+2.1.0
+=====
+
+### Significant changes relative to 2.1 beta1
+
+1. Fixed a regression introduced by 2.1 beta1[6(b)] whereby attempting to
+decompress certain progressive JPEG images with one or more component planes of
+width 8 or less caused a buffer overrun.
+
+2. Fixed a regression introduced by 2.1 beta1[6(b)] whereby attempting to
+decompress a specially-crafted malformed progressive JPEG image caused the
+block smoothing algorithm to read from uninitialized memory.
+
+3. Fixed an issue in the Arm Neon SIMD Huffman encoders that caused the
+encoders to generate incorrect results when using the Clang compiler with
+Visual Studio.
+
+4. Fixed a floating point exception (CVE-2021-20205) that occurred when
+attempting to compress a specially-crafted malformed GIF image with a specified
+image width of 0 using cjpeg.
+
+5. Fixed a regression introduced by 2.0 beta1[15] whereby attempting to
+generate a progressive JPEG image on an SSE2-capable CPU using a scan script
+containing one or more scans with lengths divisible by 32 and non-zero
+successive approximation low bit positions would, under certain circumstances,
+result in an error ("Missing Huffman code table entry") and an invalid JPEG
+image.
+
+6. Introduced a new flag (`TJFLAG_LIMITSCANS` in the TurboJPEG C API and
+`TJ.FLAG_LIMIT_SCANS` in the TurboJPEG Java API) and a corresponding TJBench
+command-line argument (`-limitscans`) that causes the TurboJPEG decompression
+and transform functions/operations to return/throw an error if a progressive
+JPEG image contains an unreasonably large number of scans.  This allows
+applications that use the TurboJPEG API to guard against an exploit of the
+progressive JPEG format described in the report
+["Two Issues with the JPEG Standard"](https://libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf).
+
+7. The PPM reader now throws an error, rather than segfaulting (due to a buffer
+overrun) or generating incorrect pixels, if an application attempts to use the
+`tjLoadImage()` function to load a 16-bit binary PPM file (a binary PPM file
+with a maximum value greater than 255) into a grayscale image buffer or to load
+a 16-bit binary PGM file into an RGB image buffer.
+
+8. Fixed an issue in the PPM reader that caused incorrect pixels to be
+generated when using the `tjLoadImage()` function to load a 16-bit binary PPM
+file into an extended RGB image buffer.
+
+9. Fixed an issue whereby, if a JPEG buffer was automatically re-allocated by
+one of the TurboJPEG compression or transform functions and an error
+subsequently occurred during compression or transformation, the JPEG buffer
+pointer passed by the application was not updated when the function returned.
+
+
+2.0.90 (2.1 beta1)
+==================
+
+### Significant changes relative to 2.0.6:
+
+1. The build system, x86-64 SIMD extensions, and accelerated Huffman codec now
+support the x32 ABI on Linux, which allows for using x86-64 instructions with
+32-bit pointers.  The x32 ABI is generally enabled by adding `-mx32` to the
+compiler flags.
+
+     Caveats:
+     - CMake 3.9.0 or later is required in order for the build system to
+automatically detect an x32 build.
+     - Java does not support the x32 ABI, and thus the TurboJPEG Java API will
+automatically be disabled with x32 builds.
+
+2. Added Loongson MMI SIMD implementations of the RGB-to-grayscale, 4:2:2 fancy
+chroma upsampling, 4:2:2 and 4:2:0 merged chroma upsampling/color conversion,
+and fast integer DCT/IDCT algorithms.  Relative to libjpeg-turbo 2.0.x, this
+speeds up:
+
+     - the compression of RGB source images into grayscale JPEG images by
+approximately 20%
+     - the decompression of 4:2:2 JPEG images by approximately 40-60% when
+using fancy upsampling
+     - the decompression of 4:2:2 and 4:2:0 JPEG images by approximately
+15-20% when using merged upsampling
+     - the compression of RGB source images by approximately 30-45% when using
+the fast integer DCT
+     - the decompression of JPEG images into RGB destination images by
+approximately 2x when using the fast integer IDCT
+
+    The overall decompression speedup for RGB images is now approximately
+2.3-3.7x (compared to 2-3.5x with libjpeg-turbo 2.0.x.)
+
+3. 32-bit (Armv7 or Armv7s) iOS builds of libjpeg-turbo are no longer
+supported, and the libjpeg-turbo build system can no longer be used to package
+such builds.  32-bit iOS apps cannot run in iOS 11 and later, and the App Store
+no longer allows them.
+
+4. 32-bit (i386) OS X/macOS builds of libjpeg-turbo are no longer supported,
+and the libjpeg-turbo build system can no longer be used to package such
+builds.  32-bit Mac applications cannot run in macOS 10.15 "Catalina" and
+later, and the App Store no longer allows them.
+
+5. The SSE2 (x86 SIMD) and C Huffman encoding algorithms have been
+significantly optimized, resulting in a measured average overall compression
+speedup of 12-28% for 64-bit code and 22-52% for 32-bit code on various Intel
+and AMD CPUs, as well as a measured average overall compression speedup of
+0-23% on platforms that do not have a SIMD-accelerated Huffman encoding
+implementation.
+
+6. The block smoothing algorithm that is applied by default when decompressing
+progressive Huffman-encoded JPEG images has been improved in the following
+ways:
+
+     - The algorithm is now more fault-tolerant.  Previously, if a particular
+scan was incomplete, then the smoothing parameters for the incomplete scan
+would be applied to the entire output image, including the parts of the image
+that were generated by the prior (complete) scan.  Visually, this had the
+effect of removing block smoothing from lower-frequency scans if they were
+followed by an incomplete higher-frequency scan.  libjpeg-turbo now applies
+block smoothing parameters to each iMCU row based on which scan generated the
+pixels in that row, rather than always using the block smoothing parameters for
+the most recent scan.
+     - When applying block smoothing to DC scans, a Gaussian-like kernel with a
+5x5 window is used to reduce the "blocky" appearance.
+
+7. Added SIMD acceleration for progressive Huffman encoding on Arm platforms.
+This speeds up the compression of full-color progressive JPEGs by about 30-40%
+on average (relative to libjpeg-turbo 2.0.x) when using modern Arm CPUs.
+
+8. Added configure-time and run-time auto-detection of Loongson MMI SIMD
+instructions, so that the Loongson MMI SIMD extensions can be included in any
+MIPS64 libjpeg-turbo build.
+
+9. Added fault tolerance features to djpeg and jpegtran, mainly to demonstrate
+methods by which applications can guard against the exploits of the JPEG format
+described in the report
+["Two Issues with the JPEG Standard"](https://libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf).
+
+     - Both programs now accept a `-maxscans` argument, which can be used to
+limit the number of allowable scans in the input file.
+     - Both programs now accept a `-strict` argument, which can be used to
+treat all warnings as fatal.
+
+10. CMake package config files are now included for both the libjpeg and
+TurboJPEG API libraries.  This facilitates using libjpeg-turbo with CMake's
+`find_package()` function.  For example:
+
+        find_package(libjpeg-turbo CONFIG REQUIRED)
+
