... here's how to use the path as specification for a curves-alike
color mapping:
0. Install Rob Antonishen's "Sample Gradient along Path" Script [1]
1. Create image 256x256 pixels
2. Draw gradient black to white from bottom to top
3. Create the desired curve as a path
4. Create a new gradient via "sample gradient along path"
- with 256 steps and
- sample radius = 1
5. Switch to target image
6. Apply Colors->Map->Gradient Map
not for the faint of heart...
regards,
peter
