Got it working. I definitely learned a lot from this one.
Thanks for all your help Saulgoode.
By the way i decided to not use channels for my selections in the filter. I just created a new from visible and ran effects with that selection. Works fine. Just have to make sure you are not using a filled bg layer when you run it or the filter fills in the entire drawable. Here is the final code and an example after running it.
Location is Rod>Reptile Skin Effect
Works best on thinner fonts i think but you can experiment.
To save just select all from the window copy and paste into notepad ++ or the like and save as reptile-skin-effect_RD.scm in your scripts folder.
Enjoy!
