Hi all,
I'm now doing something with BitmapData class. Now I have a bitmap
data with many colors in it. I want to implement some function like Eraser
in photo processing tools. User can choose some area and click a button to
remove all the colors in that area (set all colors to transparent). The area
user choose is round, so it seems I can't use some inner function which all
of them require the area is Rect. Is there any way I can deal with such
problem?
Thanks a lot.
