I'm trying to do some image recognition. Before I can start I need to capture the colors within a specified area, and record them within a document.   So I started small with a 7x7 box. You can see the plots below, 0,0 being where your mouse is.   -3,3  -2,3  -1,3  0,3  1,3  2,3  3,3 -3,2  -2,2  -1,2  0,2  1,2  2,2  3,2 -3,1  -2,1  -1,1  0,1  1,1  2,1  3,1 -3,0  -2,0  -1,0  0,0  1,0  2,0  3,0 -3,-1 -2,-1 -1,-1 0,-1 1,-1 2,-1 3,-1 -3,-2 -2,-2 -1,-2 0,-2 1,-2 2,-2 3,-2 -3,-3 -2,-3 -1
