Resolved GUI.DrawTexture / EditorGUI.DrawPreviewTexture not working

Hello

So im trying to display a simple texture inside a custom editor window.
My needs are simple, its just a texture, and it needs to draw in OnGui().

So i tried both;
GUI.DrawTexture()
and
EditorGUI.DrawPreviewTexture()

neither seems to work.
I looked in the forums and other sources, and what i could find is that im doing nothing wrong, yet i keep getting either a black box, or nothing.

Here is my code;

Code (CSharp):

1. using UnityEditor;
2. using UnityEngine;
3. using System.IO;
4.  
5. public class MyEditorWindow : EditorWindow {
6.     [MenuItem("Window/Custom Windows/My Editor Window")]
7.     private static void ShowWindow() {
8.         var window = GetWindow<MyEditorWindow>();
9.         window.titleContent = new GUIContent("My Editor Window");
10.         window.Show();
11.     }
12.     // The texture in question
13.     private Texture2D texture;
14.     // Load the texture in OnEnable()
15.     private void OnEnable() {
16.         texture = LoadImage("Assets/texture.bmp");
17.     }
18.     // Function to load a texture
19.     private static Texture2D LoadImage(string path) {
20.         // Load the referenced image into memory as bytes
21.         byte[] ImageBytes = File.ReadAllBytes(path);
22.         // Create a new Texture2D
23.         var returner = new Texture2D(2, 2);
24.         // Load the bytes into it
25.         returner.LoadImage(ImageBytes, false);
26.         // return the Texture2D.
27.         return returner;
28.     }
29.     // Where the magic is supposed to happen
30.     private void OnGUI() {
31.         GUI.DrawTexture(new Rect(0, 0, 50,50), texture);
32.         EditorGUI.DrawPreviewTexture(new Rect(0, 50, 50,50), texture);
33.     }
34.     // Just to make shure we are refreshing
35.     private void OnInspectorUpdate() {
36.         Repaint();
37.     }
38. }

 

Oof, i found the problem. Apparently unity simply hates bitmaps... Swapping file format to png solved it...
