Inkscape Extensions

This is a working list of all known external Inkscape extensions, with a link to where it can be downloaded (and misc notes). It's part of a project to have all or as many extensions as possible available on the website (https://inkscape.org/en/download/addons/). So it will be changing over time.

Note that they may not all be working. Also this list does Not include the extensions listed on this page: http://wiki.inkscape.org/wiki/index.php/Extension_repository. It also does not include new extensions (since this page was created) which were directly uploaded to the website. (I.e. - These 3 pages together contain the vast majority of known Inkscape extensions. Although ~suv's list might be considered the most comprehensive: https://gist.github.com/su-v/9965739

If anyone knows of extensions which are not in any of these 3 places, please let us know (via Docs mailing list: http://lists.sourceforge.net/mailman/listinfo/inkscape-docs) (or any other way you might alreay know of - I had to remove my contact info here, because of increased spam)

not sure?	http://www.inkscapeforum.com/viewtopic.php?p=89409#p89409	just noticed this on a forum - seems to be an improved version, but I'm not sure which extension it improves / from brynn - as I interpret the comments, the op has some extensions that he's made for himself, and this is an improved version of one of them - it doesn't sound like he's made any others publicly available, but might like to - I might try to PM and ask
O-Scape	http://www.nopesport.com/news/1343-o-scape-free-orienteering-mapping-software and https://sourceforge.net/projects/o-scape/	it's said to work with 0.48, extension set for mapping for orienteering
	The following seem to be "personal" extensions. It's not clear whether they are made for wide use or not, or whether they work or not. Or they may duplicate others in this list.

Scale to Size	https://github.com/vovythevov/inskcape_extensions	doesn't work, syntax errors, broken variables and options. Started to fix, idea is interesting. Intends to use the measure path extension to change a path's length (following curves) to a given value (i.e. measures it, then shrinks or grows it by a factor). Doesn't use units, not sure what the length will be in the end when it works.

The following extensions are included in Inkscape 0.91:
EQTeXSVG	https://github.com/julienvitard/eqtexsvg	newer version available on author's page

Scour	http://www.codedread.com/scour/	already included in Inkscape 0.91 and previous versions as Save as -> Optimized SVG
The following are questionable. They either call themselves extensions (or plugins) but don't have INX files, or they're in a language I can't read. One claims to be a repository of extensions but is empty. But I thought worth a mention, just in case. You can decide :-)
