`delay`	`uint32_t`	the delay time in milliseconds

Make the animation timeline repeat itself.

void lv_anim_timeline_set_repeat_count(lv_anim_timeline_t *at, uint32_t cnt)

Name	Type	Description
`at`	`lv_anim_timeline_t *`	pointer to the animation timeline.
`cnt`	`uint32_t`	repeat count or `LV_ANIM_REPEAT_INFINITE` for infinite repetition. 0: to disable repetition.

Set a delay before repeating the animation timeline.

void lv_anim_timeline_set_repeat_delay(lv_anim_timeline_t *at, uint32_t delay)

Name	Type	Description
`at`	`lv_anim_timeline_t *`	pointer to the animation timeline.
`delay`	`uint32_t`	delay in milliseconds before repeating the animation timeline.

Name	Type	Description
`at`	`lv_anim_timeline_t *`	pointer to the animation timeline.
`progress`	`uint16_t`	set value 0~~65535 to map 0~~100% animation progress.

Set the user_data of a an animation timeline

void lv_anim_timeline_set_user_data(lv_anim_timeline_t *at, void *user_data)

Name	Type	Description
`at`	`lv_anim_timeline_t *`	pointer to the animation timeline.
`user_data`	`void *`	pointer to any data. Only the pointer will be saved.
