The unfortunate answer is that it cannot be done; there is, technically, a problem with anti-aliasing text over a transparent background. GIF implements transparency by specifying a single color in the colormap to be transparent. They (CompuServe?) could have defined the GIF file format to treat a range of indexes in the palette to represent varying levels of transparency, but they did not. There is nothing the GIMP can do to overcome this limitation of the GIF format. The PNG format DOES support an alpha channel, even in Index Mode; so you might see if that meets your needs. One thing to note is that converting to Indexed Mode in the GIMP will alias your layers even if the background of the image is not transparent. However, if you remain in RGB Mode and let the GIF save plug-in perform the Indexed conversion, the fonts will be anti-aliased properly (alternately, you could Merge the layers or flatten the image in RGB Mode and then convert the result to Indexed Mode). It is not ideal that the GIMP assumes the transparency limitation of the GIF format in its Indexed Mode editing but it is an understandably low priority problem. Discussions continue on how best (or even whether) to handle indexed images but it is unlikely that any changes will occur in the near future. _______________________________________________ Gimp-user mailing list [email protected] https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