+        add_executable(libjpeg_program libjpeg_program.c)
+        target_link_libraries(libjpeg_program PUBLIC libjpeg-turbo::jpeg)
+
+        add_executable(libjpeg_program_static libjpeg_program.c)
+        target_link_libraries(libjpeg_program_static PUBLIC
+          libjpeg-turbo::jpeg-static)
+
+        add_executable(turbojpeg_program turbojpeg_program.c)
+        target_link_libraries(turbojpeg_program PUBLIC
+          libjpeg-turbo::turbojpeg)
+
+        add_executable(turbojpeg_program_static turbojpeg_program.c)
+        target_link_libraries(turbojpeg_program_static PUBLIC
+          libjpeg-turbo::turbojpeg-static)
+
+11. Since the Unisys LZW patent has long expired, cjpeg and djpeg can now
+read/write both LZW-compressed and uncompressed GIF files (feature ported from
+jpeg-6a and jpeg-9d.)
+
+12. jpegtran now includes the `-wipe` and `-drop` options from jpeg-9a and
+jpeg-9d, as well as the ability to expand the image size using the `-crop`
+option.  Refer to jpegtran.1 or usage.txt for more details.
+
+13. Added a complete intrinsics implementation of the Arm Neon SIMD extensions,
+thus providing SIMD acceleration on Arm platforms for all of the algorithms
+that are SIMD-accelerated on x86 platforms.  This new implementation is
+significantly faster in some cases than the old GAS implementation--
+depending on the algorithms used, the type of CPU core, and the compiler.  GCC,
+as of this writing, does not provide a full or optimal set of Neon intrinsics,
+so for performance reasons, the default when building libjpeg-turbo with GCC is
+to continue using the GAS implementation of the following algorithms:
+
+     - 32-bit RGB-to-YCbCr color conversion
+     - 32-bit fast and accurate inverse DCT
+     - 64-bit RGB-to-YCbCr and YCbCr-to-RGB color conversion
+     - 64-bit accurate forward and inverse DCT
+     - 64-bit Huffman encoding
+
+    A new CMake variable (`NEON_INTRINSICS`) can be used to override this
+default.
+
+    Since the new intrinsics implementation includes SIMD acceleration
+for merged upsampling/color conversion, 1.5.1[5] is no longer necessary and has
+been reverted.
+
+14. The Arm Neon SIMD extensions can now be built using Visual Studio.
+
+15. The build system can now be used to generate a universal x86-64 + Armv8
+libjpeg-turbo SDK package for both iOS and macOS.
+
+
+2.0.6
+=====
+
+### Significant changes relative to 2.0.5:
+
+1. Fixed "using JNI after critical get" errors that occurred on Android
+platforms when using any of the YUV encoding/compression/decompression/decoding
+methods in the TurboJPEG Java API.
+
+2. Fixed or worked around multiple issues with `jpeg_skip_scanlines()`:
+
+     - Fixed segfaults or "Corrupt JPEG data: premature end of data segment"
+errors in `jpeg_skip_scanlines()` that occurred when decompressing 4:2:2 or
+4:2:0 JPEG images using merged (non-fancy) upsampling/color conversion (that
+is, when setting `cinfo.do_fancy_upsampling` to `FALSE`.)  2.0.0[6] was a
+similar fix, but it did not cover all cases.
+     - `jpeg_skip_scanlines()` now throws an error if two-pass color
+quantization is enabled.  Two-pass color quantization never worked properly
+with `jpeg_skip_scanlines()`, and the issues could not readily be fixed.
+     - Fixed an issue whereby `jpeg_skip_scanlines()` always returned 0 when
+skipping past the end of an image.
+
+3. The Arm 64-bit (Armv8) Neon SIMD extensions can now be built using MinGW
+toolchains targetting Arm64 (AArch64) Windows binaries.
+
+4. Fixed unexpected visual artifacts that occurred when using
+`jpeg_crop_scanline()` and interblock smoothing while decompressing only the DC
+scan of a progressive JPEG image.
+
+5. Fixed an issue whereby libjpeg-turbo would not build if 12-bit-per-component
+JPEG support (`WITH_12BIT`) was enabled along with libjpeg v7 or libjpeg v8
+API/ABI emulation (`WITH_JPEG7` or `WITH_JPEG8`.)
+
+
+2.0.5
+=====
+
+### Significant changes relative to 2.0.4:
+
+1. Worked around issues in the MIPS DSPr2 SIMD extensions that caused failures
+in the libjpeg-turbo regression tests.  Specifically, the
+`jsimd_h2v1_downsample_dspr2()` and `jsimd_h2v2_downsample_dspr2()` functions
+in the MIPS DSPr2 SIMD extensions are now disabled until/unless they can be
+fixed, and other functions that are incompatible with big endian MIPS CPUs are
+disabled when building libjpeg-turbo for such CPUs.
+
+2. Fixed an oversight in the `TJCompressor.compress(int)` method in the
+TurboJPEG Java API that caused an error ("java.lang.IllegalStateException: No
+source image is associated with this instance") when attempting to use that
+method to compress a YUV image.
+
+3. Fixed an issue (CVE-2020-13790) in the PPM reader that caused a buffer
+overrun in cjpeg, TJBench, or the `tjLoadImage()` function if one of the values
+in a binary PPM/PGM input file exceeded the maximum value defined in the file's
+header and that maximum value was less than 255.  libjpeg-turbo 1.5.0 already
+included a similar fix for binary PPM/PGM files with maximum values greater
+than 255.
+
+4. The TurboJPEG API library's global error handler, which is used in functions
+such as `tjBufSize()` and `tjLoadImage()` that do not require a TurboJPEG
+instance handle, is now thread-safe on platforms that support thread-local
+storage.
+
+
+2.0.4
+=====
+
+### Significant changes relative to 2.0.3:
+
+1. Fixed a regression in the Windows packaging system (introduced by
+2.0 beta1[2]) whereby, if both the 64-bit libjpeg-turbo SDK for GCC and the
+64-bit libjpeg-turbo SDK for Visual C++ were installed on the same system, only
+one of them could be uninstalled.
+
+2. Fixed a signed integer overflow and subsequent segfault that occurred when
+attempting to decompress images with more than 715827882 pixels using the
+64-bit C version of TJBench.
+
+3. Fixed out-of-bounds write in `tjDecompressToYUV2()` and
+`tjDecompressToYUVPlanes()` (sometimes manifesting as a double free) that
+occurred when attempting to decompress grayscale JPEG images that were
+compressed with a sampling factor other than 1 (for instance, with
+`cjpeg -grayscale -sample 2x2`).
+
+4. Fixed a regression introduced by 2.0.2[5] that caused the TurboJPEG API to
+incorrectly identify some JPEG images with unusual sampling factors as 4:4:4
+JPEG images.  This was known to cause a buffer overflow when attempting to
+decompress some such images using `tjDecompressToYUV2()` or
+`tjDecompressToYUVPlanes()`.
+
+5. Fixed an issue, detected by ASan, whereby attempting to losslessly transform
+a specially-crafted malformed JPEG image containing an extremely-high-frequency
+coefficient block (junk image data that could never be generated by a
+legitimate JPEG compressor) could cause the Huffman encoder's local buffer to
+be overrun. (Refer to 1.4.0[9] and 1.4beta1[15].)  Given that the buffer
+overrun was fully contained within the stack and did not cause a segfault or
+other user-visible errant behavior, and given that the lossless transformer
+(unlike the decompressor) is not generally exposed to arbitrary data exploits,
+this issue did not likely pose a security risk.
+
+6. The Arm 64-bit (Armv8) Neon SIMD assembly code now stores constants in a
+separate read-only data section rather than in the text section, to support
+execute-only memory layouts.
+

