Topic: how to use smusher && paperclip-smusher
I want to use one in two gems to LOSSLESS image size when using paperclip upload image to s3.
With smusher gem : https://github.com/grosser/smusher
I don't know how to do that (run in console ok, but in ruby is error undefine method smusher)
With paperclip-smusher: https://github.com/knightq/paperclip-smusher
