2.0.3
=====
### Significant changes relative to 2.0.2:
1. Fixed "using JNI after critical get" errors that occurred on Android
platforms when passing invalid arguments to certain methods in the TurboJPEG
Java API.
2. Fixed a regression in the SIMD feature detection code, introduced by
the AVX2 SIMD extensions (2.0 beta1[1]), that was known to cause an illegal
instruction exception, in rare cases, on CPUs that lack support for CPUID leaf
07H (or on which the maximum CPUID leaf has been limited by way of a BIOS
setting.)
3. The 4:4:0 (h1v2) fancy (smooth) chroma upsampling algorithm in the
decompressor now uses a similar bias pattern to that of the 4:2:2 (h2v1) fancy
chroma upsampling algorithm, rounding up or down the upsampled result for
alternate pixels rather than always rounding down. This ensures that,
regardless of whether a 4:2:2 JPEG image is rotated or transposed prior to
decompression (in the frequency domain) or after decompression (in the spatial
domain), the final image will be similar.
4. Fixed an integer overflow and subsequent segfault that occurred when
attempting to compress or decompress images with more than 1 billion pixels
using the TurboJPEG API.
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 16 would result in an
error ("Missing Huffman code table entry") and an invalid JPEG image.
6. Fixed an issue whereby `tjDecodeYUV()` and `tjDecodeYUVPlanes()` would throw
an error ("Invalid progressive parameters") or a warning ("Inconsistent
progression sequence") if passed a TurboJPEG instance that was previously used
to decompress a progressive JPEG image.
2.0.2
=====
### Significant changes relative to 2.0.1:
1. Fixed a regression introduced by 2.0.1[5] that prevented a runtime search
path (rpath) from being embedded in the libjpeg-turbo shared libraries and
executables for macOS and iOS. This caused a fatal error of the form
"dyld: Library not loaded" when attempting to use one of the executables,
unless `DYLD_LIBRARY_PATH` was explicitly set to the location of the
libjpeg-turbo shared libraries.
2. Fixed an integer overflow and subsequent segfault (CVE-2018-20330) that
occurred when attempting to load a BMP file with more than 1 billion pixels
using the `tjLoadImage()` function.
3. Fixed a buffer overrun (CVE-2018-19664) that occurred when attempting to
decompress a specially-crafted malformed JPEG image to a 256-color BMP using
djpeg.
4. Fixed a floating point exception that occurred when attempting to
decompress a specially-crafted malformed JPEG image with a specified image
width or height of 0 using the C version of TJBench.
5. The TurboJPEG API will now decompress 4:4:4 JPEG images with 2x1, 1x2, 3x1,
or 1x3 luminance and chrominance sampling factors. This is a non-standard way
of specifying 1x subsampling (normally 4:4:4 JPEGs have 1x1 luminance and
chrominance sampling factors), but the JPEG format and the libjpeg API both
allow it.
6. Fixed a regression introduced by 2.0 beta1[7] that caused djpeg to generate
incorrect PPM images when used with the `-colors` option.
7. Fixed an issue whereby a static build of libjpeg-turbo (a build in which
`ENABLE_SHARED` is `0`) could not be installed using the Visual Studio IDE.
8. Fixed a severe performance issue in the Loongson MMI SIMD extensions that
occurred when compressing RGB images whose image rows were not 64-bit-aligned.
2.0.1
=====
### Significant changes relative to 2.0.0:
1. Fixed a regression introduced with the new CMake-based Un*x build system,
whereby jconfig.h could cause compiler warnings of the form
`"HAVE_*_H" redefined` if it was included by downstream Autotools-based
projects that used `AC_CHECK_HEADERS()` to check for the existence of locale.h,
stddef.h, or stdlib.h.
2. The `jsimd_quantize_float_dspr2()` and `jsimd_convsamp_float_dspr2()`
functions in the MIPS DSPr2 SIMD extensions are now disabled at compile time
if the soft float ABI is enabled. Those functions use instructions that are
incompatible with the soft float ABI.
3. Fixed a regression in the SIMD feature detection code, introduced by
the AVX2 SIMD extensions (2.0 beta1[1]), that caused libjpeg-turbo to crash on
Windows 7 if Service Pack 1 was not installed.
4. Fixed out-of-bounds read in cjpeg that occurred when attempting to compress
a specially-crafted malformed color-index (8-bit-per-sample) Targa file in
which some of the samples (color indices) exceeded the bounds of the Targa
file's color table.
5. Fixed an issue whereby installing a fully static build of libjpeg-turbo
(a build in which `CFLAGS` contains `-static` and `ENABLE_SHARED` is `0`) would
fail with "No valid ELF RPATH or RUNPATH entry exists in the file."
2.0.0
=====
### Significant changes relative to 2.0 beta1:
1. The TurboJPEG API can now decompress CMYK JPEG images that have subsampled M
and Y components (not to be confused with YCCK JPEG images, in which the C/M/Y
components have been transformed into luma and chroma.) Previously, an error
was generated ("Could not determine subsampling type for JPEG image") when such
an image was passed to `tjDecompressHeader3()`, `tjTransform()`,
`tjDecompressToYUVPlanes()`, `tjDecompressToYUV2()`, or the equivalent Java
methods.
2. Fixed an issue (CVE-2018-11813) whereby a specially-crafted malformed input
