public class PathMeasure

`GskPathMeasure` is an object that allows measurements on `GskPath`s 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.

Namespace: Gsk

Creation methods:

public PathMeasure (Path path)
Creates a measure object for the given path with the default tolerance.
public PathMeasure.with_tolerance (Path path, float tolerance)
Creates a measure object for the given path and tolerance.

Methods:

public unowned PathMeasure @ref ()
Increases the reference count of a `GskPathMeasure` by one.
public float get_length ()
Gets the length of the path being measured.
public unowned Path get_path ()
Returns the path that the measure was created for.
public bool get_point (float distance, out unowned PathPoint result)
Sets result to the point at the given distance into the path.
public float get_tolerance ()
Returns the tolerance that the measure was created with.
public void unref ()
Decreases the reference count of a `GskPathMeasure` by one.
