Right now the CPU usage of a project I'm working on is dominated by PNG compression. An alternative with significantly faster compression times would be very useful. I'll be watching this closely, and hope that it becomes possible to decode IZ images in the browser (or implement it myself).
PNG compressors generally try a couple different strategies, which can get very expensive. You might be able to ask the compression library to be a little more hands-off, if you don’t need great compression.
Thanks for the suggestion. Unfortunately I'm already specifying the pixel delta strategy that works best with my images, and using the fastest zlib compression setting. Going with no zlib compression would turn my CPU problem into a bandwidth problem :).
