Bisection: make the value smaller when the half circle did not touch the border (like in your picture), make it larger when it did touch. Eventually I reached a value where only one leg touched. 14.04 is a long time ago: conceivable that there were changes in rasterization since then. Still I consider it rather likely that you'll find such a half-touching value. I did not try to automate this. -- David Kastrup -- cairo mailing list [email protected] https://lists.cairographics.org/mailman/listinfo/cairo
