I have been experimenting with the getColorBoundsRect function in Flash, with interesting results. This is a really powerful tool. It allows us to analyze the colour information on the stage and isolate specific colors. In this example I am am finding all the red within the image and replacing it with green. It may not be the prettiest example, but it shows you exactly what I mean.
It’s not as simple as telling flash to find all the red, but rather it determines the region that it is in, afterwards I then subdivide that region into smaller sections and then analyze it again. This repeats until it has only the red.
Just click the analyze button and wait a second while it determines where the red is.
