This plug-in allows you to specify a number of random points to select with.
Plug-in Menu Location:
Python-Fu/Select Random Zigzag...
- Have an image opened with active layer(s).
- Run Plug-in (
Python-Fu/Select Random Zigzag...). Choose number of points to randomly select from. Click OK to run.
- Now you have a random zigzag selection (alternating positive and negative space) to work with.
Here I have 2 layers (different images), then I used the plug-in to make a selection and simply clear/delete the selected area.
