JPEG has quite a few nice things going for it and I use it all the time with ImageFX. For one thing, JPEG is a 24-bit (16 million color) compressed image format while GIF is only 8-bit (256 colors), so you have a much larger palette to work with in the color map conversions. As far as the JFIF datatype, it might do a much better job of dithering than ZGIF. So as far as I'm concerned, it wouldn't bother me a bit if GIF dies because of the Unisys/CompuServe royalty fiasco. JPEG might not be the best if you need 24-bit true color accuracy because of it's degrading of the image depending on compression, but for most purposes, it does a good job. // John (Warp 4040 & Emplant Quadra 840) \X/ Mercury@ins.infonet.net
