Compare pixel color in fastloops

[Phanto]

I'm using HWA, latest version, and using the Pixel Object extension crashes my game so that doesn't seem to be an alternative.
What I want to do is compare every pixel in the frame (250x186), and if the pixel is green, save 1 to an array. If the pixel is red, save 2. Blue 3. White 0.
So what I've got now is a fastloop going through the frame and write values into the array. but I' haven't got anything to check the color of the pixel representing xy values.
I searched the forums and found someone mention "GetRBGat" but I can't find it. Screen Pixel doesn't seem to be able to compare color as a condition.

Use the Surface object off-screen and just grab the entire frame area.

LB, that doesn't work in HWA, unfortunately. I would need an HWA SDK so I could add support for it...

Ah! Good idea. I can see that it has a "get color from pixel", very nice

Another question though, since I've never used the surface object before and it has so many operations -- how do you grab the entire frame area and paste it into the Surface object?

EDIT: what exactly doesn't work?
