Yeah, I'm not sure about the speed, but I'm sure that for the same results, libraries like nvidia's that use a pseudo-brute force approach are much slower. squish also contains a fast range compressor, but it's results are usually easy to beat testing all the pairs, or using a greedy heuristic optimization method and those are not much slower. However, I think it makes more sense to use squish in tools like the gimp plugin and stop abusing of the opengl driver. > It should be pretty easy to convert this library to be suitable for the > existing API, there's really not that much interface involved (it needs > to be able to handle images smaller than 4x4 however, haven't checked). > If it turns out to be better I guess I'd just drop development of my own > library (not that I'd have really done much since the first version...). Handling small images should be easy, I usually replicate the image over the block, so that the compression code doesn't have to handle any special cases. -- Ignacio Castaño [EMAIL PROTECTED] ------------------------------------------------------- Using Tomcat but need to do more?
