Well, if the background is sufficiently low contrast, then you can fake it by rendering the text (with antialiasing) on a surface with a colour that is approximately the background colour. Then you make all the pixels that still have that background colour (100%) transparent. The blended pixels will be a bit off (since they're blended with an approximate, monochrome background rather than the real background) but if the contrast is low enough then that won't be noticeable. At least, that was my theory. And it seems to work: http://nova.student.utwente.nl/~lourens/gfx/opengraphics/traversal_logo_3.gif I've also made the background a little darker and separated it out: http://nova.student.utwente.nl/~lourens/gfx/opengraphics/background.jpg Lourens
