BufferedImage in as3?

Is there a class similar to the BufferedImage class in java for as3? It needs to be able to set a certain pixel to a colour inside it, because i've managed to make light (finally) but i need this class to make it lagless

I'm not familiar with the class, but a brief look makes it seem that it is very similar to AS3's BitmapData, perhaps? I've done some testing with that and you can change pixels as desired.

would i be able to calculate where pixels needed to go with translucency then paste 1 image to the screen? i'll look it up...
It appears i can't use translucency Thanks for the pointer, by the way There probably is a way, only i don't have much time to look, ill check again later

You're looking for Bitmap and BitmapData.

The latter contains the actual image data and provides some methods to manipulate it. The former is a wrapper for the data you can put in the display list.

The page above points to some example and tutorials. Look under 'Learn More', before the properties listing.

Also, I've been playing around with BitmapData, and even made a sets of Custom Blocks for that. I've just put them on Forge as "Bitmap Utils", but beware - I haven't really documented them. ^^'
