Image.fillOrigin

Description

Controls the origin point of the Fill process. Value means different things with each fill method.

You should cast to the appropriate origin type: Image.OriginHorizontal, Image.OriginVertical, Image.Origin90, Image.Origin180 or [[Image.Origin360] depending on the Image.Fillmethod.

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

[RequireComponent(typeof(Image))]
public class ImageOriginCycle : MonoBehaviour 
{
	void OnEnable () 
	{
		Image image = GetComponent<Image>();
		string fillOriginName = "";

		switch ((Image.FillMethod) image.fillMethod)
		{
			case Image.FillMethod.Horizontal:
				fillOriginName = ((Image.OriginHorizontal) image.fillOrigin).ToString();
				break;
			case Image.FillMethod.Vertical:
				fillOriginName = ((Image.OriginVertical) image.fillOrigin).ToString();
				break;
			case Image.FillMethod.Radial90:
				
				fillOriginName = ((Image.Origin90) image.fillOrigin).ToString();
				break;
			case Image.FillMethod.Radial180:
				
				fillOriginName = ((Image.Origin180) image.fillOrigin).ToString();
				break;
			case Image.FillMethod.Radial360:
				fillOriginName = ((Image.Origin360) image.fillOrigin).ToString();
				break;
		}
		Debug.Log (string.Format("{0} is using {1} fill method with the origin on {2}", name, image.fillMethod, fillOriginName));
	}
}

Note: This will only have any effect if the Image.type is set to Image.Type.Filled.
