Unity 4.6 UI Touch Detection

Question

Hey, is there a way in Unity 4.6 how to detect whether Touch position is inside UI Rect like this?:

 if (GUITexture.HitTest(Touch.Position)) return true;

I know there's a RectTransform Component but due to Anchors, it's coordinates arent in pixels from bottom-left corner. So I Tried something like this:

 RectTransform SRTrans = this.GetComponent<RectTransform>();
 
             this.TouchAreaRect = new Rect(
                 this.transform.position.x - SRTrans.rect.width / 2,
                 this.transform.position.y - SRTrans.rect.height / 2, 
                 this.transform.position.x + SRTrans.rect.width / 2, 
                 this.transform.position.y + SRTrans.rect.height / 2
                 );

This code is working for one of my UI Images, but it's not working properly for other ones so is there a better solution like GUI Texture had a HitTest Method?

Well, I found out that I made mistake in defining new Rect of course which should be like this:

 this.TouchAreaRect = new Rect(
                 this.transform.position.x - SRTrans.rect.width / 2,
                 this.transform.position.y - SRTrans.rect.height / 2, 
                 SRTrans.rect.width, 
                 SRTrans.rect.height
                 );

I had problems with width & height, I dont know why I was trying to add position to it as well...
