PathMeasure

class PathMeasure(val gskPathMeasurePointer: <Error class: unknown class><<Error class: unknown class>>)(source)

GskPathMeasure is an object that allows measurements on GskPaths such as determining the length of the path.

Many measuring operations require sampling the path length at intermediate points. Therefore, a GskPathMeasure has a tolerance that determines what precision is required for such approximations.

A GskPathMeasure struct is a reference counted struct and should be treated as opaque.
