Thank Eric and Oleg for help. I'll try to use bmp script. I didn't test the script support compress bmp or not, but I think that will not be too important.
> glbmp=: glpixels_jgl2_@(0 0,$,,)@[EMAIL PROTECTED] I think it should be (0 0,|[EMAIL PROTECTED],,) because glpixels expect x y w h not x y h w It also need to scale bitmap data before feeding to glpixels > Why do you need a delivery format like GIF in memory? Did I mention GIF? AFAIK unisys requires every developer who produce gif paying a LZW license fee so that there is no royalty-free gif encoding library. My knowledge on LZW may be again outdated, but I think png will be a better alternative. Nevertheless I need jpeg. Reading jpeg files, decoding them in memory and pipe to glpixels for display. -- regards, bill ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
