libjpeg-turbo 介绍
libjpeg-turbo 是一个专门为 x86 和 x86-64 处理器优化的高速
libjpeg 的改进版本。
It uses SIMD instructions (MMX, SSE, SSE2) to accelerate baseline JPEG
compression and decompression. libjpeg-turbo is generally 2-4 times as fast as
the unmodified version of libjpeg. It also includes a wrapper library for the
TurboJPEG API used by VirtualGL and TurboVNC. It was originally based on
libjpeg/SIMD but has improved support for Mac OS X, 64-bit platforms, 32-bit
and big endian pixel formats (RGBA/BGRA/ABGR/ARGB), accelerated Huffman
encoding/decoding, and varIoUs other fixes
