Prokoudine suggested there ought to be way to heal wires (or a scratch or a linear or curved feature) in images by healing a path drawn along the wire.
My first thought was:
But apparently select from path won't select a path that isn't closed (a path that starts and ends on the same point.) Or else it closes the path for you and then selects inside the closed path, which is not what is wanted in this case. Is there a way to select a one pixel wide bitmap from a path?
Another way? :
Brush Tool -> hard edged, 20 pixel
Path>Stroke with Eraser, emulate brush dynamics
But that leaves the context altered, it is a pain to program in the context and alpha save/restore?
Also I wonder, could this be programmed with GIMPscripter?
The first recipe could be (if Select>FromPath worked as needed in this case.)
The second, probably not because GIMPscripter won't let you add an alpha channel conditionally, and so forth.
Its a case where if you know GIMP well, you know these recipes and don't need a specific plugin programmed to do it.
But also, it might work better if the path was healed in segments, instead of all at once. For that, you might want a plugin to iterate over the segments.
Or maybe the suggestion is that you ought to be able to stroke with the heal tool (the resynthesizer?) as you can stroke with the heal tool with context aware fill in PS. See http://www.youtube.com/watch?v=o_dC-FkW4mw
