description = """
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2,
NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86,
x86-64, ARM, and PowerPC 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.).
"""
usage = """
The libjpeg-turbo package contains a number of command line utilities:
+ cjpeg: compress an image file to a JPEG file
+ djpeg: Decompress a JPEG file to an image file
+ jpegtran: Lossless transformation of JPEG files
+ rdjpgcom: Display text comments from a JPEG file
+ wrjpgcom: Insert text comments into a JPEG file
Extensive help is available for these commands as Linux man pages. All
commands also support the --help command line option.

The module also provides the benchmarking tool tjbench.

The API-documentation is web-based.
