Then all you have to do is to have one layer with foreground (for example an icon or a button) and another layer under it filled with background color. Make sure that your foreground is well adapted to any background color. Then when you want to save your final image you save it in another file and perform the indexing operation and give it a transparent color. -- LEGENY Jozef ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I am used to creating png images with transparent pixels/area that I can safely (safe = even work with the worst browser that people call IE) use on the web, the trick is to convert image with transparency to indexed color with less then 256 colors, save the png image. Now another challenge: I use very bright background color on the web for most png-pixel-transparent images, these images look very bad if they are put on dark background. And for one situation I am in now I have to make these images display fine on viewers that do not support transparency, e.g. xview. If I select the transparent area, clear it to the color I want, then clear it to transparency, and save with 'save background color' ON and 'save color values from transparent pixels' OFF, then xview uses that color correctly. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

You should be able to perform an "Alpha to Selection", "Selection Invert", "Edit-Fill" with the appropriate color, and then "Edit->Clear". You might need to do a colors->threshold on the QuickMask (of the selection) if you only wish to change the color of *fully* transparent pixels.
