Pixellate and Create Color Map

[Vasily]

In GIMP,  you can convert an image to pixels of a specified size then generate a color map for the pixels in the image. Can this be done in Photo or Designer? A friend wants to be able to use this feature for creating crochet designs - she's currently using GIMP

Welcome to the Serif Affinity forums, Vasily.

I'm not sure it's the same thing, but perhaps Layer > New Adjustment Layer > Posterize is similar?

AFAI understand it's not exactly the same, even posterization (mostly done via a color quantization) reduces an image to a specified amount of colors, in APh it doesn't draw or place automatically a color map overview of all used image colors here. - I believe the OP is probably more after the visual generation of a used colors table index/overview here.

Thanks! Looks like the solution she's wanting is:

Layer > New Adjustment Layer > Posterize (set level)

Swatches > Create Palette from Document > As Document Palette

Making reusable color palettes out of images should work, placing these together on images needs some better macro facilities.

Yeah, looks like you're right. That's not what Posterization is doing. What about Rasterize ... ? When I select it, I'm not getting any options or a dialog and the help doesn't seem to explain what it's supposed to be doing.

Rasterization just rasters layers (converts to bitmap/pixels). - The before shown is a PS action, so nothing Affinity build-in.

Posterization and quantization are similar filters ...

... though probably not what your friend want's for creating crochet designs.

If you can show here one of those in Gimp created examples (as JPG/PNG etc.)  we can possibly give you some better help.

I think I figured it out -- it's pixelate that she'll need:

1. Filters > Distort > Pixelate
2. Select level of pixellation desired
3. Swatches > Create Palette from Document > As Document Palette

Ok then she want's to have instead a document related color palette, reusable swatch colors from all used colors in an image/drawing.

Yep - she can find matching colors of wool and refer to the pixelated image as she crochets her design (she's also a graphic designer so crocheting isn't the only reason she's looking at Affinity)

Thanks man!

I lost some time looking for this. 

Swatches tools for palete color will be great for my work.
