Well, that's what GIMP does. I guess it's a workaround and it'll be 99.99% accurate since 100% transparent BMPs aren't exactly popular. 32-bit BMPs aren't popular either. If my patch is not ok for the upstream, I'll just keep it private.

I haven't benchmarked BMP vs PNG loading speed with Evas. The 'BMP is faster to load' argument is based on various icon-loading (small 32x32 icons) tests I performed on my prior project (ARM920T device @400MHz), which uses SDL/SDL_Image. I think Evas is smarter with images but I just assume loading/render of raw data (BMP) would be faster than with compressed PNG files. > > -- > ------------- Codito, ergo sum - "I code, therefore I am" -------------- > The Rasterman (Carsten Haitzler) ras...@rasterman.com > > -- brian ------------------ Cool-Karaoke - The smallest recording studio, in your palm, open-sourced http://cool-idea.com.tw/ iMaGiNaTiOn iS mOrE iMpOrTaNt tHaN kNoWlEdGe ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ enlightenment-devel mailing list enlightenment-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-devel
