bitmap caching question

stephenfinn · 10-24-2005, 11:44 AM

could someone clear up this for me?
does bitmap caching only apply to vector images? that would seem to make sense; a vector is turned into a bitmap then moved much quicker around the screen because the vectors don't have to be worked out every frame. however, i saw this :

which suggests that it works for bitmaps too. can anyone explain this?

bitmaps are drawn to vectors in order to render by the flash player hence that result being acheived

so the png is converted to vectors via the cacheAsBitmap?

everything in flash is converted to vectors, cacheAsBitmap just means that section does not get redrawn. but if it is invalidated you start getting nasty performance issues
