Bitmapdata heavy use - memory disaster (spark / fb4)

I have a flex component that works really well but sadly turns into a disaster that was once used in an item renderer of roughly 40-50 items.

Basically it uses bitmapdata to take a screenshot of a fully rendered web page in mx: HTML (this version of webkit rock btw, miles are better than flex 3).

The code is pretty self explanatory I think.

I optimized everything I could, browsing, looking for answers and already truncating this a lot, I desparate to reduce memory usage (about 600mb after 100 draw)

The garbage collector has little effect.

Thank! Nic

You need to call BitmapData.dispose()

when you're done with them, you can't just drop them and hope they get collected. Sometimes they will, but often not: '(

will event listeners hang on because of the strong link? Try removing listeners or using weak links. See if this helps

Have you ever given orders smallBMD

? You may want to make sure they don't accumulate in memory lingering after use, since you create a new one every time it is called passoire_completeHandler

without deleting the previous one (as far as I can see).
