I suppose this is a bug, or has anybody an idea: I have a transparent canvas and a white drawing. Very simple thing. Now I want to export this as a gif, just like it is: transparent background, white drawing. But this seems to be impossible. I can choose any of the available settings in export dialog (no transparence, index-transparency, alpha-transparency), Fireworks will never export the image correctly. Either I have a total white or a total transparent gif, I even got a white drawing on black background (but can't reproduce it).
System: Mac, Fireworks CS5
Thank you, Michael
Set the Transparency type to Alpha when you export.
