I've modified the bitmap editor (the one that comes with X 10.4) so that it has two extra commands, Flip Horizontal and Flip Vertical. Useful for quickly converting a bitmap of a left-facing Blue Space Lemur into a right-facing Blue Space Lemur. Or something like that. Anyhow, here's the diffs to apply to bitmap.c, via the command: ( cat diffs ; echo '1,$p' ) | ed - bitmap.c > bitmap.c.new John Bradley (bradley@cis.upenn.edu) "Patch program?!?
