Weighted Blend
#1
Is there a plugin or a means to weight a shaped blend to certain predetermined points instead of the normal center of the shape?

Not directly, but you can:

1) apply a plain linear black to white gradient

   

2) Use Curves (or, in the simpler cases, Levels) to map to another gradient.

   

In other words, you can see the initial gradient as indicating how far you are from the border, and the Curves as mapping that distance from the border in to a grey level.

3) Once you are done, you can use Color>Map>Gradient map to transform that grayscale gradient in to any gradient:

Thanks for the help, but that will not work. I will keep trying to write a script to do the work.

Maybe as a starting point for a script. RMA_path_blend.scm Uses two paths and there are snags - the paths must have the same number of nodes + empty space to fill in.

If its a script, you can replace the Curves by a Gradient map with a gradient created on the fly.

Otherwise show an example of what you want to do.

Something like this: http://gimp-wrapmap.sourceforge.net/

Or this: https://sourceforge.net/projects/gimp-pa...p/download
