Hi!

I know, how i can calculate the position of the mouse in x and y
coordinates, but I don't know, how i can get information wether the colour
is blue, red or green about the picture on this x and y coordinates.

Also I don't know, how I can make around the Mouse a circle, and calculate
all the pixels (in the picture) wether the colour is blue, red or green (how
many pixels are in the circle)

Does anybody know something how i can interrogate this?

Thanks in advanced

Pierre
