This is a plug-in which allows you to specify various mathematical
transformations to apply to images. You still need to understand
and write the specific mathematical transformation that you need
to accomplish the visual effect you desire.

In principle it is possible to do this with a script. Assuming you
had mastered the math given in the josleys.com article you would
know what to do to the pixels. The problem is that finding the value
of a pixel with the Eyedropper, computing something from this value
and then marching the Eyedropper across and down the image to do
the same for all the other pixels would be *extremely* slow.
(However, the Python math library would permit you to do the math.)
It would be faster to write the image data to file in a simple
format like Graphics RAW or Portable Bitmap (.pbm) and process them
with an external program, perhaps one you've authored in a favorite
programming language. Asking someone familiar with plug-in authoring
tools to implement such a thing as a plug-in would be another way
to go.
