, the free libtiff library
+uses our library to implement TIFF/JPEG per the Note.

+FILE FORMAT COMPATIBILITY
+=========================
+
+This software implements ITU T.81 | ISO/IEC 10918 with some extensions from
+ITU T.871 | ISO/IEC 10918-5 (JPEG File Interchange Format-- see REFERENCES).
+Informally, the term "JPEG image" or "JPEG file" most often refers to JFIF or
+a subset thereof, but there are other formats containing the name "JPEG" that
+are incompatible with the original JPEG standard or with JFIF (for instance,
+JPEG 2000 and JPEG XR).  This software therefore does not support these
+formats.  Indeed, one of the original reasons for developing this free software
+was to help force convergence on a common, interoperable format standard for
+JPEG files.
+
+JFIF is a minimal or "low end" representation.  TIFF/JPEG (TIFF revision 6.0 as
+modified by TIFF Technical Note #2) can be used for "high end" applications
+that need to record a lot of additional data about an image.

+Mozilla JPEG Encoder Project [![Build Status](https://ci.appveyor.com/api/projects/status/github/mozilla/mozjpeg?branch=master&svg=true)](https://ci.appveyor.com/project/kornel/mozjpeg-4ekrx)
+============================
+
+MozJPEG improves JPEG compression efficiency achieving higher visual quality and smaller file sizes at the same time. It is compatible with the JPEG standard, and the vast majority of the world's deployed JPEG decoders.
+
+MozJPEG is a patch for [libjpeg-turbo](https://github.com/libjpeg-turbo/libjpeg-turbo). **Please send pull requests to libjpeg-turbo** if the changes aren't specific to newly-added MozJPEG-only compression code. This project aims to keep differences with libjpeg-turbo minimal, so whenever possible, improvements and bug fixes should go there first.
+
+MozJPEG is compatible with the libjpeg API and ABI. It is intended to be a drop-in replacement for libjpeg. MozJPEG is a strict superset of libjpeg-turbo's functionality. All MozJPEG's improvements can be disabled at run time, and in that case it behaves exactly like libjpeg-turbo.
+
+MozJPEG is meant to be used as a library in graphics programs and image processing tools. We include a demo `cjpeg` command-line tool, but it's not intended for serious use. We encourage authors of graphics programs to use libjpeg's [C API](libjpeg.txt) and link with MozJPEG library instead.
+
+## Features
+
+* Progressive encoding with "jpegrescan" optimization. It can be applied to any JPEG file (with `jpegtran`) to losslessly reduce file size.
+* Trellis quantization. When converting other formats to JPEG it maximizes quality/filesize ratio.
+* Comes with new quantization table presets, e.g. tuned for high-resolution displays.
+* Fully compatible with all web browsers.
+* Can be seamlessly integrated into any program that uses the industry-standard libjpeg API. There's no need to write any MozJPEG-specific integration code.
+
+## Releases
+
+* [Latest release](https://github.com/mozilla/mozjpeg/releases/latest)
+* [Overview of 3.0 features](https://calendar.perfplanet.com/2014/mozjpeg-3-0/)
+* [Version 2.0 Announcement](https://blog.mozilla.org/research/2014/07/15/mozilla-advances-jpeg-encoding-with-mozjpeg-2-0/)
+* [Version 1.0 Announcement](https://blog.mozilla.org/research/2014/03/05/introducing-the-mozjpeg-project/)
+
+## Compiling
+
+See [BUILDING](BUILDING.md). MozJPEG is built exactly the same way as libjpeg-turbo, so if you need additional help please consult [libjpeg-turbo documentation](https://libjpeg-turbo.org/).

