I have the image:
I = [1 1 1 3 3 3 3 3
1 1 1 1 3 3 3 3
1 1 1 1 3 3 3 3
1 1 1 1 2 2 2 3
1 1 1 1 2 2 2 3
1 1 1 1 2 2 2 3
1 1 1 1 2 2 2 2];
How can i fit a square of size say two pixels around the point (4,6)? Many thanks for your help/suggestions.

If you are asking to draw a square on the screen then use rectangle()

"i fit a square of size say two pixels"
"my actual intention is to get the area of the square"
So if your square is 2 pixels by 2 pixels, then your area will be 4 pixels. Why do you even need to ask?
