- add options: - ToDo:
- replace trimmed paths by bezier paths (calculating lengths and required t parameter) - add more comments
- filter/remove overlapping/duplicates in - add more debug output
- in original selection (not working bezier but for straight line segments!) We can use another extension for it - add documentation at online page
- split bezier - add statistics about type counts and path lengths (before/after sub splitting/trimming)
- ... - add options:
- maybe option: convert abs path to rel path - replace trimmed paths by bezier paths (calculating lengths and required t parameter)
- maybe option: convert rel path to abs path - filter/remove overlapping/duplicates in
replacedelement.path = replacedelement.path.to_absolute().to_superpath().to_path() - in original selection (not working bezier but for straight line segments!) We can use another extension for it
- maybe option: break apart while keeping relative/absolute commands (more complex and not sure if we have a great advantage having this) - split bezier
