Annotation viewer crop WPF

[deedubya]

Hi,

I am using latest version of Annotation viewer in WPF. I have tools for annotations and crop and can detect when the annotation ends but cannot seen to find the event which relates to the completion of the crop (WpfCropSelectionTool) as I would like to automatically turn off this tool once it has been exectued.

Thanks

Hi,

If you want to know when WpfCropSelectionTool visual tool executed WpfCropSelectionTool.Crop method, you need to do the following steps:

• Create MyWpfCropSelectionTool class, which is derived from WpfCropSelectionTool class, and override WpfCropSelectionTool.Crop method:

  Code: Select all

  public class MyCropTool : WpfCropSelectionTool
  {
      public override void Crop()
      {
          base.Crop();
  
          ImageViewer.VisualTool = null;
      }
  }

• Use MyWpfCropSelectionTool class in image viewer.

Best regards, Alexander
