I'v done the 8-bit indexed color encoder, include uniform and median cut way, the median cut arithmetic speed is optimized from first implementation 16s to now about 1s for a 800*600 image. (And the opaque true color encoding is really opaque 24-bit true color, different from adobe implementation of a 32-bit simulated opaque get a little big file size) Later i'll try to open source it if there's some one think it is useful. :) -- iiley AsWing http://www.aswing.org Personal http://www.iiley.com
