UnityEngine.UI.Image change Texture2D

Hey I'm trying to assign a Texture2D to a UI Image control but can't find a proper way -_-

Code (CSharp):

1.       var pix = sourceTex.GetPixels(width * panel.X, height * panel.Y, width, height);
2.       Texture2D destTex = new Texture2D(width, height);
3.       destTex.SetPixels(pix);
4.       destTex.Apply();
5.  
6.       // panel.Image is a UnityEngine.UI.Image
7.       panel.Image.material.mainTexture = destTex;

halp?

 

in case anyone is looking for a solution:

Code (CSharp):

1. panel.Image.sprite = Sprite.Create(destTex, new Rect(0, 0, width, height), Vector2.zero);
