Hi, I already sent this in mid-July, but it seems to have gotten lost, and I forgot about it too. So here goes again:
I wrote the attached script to auto-generate menubar entries in Makefiles using the Gimp. It needs Gimp 1.2 and the xfonts-scalable-nonfree package for the luximono font. See the top of the script for usage instructions. The PNGs output by this script display OK on Netscape 4.7; if the /CD/ table background colour is set to 0xdd9988, there is no colour difference for me on a 24bpp display. Still, I wouldn't be surprised if NS 4 still displayed things incorrectly for lower colour depths. For other browsers (which support PNG transparency), even a slightly incorrect display shouldn't be noticeable. For me, it always leaves a transparent 8 pixel wide area at the right edge of the generated image. This isn't too much of a problem IMHO, so I'm not trying to work around what I believe is a bug in Gimp's string-extent measuring command. Josip, maybe you could take care of integrating this into the Makefiles and translation system? :-) Cheers, Richard -- __ _ |_) /| Richard Atterer | CS student at the Technische | GnuPG key: | \/¯| http://atterer.net | Universität München, Germany | 0x888354F7 ¯ '` ¯
