Thanks Is there any way to process just one RGB channel in the distort equations code?

Thanks, but I am specifically looking for the actual code to do it with the "procedural textures" tool. I've updated the question to make it more clear.

Is this possible with procedural textures code? Say the procedure is currently operating on pixel (1,2) but I want to know the red values of the pixels at (1,1) ánd (1,3) - how do I get that data? Is there any sort of array structure I can use to store and index a lot of different values? Can I directly access the pixel data of the image as an array? Also is there a way of shifting the entire image or perhaps the current row/column by n pixels procedurally (like "affine" but in code)? If not then please consider this a feature request.
