Independent JPEG Group's JPEG Software
Software to implement JPEG image compression and decompression. JPEG
(pronounced "jay-peg") is a standardized compression method for
full-color and grayscale images. JPEG is intended for compressing
"real-world" scenes (most of the time these are pictures that have been
scanned-in with a scanner or taken with a digital camera). Cartoons and
other nonrealistic images are not its strong suit. It should be noted
that JPEG output is not necessarily the same as its input. If this is a
factor for you, do not use it. With typical real-world scenes, JPEG can
achieve high compression rates without noticeable differences. If you
can accept pictures of lower quality, JPEG can achieve amazingly high
compression rates.
There are some library functions available for reading and writing JPEG
files. The 'cjpeg' and 'djpeg' applications use the library to make
conversions between JPEG and other popular graphic file formats
possible. The JPEG library is meant to be used within other
applications.
Cjpeg compresses the input file, or standard input if no filename is
given, and produces a JPEG/JFIF file as standard output. Currently
supported input file formats include: PPM (PBMPLUS color format), PGM
(PBMPLUS Grayscale format), BMP, GIF, Targa, and RLE (Utah Raster
Toolkit Format) (RLE is only supported if the RLE library is
available). Djpeg decompresses a JPEG file into one of the above
mentioned formats.

- version update to 2.1.1
1. Fixed a regression introduced in 2.1.0 that caused build failures
with non-GCC-compatible compilers for Un*x/Arm platforms.
2. Fixed a regression introduced by 2.1 beta1[13] that prevented the
Arm 32-bit (AArch32) Neon SIMD extensions from building unless
the C compiler flags included -mfloat-abi=softfp or -mfloat-abi=hard.
3. Fixed an issue in the AArch32 Neon SIMD Huffman encoder whereby
reliance on undefined C compiler behavior led to crashes
("SIGBUS: illegal alignment") on Android systems when running
AArch32/Thumb builds of libjpeg-turbo built with recent versions
of Clang.
4. Added a command-line argument (-copy icc) to jpegtran that causes
it to copy only the ICC profile markers from the source file and
discard any other metadata.
5. libjpeg-turbo should now build and run on CHERI-enabled
architectures, which use capability pointers that are larger than
the size of size_t.
6. Fixed a regression introduced by 2.1 beta1[5] that caused a segfault
in the 64-bit SSE2 Huffman encoder when attempting to losslessly
transform a specially-crafted malformed JPEG image.
