Format-specific file optimization #82

Open eevee opened 11 years ago

eevee commented 11 years ago

optipng for PNG
gifsicle for GIF
Lossless EXIF rotation for JPEG
I believe there are JPEG optimizers, somewhere

These add a good bit of server-side time, though. Staging area (#13) may help. We could do this async in the background, but because we key by file hash, the art wouldn't be available until we were done. Ugh.

I just did JPEG rotation and optimization for shurtapp recently; see https://github.com/habnabit/shurtapp/blob/master/photo-pipeline/process-image.sh

This seems like exactly what you want, modulo the -resize option to imagemagick. I found some random dude's jpeg compression parameters which, on average, compress jpegs smaller than any other encoder I've seen.
