I have a Bitmap where I can draw on. After some seconds I want to let the drawing fade away and blend over to the original picture/bitmap.
Can I do this with the blend mode by drawing the original bitmap on it? I tried something like this and of course it isn't right. Just copying the alpha channel if I get the documentation right.
dstBitmap = new Bitmap(dstBitmapData);
I want to put some percentage to the destination bitmap. So that after doing this some frames the original picture will be visible. As the user can interrupt this by start drawing again I want to use the BitmapData object dstBitmapData.
