this is a follow-up to LP Bug 415079. https://bugs.launchpad.net/inkscape/+bug/415079 I'd like to propose a patch to deal with occasional (multiple) circular loops in the Spiro Spline LPE. The patch consists of a re-application of a common clamp which is normally applied to the angles, but which appears to need to be re-applied at the final stage of the calculation. I've tested this offline in a standalone calculation to confirm that it works. I wonder if someone would be willing to test this directly in Inkscape. http://www.nabble.com/file/p25015469/spiro.diff spiro.diff -- View this message in context: http://www.nabble.com/proposed-patch-for-Spiro-spline-LPE-tp25015469p2501...