-		    GHOSTSCRIPT GENERAL PUBLIC LICENSE
-		    (Clarified 11 Feb 1988)
-
- Copyright (C) 1988 Richard M. Stallman
- Everyone is permitted to copy and distribute verbatim copies of this
- license, but changing it is not allowed.  You can also use this wording
- to make the terms for other programs.
-
-  The license agreements of most software companies keep you at the
-mercy of those companies.  By contrast, our general public license is
-intended to give everyone the right to share Ghostscript.  To make sure
-that you get the rights we want you to have, we need to make
-restrictions that forbid anyone to deny you these rights or to ask you
-to surrender the rights.  Hence this license agreement.
-
-  Specifically, we want to make sure that you have the right to give
-away copies of Ghostscript, that you receive source code or else can get
-it if you want it, that you can change Ghostscript or use pieces of it
-in new free programs, and that you know you can do these things.
-
-  To make sure that everyone has such rights, we have to forbid you to
-deprive anyone else of these rights.  For example, if you distribute
-copies of Ghostscript, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must tell them their rights.
-
-  Also, for our own protection, we must make certain that everyone finds
-out that there is no warranty for Ghostscript.  If Ghostscript is
-modified by someone else and passed on, we want its recipients to know
-that what they have is not what we distributed, so that any problems
-introduced by others will not reflect on our reputation.
-
-  Therefore we (Richard M. Stallman and the Free Software Foundation,
-Inc.) make the following terms which say what you must do to be allowed
-to distribute or change Ghostscript.
-
-
-			COPYING POLICIES
-
-  1. You may copy and distribute verbatim copies of Ghostscript source
-code as you receive it, in any medium, provided that you conspicuously
-and appropriately publish on each copy a valid copyright and license
-notice "Copyright (C) 1989 Aladdin Enterprises.  All rights reserved.
-Distributed by Free Software Foundation, Inc." (or with whatever year is
-appropriate); keep intact the notices on all files that refer to this
-License Agreement and to the absence of any warranty; and give any other
-recipients of the Ghostscript program a copy of this License Agreement
-along with the program.  You may charge a distribution fee for the
-physical act of transferring a copy.
-
-  2. You may modify your copy or copies of Ghostscript or any portion of
-it, and copy and distribute such modifications under the terms of
-Paragraph 1 above, provided that you also do the following:
-
-    a) cause the modified files to carry prominent notices stating
-    that you changed the files and the date of any change; and
-
-    b) cause the whole of any work that you distribute or publish,
-    that in whole or in part contains or is a derivative of Ghostscript
-    or any part thereof, to be licensed at no charge to all third
-    parties on terms identical to those contained in this License
-    Agreement (except that you may choose to grant more extensive
-    warranty protection to some or all third parties, at your option).
-
-    c) You may charge a distribution fee for the physical act of
-    transferring a copy, and you may at your option offer warranty
-    protection in exchange for a fee.
-
-Mere aggregation of another unrelated program with this program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other program under the scope of these terms.
-
-  3. You may copy and distribute Ghostscript (or a portion or derivative
-of it, under Paragraph 2) in object code or executable form under the
-terms of Paragraphs 1 and 2 above provided that you also do one of the

