Inkscape CloseCurves extension English support forum

Сообщение Nick »

If you have any questions click here to register. You can choose English interface there.

This is an Inkscape extension that closes all open curves in the selection.
It may be useful when you want to use curves in other programs such OpenOffice. OpenOffice wont fill path if it isn't closed one. Also if you convert text to curve, you can see some trash in the outline because curves are not closed (see attached pictures).

Close curves inkscape extension
This extension works with paths. It modifies path's d parameter. It adds a 'z' just before each 'm' if it's not the first one in the line or there's already 'z' before it.


Instalation: Unpack files from attached archive to /usr/share/inkscape/extensions/. Extension appears at Extension->Modify path.

Any comments and contributions are welcome :)!
