BMAP - 08/08/07 03:28
Hey guys/girls,
I was wondering if there was an efficient way of coding a bmap manipulation technique.
What I am trying to achieve is; take a black and white bmap (a square with a white circle), record each pixel position which is white and set its alpha value to 0 (so you end up with a transparent circle). Then you take a larger Bmap and use the values given from the smaller bmap (circle) to effectivly create a transparent circle on the large bmap.
I hope this is understandable.
Thanks in advance.

I expected it to lag a little but its actually pretty good.
