hi all!

i'm developing a multimedia program,
like a mp3 player, and i need to have
a visualization. i have the necessary
effects (blur, alpha blending), but i
wanna know how can i draw a transparent
line(x1,y1,x2,y2,color) with windows'
bitblt function (right now my vis creates
a black rect over the skin, and that sure
looks ugly)

any kind of help is appreciated. docs,
codes, etc.

I remember seeing an article in PC Magazine about this. I'll see if I can dig it up for you tonight.
