Background - Foreground - how to work on the separation?

[saint_m]

good day dear friends - good day dear gimp-experts,


hello everyone:  i am currently workin on a solution - "saving the foreground - gettin rid of the background: which approach" - you would choose here!?

i am currently working on a litte image where i want to set the lines in the foreground - free from the background.
I have to solve the task - with GIMP: Well i think that this must be possible - i could imagine that we can do this with the help and the work of some "layers" - see the image-

There are a few ways for this. One way to try is:

(1) Colors -> Auto -> White Balance ( the connecting lines are very faint and probably will not show on a light background)
(2) Bucket Fill using Affected Area = Fill whole selection Fill Type = FG color Mode = Color erase.
(3) Set the Background (BG) color as required.
(4) Image -> Flatten Image (this replaces any transparency with the BG color)
