Declaration [src]
gfloat
clutter_paint_volume_get_depth (
const ClutterPaintVolume* pv
)
Description [src]
Retrieves the depth of the volume’s, axis aligned, bounding box.
In other words; this takes into account what actor’s coordinate
space pv belongs too and conceptually fits an axis aligned box
around the volume. It returns the size of that bounding box as
measured along the z-axis.
If, for example, clutter_actor_get_transformed_paint_volume()
is used to transform a 2D child actor that is 100px wide, 100px
high and 0px deep into container coordinates then the depth might
not simply be 0px if the child actor has a 3D rotation applied to it.
Remember: if clutter_actor_get_transformed_paint_volume() is
used then the transformed volume will be defined relative to the
container actor and in container coordinates a 2D child actor
can have a 3D bounding volume.
There are no accuracy guarantees for the reported depth, except that it must always be greater than, or equal to, the actor’s depth. This is because actors may report simple, loose fitting paint volumes for efficiency.
