Function Documentation

compositor_dot_transition_app_fetch_get()

const CompositorTransition * compositor_dot_transition_app_fetch_get

(

void

)

Get the dot transition shown when leaving the app fetch screen.

Returns

Transition, or NULL if app-to-app transitions should be skipped.

compositor_dot_transition_timeline_get()

const CompositorTransition * compositor_dot_transition_timeline_get	(	bool	timeline_is_future,
		bool	timeline_is_destination
	)

Get the dot transition into or out of the timeline.

Parameters

timeline_is_future	Whether the timeline shows the future (otherwise the past).
timeline_is_destination	Whether the transition goes to the timeline.

Returns

Transition, or NULL if app-to-app transitions should be skipped.

compositor_dot_transitions_collapsing_ring_animation_update()

void compositor_dot_transitions_collapsing_ring_animation_update	(	GContext *	ctx,
		uint32_t	distance_normalized,
		GColor	outer_ring_color,
		GColor	inner_ring_color
	)

Draw a ring collapsing from the display edges to a dot at its center.

Parameters

ctx	Graphics context to draw into; the ring is centered in its clip box.
distance_normalized	Animation progress, 0 to ANIMATION_NORMALIZED_MAX.
outer_ring_color	Color of the collapsing outer ring.
inner_ring_color	Color of the thin ring along its inner edge.
