GIMP Gradient Script

[RobA]

A while back I wanted to create some hypsometric gradients in GIMP. There a quite a few out there (usually as jpegs) and being a lazy guy I wrote a script rather than messing about with the gradient editor (attached).

The script gets loaded into the gradient menu (accessible in the gradient palette, click the < arrow in the right hand corner). Chose the image and layer (drawable), dial the segments in the gradient, and select if you want the segments to be blended or stepped.

The program will sample the entire source vertically, and horizontally depending on the segments selected.

Here is a source image I ran the script on:
hypso_humid_boost.png

and here is the resultant gradient that was created, opened in the gradient editor:

And a resultant fill with that gradient:

Unchecking "smooth" will make the gradient colour steps. I have limited it to 256 steps, but you could change she script to more quite easily (the limit for GIMP gradients is 1024).
