[closed]how to match boxcollider2d size with image after preserv aspect?

I found my answer:

Hope anyone interested would get this help

 void SetBoxCollider()
     {
         RectTransform itemRectTransform = this.gameObject.GetComponent<RectTransform>();
         // strech box collider
         BoxCollider2D itemBoxCollider2D =  itemRectTransform.gameObject.GetComponent<BoxCollider2D>();
         if (itemBoxCollider2D != null)
         {
             Image image = itemRectTransform.gameObject.GetComponent<Image>();
 
             if (image.preserveAspect) {
                 
                 var originalW = (int)(image.sprite.rect.width);
                 var originalH = (int)(image.sprite.rect.height);
 
                 var currentW = image.rectTransform.rect.width;
                 var currentH = image.rectTransform.rect.height;
 
                 var ratio = Mathf.Min (currentW / originalW, currentH / originalH);
 
                 var newW = image.sprite.rect.width * ratio;
                 var newH = image.sprite.rect.height * ratio;
 
                 itemBoxCollider2D.size = new Vector2 (newW, newH);
             } else {
 
                 itemBoxCollider2D.size = image.rectTransform.rect.size;
 
             }
         }
     }
