rdopng looks pretty cool, TILI wonder how much further compression ratio could be improved with a lossy filter like rdopng.
I think you would get the best results with the rdopng PNG encoder, but using zstd (or brotli) to encode the differential vs miniz. With zstd that is the "ZPNG" codec in the above-posted graph. (but then, JPEG decodes faster than PNG anyway if you can go lossy, so it would be for transparent things).
