Hi Martin,
I'm using 0.92 at the moment. New extensions API, is there already some documentation about that? On one of the Inkscape forums I also read something about C++ extensions being supported in the (near) future?
Back to the question, I'm not sure why I'm getting that FutureWarning. I assumed that the last argument of inkex.etree.SubElement is a node (formatted as a dictionary), and that self.selected[self.options.ids[0]] gives me such an object. Apparently, one of these assumptions is not correct?
Best,
Pieter
Hi Pieter,
Are you using the old inkscape 0.92 extensions or the new inkscape 1.0
extensions API (in trunk and gitlab.com/inkscape/extentions/)
The basics are right, you need to duplicate the object and any children
(for instance in case of text). Transforms can be applied ontop of any
existing transformation.
Best Regards, Martin Owens
