+JPEG compression and decompression using SIMD instructions: MMX on x86, SSE2 on
+x86-64, NEON on ARM, and AltiVec on PowerPC processors.  Even on other systems,
+its highly-optimized Huffman coding routines allow it to outperform libjpeg by
+a significant amount.
+libjpeg-turbo implements both the traditional libjpeg API and the less powerful
+but more straightforward TurboJPEG API, and provides a full-featured Java
+interface.  It supports color space extensions that allow it to compress from
+and decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.).")
