Hi :)
Does anyone know wether it's possible to spread the pixels colors
considering
the normal vector of the selection curve ?
Maybe you could implement a script to do the following:
- Border selection with a width of 1 pixel.
- Copy.
- Paste as new layer.
- Scale this new layer to be one pixel bigger.
- Paste as new layer, scale to be two pixels bigger.
- Paste as new layer, scale to be three pixels bigger.
- ... Repeat as many times as needed.
- Flatten the image or combine layers.
Not sure if that is something similar to what you want to do, but it would
be curious to see how it looks like :).
I would do it differently, using a path (which is very easily obtained
from the selection):
- walk the path by fixed steps:
- at each step:
-- sample the color on the path
-- compute the normal segment (with length=width) at the point a
half-step before (which is the "after" of the previous step)
-- compute the normal segment at the point a half-step after
-- create a quadrangle path from these two segments
-- create a selection from that path
-- bucket-fill with the color sampled above
Might be a bit slow :)