+* A build file (BUILD.gn)

+* A codereview.settings file
+* Patched header files used by Chromium

+  do not generate performant code from intrinsics):
+  simd/arm/aarch32/jsimd_neon.S, simd/arm/aarch64/jsimd_neon.S.
+
+This libjpeg-turbo can replace our libjpeg-6b without any modifications in the
+Chromium code.
+
+Same as our copy of libjpeg-6b, this libjpeg-turbo also added a new file
+jpeglibmangler.h and included it from jpeglib.h that changes the names of all
+externally visible functions to chromium_* so that we can avoid conflicts that
+arise when system libraries attempt to use our libjpeg. Also, we applied the
+following changes which are not merged to upstream:
+
+* Configuration files jconfig.h, jconfigint.h and neon-compat.h were generated
+  and then altered manually to be compatible on all of Chromium's platforms.
+  http://crbug.com/608347
+* Fix static const data duplication of jpeg_nbits_table. A unique copy
+  was in the jchuff.obj and jcphuff.obj resulting in an added 65k in
+  .rdata in chrome.dll and chrome_child.dll.  Declaring extern const
+  in the header instead of static const and moving the definition to
+  a new .c file fixes this so only one copy is referenced. Also added
+  extern wrappers around usage in asm files. The jpeg_nbits_table.inc
+  file was also deleted. It was also necessary to give this table hidden
+  visibility to avoid invalid relocations (ignored by ld but rejected by
+  lld) arising from attempts to reference the table from assembler on
+  32-bit x86. This only affects shared libraries, but that's important
+  for downstream Android builds.
+* Patches to enable running the upstream unit tests through GTest.
+  The upstream unit tests are defined here under the section 'TESTS':
+  https://github.com/libjpeg-turbo/libjpeg-turbo/blob/master/CMakeLists.txt
+  These changes are tracked by Chromium issue: https://crbug.com/993876

+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

-# GNUInstallDirs
-# --------------
-#
-# Define GNU standard installation directories
-#
-# Provides install directory variables as defined by the
-# `GNU Coding Standards`_.
-#
-# .. _`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`_.
-#
-# .. _`Filesystem Hierarchy Standard`: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
-#
-# Macros
-# ^^^^^^
-#
-# .. command:: GNUInstallDirs_get_absolute_install_dir
-#
-#   ::
-#
-#     GNUInstallDirs_get_absolute_install_dir(absvar var)
-#
-#   Set the given variable ``absvar`` to the absolute path contained
-#   within the variable ``var``.  This is to allow the computation of an
-#   absolute path, accounting for all the special cases documented
-#   above.  While this macro is used to compute the various
-#   ``CMAKE_INSTALL_FULL_<dir>`` variables, it is exposed publicly to
-#   allow users who create additional path variables to also compute
-#   absolute paths where necessary, using the same logic.

