The G’MIC page at https://gmic.eu/gallery/ provides example images for the various filters, artistic for example, along with the G’MIC CLI command that produced the image. Try as I might, including “gmic help” I haven’t been able to find documentation on what any of the parameters mean - the result being that the parameters are just meaningless strings of numbers.
I did find the page at https://gmic.eu/tutorial/command-guide.shtml which has links to what looks like could have been the documentation but none of the links (all of which lead to pages on particularart.com) work.
I also note that there is not a 1:1 relationship between the filters identified on the gallery page and the filters in the G’MIC GIMP plugin. For example, following is the command from the gallery page for running the sketchbw filter:
gmic tiger.png +sketchbw 1 reverse blur[-1] 3 blend[-2,-1] overlay
but here is the parameter string that is output to the GMIC log when the filter is run from GIMP:
fx_sketchbw 3,45,180,30,1.75,0.02,0.5,0.75,0.1,0.7,3,6,0,1,4,0,50,50
I do note that the above parm list does mostly match up with the filter’s dialog in GIMP but not perfectly. And the two versions of the command appear to have nothing in common.
Any help on locating a source clarifying/documenting the meaning of the command line parameters would be greatly appreciated.
Thanks.
