Also I could see it with zstd (which is a lot more than 100k, though very fast indeed) but I’m a bit doubtful about lz4, it’s generally worse than deflate (which png uses) at compression and qoi lacks filtering.
- duskwuff 4y agoQOI's QOI_OP_DIFF and QOI_OP_LUMA opcodes can act like horizontal filtering once the results are fed into a stream compressor. There's nothing to provide vertical filtering, though, which is a pretty huge limitation. I wonder if you'd get better compression using a zigzag scan?
- adgjlsfhk1 4y agothere was some work done to find better scan arrangements. unfortunately, is pretty hard to do so without storing the previous row in memory which has a pretty large effect on speed