 .B \-dct fast
-Use fast integer DCT (less accurate).
-In libjpeg-turbo, the fast method is generally about 5-15% faster than the int
-method when using the x86/x86-64 SIMD extensions (results may vary with other
-SIMD implementations, or when using libjpeg-turbo without SIMD extensions.)  If
-the JPEG image was compressed using a quality level of 85 or below, then there
-should be little or no perceptible difference between the two algorithms.  When
-decompressing images that were compressed using quality levels above 85,
-however, the difference between the fast and int methods becomes more
-pronounced.  With images compressed using quality=97, for instance, the fast
-method incurs generally about a 4-6 dB loss (in PSNR) relative to the int
-method, but this can be larger for some images.  If you can avoid it, do not
-use the fast method when decompressing images that were compressed using
-quality levels above 97.  The algorithm often degenerates for such images and
-can actually produce a more lossy output image than if the JPEG image had been
-compressed using lower quality levels.
+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.

-<p>TurboJPEG API. </p>
-<p>This API provides an interface for generating, decoding, and transforming planar YUV and JPEG images in memory.</p>
-<p><a class="anchor" id="YUVnotes"></a></p>
-<h2>YUV Image Format Notes</h2>
-<p>Technically, the JPEG format uses the YCbCr colorspace (which is technically not a colorspace but a color transform), but per the convention of the digital video community, the TurboJPEG API uses "YUV" to refer to an image format consisting of Y, Cb, and Cr image planes.</p>
-<p>Each plane is simply a 2D array of bytes, each byte representing the value of one of the components (Y, Cb, or Cr) at a particular location in the image. The width and height of each plane are determined by the image width, height, and level of chrominance subsampling. The luminance plane width is the image width padded to the nearest multiple of the horizontal subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of 4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane height is the image height padded to the nearest multiple of the vertical subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4 or grayscale.) This is irrespective of any additional padding that may be specified as an argument to the various YUV functions. The chrominance plane width is equal to the luminance plane width divided by the horizontal subsampling factor, and the chrominance plane height is equal to the luminance plane height divided by the vertical subsampling factor.</p>
-<p>For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is used, then the luminance plane would be 36 x 35 bytes, and each of the chrominance planes would be 18 x 35 bytes. If you specify a line padding of 4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and each of the chrominance planes would be 20 x 35 bytes. </p>

-<p>YCbCr is not an absolute colorspace but rather a mathematical transformation of RGB designed solely for storage and transmission. YCbCr images must be converted to RGB before they can actually be displayed. In the YCbCr colorspace, the Y (luminance) component represents the black &amp; white portion of the original image, and the Cb and Cr (chrominance) components represent the color portion of the original image. Originally, the analog equivalent of this transformation allowed the same signal to drive both black &amp; white and color televisions, but JPEG images use YCbCr primarily because it allows the color data to be optionally subsampled for the purposes of reducing bandwidth or disk space. YCbCr is the most common JPEG colorspace, and YCbCr JPEG images can be compressed from and decompressed to any of the extended RGB pixel formats or grayscale, or they can be decompressed to YUV planar images. </p>

-<p>Unlike RGB, which is an additive color model used primarily for display, CMYK (Cyan/Magenta/Yellow/Key) is a subtractive color model used primarily for printing. In the CMYK color model, the value of each color component typically corresponds to an amount of cyan, magenta, yellow, or black ink that is applied to a white background. In order to convert between CMYK and RGB, it is necessary to use a color management system (CMS.) A CMS will attempt to map colors within the printer's gamut to perceptually similar colors in the display's gamut and vice versa, but the mapping is typically not 1:1 or reversible, nor can it be defined with a simple formula. Thus, such a conversion is out of scope for a codec library. However, the TurboJPEG API allows for compressing CMYK pixels into a YCCK JPEG image (see <a class="el" href="group___turbo_j_p_e_g.html#gga4f83ad3368e0e29d1957be0efa7c3720a53839e0fe867b76b58d16b0a1a7c598e" title="YCCK colorspace.">TJCS_YCCK</a>) and decompressing YCCK JPEG images into CMYK pixels. </p>

-<p>The maximum size of the buffer (in bytes) required to hold a JPEG image with the given parameters. </p>
-<p>The number of bytes returned by this function is larger than the size of the uncompressed source image. The reason for this is that the JPEG format uses 16-bit coefficients, and it is thus possible for a very high-quality JPEG image with very high-frequency content to expand rather than compress when converted to the JPEG format. Such images represent a very rare corner case, but since there is no way to predict the size of a JPEG image prior to compression, the corner case has to be handled.</p>

-<p>Losslessly transform a JPEG image into another JPEG image. </p>
-<p>Lossless transforms work by moving the raw DCT coefficients from one JPEG image structure to another without altering the values of the coefficients. While this is typically faster than decompressing the image, transforming it, and re-compressing it, lossless transforms are not free. Each lossless transform requires reading and performing Huffman decoding on all of the coefficients in the source image, regardless of the size of the destination image. Thus, this function provides a means of generating multiple transformed images from the same source or applying multiple transformations simultaneously, in order to eliminate the need to read the source coefficients multiple times.</p>

- * This file illustrates how to use the IJG code as a subroutine library
- * to read or write JPEG image files.  You should look at this code in
- * conjunction with the documentation file libjpeg.txt.
- *
- * This code will not do anything useful as-is, but it may be helpful as a
- * skeleton for constructing routines that call the JPEG library.
- *
- * We present these routines in the same coding style used in the JPEG code
- * (ANSI function definitions, etc); but you are of course free to code your
- * routines in a different style if you prefer.
- */

-/* This example was part of the original libjpeg documentation and has been
- * unchanged since 1994.  It is, as described in libjpeg.txt, "heavily
- * commented skeleton code for calling the JPEG library."  It is not meant to
- * be compiled as a standalone program, since it has no main() function and
- * does not compress from/decompress to a real image buffer (corollary:
- * put_scanline_someplace() is not a real function.)  First-time users of
- * libjpeg-turbo would be better served by looking at tjexample.c, which uses
- * the more straightforward TurboJPEG API, or at cjpeg.c and djpeg.c, which are
- * examples of libjpeg API usage that can be (and are) compiled into standalone
- * programs.  Note that this example, as well as the examples in cjpeg.c and
- * djpeg.c, interleave disk I/O with JPEG compression/decompression, so none of
- * these examples is suitable for benchmarking purposes.

