Dear Inkscape Team, I did a merge request for an updated bool LPE. See the merge request comments. What I still need is a method to check if a PathVector is closed or open. I want to issue an error message if the operands are not as expected, but I couldn't find a way to do this. Jabier wrote that there is some isClosed() function, but I couldn't find anything around a PathVector. Any help with this is appreciated. Best regards, Michael
