Yes, it’s rolled in one command.
This is already added. It’s gmic h +pal
. David_Tschumperle has added the specialization of +command.
This I don’t know about. With my Premade Palette GUI filter, the help documentation provided there might look ugly. And that’s also why I have added so many palettes. There’s rainbow palettes, there’s gradients palettes, there’s hardware-based palette, there’s software palette, there’s existing game palette, there’s desaturated palette, there’s palette of each color, and there’s speciality palette like Human Faces. Basically just about everything though I wish I could do some more.
