These extensions provide information on a path.
This extension measures the length of a path, printing the length alongside the path. A dialog allows many options to be set including Font size, Offset (the distance the text is moved away from the path), Precision (number of decimal places shown), Scale Factor, and Length Unit.
This extension draws the handle lines that one would see if editing the nodes of a path. It would be of more use if it included the drawing of the handle and node symbols.
This extension numbers the nodes of a path. It is useful for creating an old-fashioned Connect-the-Dots puzzle. (It is also an example of how to access the path data in an SVG file for writing your own extension.) The original path is turned into a path with no stroke but with dot markers. The dots are then numbered.
The size of the numbers and the size of the dot markers can be specified.
