I'd assume that the photo-type image decoder is optimized, right? If so, how does the optimized photo-type decoder compare to the apparently unoptimizable JBIG2 decoder?
- perihelions 3y agoI'm not knowledgeable to speak to that, but just to clarify—the low-hanging fruit in libpng I mentioned is in simple, vectorizable loops—conversions between pixel formats in buffers. Not in its compression algorithm (which isn't part of libpng—it calls out to zlib for that).
