int of pixel and surrounding pixels [message #56032]

Hello,
I am trying to find the intensity of a pixel and its surrounding
pixel.

I have a list of x and y coordinates as my points of interest. I want
to find the intensity at that pixel and the ones surrounding it and
obtain a mean of those 9 pixels. I want to do this for all my
coordinates, so I will be using a for loop to go from one coordinate
to another. Is there a quick way of reading the pixel int of adjacent
pixels so my for loop is not too slow?

Thanks,
RP
