Clutter.Actor.get_paint_volume

### Method

# Clutter Actorget_paint_volume

#### Declaration [src]

    const ClutterPaintVolume*
    clutter_actor_get_paint_volume (
      ClutterActor* self
    )

#### Description [src]

Retrieves the paint volume of the passed `ClutterActor`, or `NULL` when a paint volume can’t be determined.

The paint volume is defined as the 3D space occupied by an actor when being painted.

This function will call the `ClutterActorClass`.get_paint_volume() virtual function of the `ClutterActor` class. Sub-classes of `ClutterActor` should not usually care about overriding the default implementation, unless they are, for instance: painting outside their allocation, or actors with a depth factor (not in terms of `ClutterActor:depth` but real 3D depth).

Note: 2D actors overriding `ClutterActorClass`.get_paint_volume() should ensure that their volume has a depth of 0. (This will be true as long as you don’t call clutter_paint_volume_set_depth().)

#### Return value

Returns: | `ClutterPaintVolume`
| A pointer to a `ClutterPaintVolume`, or `NULL` if no volume could be determined. The returned pointer is not guaranteed to be valid across multiple frames; if you want to keep it, you will need to copy it using clutter_paint_volume_copy().
| The data is owned by the instance.
| The return value can be `NULL`.
