GMIC filter plugin
G'Mic or GREYC's Magic for Image Computing is an opensource filter framework, or, it is an extra program you can download to have access to a whole lot of image filters.
Krita has had G'Mic integration for a long time, but this is its most stable incarnation.
You set it up as following:
- First download the proper krita plugin from the G'Mic website.
- Then, unzip and place it somewhere you can find it.
- Go to and set G'MIC to the filepath there.
- Then restart Krita.
