With the new cacheAsBitmap option, is it possible to force the renderer to not redraw while scaling a flattened Sprite/MovieClip? So you basicly get the same performance as scaling a single bitmap?
Right now, scaling a large nested complex movieclip seems to be very expensive and results in a very low FPS.
I believe scaling is triggering a redraw. Do you know if cacheAsBitmap on Flash redraws on scale? Is cacheAsBitmapMatrix required to get the behavior you want? (it is not implemented outside of Flash yet, but it could be)
I do believe cacheAsBitmap also forces a redraw when scaling on flash. However the render cost is lower. cacheAsBitmapMatrix blocks redrawing on flash so that is the desired result. However; this is as far as I know only implemented on mobile yet.
So an implementation of cacheAsBitmapMatrix that would work on desktop also would indeed produce the behavior I’m looking for
I think we need to continue to do testing on the caching algorithm in place, first. Once that’s stable, supporting cacheAsBitmapMatrix probably won’t be terribly complicated
