Step 2: The list of cropping items are free, original, square, 3:1, 3:2, 4:3, 5:4, 16:9 in ImageEditor. You can set any crop item as default cropping. In SetToolbarItemVisibility method, disable the remaining items as false.

In the below code snippet, we have set 3:1 as default cropping in ImageEditor and disabled remaining items except 3:1.

C#

public MainPage()
  {
     InitializeComponent();
 
     Editor.Source = ImageSource.FromResource("ImageEditor_GettingStarted.Image.jpg");
 
     Editor.SetToolbarItemVisibility("free,square,original,3:2,4:3,5:4,16:9",false);
  }