- * with a fatal error).  Partial writes can only occur if you use a data
- * destination module that can demand suspension of the compressor.
- * (If you don't know what that's for, you don't need it.)
- *
- * If the compressor requires full-image buffers (for entropy-coding
- * optimization or a multi-scan JPEG file), it will create temporary
- * files for anything that doesn't fit within the maximum-memory setting.
- * (Note that temp files are NOT needed if you use the default parameters.)
- * On some systems you may need to set up a signal handler to ensure that
- * temporary files are deleted if the program is interrupted.  See libjpeg.txt.
- *
- * Scanlines MUST be supplied in top-to-bottom order if you want your JPEG
- * files to be compatible with everyone else's.  If you cannot readily read
- * your data in that order, you'll need an intermediate array to hold the

- *   (a) how to modify the JPEG library's standard error-reporting behavior;
- *   (b) how to allocate workspace using the library's memory manager.
- *
- * Just to make this example a little different from the first one, we'll

- * ERROR HANDLING:
- *
- * The JPEG library's standard error handler (jerror.c) is divided into
- * several "methods" which you can override individually.  This lets you
- * adjust the behavior without duplicating a lot of code, which you might
- * have to update with each future release.
- *
- * Our example here shows how to override the "error_exit" method so that
- * control is returned to the library's caller when a fatal error occurs,
- * rather than calling exit() as the standard error_exit method does.
- *
- * We use C's setjmp/longjmp facility to return control.  This means that the
- * routine which calls the JPEG library must first execute a setjmp() call to
- * establish the return point.  We want the replacement error_exit to do a
- * longjmp().  But we need to make the setjmp buffer accessible to the
- * error_exit routine.  To do this, we make a private extension of the
- * standard JPEG error handler object.  (If we were using C++, we'd say we
- * were making a subclass of the regular error handler.)
- *
- * Here's the extended error handler struct:

-TurboJPEG Java Wrapper
-======================
-
-The TurboJPEG shared library can optionally be built with a Java Native
-Interface wrapper, which allows the library to be loaded and used directly from
-Java applications.  The Java front end for this is defined in several classes
-located under org/libjpegturbo/turbojpeg.  The source code for these Java
-classes is licensed under a BSD-style license, so the files can be incorporated
-directly into both open source and proprietary projects without restriction.  A
-Java archive (JAR) file containing these classes is also shipped with the
-"official" distribution packages of libjpeg-turbo.
-
-TJExample.java, which should also be located in the same directory as this
-README file, demonstrates how to use the TurboJPEG Java API to compress and
-decompress JPEG images in memory.
-
-
-Performance Pitfalls
---------------------
-
-The TurboJPEG Java API defines several convenience methods that can allocate
-image buffers or instantiate classes to hold the result of compress,
-decompress, or transform operations.  However, if you use these methods, then
-be mindful of the amount of new data you are creating on the heap.  It may be
-necessary to manually invoke the garbage collector to prevent heap exhaustion
-or to prevent performance degradation.  Background garbage collection can kill
-performance, particularly in a multi-threaded environment (Java pauses all
-threads when the GC runs.)
-
-The TurboJPEG Java API always gives you the option of pre-allocating your own
-source and destination buffers, which allows you to re-use those buffers for
-compressing/decompressing multiple images.  If the image sequence you are
-compressing or decompressing consists of images of the same size, then
-pre-allocating the buffers is recommended.
-
-
-Installation Directory
-----------------------
-
-The TurboJPEG Java Wrapper will look for the TurboJPEG JNI library
-(libturbojpeg.so, libturbojpeg.jnilib, or turbojpeg.dll) in the system library
-paths or in any paths specified in LD_LIBRARY_PATH (Un*x), DYLD_LIBRARY_PATH
-(Mac), or PATH (Windows.)  Failing this, on Un*x and Mac systems, the wrapper
-will look for the JNI library under the library directory configured when
-libjpeg-turbo was built.  If that library directory is
-/opt/libjpeg-turbo/lib32, then /opt/libjpeg-turbo/lib64 is also searched, and
-vice versa.
-
-If you installed the JNI library into another directory, then you will need
-to pass an argument of -Djava.library.path={path_to_JNI_library} to java, or
-manipulate LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, or PATH to include the directory
-containing the JNI library.