file (specifically, a file with a valid Targa header but incomplete pixel data)
would cause cjpeg to generate a JPEG file that was potentially thousands of
times larger than the input file. The Targa reader in cjpeg was not properly
detecting that the end of the input file had been reached prematurely, so after
all valid pixels had been read from the input, the reader injected dummy pixels
with values of 255 into the JPEG compressor until the number of pixels
specified in the Targa header had been compressed. The Targa reader in cjpeg
now behaves like the PPM reader and aborts compression if the end of the input
file is reached prematurely. Because this issue only affected cjpeg and not
the underlying library, and because it did not involve any out-of-bounds reads
or other exploitable behaviors, it was not believed to represent a security
threat.
3. Fixed an issue whereby the `tjLoadImage()` and `tjSaveImage()` functions
would produce a "Bogus message code" error message if the underlying bitmap and
PPM readers/writers threw an error that was specific to the readers/writers
(as opposed to a general libjpeg API error.)
4. Fixed an issue whereby a specially-crafted malformed BMP file, one in which
the header specified an image width of 1073741824 pixels, would trigger a
floating point exception (division by zero) in the `tjLoadImage()` function
when attempting to load the BMP file into a 4-component image buffer.
5. Fixed an issue whereby certain combinations of calls to
`jpeg_skip_scanlines()` and `jpeg_read_scanlines()` could trigger an infinite
loop when decompressing progressive JPEG images that use vertical chroma
subsampling (for instance, 4:2:0 or 4:4:0.)
6. Fixed a segfault in `jpeg_skip_scanlines()` that occurred when decompressing
a 4:2:2 or 4:2:0 JPEG image using the merged (non-fancy) upsampling algorithms
(that is, when setting `cinfo.do_fancy_upsampling` to `FALSE`.)
7. The new CMake-based build system will now disable the MIPS DSPr2 SIMD
extensions if it detects that the compiler does not support DSPr2 instructions.
8. Fixed out-of-bounds read in cjpeg that occurred when attempting to compress
a specially-crafted malformed color-index (8-bit-per-sample) BMP file in which
some of the samples (color indices) exceeded the bounds of the BMP file's color
table.
9. Fixed a signed integer overflow in the progressive Huffman decoder, detected
by the Clang and GCC undefined behavior sanitizers, that could be triggered by
attempting to decompress a specially-crafted malformed JPEG image. This issue
did not pose a security threat, but removing the warning made it easier to
detect actual security issues, should they arise in the future.
1.5.90 (2.0 beta1)
==================
### Significant changes relative to 1.5.3:
1. Added AVX2 SIMD implementations of the colorspace conversion, chroma
downsampling and upsampling, integer quantization and sample conversion, and
slow integer DCT/IDCT algorithms. When using the slow integer DCT/IDCT
algorithms on AVX2-equipped CPUs, the compression of RGB images is
approximately 13-36% (avg. 22%) faster (relative to libjpeg-turbo 1.5.x) with
64-bit code and 11-21% (avg. 17%) faster with 32-bit code, and the
decompression of RGB images is approximately 9-35% (avg. 17%) faster with
64-bit code and 7-17% (avg. 12%) faster with 32-bit code. (As tested on a
3 GHz Intel Core i7. Actual mileage may vary.)
2. Overhauled the build system to use CMake on all platforms, and removed the
autotools-based build system. This decision resulted from extensive
discussions within the libjpeg-turbo community. libjpeg-turbo traditionally
used CMake only for Windows builds, but there was an increasing amount of
demand to extend CMake support to other platforms. However, because of the
unique nature of our code base (the need to support different assemblers on
each platform, the need for Java support, etc.), providing dual build systems
as other OSS imaging libraries do (including libpng and libtiff) would have
created a maintenance burden. The use of CMake greatly simplifies some aspects
of our build system, owing to CMake's built-in support for various assemblers,
Java, and unit testing, as well as generally fewer quirks that have to be
worked around in order to implement our packaging system. Eliminating
autotools puts our project slightly at odds with the traditional practices of
the OSS community, since most "system libraries" tend to be built with
autotools, but it is believed that the benefits of this move outweigh the
risks. In addition to providing a unified build environment, switching to
CMake allows for the use of various build tools and IDEs that aren't supported
under autotools, including XCode, Ninja, and Eclipse. It also eliminates the
need to install autotools via MacPorts/Homebrew on OS X and allows
libjpeg-turbo to be configured without the use of a terminal/command prompt.
Extensive testing was conducted to ensure that all features provided by the
autotools-based build system are provided by the new build system.
3. The libjpeg API in this version of libjpeg-turbo now includes two additional
functions, `jpeg_read_icc_profile()` and `jpeg_write_icc_profile()`, that can
