Last patch: 04.04.2021
License: GNU GPL v3
This piece of spaghetti-code, called "vpypetools", is a wrapper to pass (pipe) line elements from InkScape selection (or complete canvas) to vpype.
It allows to run basic commands on the geometry. The converted lines are getting pushed back into InkScape.
vpypetools allows to enable some important adjusters and debugging settings to get the best out of it.
vpypetools is based on
- Aaron Spike's "Flatten Bezier" extension, licensed by GPL v2
- Mark Riedesel's "Apply Transform" extension (https://github.com/Klowner/inkscape-applytransforms), licensed by GPL v2
- a lot of other extensions to rip off the required code pieces ;-)
