What you need to do is pass the color to one of these algorithms at
run time. Getting the color is a UI problem--use tinker or the like.

Hi!
I have an image with certain areas that are bounded by color
boundaries.
I'd like to have a program that flood fills the region with a certain
threshold after the user clicks on the image and records the pixels
that
belong to this area.
I found out that Gimp's flood fill tool with threshold 48 does exactly
what I want. Has anyone got a clue on what is the algorithm they used?
All I could find after short Googling are flood-fill algorithms where
you give the target color explicitly which I do not want to do,
because
I don't know it and also it varies slightly across the border.
Is there any implementation I might refer to other than downloading
Gimp's source code and trying to make sense out of it?
Thanks!
