Line Merging (Combine Paths)

Merge lines whose endings and starts overlap or are very close. By default, linemerge considers both directions of a stroke. If there is no additional start of a stroke within the provided tolerance, it also checks for ending points of strokes and uses them in reverse. You can use the --no-flip to disable this reversing behaviour and preserve the stroke direction from the input. By default, gaps of maximum 0.05mm are considered for merging.  Also check out vpype Free Mode which can do the same and more.
