- the useful links you have given me point to 'stuff' that's applicable to Windows. I do have that OS, but my primary desktop is a Linux based one. Are there equivalent links for resynthesizer for Linux?
It depends on the linux you are using. Which one is it ?
If you can get this one to work https://www.gimp-forum.net/Thread-Gimp-3...9#pid44349 then it includes resynthesizer and the gmic plugins Otherwise you need a regular installation with a libgimp-dev to compile it.
Quote:- the link to the 'how to' mp4 you gave is most useful. Running it in VLC allows me to follow it closely and in detail. When I do so (under Linux) in GIMP 3.0.4 (a .deb AppImage version to which you kindly provided a link) and click on the final 'ok' in G'MIC repair/in-paint no processing takes place: I'm just left with my image and the lasso selection around the painted-over wires. Obviously it's a user error; from my description could you possibly suggest what it is that I am going wrong?
I put in the selection because for a large image the plugin takes forever. Was the selection inverted perhaps and selected everything except the wires ? Worth a check.
You do need pure red (R=100 % G=0 B=0 ) for the mask, a bit off and the plugin does not work. Use the pencil tool so there is no anti-aliasing which leaves a border.
If having trouble, make a smaller crop around some wires and try without making a selection, as a trial. Try using some of the other inpaint filters, some work better than others.
You identified the problem exactly - thank you:
- My 'red' was a little bit off.
- The selection was inverted (not easy to spot in GIMP) even though I was sure that I had corrected it (in fact I had inverted it).
Having corrected these errors, the technique works fine and is a little easier/quicker to use than the method I have used in Photoshop. Obviously there is a bit of messing about with the clone tool at the termination of overhead cables, where they run behind a part of a building, for example. Then, even with extreme care, there is some unintended 'healing' of the building edge.
And, as you suggested, the G'MIC plug-in doesn't need the creation of a selection with the lasso tool. The test images I tried were relatively small (40MB tiff) and I have a reasonable mid-range processor (9th gen i7) so the processing took less than a second or so without a selection.
So now, thanks to your guidance, I know how to process this common problem (overhead lines) in my images, in GIMP, allowing me to avoid using any Adobe products.
