Class
ClutterDesaturateEffect
Description [src]
class Clutter.DesaturateEffect : Clutter.OffscreenEffect
{
/* No available fields */
}A desaturation effect
ClutterDesaturateEffect is a sub-class of ClutterEffect that
desaturates the color of an actor and its contents. The strength
of the desaturation effect is controllable and animatable through
the ClutterDesaturateEffect:factor property.
Constructors
clutter_desaturate_effect_new
Creates a new ClutterDesaturateEffect to be used with
clutter_actor_add_effect().
Instance methods
clutter_desaturate_effect_set_factor
Sets the desaturation factor for effect, with 0.0 being “do not desaturate”
and 1.0 being “fully desaturate”.
Methods inherited from ClutterOffscreenEffect (5)
clutter_offscreen_effect_create_texture
Calls the Clutter.OffscreenEffectClass.create_texture virtual function of the effect.
clutter_offscreen_effect_get_pipeline
Retrieves the pipeline used as a render target for the offscreen
buffer created by effect.
clutter_offscreen_effect_get_target_size
Retrieves the size of the offscreen buffer used by effect to
paint the actor to which it has been applied.
clutter_offscreen_effect_get_texture
Retrieves the texture used as a render target for the offscreen
buffer created by effect.
clutter_offscreen_effect_paint_target
Calls the Clutter.OffscreenEffectClass.paint_target virtual function of the effect.
Methods inherited from ClutterEffect (1)
clutter_effect_queue_repaint
Queues a repaint of the effect. The effect can detect when the ‘paint’
method is called as a result of this function because it will not
have the CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag set. In that case the
effect is free to assume that the actor has not changed its
appearance since the last time it was painted so it doesn’t need to
call clutter_actor_continue_paint() if it can draw a cached
image. This is mostly intended for effects that are using a
%CoglOffscreen to redirect the actor (such as
%ClutterOffscreenEffect). In that case the effect can save a bit of
rendering time by painting the cached texture without causing the
entire actor to be painted.
Methods inherited from ClutterActorMeta (5)
clutter_actor_meta_get_actor
Retrieves a pointer to the ClutterActor that owns meta.
clutter_actor_meta_get_enabled
Retrieves whether meta is enabled.
clutter_actor_meta_get_name
Retrieves the name set using clutter_actor_meta_set_name().
clutter_actor_meta_set_enabled
Sets whether meta should be enabled or not.
clutter_actor_meta_set_name
Sets the name of meta.
