Method

ClutterActorapply_relative_transform_to_point

Declaration [src]

void
clutter_actor_apply_relative_transform_to_point (
  ClutterActor* self,
  ClutterActor* ancestor,
  const graphene_point3d_t* point,
  graphene_point3d_t* vertex
)

Description [src]

Transforms point in coordinates relative to the actor into ancestor-relative coordinates using the relevant transform stack (i.e. scale, rotation, etc).

If ancestor is NULL the ancestor will be the ClutterStage. In this case, the coordinates returned will be the coordinates on the stage before the projection is applied. This is different from the behaviour of clutter_actor_apply_transform_to_point().

Parameters

ancestor

Type: ClutterActor

A ClutterActor ancestor, or NULL to use the default ClutterStage.

The argument can be NULL.

The data is owned by the caller of the method.

point

Type: graphene_point3d_t

A point as #graphene_point3d_t.

The data is owned by the caller of the method.

vertex

Type: graphene_point3d_t

The translated #graphene_point3d_t.

The argument will be set by the function.

The returned data is owned by the instance.
