Q: GDI text and the associated alpha

[mikkel]

I want to create an image containing some text. I want to construct
the image data for the text with the TextOut function. I need the
alpha (blending) channel also because the image is later composed
with other images. My problem is that it seems like Windows uses
different alpha values depending on the background color on which
the text is drawn. Does anybody know if this is the case or if there
is another way of getting the text and alpha.

Thanks in advance
