Question

I’ve got a flex component which works pretty well but unfortunately turns into a
disaster once used in a datagroup item renderer of about 40-50 items.

Essentially it uses bitmapdata to take screenshot of a fully-rendered webpage in
mx:HTML (this version of webkit rocks btw, miles better than flex 3).

The code is pretty self-explanatory I think.

I’ve optimized it all I could, browsed, search for answers and already trimmed
it down a lot, I’m desparate to reduce the memory usage (about 600mb after 100
draw)

The Garbage collector has little effect.

Thanks!

You need to call BitmapData.dispose() when you’re done with them, you can’t just chuck them away and hope they get collected. Sometimes they will, but often not :'(
