Error in --adjust_colors


Hi, I am trying to change the contrast of a image with this command : gmic image1.jpg --adjust_colors 0,30,0,0,30 -o image2.jpg,90 but this error appears: Unknown command or filename ‘–adjust_colors’.
I am using version

Any help ?, thanks.

I just looked at the doc, and the first command in the Colors Manipulation section used to be --apply_channels, and now it’s --adjust_colors. Methinks this command was added after version, so you just need to upgrade to the lastest G’MIC version.


Ok, I will upgrade the version, thanks.
