Honestly, I don’t use the G’MIC plugin. The preview is unreliable and the GUI syntax isn’t well documented. However, most of the world interacts with G’MIC commands that way (in filter form). My plan is to get better acquainted with the plugin and its interaction with the hosts.
Based on the website, the plugin is available for GIMP, Krita, Paint.NET and OpenFX (e.g., Natron), and as a standalone. Going as official a route as possible with the software is probably the best strategy for testing. I am a casual user of GIMP and have no experience with the other apps. Hope I can get some guidance on their installation and testing.
Don’t know how far I will explore. Feel free to make this thread your own like what the G’MIC exercises thread has become: for everyone to pitch in and ask questions.
BTW, I use Windows 10 and my personal reasons for starting this thread is to improve the plugin variant of my CLI commands. E.g., I find using layers as input images, etc., challenging.
