Working with bitmaps

Flash Player 9 and later, Adobe AIR 1.0 and later

In addition to its vector drawing capabilities, ActionScript 3.0 includes the ability to create bitmap images or manipulate the pixel data of external bitmap images that are loaded into a SWF. With the ability to access and change individual pixel values, you can create your own filter-like image effects and use the built-in noise functions to create textures and random noise.
