2、UniGifImage Components

UniGifImage Component source code, see Demo engineering )
Create a RawImage, Hang up UniGifImage Components , This will automatically hang up UniGifImageAspectController Components , as follows :
 Insert picture description here
UniGifImage Components provide the following main interfaces :

// Set up gif, The coroutine is called internally SetGifFromUrlCoroutine,url Support http/https And local paths , The local path is from StreamingAssets Folder read 
public void SetGifFromUrl(string url, bool autoPlay = true)
// Set up gif
public IEnumerator SetGifFromUrlCoroutine(string url, bool autoPlay = true)
// Play 
public void Play()
// stop it 
public void Stop()
// Pause 
public void Pause()
// continue 
public void Resume()

Set it up UniGifImage Parameters of components :

Write a test script

using System.Collections;
using UnityEngine;
using UnityEngine.UI;
/// <summary>
/// gif Show tests 
/// </summary>
public class UniGifTest : MonoBehaviour
{

public InputField gifUrlInput;
public UniGifImage gifImage;
public Button loadBtn;
public Button playBtn;
public Button stopBtn;
public Button pauseBtn;
public Button resumeBtn;
/// <summary>
/// lock 
/// </summary>
private bool m_mutex;
private void Start()
{

loadBtn.onClick.AddListener(() =>
{

if (m_mutex || gifImage == null || string.IsNullOrEmpty(gifUrlInput.text))
{

return;
}
m_mutex = true;
StartCoroutine(ViewGifCoroutine());
});
playBtn.onClick.AddListener(() => {
 gifImage.Play(); });
stopBtn.onClick.AddListener(() => {
 gifImage.Stop(); });
pauseBtn.onClick.AddListener(() => {
 gifImage.Pause(); });
resumeBtn.onClick.AddListener(() => {
 gifImage.Resume(); });
}
private IEnumerator ViewGifCoroutine()
{

yield return StartCoroutine(gifImage.SetGifFromUrlCoroutine(gifUrlInput.text));
m_mutex = false;
}
}

Create a UniGifTest An empty object , Hang up UniGifTest Script , Assignment parameter object , as follows :
