Hi, shouldn't you use RAW format images for input instead of JPEG compressed files?

Ah, I'm sorry. I meant to ask if it is intentional that the README shows test results for compressing JPEGs, rather than raw files. My understanding is that the raster of pixels you get out of a JPEG decoder will always have some certain characteristics which will make it inherently compressible--you know, those blocks of pixels that are smooth gradients rather than the "random" bag of values you'd observe in a RAW file. I think compression performance statistics on RAW files would tell us more.
