public class Path

Describes lines and curves that are more complex than simple rectangles.

Paths can used for rendering (filling or stroking) and for animations (e.g. as trajectories).

`GskPath` is an immutable, opaque, reference-counted struct. After creation, you cannot change the types it represents. Instead, new `GskPath` objects have to be created. The [struct@Gsk.PathBuilder] structure is meant to help in this endeavor.

Conceptually, a path consists of zero or more contours (continuous, connected curves), each of which may or may not be closed. Contours are typically constructed from Bézier segments.

Static methods:

public static Path? parse (string string)

Methods:

public bool @foreach (PathForeachFlags flags, PathForeachFunc func)
Calls func for every operation of the path.
public unowned Path @ref ()
Increases the reference count of a path by one.
public bool equal (Path path2)
Returns whether two paths have identical structure.
public bool foreach_intersection (Path? path2, PathIntersectionFunc func)
Finds intersections between two paths.
public bool get_bounds (out Rect bounds)
Computes the bounds of the given path.
public bool get_closest_point (Point point, float threshold, out unowned PathPoint result, out float distance)
Computes the closest point on the path to the given point.
public bool get_end_point (out unowned PathPoint result)
Gets the end point of the path.
public bool get_next (ref PathPoint point)
Moves point to the next vertex.
public bool get_previous (ref PathPoint point)
Moves point to the previous vertex.
public bool get_start_point (out unowned PathPoint result)

public bool get_stroke_bounds (Stroke stroke, out Rect bounds)
Computes the bounds for stroking the given path with the given parameters.
public bool get_tight_bounds (out Rect bounds)
Computes the tight bounds of the given path.
public bool in_fill (Point point, FillRule fill_rule)
Returns whether a point is inside the fill area of a path.
public bool is_closed ()
Returns if the path represents a single closed contour.
public bool is_empty ()
Checks if the path is empty, i.
public void print (StringBuilder string)
Converts the path into a human-readable representation.
public void to_cairo (Context cr)
Appends the path to a cairo context for drawing with Cairo.
public string to_string ()
Converts the path into a human-readable string.
public void unref ()
Decreases the reference count of a path by one.
