The overall task is to generate images for charaktertokens in Virtual Tabletop Software (Roll20 in my case) I have existing Artwork (mostly Fullbody) for Characters, Monster etc that needs to be processed.

So there is a big list of source images. For each of these i want:

  • enhance contrast
  • change the style to look a bit more cartoonic (Posterize and add a Outline)
  • mark a square selection to define which part should be used in the token
  • The result of operations above should then combined with two predefined images:
    • background layer below
    • some kind of frame a layer above.

Are there any ready to use Software that can do this with minimal manual operation?

Are there normal Image Editing programs that can be scripted? I tested BIMP which looks good but cannot do the individual selection.

I’m aware that there exists several Batch Image Editor programs, but i seems that none of them can do an individual manual crop/cutout per individual image.

  • So you want an app that's half-automatic for a bunch of actions and half-manual for only one? Why not simply run automation for contrast/cartoonic look, then manually crop the results in any app and lastly run another automation for combining with other predefined images? I don't think it's much slower than the app just opening the pictures automatically for you to let you crop them.

  • Yes that's the solution i will choose, if nothing more comfortable exist. I am aware that my task is very specific, but opening the processed files from Step 1/2 sorting the layers crop, export and then do this several hundred times, doesn't sound attractive for me. Feb 26 at 18:55
