TinyPNG 官方網(wǎng)址：https://tinypng.com 是一個(gè)非常不錯(cuò)的圖片壓縮工具扎狱，在保持alpha通道的情況下對(duì)PNG的壓縮可以達(dá)到1/3之內(nèi)梧田，而且用肉眼基本上分辨不出壓縮的損失。
=begin
https://tinypng.com/developers/reference/ruby
調(diào)用tinypng的API對(duì)png和jpg格式的圖片進(jìn)行批量壓縮
將TINIFYKEY換成自己申請(qǐng)的key
使用時(shí)需要指定要壓縮的文件夾
ruby tinypng.rb images
壓縮后會(huì)直接覆蓋原有的圖片，壓縮前請(qǐng)自行備份原圖
壓縮失敗的圖片會(huì)保存在ARGV[0]_Failure文件夾下