-<h1 class="title">How This API Document Is Organized</h1>
-<div class="subTitle">This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.</div>
-</div>
-<div class="contentContainer">
-<ul class="blockList">
-<li class="blockList">
-<h2>Package</h2>
-<p>Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain six categories:</p>
-<ul>
-<li>Interfaces (italic)</li>
-<li>Classes</li>
-<li>Enums</li>
-<li>Exceptions</li>
-<li>Errors</li>
-<li>Annotation Types</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Class/Interface</h2>
-<p>Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:</p>
-<ul>
-<li>Class inheritance diagram</li>
-<li>Direct Subclasses</li>
-<li>All Known Subinterfaces</li>
-<li>All Known Implementing Classes</li>
-<li>Class/interface declaration</li>
-<li>Class/interface description</li>
-</ul>
-<ul>
-<li>Nested Class Summary</li>
-<li>Field Summary</li>
-<li>Constructor Summary</li>
-<li>Method Summary</li>
-</ul>
-<ul>
-<li>Field Detail</li>
-<li>Constructor Detail</li>
-<li>Method Detail</li>
-</ul>
-<p>Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</p>
-</li>
-<li class="blockList">
-<h2>Annotation Type</h2>
-<p>Each annotation type has its own separate page with the following sections:</p>
-<ul>
-<li>Annotation Type declaration</li>
-<li>Annotation Type description</li>
-<li>Required Element Summary</li>
-<li>Optional Element Summary</li>
-<li>Element Detail</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Enum</h2>
-<p>Each enum has its own separate page with the following sections:</p>
-<ul>
-<li>Enum declaration</li>
-<li>Enum description</li>
-<li>Enum Constant Summary</li>
-<li>Enum Constant Detail</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Tree (Class Hierarchy)</h2>
-<p>There is a <a href="overview-tree.html">Class Hierarchy</a> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.</p>
-<ul>
-<li>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.</li>
-<li>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</li>
-</ul>
-</li>
-<li class="blockList">
-<h2>Deprecated API</h2>
-<p>The <a href="deprecated-list.html">Deprecated API</a> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</p>
-</li>
-<li class="blockList">
-<h2>Index</h2>
-<p>The <a href="index-all.html">Index</a> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</p>
-</li>
-<li class="blockList">
-<h2>Prev/Next</h2>
-<p>These links take you to the next or previous class, interface, package, or related page.</p>
-</li>
-<li class="blockList">
-<h2>Frames/No Frames</h2>
-<p>These links show and hide the HTML frames.  All pages are available with or without frames.</p>
-</li>
-<li class="blockList">
-<h2>All Classes</h2>
-<p>The <a href="allclasses-noframe.html">All Classes</a> link shows all classes and interfaces except non-static nested types.</p>
-</li>
-<li class="blockList">
-<h2>Serialized Form</h2>
-<p>Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.</p>
-</li>
-<li class="blockList">
-<h2>Constant Field Values</h2>
-<p>The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.</p>
-</li>
-</ul>
-<em>This help file applies to API documentation generated using the standard doclet.</em></div>

- primarily for display, CMYK (Cyan/Magenta/Yellow/Key) is a subtractive
- color model used primarily for printing.  In the CMYK color model, the
- value of each color component typically corresponds to an amount of cyan,
- magenta, yellow, or black ink that is applied to a white background.  In
- order to convert between CMYK and RGB, it is necessary to use a color
- management system (CMS.)  A CMS will attempt to map colors within the
- printer's gamut to perceptually similar colors in the display's gamut and
- vice versa, but the mapping is typically not 1:1 or reversible, nor can it
- be defined with a simple formula.  Thus, such a conversion is out of scope
- for a codec library.  However, the TurboJPEG API allows for compressing
- CMYK pixels into a YCCK JPEG image (see <a href="../../../org/libjpegturbo/turbojpeg/TJ.html#CS_YCCK"><code>CS_YCCK</code></a>) and

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

-   *

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

-%description
-libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2,
-AVX2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression
-on x86, x86-64, ARM, and PowerPC systems, as well as progressive JPEG
-compression on x86 and x86-64 systems.  On such systems, libjpeg-turbo is
-generally 2-6x as fast as libjpeg, all else being equal.  On other types of
-systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by
-virtue of its highly-optimized Huffman coding routines.  In many cases, the
-performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
-
-libjpeg-turbo implements both the traditional libjpeg API as well as the less
-powerful but more straightforward TurboJPEG API.  libjpeg-turbo also features
-colorspace extensions that allow it to compress from/decompress to 32-bit and
-big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java

-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.

+/* These routines combine simple (non-fancy, i.e. non-smooth) h2v1 or h2v2
+ * chroma upsampling and YCbCr -> RGB color conversion into a single function.
+ *
+ * As with the standalone functions, YCbCr -> RGB conversion is defined by the
+ * following equations:
+ *    R = Y                        + 1.40200 * (Cr - 128)
+ *    G = Y - 0.34414 * (Cb - 128) - 0.71414 * (Cr - 128)
+ *    B = Y + 1.77200 * (Cb - 128)
+ *
+ * Scaled integer constants are used to avoid floating-point arithmetic:
+ *    0.3441467 = 11277 * 2^-15
+ *    0.7141418 = 23401 * 2^-15
+ *    1.4020386 = 22971 * 2^-14
+ *    1.7720337 = 29033 * 2^-14
+ * These constants are defined in jdmerge-neon.c.
+ *
+ * To ensure correct results, rounding is used when descaling.
+ */
+
+/* Notes on safe memory access for merged upsampling/YCbCr -> RGB conversion
+ * routines:
+ *
+ * Input memory buffers can be safely overread up to the next multiple of
+ * ALIGN_SIZE bytes, since they are always allocated by alloc_sarray() in
+ * jmemmgr.c.
+ *
+ * The output buffer cannot safely be written beyond output_width, since
+ * output_buf points to a possibly unpadded row in the decompressed image
+ * buffer allocated by the calling program.

+ *

+ * Optimization techniques used to accelerate the inverse DCT calculation:
+ *
+ * In a DCT coefficient block, the coefficients are increasingly likely to be 0
+ * as you move diagonally from top left to bottom right.  If whole rows of
+ * coefficients are 0, then the inverse DCT calculation can be simplified.  On
+ * the first pass of the inverse DCT, we test for three special cases before
+ * defaulting to a full "regular" inverse DCT:
+ *
+ * 1) Coefficients in rows 4-7 are all zero.  In this case, we perform a
+ *    "sparse" simplified inverse DCT on rows 0-3.
+ * 2) AC coefficients (rows 1-7) are all zero.  In this case, the inverse DCT
+ *    result is equal to the dequantized DC coefficients.
+ * 3) AC and DC coefficients are all zero.  In this case, the inverse DCT
+ *    result is all zero.  For the left 4x8 half, this is handled identically
+ *    to Case 2 above.  For the right 4x8 half, we do no work and signal that
+ *    the "sparse" algorithm is required for the second pass.
+ *
+ * In the second pass, only a single special case is tested: whether the AC and
+ * DC coefficients were all zero in the right 4x8 block during the first pass
+ * (refer to Case 3 above.)  If this is the case, then a "sparse" variant of
+ * the second pass is performed for both the left and right halves of the DCT
+ * block.  (The transposition after the first pass means that the right 4x8
+ * block during the first pass becomes rows 4-7 during the second pass.)

