Gradient fill?

[Azarkant]

Best way I could describe it? I want to fill an rea with a gradient of colors so that I can find what parts of said are are closer to one edge verses another. I don't want to brute force it and I want to be able to do 8+ colors. Is there a plug in that would do that?

Also; the gradient tool does not do what I need it to do

You could try this one:

Or even better what IHaveNoName posted (last 2 paragraphs, using Pencil to create color blocks and resize):

If I understood correctly, you want to have a distance from object edge -gradient.

 

Two ways I can think of: first one, G'MIC-Qt has an effect specifically for this. Effects->Advanced->G'MIC-Qt->Rendering->Gradient [Custom Shape] and choose opaque pixels. It has up to 10 stop gradients.

 

Second: The Edge Shader plugin, but it has only 2 colors. You could use it to do a grayscale distance, then use Gradient Mapping from Pyrochild's plugin pack to map it to a freeform gradient (the Gradient Mapping plugin has strange gamma - maybe it uses linear color instead of sRGB or vice versa since 2.2 gamma corrects it - so you may need to adjust levels on the grayscale version a little).

 

 

->(G'MIC) or -> (Edge Shader+Gradient Mapping)
