At least one difference the "save the background color" toggle does, is, when you uncheck "save colors from transparent pixels", all transparent pixels are reset to the background color if it is ON or to Black, if it is off. I am posting it on this thread because it is an information that would be hard to find out by trial and error, and it is part of one of my few (rather few) code contribs. to the GIMP. ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Either way, IE will show as background what your background color (in the color chooser) was when you saved your image. ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

(I am using GIMP pre-2.0) Erm, last I checked, you have your background color (in the color chooser) be what you want the PNGs background color to be, then when you save the PNG, you make sure "Save Background Color" is turned on.

I wish to set the optional png background color to be #222, the background color of the webpage where the logo is. In this case even IE failed to rander alpha channel the picture is still displayed with a not-very-ugly background. But how? Is it possible? (I am using GIMP pre-2.0) If this can't be done with Gimp, you can use TweakPNG: http://entropymine.com/jason/tweakpng/ This is a Windows app that can be used to set PNG attributes, like the background color. This also runs under "wine" on Linux. :) Peace... Tom ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
