## Detailed Description

Animation_View widget is designed to show and play animation of vector graphics based content.

It hides all efl_canvas_vg details but just open an API to read vector data from file. Also, it implements details of animation control methods of Vector.

Vector data could contain static or animatable vector elements including animation infomation. Currently approved vector data file format is svg, json and eet. Only json(known for Lottie file as well) and eet could contains animation infomation, currently Animation_View is supporting.

This widget emits the following signals, besides the ones sent from Animation View.

- "play,start": animation is just started.
- "play,repeat": animation is just repeated.
- "play,done": animation is just finished.
- "play,pause": animation is just paused.
- "play,resume": animation is just resumed.
- "play,stop": animation is just stopped.
- "play,update": animation is updated to the next frame.

## Function Documentation

## ◆ elm_animation_view_auto_play_set()

void elm_animation_view_auto_play_set | ( | Elm_Animation_View * | obj,
|  | Eina_Bool | auto_play
| ) |  |

Animation will be started automatically when it's possible.

If elm_animation_view_auto_play_get is `true`, animation will be started when it's readied. The condition of `auto` play is when animation view opened file successfully, yet to play it plus when the object is visible. If animation view is disabled, invisible, it turns to pause state then resume animation when it's visible again.

Warning
  This auto play will be only affected to the next animation source. So must be called before setting animation file

Set auto play mode of an animation view object. `true` Enable auto play mode, disable otherwise

Parameters

  [in] | obj | The object.
  [in] | auto_play | Auto play mode, Default value is `false`
