BitBlt transparancy question?
I've been searchin for 3 hours now with no result so I figured it was time to ask..:)
I have a color bitmap, picturing a dog on a blue background.
The window, which I want to copy the dog into, pictures a nice lawn with many many nice green trees.
The question is, can I copy the dog into the window *without* changing the background, that is, everything blue in the bitmap with the dog will not contribute to anything in the window it is copied into...
I mean as a result I will have a nice picture of a dog walkin around in the park, and not a park and a "cut in" dog in a little square in the middle...?
...cause this is all I get from the BitBlt-func.
thanks a bunch:)