-/*
- * Usage:
-	ansi2knr input_file [output_file]
- * If no output_file is supplied, output goes to stdout.
- * There are no error messages.
- *
- * ansi2knr recognizes function definitions by seeing a non-keyword
- * identifier at the left margin, followed by a left parenthesis,
- * with a right parenthesis as the last character on the line,
- * and with a left brace as the first token on the following line
- * (ignoring possible intervening comments).
- * It will recognize a multi-line header provided that no intervening
- * line ends with a left or right brace or a semicolon.
- * These algorithms ignore whitespace and comments, except that
- * the function name must be the first thing on the line.
- * The following constructs will confuse it:
- *	- Any other construct that starts at the left margin and
- *	    follows the above syntax (such as a macro or function call).
- *	- Some macros that tinker with the syntax of the function header.
- */
-
-/*
- * The original and principal author of ansi2knr is L. Peter Deutsch
- * <ghost@aladdin.com>.  Other authors are noted in the change history
- * that follows (in reverse chronological order):
-	lpd 96-01-21 added code to cope with not HAVE_CONFIG_H and with
-		compilers that don't understand void, as suggested by
-		Tom Lane
-	lpd 96-01-15 changed to require that the first non-comment token
-		on the line following a function header be a left brace,
-		to reduce sensitivity to macros, as suggested by Tom Lane
-		<tgl@sss.pgh.pa.us>
-	lpd 95-06-22 removed #ifndefs whose sole purpose was to define
-		undefined preprocessor symbols as 0; changed all #ifdefs
-		for configuration symbols to #ifs
-	lpd 95-04-05 changed copyright notice to make it clear that
-		including ansi2knr in a program does not bring the entire
-		program under the GPL
-	lpd 94-12-18 added conditionals for systems where ctype macros
-		don't handle 8-bit characters properly, suggested by
-		Francois Pinard <pinard@iro.umontreal.ca>;
-		removed --varargs switch (this is now the default)
-	lpd 94-10-10 removed CONFIG_BROKETS conditional
-	lpd 94-07-16 added some conditionals to help GNU `configure',
-		suggested by Francois Pinard <pinard@iro.umontreal.ca>;
-		properly erase prototype args in function parameters,
-		contributed by Jim Avera <jima@netcom.com>;
-		correct error in writeblanks (it shouldn't erase EOLs)
-	lpd 89-xx-xx original version

+The \fB-quality\fR option has been extended in this version of \fBcjpeg\fR to
+support separate quality settings for luminance and chrominance (or, in
+general, separate settings for every quantization table slot.)  The principle
+is the same as chrominance subsampling:  since the human eye is more sensitive
+to spatial changes in brightness than spatial changes in color, the chrominance
+components can be quantized more than the luminance components without
+incurring any visible image quality loss.  However, unlike subsampling, this

+The \fB-quality\fR option accepts a comma-separated list of parameters, which

+given, this is used for both luminance and chrominance (slots 0 and 1,

+When the Independent JPEG Group's software was first released in 1991, the

+in minutes.  Thus, the \fBfast\fR integer DCT algorithm provided noticeable
+performance benefits.  On modern CPUs running libjpeg-turbo, however, the
+compression time for a 1-megapixel JPEG image is measured in milliseconds, and
+thus the performance benefits of the \fBfast\fR algorithm are much less
+noticeable.  On modern x86/x86-64 CPUs that support AVX2 instructions, the
+\fBfast\fR and \fBint\fR methods have similar performance.  On other types of
+CPUs, the \fBfast\fR method is generally about 5-15% faster than the \fBint\fR
+method.
+
+For quality levels of 90 and below, there should be little or no perceptible
+quality difference between the two algorithms.  For quality levels above 90,
+however, the difference between the \fBfast\fR and \fBint\fR methods becomes
+more pronounced.  With quality=97, for instance, the \fBfast\fR method incurs
+generally about a 1-3 dB loss in PSNR relative to the \fBint\fR method, but
+this can be larger for some images.  Do not use the \fBfast\fR method with
+quality levels above 97.  The algorithm often degenerates at quality=98 and
+above and can actually produce a more lossy image than if lower quality levels
+had been used.  Also, in libjpeg-turbo, the \fBfast\fR method is not fully

- * This program is intended to help you determine how to configure the JPEG

- * compile the program, run it, and it will produce a "jconfig.h" file for
- * your system.
- *
- * As a general rule, each time you try to compile this program,
- * pay attention only to the *first* error message you get from the compiler.
- * Many C compilers will issue lots of spurious error messages once they
- * have gotten confused.  Go to the line indicated in the first error message,
- * and read the comments preceding that line to see what to change.
- *
- * Almost all of the edits you may need to make to this program consist of
- * changing a line that reads "#define SOME_SYMBOL" to "#undef SOME_SYMBOL",
- * or vice versa.  This is called defining or undefining that symbol.

