Hello, I've been trying around to use AlphaBlend with bitmaps and found out that when I repeatedly call it on the same surface the bitmap accumulates due to the fact that the blit is done onto the previous result instead of clearing it out. Well, how is it cleared out anyway if the framework does not do it ? Is it a matter of remembering the original background ? If so, what if the background changes ? And what if the bitmap changes the position on the surface ? Well, I am really not sure how to make use if I look at these questions/problems but maybe someone knows. Thanks in advance.
