Have a look at the information on grid coverage (GIS speak for raster).
There is a sample operation that you can use to extract the values into your
own array.
I will point out that this is not the usual way of doing things; normally
people set up a chain of operations and the system is smart enough to only
pull enough pixels through the chain to get the answer.
A good example to look at in the code base (for messing around with values) is
the raster to vector operation (because it looks hard at every pixel to see if
it is an edge).

Achieve unprecedented app performance and reliability
What every C/C++ and Fortran developer should know.
Learn how Intel has extended the reach of its next-generation tools
to help boost performance applications - inlcuding clusters.
