大家都知道rawimage比image功能少，而且省资源，所以好多时候都会用到rawimage，但是想给rawimage加button等component时候，做一些功能就需要换成image，手动删除有点麻烦，所以就写了个工具。源码放下面 ，有需要自取。

using UnityEngine;
using UnityEngine.UI;
using UnityEditor;

public class ImageSwitch : EditorWindow
{
    [MenuItem("Tools/Image RawImage 互换")]
    static void Open()
    {
        GetWindow<ImageSwitch>("Image 互换").minSize = new Vector2(180, 50);
    }

    bool isRaw = false, isIma = false;
    private void OnGUI()
    {
        GameObject[] oldgs = Selection.gameObjects;
        foreach (GameObject item in oldgs)
        {
            if (item.GetComponent<RawImage>() == null)
            {
                isRaw = false;
                break;
            }
            else
            {
                isRaw = true;
            }
        }
        foreach (GameObject item in oldgs)
        {
            if (item.GetComponent<Image>() == null)
            {
                isIma = false;
                break;
            }
            else
            {
                isIma = true;
            }
        }
        if (Selection.gameObjects.Length == 0)
        {
            isRaw = isIma = false;
        }


        EditorGUI.BeginDisabledGroup(!isRaw);
        if (GUILayout.Button("将 RawImage 替换成 Image"))
        {
            foreach (GameObject item in oldgs)
            {
                string path = AssetDatabase.GetAssetPath(item.GetComponent<RawImage>().texture);
                DestroyImmediate(item.GetComponent<RawImage>(), false);
                item.AddComponent<Image>().sprite = AssetDatabase.LoadAssetAtPath<Sprite>(path);
            }

        }
        EditorGUI.EndDisabledGroup();





        EditorGUI.BeginDisabledGroup(!isIma);
        if (GUILayout.Button("将 Image 替换成 RawImage"))
        {
            foreach (GameObject item in oldgs)
            {
                string path = AssetDatabase.GetAssetPath(item.GetComponent<Image>().sprite);
                DestroyImmediate(item.GetComponent<Image>(), false);
                item.AddComponent<RawImage>().texture = AssetDatabase.LoadAssetAtPath<Texture>(path);
            }
        }
        EditorGUI.EndDisabledGroup();
    }
}

脚本需要放在Editor文件夹下，文件名叫ImageSwitch.cs。打开位置在菜单栏Tools/Image RawImage 互换。