- * jsimd_idct_ifast_neon
- *
- * This function contains a fast, not so accurate integer implementation of
- * the inverse DCT (Discrete Cosine Transform). It uses the same calculations
- * and produces exactly the same output as IJG's original 'jpeg_idct_ifast'
- * function from jidctfst.c
- *
- * Normally 1-D AAN DCT needs 5 multiplications and 29 additions.
- * But in ARM NEON case some extra additions are required because VQDMULH
- * instruction can't handle the constants larger than 1. So the expressions
- * like "x * 1.082392200" have to be converted to "x * 0.082392200 + x",
- * which introduces an extra addition. Overall, there are 6 extra additions
- * per 1-D IDCT pass, totalling to 5 VQDMULH and 35 VADD/VSUB instructions.

- * This function contains inverse-DCT code for getting reduced-size

- * and produces exactly the same output as IJG's original 'jpeg_idct_4x4'
- * function from jpeg-6b (jidctred.c).
- *
- * NOTE: jpeg-8 has an improved implementation of 4x4 inverse-DCT, which
- *       requires much less arithmetic operations and hence should be faster.
- *       The primary purpose of this particular NEON optimized function is
- *       bit exact compatibility with jpeg-6b.
- *
- * TODO: a bit better instructions scheduling can be achieved by expanding
- *       idct_helper/transpose_4x4 macros and reordering instructions,
- *       but readability will suffer somewhat.

- * and produces exactly the same output as IJG's original 'jpeg_idct_2x2'
- * function from jpeg-6b (jidctred.c).
- *
- * NOTE: jpeg-8 has an improved implementation of 2x2 inverse-DCT, which
- *       requires much less arithmetic operations and hence should be faster.
- *       The primary purpose of this particular NEON optimized function is
- *       bit exact compatibility with jpeg-6b.

- * jsimd_idct_ifast_neon
- *
- * This function contains a fast, not so accurate integer implementation of

- * and produces exactly the same output as IJG's original 'jpeg_idct_ifast'
- * function from jidctfst.c
- *
- * Normally 1-D AAN DCT needs 5 multiplications and 29 additions.
- * But in ARM NEON case some extra additions are required because VQDMULH
- * instruction can't handle the constants larger than 1. So the expressions
- * like "x * 1.082392200" have to be converted to "x * 0.082392200 + x",
- * which introduces an extra addition. Overall, there are 6 extra additions
- * per 1-D IDCT pass, totalling to 5 VQDMULH and 35 VADD/VSUB instructions.

- * jsimd_idct_4x4_neon
- *
- * This function contains inverse-DCT code for getting reduced-size
- * 4x4 pixels output from an 8x8 DCT block. It uses the same  calculations
- * and produces exactly the same output as IJG's original 'jpeg_idct_4x4'
- * function from jpeg-6b (jidctred.c).
- *
- * NOTE: jpeg-8 has an improved implementation of 4x4 inverse-DCT, which
- *       requires much less arithmetic operations and hence should be faster.
- *       The primary purpose of this particular NEON optimized function is
- *       bit exact compatibility with jpeg-6b.
- *
- * TODO: a bit better instructions scheduling can be achieved by expanding
- *       idct_helper/transpose_4x4 macros and reordering instructions,
- *       but readability will suffer somewhat.

+;
+; NOTES:
+; When shuffling data, we try to avoid pinsrw as much as possible, since it is
+; slow on many CPUs.  Its reciprocal throughput (issue latency) is 1 even on
+; modern CPUs, so chains of pinsrw instructions (even with different outputs)
+; can limit performance.  pinsrw is a VectorPath instruction on AMD K8 and
+; requires 2 µops (with memory operand) on Intel.  In either case, only one
+; pinsrw instruction can be decoded per cycle (and nothing else if they are
+; back-to-back), so out-of-order execution cannot be used to work around long
+; pinsrw chains (though for Sandy Bridge and later, this may be less of a
+; problem if the code runs from the µop cache.)
+;
+; We use tzcnt instead of bsf without checking for support.  The instruction is
+; executed as bsf on CPUs that don't support tzcnt (encoding is equivalent to
+; rep bsf.)  The destination (first) operand of bsf (and tzcnt on some CPUs) is
+; an input dependency (although the behavior is not formally defined, Intel
+; CPUs usually leave the destination unmodified if the source is zero.)  This
+; can prevent out-of-order execution, so we clear the destination before
+; invoking tzcnt.

-; These macros perform the same task as the emit_bits() function in the
-; original libjpeg code.  In addition to reducing overhead by explicitly
-; inlining the code, additional performance is achieved by taking into
-; account the size of the bit buffer and waiting until it is almost full
-; before emptying it.  This mostly benefits 64-bit platforms, since 6
-; bytes can be stored in a 64-bit bit buffer before it has to be emptied.
+; Shorthand used to describe SIMD operations:
+; wN:  xmmN treated as eight signed 16-bit values
+; wN[i]:  perform the same operation on all eight signed 16-bit values, i=0..7
+; bN:  xmmN treated as 16 unsigned 8-bit values
+; bN[i]:  perform the same operation on all 16 unsigned 8-bit values, i=0..15
+; Contents of SIMD registers are shown in memory order.

+; NOTES:
+; When shuffling data, we try to avoid pinsrw as much as possible, since it is
+; slow on many CPUs.  Its reciprocal throughput (issue latency) is 1 even on
+; modern CPUs, so chains of pinsrw instructions (even with different outputs)
+; can limit performance.  pinsrw is a VectorPath instruction on AMD K8 and
+; requires 2 µops (with memory operand) on Intel.  In either case, only one
+; pinsrw instruction can be decoded per cycle (and nothing else if they are
+; back-to-back), so out-of-order execution cannot be used to work around long
+; pinsrw chains (though for Sandy Bridge and later, this may be less of a
+; problem if the code runs from the µop cache.)
+;
+; We use tzcnt instead of bsf without checking for support.  The instruction is
+; executed as bsf on CPUs that don't support tzcnt (encoding is equivalent to
+; rep bsf.)  The destination (first) operand of bsf (and tzcnt on some CPUs) is
+; an input dependency (although the behavior is not formally defined, Intel
+; CPUs usually leave the destination unmodified if the source is zero.)  This
+; can prevent out-of-order execution, so we clear the destination before
+; invoking tzcnt.

