While editing an image (i.e. while there's a new version of it every few seconds), I would like to continuously see what the newest version would look like after running an external script on it (for example dithering by ImageMagick).
One possible solution is this:
- Use an image editor that can auto-save the image after every change (here's how to do this in Photoshop for example)
- Write a program that runs the external script and displays its result whenever autosaves happen (i.e. whenever the file changes)
Is there a more straightforward solution to integrate the external script into my workflow? Maybe GIMP or Photoshop allow using the external script "as an adjustment layer" (i.e. non-destructive editing) or so? (Is that even possible? Maybe in Photoshop; not in Krita; GIMP doesn't even have built-in non-destructive editing)
