|

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 ;-)
