How to automate recoloring and exporting of the same image for 200 colors?

[XuCxSxMk]

I have an image where I want to recolor a specific object to specific values and then export said image. Now, I would need to do this for around 200 different colors (with the same image) and I am looking for ways to automate this.

From what I've found, macros would be one option but they don't allow parameterized inputs and I did not find a way to edit the macro file itself to duplicate the file and edit the values in there instead. Sadly, Affinity doesn't offer any Python or JSON API.

So, I am at my (inexperienced) wits end and wanted to ask if there are other options I could pursue?

Thanks!

I can’t imagine this can be done in any Affinity app currently.

i would probably try to export as SVG and use any suitable script languages or text editor to change the color codes in a fixed place of that file and save the modified copy of the file under the name of the color.

You may create a vector layer and suitable blend mode (like color).

Neither can I

My tuppence worth

Hard to say without knowing the construction of your image and what output format you need
If the specific object is a vector shape then you could export as svg and use scripting to change colours and write new svgs
If it's a raster image and you want to recolour a region then you could try imagemagick with connected-components

If the image area to colourize is the same for each of the 200 wanted results and varies in the colour value only you might try APub's Data Merge to load the colour from a data source, possibly as image masked in APub by the wanted pixel selection.

Another approach, without Data Merge but Macro: Create a layer (e.g. image) which contains 200 fields each with a wanted colour. Place this below the mask of the area to colourize. Use Macro to move this layer step by step to its next colour field. Save the current result … and repeat move + save.
