performance question: runtime bitmaps vs. pngs

hi there,

i was wondering if creating and using bitmaps from vector images at runtime yields the same performance advante as using "real" bitmpas like pngs...

any ideas?

yes, externally loaded or runtime generated bitmaps are treated the same, the only difference is that you use more memory by having both the vector and the bitmap versions in memory, im talking about drawing a sprite or movieclip with vector graphics to a bitmapdata object, im not sure about the cacheAsBitmap option though

ah, ok. but i do not have to keep the the vector in memory.
i do:

Code:

---

var spr:SuperGreatSomethingSprite=new SuperGreatSomethingSprite()
var bmd:BitmapData=new Bitmapdata(spr.width,spr.height,true,0)
bmd.draw(spr);
var bmp:Bitmap=new Bitmap(bmd);
addChild(bmp);
spr=null

---

this way there should be no wasted memory, no?

yes the sprite will be cleaned from memory by the garbage collector after some time if you have no more references to it
