I like reading it however, the writing seems to be somewhat weird while using the IE6 website broswer. This blog truly is marvellous.

I think that you should write more on this topic, it might not be a lesser known subject but generally people are not enough to speak on such topics. To the next.

There are some "optimized" pieces in flash player that works better than other. Images/filters likely uses some parallel calculations nice catch.

But, I wonder 1) if there's an Actionscript implementation anywhere, and 2) how it'd fare in this test regarding speed 3) assume just a couple of on/off state of what you did with the bitmapdata. Maybe not, though. Seems like a sparse matrix could be useful in this type of solution.

So yes, I'm sure it could be optimized ;). Anyway, glad to have added to the pot. See you at MAX! I wanted to imitate your BitmapData method thus the three ByteArrays.

I also modified your code to use writeBoolean() and readBoolean() instead of writeByte() and readByte(). I did brief testing and I think that squeezed a little more speed out of it (but I could be wrong). I also didn't create the comparison ByteArray like you had in your code, since I don't think that was really needed. @Alex – I updated the test app to include a test that uses ByteArray.
