1.1、libjpeg-turbo简介

是什么 ?	`:`	`a JPEG image codec that uses SIMD instructions (MMX, SSE2, AVX2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems`
开发语言	`:`	C++
官方主页	`:`	https://www.libjpeg-turbo.org
源码仓库	`:`	https://github.com/libjpeg-turbo/libjpeg-turbo

libjpeg-turbo是对libjpeg的fork。然后在此基础上进行了优化，使得运行效率大幅提升。所以，现在大多数使用者倾向于使用libjpeg-turbo而不是libjpeg，很多的包管理器中也只有libjpeg-turbo，而没有提供libjpeg。
