PathPoint

gsk.path_point.PathPoint is an opaque type representing a point on a path.

It can be queried for properties of the path at that point, such as its tangent or its curvature.

To obtain a gsk.path_point.PathPoint, use gsk.path.Path.getClosestPoint, gsk.path.Path.getStartPoint, gsk.path.Path.getEndPoint or gsk.path_measure.PathMeasure.getPoint.

Note that gsk.path_point.PathPoint structs are meant to be stack-allocated, and don't hold a reference to the path object they are obtained from. It is the callers responsibility to keep a reference to the path as long as the gsk.path_point.PathPoint is used.

class PathPoint : Boxed {

int compare(gsk.path_point.PathPoint point2);

gsk.path_point.PathPoint copy();

bool equal(gsk.path_point.PathPoint point2);

float getCurvature(gsk.path.Path path, gsk.types.PathDirection direction, graphene.point.Point center);

float getDistance(gsk.path_measure.PathMeasure measure);

void getPosition(gsk.path.Path path, graphene.point.Point position);

float getRotation(gsk.path.Path path, gsk.types.PathDirection direction);

void getTangent(gsk.path.Path path, gsk.types.PathDirection direction, graphene.vec2.Vec2 tangent);

}

Functions

compare int compare(gsk.path_point.PathPoint point2): Returns whether point1 is before or after point2.
copy gsk.path_point.PathPoint copy()
equal bool equal(gsk.path_point.PathPoint point2): Returns whether the two path points refer to the same location on all paths.
getCurvature float getCurvature(gsk.path.Path path, gsk.types.PathDirection direction, graphene.point.Point center): Calculates the curvature of the path at the point.
getDistance float getDistance(gsk.path_measure.PathMeasure measure): Returns the distance from the beginning of the path to point.
getPosition void getPosition(gsk.path.Path path, graphene.point.Point position): Gets the position of the point.
getRotation float getRotation(gsk.path.Path path, gsk.types.PathDirection direction): Gets the direction of the tangent at a given point.
