I use the gmiclib for windows plateform, some of the effects listed in gimp_plugin,but not fond in the reference.
such as:
gimp_charcoal
anyone knows how to use those in command tool??

#gmic -input sample.jpg --gimp_charcoal -output result.jpg

thanks!

To know what G'MIC command is called by the GIMP plug-in, try setting 'Output Messages' -> 'Verbose (layer name)',
the output layer name will contain the command that has been called. You should be then able to run the same filter from the command line or
from a call to libgmic.

thanks for your kindness, you solved my question.
