I use G’MIC with GIMP and I’d like to apply some filters on a bunch of pictures, so I’m trying to do what I did with GIMP but in command line. Using Ubuntu Linux with G’MIC 2.3.3.
I’m trying to use the filter “Sharpen [shock filters]” with its default values but I’m not sure how to. I’ve tried the following:
gmic Tx_wall_stone_01.tga -resize 400%,400% -fx_sharpen_shock -o Tx_wall_stone_01.png
but I get this error:
*** Error *** Command 'fx_sharpen_shock': Undefined argument '$5', in expression '$5' (for 1 argument specified).
I’ve also tried to add values after it (for Amplitude, Edge, etc. −the fileds that are in the dialog in GIMP) but same error with $7 instead of $5.
Looks like I’m missing an argument to the filter but I can’t find a proper description or syntax to use.
