Apache OpenOffice (AOO) Bugzilla – Issue 113186
basegfx::tools' isConvex() test fails for self-intersecting polygons
Last modified: 2017-05-20 11:35:09 UTC
The current test for polygon convexity (basegfx::tools::isConvex) gives wrong results for some self- intersecting polygons. The test is currently only used to accelerate the triangulation of clip regions which self-intersect rarely. If the test is to be used for general testing though it needs to give proper results for self-intersecting polygons too.
