Darktable and GMic

Software darktable
1

Right now I use some older GIMP. Upgrading to current is “too difficult”, my system doesn’t meet the current gimp requirements.

I’m using DT 3.8.1 and it runs fine on my system. Right now, I have to export to TIFF, open in GIMP, do my GMic, then export the TIFF, the reimport the TIFF in DT and do my final adjustments: resizing, sharpening…

Is there some plugin to use the GMic-qt? I’m looking for the GMic pencils, B&W and distortions.

BTW, I use regularly the RL output sharpen.

Thanks

There is a lua plugin that’ll call gmic after export. Perhaps you can modify it to meet your needs.

I’ve looked/googled around, including: https://github.com/darktable-org/lua-scripts/blob/master/README.md

and I can’t see it. Can you provide me with a link and I’ll attempt to modify it.

Thanks

Looks like you want to do 2 things differently from the script:

  1. Adjust image mid-pipe, not at export.
  2. Use G’MIC-Qt stand-alone, not CLI.

Note that since the last release, G’MIC-Qt also has command line options which can be interesting (for example to pre-select a particular filter).
See supported options here : gmic-qt/STANDALONE.md at master · c-koi/gmic-qt · GitHub
