The original script is for LightZone and GIMP, which works nicely, from GIMP to LZ and back to GIMP
So my changes works nicely from GIMP to Darktable, but to get back from Darktable to GIMP again, I got an error
Any idea, help? I can't think anymore my head gets narrow vision now and is on fire
the code I did some change for Darktable:
Original code of Lightzone.py

Version:
0.8c Made it compatible with Windows, macOS, and Linux
0.8b Made it specific for LightZone
0.8 Made it specific to Nik Collection
0.7 fixed file save bug where all files were png regardless of extension
0.6 modified to allow for a returned layer that is a different size
than the saved layer for
0.5 file extension parameter in program list.
0.4 modified to support many optional programs.
this script is modelled after the mm extern LabCurves trace plugin
by Michael Munzert http://www.mm-log.com/lab-curves-gimp
and thanks to the folds at gimp-chat has grown a bit ;)
