Creating a new image from an image input in IDL [message #70808]

After typing this line of code:
IMAGE=READ_TIFF(FILEPATH('/bin/butterfly.tiff'))
help, IMAGE

I get the output
IMAGE BYTE = Array[3, 4800, 6000]

Now I want to write a computer program to systematically loop through
each of the n x n pixels of the image and to use a coordinate system
in pixel units to compute new coordinates based on the formula theta_s
= theta - (size parameter of your choosing in units of
pixels)*theta_hat.

The vector theta_s tells me where to look in the original image to
extract intensity information which will then store in my image array.
I will use a bilinear scheme when assigning new intensity values that
will be stored for my newly created image array theta. Now I have no
idea how to even begin. I was looking for stuff online and I was
looking at help manuals but all efforts proved futile. Let me know of
your suggestions and I greatly appreciate your help on this.
