[Bug] Zoom causes crash

[nopeless]

Zooming in without image is loaded crashes the application

Null reference error and I believe this is an easy bug to fix. If you are unsure what I am referring to let me know

@me505 If you are interested in this, the project compiles out of the box (fresh clone just compiles straight away). The offending method is here

PicView/src/PicView/UILogic/TransformImage/Zoom.cs

Lines 239 to 288 in 9aea167

 /// <summary> 
 /// Zooms in or out the <see cref="ConfigureWindows.GetMainWindow.MainImage"/> by the given amount. 
 /// </summary> 
 /// <param name="isZoomIn">Determines whether to zoom in or out.</param> 
 internal static void Zoom(bool isZoomIn) 
 { 
     // Disable zoom if cropping tool is active 
     if (UC.GetCroppingTool != null && UC.GetCroppingTool.IsVisible) 
     { 
         return; 
     } 
  
     var currentZoom = ScaleTransform.ScaleX; 
     var zoomSpeed = Settings.Default.ZoomSpeed; 
  
     switch (currentZoom) 
     { 
         // Increase speed based on the current zoom level 
         case > 14 when isZoomIn: 
             return; 
  
         case > 4: 
             zoomSpeed += 1.5; 
             break; 
  
         case > 3.2: 
             zoomSpeed += 1; 
             break; 
  
         case > 1.6: 
             zoomSpeed += 0.5; 
             break; 
     } 
  
     if (!isZoomIn) 
     { 
         zoomSpeed = -zoomSpeed; 
     } 
  
     currentZoom += zoomSpeed; 
     currentZoom = Math.Max(0.09, currentZoom); 
     if (Settings.Default.AvoidZoomingOut && currentZoom < 1.0) 
     { 
         ResetZoom(); 
     } 
     else 
     { 
         Zoom(currentZoom); 
     } 
 } 

Just add a null check

What is this.

Its a lightweight .NET WPF image viewer. Kinda like the "Photos" program that comes with a windows install

Thanks. It will be fixed in next release.