 In general, a specific sample value is accessed by code such as
-        GETJSAMPLE(image[colorcomponent][row][col])
+        image[colorcomponent][row][col]
 where col is measured from the image left edge, but row is measured from the
 first sample row currently in memory.  Either of the first two indexings can
 be precomputed by copying the relevant pointer.

-                        machines due to varying roundoff behavior, whereas the

+                        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 fast 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
+                        fast algorithm are much less noticeable.  On modern
+                        x86/x86-64 CPUs that support AVX2 instructions, the
+                        fast and int methods have similar performance.  On
+                        other types of CPUs, the fast method is generally about
+                        5-15% faster than the int 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 fast and int methods becomes
+                        more pronounced.  With images compressed using
+                        quality=97, for instance, the fast method incurs
+                        generally about a 4-6 dB loss in PSNR relative to the
+                        int method, but this can be larger for some images.  If
+                        you can avoid it, do not use the fast method when
+                        decompressing images that were compressed using quality
+                        levels above 97.  The algorithm often degenerates for
+                        such images and can actually produce a more lossy
+                        output image than if the JPEG image had been compressed
+                        using lower quality levels.
+        -dct float      Use floating-point DCT method [legacy feature].
+                        The float method does not produce significantly more
+                        accurate results than the int method, and it is much
+                        slower.  The float method may also give different
+                        results on different machines due to varying roundoff
+                        behavior, whereas the integer methods should give the
+                        same results on all machines.

         -crop WxH+X+Y   Crop to a rectangular region of width W and height H,
                         starting at point X,Y.
 
+If W or H is larger than the width/height of the input image, then the output
+image is expanded in size, and the expanded region is filled in with zeros
+(neutral gray).  Attaching an 'f' character ("flatten") to the width number
+will cause each block in the expanded region to be filled in with the DC
+coefficient of the nearest block in the input image rather than grayed out.
+Attaching an 'r' character ("reflect") to the width number will cause the
+expanded region to be filled in with repeated reflections of the input image
+rather than grayed out.
+
+A complementary lossless wipe option is provided to discard (gray out) data
+inside a given image region while losslessly preserving what is outside:
+        -wipe WxH+X+Y   Wipe (gray out) a rectangular region of width W and
+                        height H from the input image, starting at point X,Y.
+
+Attaching an 'f' character ("flatten") to the width number will cause the
+region to be filled with the average of adjacent blocks rather than grayed out.
+If the wipe region and the region outside the wipe region, when adjusted to the
+nearest iMCU boundary, form two horizontally adjacent rectangles, then
+attaching an 'r' character ("reflect") to the width number will cause the wipe
+region to be filled with repeated reflections of the outside region rather than
+grayed out.
+
+A lossless drop option is also provided, which allows another JPEG image to be
+inserted ("dropped") into the input image data at a given position, replacing
+the existing image data at that position:
+        -drop +X+Y filename     Drop (insert) another image at point X,Y
+
+Both the input image and the drop image must have the same subsampling level.
+It is best if they also have the same quantization (quality.)  Otherwise, the
+quantization of the output image will be adapted to accommodate the higher of
+the input image quality and the drop image quality.  The trim option can be
+used with the drop option to requantize the drop image to match the input
+image.  Note that a grayscale image can be dropped into a full-color image or
+vice versa, as long as the full-color image has no vertical subsampling.  If
+the input image is grayscale and the drop image is full-color, then the
+chrominance channels from the drop image will be discarded.
+
 Other not-strictly-lossless transformation switches are:
 
         -grayscale      Force grayscale output.

-/* The pseudo-compression algorithm.
- *
- * In this module we simply output each pixel value as a separate symbol;
- * thus, no compression occurs.  In fact, there is expansion of one bit per
- * pixel, because we use a symbol width one bit wider than the pixel width.
- *
- * GIF ordinarily uses variable-width symbols, and the decoder will expect
- * to ratchet up the symbol width after a fixed number of symbols.
- * To simplify the logic and keep the expansion penalty down, we emit a
- * GIF Clear code to reset the decoder just before the width would ratchet up.
- * Thus, all the symbols in the output file will have the same bit width.
- * Note that emitting the Clear codes at the right times is a mere matter of
- * counting output symbols and is in no way dependent on the LZW patent.
- *
- * With a small basic pixel width (low color count), Clear codes will be
- * needed very frequently, causing the file to expand even more.  So this
- * simplistic approach wouldn't work too well on bilevel images, for example.
- * But for output of JPEG conversions the pixel width will usually be 8 bits
- * (129 to 256 colors), so the overhead added by Clear symbols is only about
- * one symbol in every 256.

+ * pixel, because we use a symbol width one bit wider than the pixel width.
+ *
+ * GIF ordinarily uses variable-width symbols, and the decoder will expect

+ * To simplify the logic and keep the expansion penalty down, we emit a
+ * GIF Clear code to reset the decoder just before the width would ratchet up.
+ * Thus, all the symbols in the output file will have the same bit width.
+ * Note that emitting the Clear codes at the right times is a mere matter of
+ * counting output symbols and is in no way dependent on the LZW algorithm.
+ *
+ * With a small basic pixel width (low color count), Clear codes will be
+ * needed very frequently, causing the file to expand even more.  So this
+ * simplistic approach wouldn't work too well on bilevel images, for example.
+ * But for output of JPEG conversions the pixel width will usually be 8 bits
