Error in --adjust_colors

Software G'MIC
1

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 1.6.0.1.

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 1.6.0.1, so you just need to upgrade to the lastest G’MIC version.

Ok, I will upgrade the version, thanks.
