ART100@PSUVM.BITNET (Andy Tefft) (03/07/89)
Thanks to those who sent me the list of FTP sites that was apparently recently posted on here. Now for a new question: what would make a GIF file appear slanted? For example, suppose the picture is supposed to be a box: +---------+ | | | | | | +---------+ but it comes out thus: +----------+ // // // -----++---- Actually the effect is more pronounced than that, but that's the idea. None of the image is lost, but it's wrapped around! Any ideas, or fixes? Andy art100@psuvm.bitnet / a1t@ecl.psu.edu

Assuming it is a problem with the decoding program, somewhere it is eating at least one pixel per line. Hard to say without seeing the source of your program, and without knowing if the image itself is correct. -- Juergen Wagner gandalf@csli.stanford.edu wagner@arisia.xerox.com

Unfortunately I don't remember the format to tell you its position in file, but perhaps some one could tell it. To correct that fault just decrease the image width entry by one or two using a disk editor. -- EARN: teittinen@finuh Internet: teittinen@cc.helsinki.fi Marko Teittinen, student of computer science

Now for a new question: what would make a GIF file appear slanted? For example, suppose the picture is supposed to be a box: +---------+ | | | | | | +---------+ but it comes out thus: +----------+ // // // -----++---- Actually the effect is more pronounced than that, but that's the idea. None of the image is lost, but it's wrapped around! It only happens with a FEW gif's, maybe 3 I've seen so far, and these are all from different sites but the rest from those places came out ok. I'm using gif2ras to convert gif's to sun rasterfiles, then using screenload to view the files. I don't think it's a problem with the raster files since the border is square, just the information in the actual gif file is diagonal! Any ideas, or fixes? Andy art100@psuvm.bitnet / a1t@ecl.psu.edu