+#
+# .. _`GNU Coding Standards`: https://www.gnu.org/prep/standards/html_node/Directory-Variables.html
+#
+# Result Variables
+# ^^^^^^^^^^^^^^^^
+#
+# Inclusion of this module defines the following variables:
+#
+# ``CMAKE_INSTALL_<dir>``
+#
+#   Destination for files of a given type.  This value may be passed to
+#   the ``DESTINATION`` options of :command:`install` commands for the
+#   corresponding file type.
+#
+# ``CMAKE_INSTALL_FULL_<dir>``
+#
+#   The absolute path generated from the corresponding ``CMAKE_INSTALL_<dir>``
+#   value.  If the value is not already an absolute path, an absolute path
+#   is constructed typically by prepending the value of the
+#   :variable:`CMAKE_INSTALL_PREFIX` variable.  However, there are some
+#   `special cases`_ as documented below.
+#
+# where ``<dir>`` is one of:
+#
+# ``BINDIR``
+#   user executables (``bin``)
+# ``SBINDIR``
+#   system admin executables (``sbin``)
+# ``LIBEXECDIR``
+#   program executables (``libexec``)
+# ``SYSCONFDIR``
+#   read-only single-machine data (``etc``)
+# ``SHAREDSTATEDIR``
+#   modifiable architecture-independent data (``com``)
+# ``LOCALSTATEDIR``
+#   modifiable single-machine data (``var``)
+# ``LIBDIR``
+#   object code libraries (``lib`` or ``lib64``
+#   or ``lib/<multiarch-tuple>`` on Debian)
+# ``INCLUDEDIR``
+#   C header files (``include``)
+# ``OLDINCLUDEDIR``
+#   C header files for non-gcc (``/usr/include``)
+# ``DATAROOTDIR``
+#   read-only architecture-independent data root (``share``)
+# ``DATADIR``
+#   read-only architecture-independent data (``DATAROOTDIR``)
+# ``INFODIR``
+#   info documentation (``DATAROOTDIR/info``)
+# ``LOCALEDIR``
+#   locale-dependent data (``DATAROOTDIR/locale``)
+# ``MANDIR``
+#   man documentation (``DATAROOTDIR/man``)
+# ``DOCDIR``
+#   documentation root (``DATAROOTDIR/doc/PROJECT_NAME``)
+#
+# If the includer does not define a value the above-shown default will be
+# used and the value will appear in the cache for editing by the user.
+#
+# 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`_.

+# .. 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.

-ansi2knr does not transform method declarations (function pointers in

-	#else

-A similar solution is used for forward and external function declarations

-It seems there are some non-ANSI compilers in which the sizeof() operator

 Switches for advanced users:
 .TP
 .B \-dct int
-Use integer DCT method (default).
+Use accurate integer DCT method (default).
 .TP
 .B \-dct fast
-Use fast integer DCT (less accurate).
+Use less accurate integer DCT method [legacy feature].
+When the Independent JPEG Group's software was first released in 1991, the
+decompression time for a 1-megapixel JPEG image on a mainstream PC was measured
+in minutes.  Thus, the \fBfast\fR integer DCT algorithm provided noticeable
+performance benefits.  On modern CPUs running libjpeg-turbo, however, the
+decompression time for a 1-megapixel JPEG image is measured in milliseconds,
+and thus the performance benefits of the \fBfast\fR algorithm are much less
+noticeable.  On modern x86/x86-64 CPUs that support AVX2 instructions, the
+\fBfast\fR and \fBint\fR methods have similar performance.  On other types of
+CPUs, the \fBfast\fR method is generally about 5-15% faster than the \fBint\fR
+method.
+
+If the JPEG image was compressed using a quality level of 85 or below, then
+there should be little or no perceptible quality difference between the two
+algorithms.  When decompressing images that were compressed using quality
+levels above 85, however, the difference between the \fBfast\fR and \fBint\fR
+methods becomes more pronounced.  With images compressed using quality=97, for
+instance, the \fBfast\fR method incurs generally about a 4-6 dB loss in PSNR
+relative to the \fBint\fR method, but this can be larger for some images.  If
+you can avoid it, do not use the \fBfast\fR 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.
+Use floating-point DCT method [legacy feature].

+machines.
