Re: [NTG-context] METAPOST: How do I get this 'max' cutafter to work?

Hans’ example also works with “intersectionpoint”: the differences between intersectionpoint and intersection_point are minimal except if there is no intersection at all. The trick is that Hans does not use cutafter. cutafter is designed to cut off as little as possible, it is a cutbefore on both paths reversed. So, uses the last intersection point of the paths, and in this case it will therefore use the top of the arrowhead. In contrast, intersectionpoint finds the first intersection on the non-reversed paths, which is the base of the arrowhead. Alternatively (in this case), you could move the arrowhead up a tiny amount, so that there is only one intersection between the connection and arrowHead. Best wishes, Taco
