Pathfinding using Bitmap

Question

Where could I find a good as3 class for Pathfinding, using a bitmap?

The white pixels would be traversable and the not white would be obstacles.

So I could find a node, say, at point (34, 33), (starting point), and make a path (setting pixels colors) to the point (300, 240),(ending point).

Thanks.

You could also call getVector() on the BitmapData to extract the pixel information (see link). You just need to find a library for ASTAR that uses an input vector with values of 0 being blocked. If one doesn't exist, it should be fairly easy to update a existing library like http://www.dauntless.be/astar/ to use uint Vector grids.
