Hi,

Is there a good way to get a 2d array of RGB values for a region on the screen? I have some custom algorithms that I want to use to detect shapes. They require arrays of pixels. I see there is a getColor API, I think repeatedly calling it pixel by pixel would be slow for a 100x100 region.

Then getColor() will not take snapshot. It would be faster. Don't forget set usePreviousSnap(false) to release the sanpshot.

I assume it's very fast because it's reading in memory.
