Clipping Path? A nasty PS thing for jpegs? No good trying to apply PS concepts
to Gimp. If you have not already seen this worth a look.

Ctrl-Shift-click (Command-Shift maybe for Mac) deletes a control point or a
segment between control points

Control points not in the correct place, add as required with Ctrl-click

Gimp is built around plugins and paths are no exception. 

Lots here http://sourceforge.net/projects/gimp-path-tools/files/scripts/  all
python plug-ins

and about 5 down ofn-path-edits.py Comes with documentation on use, although for
joining control points they have to overlap closely.

Still using Gimp 2.8? Time to upgrade to Gimp 2.10 (unless of course unlucky to
have a Mac)

[Gimp-user] How to cut or combine paths in GIMP

2019-01-26 Thread Kjotvi
I am trying to do a simple clipping math in GIMP, and I need to combine a
circular path with a bump out to show part of the image that extends beyond the
circular path. In my experience I would either cut the circle or delete a short
section of the circle, then link the end points of the "bump-out" to the new end
points fo the circular path. Alternatively I could have the "bump-out" overlap
the circle, and merge the two.

I can find no "delete path section", "cut path section", or "merge paths"
language (or anything similar) anywhere in the GIMP manual. How would I go about
accomplishing this?

Additional to the previous:

To add a mask in Gimp Layer -> Mask -> Add Layer Mask

see: https://docs.gimp.org/2.10/en/gimp-layer-mask-add.html

A few ways but say, using Black (full transparency) then Path-to-selection, fill
the selection with white.

Saving as a Gimp .xcf keeps masks, paths, active selections. For an export, png
keeps transparency, You can try exporting as a psd, but as-far-as-I-know while
you get transparency & a layer mask, that is all. No paths transferred.