be used to extract ICC profile data from a JPEG file while decompressing or to
embed ICC profile data in a JPEG file while compressing or transforming. This
eliminates the need for downstream projects, such as color management libraries
and browsers, to include their own glueware for accomplishing this.
4. Improved error handling in the TurboJPEG API library:
- Introduced a new function (`tjGetErrorStr2()`) in the TurboJPEG C API
that allows compression/decompression/transform error messages to be retrieved
in a thread-safe manner. Retrieving error messages from global functions, such
as `tjInitCompress()` or `tjBufSize()`, is still thread-unsafe, but since those
functions will only throw errors if passed an invalid argument or if a memory
allocation failure occurs, thread safety is not as much of a concern.
- Introduced a new function (`tjGetErrorCode()`) in the TurboJPEG C API
and a new method (`TJException.getErrorCode()`) in the TurboJPEG Java API that
can be used to determine the severity of the last
compression/decompression/transform error. This allows applications to
choose whether to ignore warnings (non-fatal errors) from the underlying
libjpeg API or to treat them as fatal.
- Introduced a new flag (`TJFLAG_STOPONWARNING` in the TurboJPEG C API and
`TJ.FLAG_STOPONWARNING` in the TurboJPEG Java API) that causes the library to
immediately halt a compression/decompression/transform operation if it
encounters a warning from the underlying libjpeg API (the default behavior is
to allow the operation to complete unless a fatal error is encountered.)
5. Introduced a new flag in the TurboJPEG C and Java APIs (`TJFLAG_PROGRESSIVE`
and `TJ.FLAG_PROGRESSIVE`, respectively) that causes the library to use
progressive entropy coding in JPEG images generated by compression and
transform operations. Additionally, a new transform option
(`TJXOPT_PROGRESSIVE` in the C API and `TJTransform.OPT_PROGRESSIVE` in the
Java API) has been introduced, allowing progressive entropy coding to be
enabled for selected transforms in a multi-transform operation.
6. Introduced a new transform option in the TurboJPEG API (`TJXOPT_COPYNONE` in
the C API and `TJTransform.OPT_COPYNONE` in the Java API) that allows the
copying of markers (including EXIF and ICC profile data) to be disabled for a
particular transform.
7. Added two functions to the TurboJPEG C API (`tjLoadImage()` and
`tjSaveImage()`) that can be used to load/save a BMP or PPM/PGM image to/from a
memory buffer with a specified pixel format and layout. These functions
replace the project-private (and slow) bmp API, which was previously used by
TJBench, and they also provide a convenient way for first-time users of
libjpeg-turbo to quickly develop a complete JPEG compression/decompression
program.
8. The TurboJPEG C API now includes a new convenience array (`tjAlphaOffset[]`)
that contains the alpha component index for each pixel format (or -1 if the
pixel format lacks an alpha component.) The TurboJPEG Java API now includes a
new method (`TJ.getAlphaOffset()`) that returns the same value. In addition,
the `tjRedOffset[]`, `tjGreenOffset[]`, and `tjBlueOffset[]` arrays-- and the
corresponding `TJ.getRedOffset()`, `TJ.getGreenOffset()`, and
`TJ.getBlueOffset()` methods-- now return -1 for `TJPF_GRAY`/`TJ.PF_GRAY`
rather than 0. This allows programs to easily determine whether a pixel format
has red, green, blue, and alpha components.
9. Added a new example (tjexample.c) that demonstrates the basic usage of the
TurboJPEG C API. This example mirrors the functionality of TJExample.java.
Both files are now included in the libjpeg-turbo documentation.
10. Fixed two signed integer overflows in the arithmetic decoder, detected by
the Clang undefined behavior sanitizer, that could be triggered by attempting
to decompress a specially-crafted malformed JPEG image. These issues did not
pose a security threat, but removing the warnings makes it easier to detect
actual security issues, should they arise in the future.
11. Fixed a bug in the merged 4:2:0 upsampling/dithered RGB565 color conversion
algorithm that caused incorrect dithering in the output image. This algorithm
now produces bitwise-identical results to the unmerged algorithms.
12. The SIMD function symbols for x86[-64]/ELF, MIPS/ELF, macOS/x86[-64] (if
libjpeg-turbo is built with YASM), and iOS/ARM[64] builds are now private.
This prevents those symbols from being exposed in applications or shared
libraries that link statically with libjpeg-turbo.
13. Added Loongson MMI SIMD implementations of the RGB-to-YCbCr and
YCbCr-to-RGB colorspace conversion, 4:2:0 chroma downsampling, 4:2:0 fancy
chroma upsampling, integer quantization, and slow integer DCT/IDCT algorithms.
When using the slow integer DCT/IDCT, this speeds up the compression of RGB
images by approximately 70-100% and the decompression of RGB images by
approximately 2-3.5x.
14. Fixed a build error when building with older MinGW releases (regression
caused by 1.5.1[7].)
15. Added SIMD acceleration for progressive Huffman encoding on SSE2-capable
x86 and x86-64 platforms. This speeds up the compression of full-color
progressive JPEGs by about 85-90% on average (relative to libjpeg-turbo 1.5.x)
when using modern Intel and AMD CPUs.

