Here is a question I’d love to find the answer to:
-
Suppose you have a Sprite which contains a shape instance within.
-
The sprite is scaled down ( let’s say 50% ), and added to the stage, but the shape it contains is left unscaled.
-
Now, if the shape has CAB enabled, is the cached bitmap rendered at the final screen res, post container transforms ( in this case, the cached bitmap would be 50% smaller than the shape ), OR Is the cached bitmap rendered at 100% the size of the shape, and then downsampled when it is drawn onto the screen?
…why is this relevant?
[COLOR=#333333]For example[/COLOR]:
A) IF it turns out that cached bitmaps resulting from CAB are screen-res ( post all container transforms ), then it might make sense to set CAB to true even on a Bitmap instance, if one of its parent containers is scaled up or down ( so as to minimize the resampling effort, every time the bitmap is drawn to the screen ).
B) In the earlier example, with the unscaled shape within a scaled sprite, IF it turns out that cached bitmaps resulting from CAB are NOT screen-res ( meaning NOT post container transforms), then it might be advantageous to move the shape out of its container and apply the 50% scaling on it directly ( again, to minimize the resampling effort required to draw the cached bitmap onto the screen ).
