polygon vs path

[Rtc1]

I have some files with <polygon> tags in them. They
display fine, but would be fine if they could be edited
without converting them to a path first. Also some
function to convert back to <polygon> or create
polygons in the first place would be great.

pencil should create polygon, tool below should create
path?

I have written some JavaScript which will examine a <path> element, determine if it is a valid polygon and convert it to a <polygon> element if possible. I wrote it so I can use InkScape to create and edit polygonal shapes, but I want my run-time code to operate on <polygon> elements.

It runs as a command line tool, using the Rhino JavaScript interpreter. It uses env.js to provide a browser-like DOM model and then operates on the SVG Dom.

I plan on making it available as part of an Open Source toolkit for processing SVG at build time. It could possibly be converted to an InkScape Scripting Extension. Let me know if there is any interest.

@sean - I'm currently reviewing old reports and blueprints, and it seems that your path to polygon could be a good answer to https://blueprints.launchpad.net/inkscape/+spec/svg-vector-export.
Could you please give a link to your toolkit or attach it to the bug report? Thanks in advance!

The tools are in an old Google Code project that I had called "surf city":

The particular file that you are interested in is Paths2Shapes.js:

https://code.google.com/p/surfcity/source/browse/trunk/demo/releasetools/js/Paths2Shapes.js

I hope this helps, let me know if you have any questions.

@Sean - Thanks! I'm going to investigate how we could use your tool (or maybe a Python version) in Inkscape.

Any support for the remaining basic shapes <polyline> and <line>?

There's a blueprint for it:
