Extension for InkScape 1.X
|
|
|
|
This extension converts an SVG path's d attribute the following way: find each V (vertical line) and each H (horizontal line) and replace it by a generic line (L type).
|
|
A lot of extensions do not work with V and H, but with L commands. So this is just a helper extension for other extensions :-)
|
|
|
|
Example conversion:
|
|
from: M 60.403,71.0937 V 89.268022 135.773
|
|
to: M 60.403 71.0937 L 60.403 89.268 L 60.403 135.773
