Wanting to understand issue with transparent GIF export
Hi,
I know there's an entry in the FAQ on the wiki about this, but I was wondering if anyone could shed more light on why this isn't working if you export to GIF rather than PNG.
I know IE doesn't support PNG (which is what the FAQ entry is about), but if I create a transparent GIF with the Gimp, I get a transparent GIF (albeit with much worse-looking text) than if I do it with Inkscape. It's been a while since I looked at image formats in detail, but if it is simply a matter of massaging the color of the "background" pixels in the GIF, is there a tool that can do this? I changed the document properties from #ffffff00 to #00000000 wondering if that may make a difference, but it doesn't.
Why I care:
I'm trying to create some white text to be composed over a colored background, but I want to be able to control the color of the background via CSS in a web page rather than have to create a separate image for each color I want.
Any ideas/suggestions/information would be appreciated.
Thanks in advance,
ast

Actually, IE has supported PNG for some time now. It's just that only the most recent (or Macintosh) versions support PNG with alpha transparency, but do support PNG with a binary transparent color.

You're absolutely right, Jon, but I have a different definition of "support" than "it puts some pixels on the screen" ;)
What I would expect by "support" (and was what I meant) was that the displayed image quality is not less than the alternatives (the PNG rendering is less than perfect) and that it supports features like alpha transparency if they are part of the specification.
