Golang编写的动态JPEG缩略图代理：go-thumber

jopen 9年前

go-thumber是一个Golang编写的动态JPEG缩略图代理，速度快。它只实现了JPEG -> JPEG缩略图。

特性:

  • Input: JPEG (YCbCr 4:4:4, 4:4:0, 4:2:2, 4:2:0, and greyscale modes)
  • Output: JPEG (YCbCr 4:4:4 or greyscale)
  • No color conversion: data is kept in direct planar YCbCr buffers for efficiency and quality
  • Optimized JPEG decoding: decodes only as much data as necessary for a particular resolution
  • Uses libswscale for very fast but high quality scaling (lanczos)
