Can we animate the UI image by changing offsets ?

This is what I did:

 public class BackgroundFollow : MonoBehaviour {
     Transform control;
     float current_x_offset = 0;
     public float offset = 0f;
     public float x_pos;
     public float y_pos;
     public float z_pos;
 
     void Awake () {
         control = GameObject.FindGameObjectWithTag ("player").transform;
         Vector3 pos = new Vector3 (control.position.x + x_pos, y_pos, z_pos);
         transform.position = pos;
     }
 
     void Start ()
     {
         SetOffset ();
     }
 
     public void SetOffset ()
     {
         offset = control.position.x - this.transform.position.x;
     }
 
     public void ScrollImage (float amount)
     {
         Vector3 pos = transform.position;
         pos.x = control.position.x - this.offset;
         transform.position = pos;
 
         current_x_offset += amount;
         Vector2 offset = new Vector2 (current_x_offset, 0f);
         this.GetComponent<Renderer>().sharedMaterial.SetTextureOffset ("_MainTex", offset);
     }
 }
