How to view Slices in Image Component

[alykhaled]

I used this code to try to view the slice in Image Component
I tried to use the same method from SliceRenderingEditorWindow but it didn't work

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

namespace UnityVolumeRendering
{
    public class SliceImage : MonoBehaviour
    {
        private SlicingPlane[] spawnedPlanes;
        private Image sliceImage;
        // Start is called before the first frame update
        void Start()
        {
            
        }

        // Update is called once per frame
        void Update()
        {
            spawnedPlanes = FindObjectsOfType<SlicingPlane>();
            var sliceImageParent = this.gameObject.transform.GetChild(0).gameObject.transform.GetChild(0).gameObject.transform.GetChild(2).gameObject;
            Debug.Log("Parent name: " + sliceImageParent.name);
            sliceImage = sliceImageParent.GetComponent<Image>();
            if (sliceImage == null)
            {
                Debug.LogError("No Image component found in children of this object");
            }
            else{
                Debug.Log("Image component found");
                Debug.Log("Image component name: " + sliceImage.name);
            }
            if (spawnedPlanes.Length > 0)
            {
                SlicingPlane planeObj = spawnedPlanes[0];
                Material mat = planeObj.GetComponent<MeshRenderer>().sharedMaterial;
                Texture3D tex3D = mat.GetTexture("_DataTex") as Texture3D;

                // Create a new Texture2D with the same format as the Texture3D
                Texture2D tex2D = new Texture2D(tex3D.width, ex3D.height, tex3D.format, tex3D.mipmapCount > 1);

                // Copy the slice from the 3D texture to the 2D texture
                Graphics.CopyTexture(tex3D, 0, 0, tex2D, 0, 0);

                sliceImage.sprite = Sprite.Create(tex2D, new Rect(0, 0, tex2D.width, tex2D.height), new Vector2(0.5f, 0.5f));

            }
        }
    }

}
