Assetdatabase.renameasset Renaming file failed

The code to write a unity Editor today will change Format for all Texture selected in the Project Panel and then rename it to XXX. Dither.png then automatically makes the 16-bit compression map mentioned in the previous article

Just started to change Format, but do not know how to rename the resource file, after Google, found the appropriate API:

An empty string "" is returned when the rename succeeds, otherwise an error message is returned

The first two parameters I passed in were full-path, but each time I returned an error

Trying to move asset as a sub directory of a directory that does not exist assets/ui/assets/ui/xxx.png

So I take the second parameter out of the full path, leaving only the new file name. That's it, here's the code.

 
 
 1 [MenuItem("Edit/Transform Texture To Dither")]
 2 static void SetSelectTextureToDither()
 3 {
 4     foreach(Object obj in Selection.GetFiltered(typeof(Object), SelectionMode.Assets))
 5     {
 6         string path = path = AssetDatabase.GetAssetPath(obj); ;
 7         TextureImporter textureImporter = AssetImporter.GetAtPath(path) as TextureImporter;
 8         if (textureImporter == null)
 9             continue;
10 
11         textureImporter.textureFormat = TextureImporterFormat.AutomaticTruecolor;
12         textureImporter.mipmapEnabled = false;
13 
14         AssetDatabase.WriteImportSettingsIfDirty(path);
15         string newPathName = Path.GetFileNameWithoutExtension(path) + ".Dither";
16         string renameRes = AssetDatabase.RenameAsset(path, newPathName);
17         if (renameRes != "")
18             Debug.Log("Fail to rename, err: " + renameRes);
19         AssetDatabase.WriteImportSettingsIfDirty(newPathName);
20     }
21     Debug.Log("Complete transform Texture to Dither!!");
22 }
