Not sure what you mean, but the attached code will save your image in a matrix like

[r, g, b, x, y]

one row for every pixel. If that's not what you want, give an example after you read this:

How is that different than indexing into the array using basic subscripts? If there is a specific nontrivial thing you want, you have to describe it.
