"A BitmapData object can be drawn to the screen by a Bitmap object in one of two ways: by using the vector renderer as a fill-bitmap shape, or by using a faster pixel-copying routine. The pixel-copying routine is substantially faster than the vector renderer, but the Bitmap object must meet certain conditions to use it:
-No stretching, rotation, or skewing can be applied to the Bitmap object. -No color transform can be applied to the Bitmap object. -No blend mode can be applied to the Bitmap object. -No clipping can be done through mask layers or setMask() methods. -The image itself cannot be a mask. -The destination coordinates must be on a whole pixel boundary." The above is from the help file. 1) the "pixel-copying routine" is referring to BitmapData.copyPixels() ? 2) What does it mean by "the Bitmap object must meet certain conditions to use it" ? (a) "the Bitmap object" is referring to the source bitmap for copyPixels? or the target bitmap to be drawn? (b) We cannot use copyPixels when the source bitmap has been scaled etc ? Or after the copyPixel(), the target bitmap can no longer be scaled etc? or just the speed would be affected?
