Please implement Custom Color Palette Conversion

[Bogdan]

Hi!

Custom color palette conversion, similar to PNG export options, already available, or similar to Indexed Color Mode in Photoshop, or similar to GMIC-QT filter in GIMP.

For each pixel in an image or layer:
Calculate the the most similar color from a user-defined custom color palette.
Replace the color of that pixel with that similar color.

Thank you!

 

P.S. initial discussion available here:

Do you know that G'MIC also exists as a 8bf-plugin for Photoshop and Affinity Photo too? I usually prefer to use it in GIMP, because I noticed that some filters don't work in Photo or even do it not as fluid as in GIMP. May also be because I used to do it in GIMP for years before I purchased Affinity.
