Message-ID: <11597@milton.u.washington.edu> Date: 23 Nov 90 06:28:11 GMT Organization: University of Washington, Seattle Lines: 21 I'll skip the Obsorry-I-don't-read-this-group grovel, and ask a question. I've got about 400 MB of .gif files sitting around and like you probably know, the .gif is a lousy compression format. A couple weeks ago, I read an article on LaPlacian Pyramid compression, and since it looks I'm going to have some time on my hands, decided to write a laplacian compression routine. It seems a good idea that is should be compatible with pre-existing pyrimid files, if the critters exist. So. (1) Has the standard been defined by a responsible group? (2) If not, is there a general format that is being used? (3) If not, is there one you'd like to see? and finally (4) Can I get out of the whole thing? Is there a gif2lap.c floating around? Thanks.
