AMGIF doesn't handle the overscan? I've done several overscan images to GIF with no trouble whatsoever. Now, HAMGIF, the *display* program, doesn't know about overscan resolutions and messes up the aspect ratio quite badly when displaying a GIF encoded overscan image, but the image has always encoded correctly to my knowledge… –>Steve Bennett

The overscan images I have converted to GIF have always come out horizontally 'squeezed: on the IBM side. Hmm…… I'll do some more today and re-check.

That's probably for the same reason they look that way under HAMGIF. The display program looks at the file, says "Hey! The horizontal resolution is more than 320… Obviously it needs to be displayed in a 640 horizontal mode", and *poof*, it comes out horizontally squeezed… <grin> A number of IBM GIF display programs do the same thing with non-overscan 320 x 400 images, because the height is more than 200. –>Steve Bennett