# The output of the floating point tests is not validated by default, because
# the output differs depending on the type of floating point math used, and
# this is only deterministic if the DCT/IDCT are implemented using SIMD
# instructions on a particular platform. Pass one of the following on the make
# command line to validate the floating point tests against one of the expected
# results:
#
# FLOATTEST=sse validate against the expected results from the libjpeg-turbo
# SSE SIMD extensions
# FLOATTEST=32bit validate against the expected results from the C code
# when running on a 32-bit FPU (or when SSE is being used for
# floating point math, which is generally the default with
# x86-64 compilers)
# FLOATTEST=64bit validate against the exepected results from the C code
# when running on a 64-bit FPU
# FLOATTEST=387 validate against the expected results from the C code when
# the 387 FPU is being used for floating point math (which is
# generally the default with x86 compilers)

FILE FORMAT WARS

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 DCT-based 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.
The ISO/IEC JTC1/SC29/WG1 standards committee (also known as JPEG, together
with ITU-T SG16) currently promotes different formats containing the name
"JPEG" which are incompatible with original DCT-based JPEG. IJG therefore does
not support these formats (see REFERENCES). Indeed, one of the original
reasons for developing this free software was to help force convergence on
common, interoperable format standards for JPEG files.
Don't use an incompatible file format!
(In any case, our decoder will remain capable of reading existing JPEG
image files indefinitely.)

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.

#.rst:
# 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.

## dummy dependencies for each header file. Too bad gcc doesn't do

## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as

* Since an ICC profile can be larger than the maximum size of a JPEG marker

* defined by the ICC specifies one or more APP2 markers containing the
* following data:
* Identifying string ASCII "ICC_PROFILE\0" (12 bytes)
* Marker sequence number 1 for first APP2, 2 for next, etc (1 byte)
* Number of markers Total number of APP2's used (1 byte)
* Profile data (remainder of APP2 data)
* Decoders should use the marker sequence numbers to reassemble the profile,
* rather than assuming that the APP2 markers appear in the correct sequence.
