Lets hope that OP is not using that one then.
Hey Everyone, I wanted to thank all of you for taking the time to provide input on my question.
Sorry about the image provided being a JPEG. I didn't think about the ramifications regarding color. I am still using Gimp 2.8 and my posterize seemed to be working correctly.
I'm looking for a way to automate the process. I would like to create a python-fu script to create the original image, posterize it, and then split it into separate layers. I would then like to bump map each layer and create a drop shadow for each layer.
Ultimately, I am trying to create the following type image (and then automate the process).
Thanks again for your useful comments!!!
The technique I explained with thresholded layer masks is inspired by one of my scripts, which is demonstrated here:
http://gimpchat.com/viewtopic.php?f=9&t=9311
The script is here: https://sourceforge.net/projects/gimp-to...y/download
Some doc at the bottom of this page: http://gimp-tools.sourceforge.net/tools.shtml
80% of the script can be reused. In fact you just have to remove the pixellation step and the tiles images and use hard-wired values for the thresholds (or your own algorithm/heuristic). You have to add the drop-shadow (easy to script) and perhaps the smoothing of the curve (but then upscaling noise should do it).
