Dithering in actionscript 3.0

I had to convert some images from color to monochrome while keeping as much detail as possible therefore I had to dither images.

The closest thing in as3 I found was this experiment on Sephiroth's website. You can read his blog entry here.

These are some pretty nice experiments, but not quite what I needed. So there was some research going on and the result is this:

Some of the algorithms were ported in as3 from pseudo code and explanations found in the following resources: this, this , this, this, this, and this

This port would not be possible without the help of Iulia Nastasoiu - Java developer, singer, dancer and ocasional philosopher and Teodor Stoenescu - programmer, drummer and general wise ass. Check out Pandrea for a heavy dose of 'mioritic metal'





I found the image in one of the sites listed above and I see it as a 'Hello World!' of the dithering algorithms

[EDIT]

Ralph Hauwert, a very important contributor to the Papervision3D project ( thank you for the cool materials and shaders ) has his own Dithering experiments.

There might be some confusion, so I'll try to break it down. I needed a monochrome dithered image resulting from any given image, so my version is thought for only one color. Ralph's version supports colour. For further info on his implementation I advise you to read his blog entry here

You can find his classes on Google Code
