public void MedicalViewerScaleExample1()  {     MedicalViewerForm myForm = GetMedicalControl();     MedicalViewer medicalViewer = myForm.Viewer;     MedicalViewerScale scale = (MedicalViewerScale)medicalViewer.GetActionProperties(MedicalViewerActionType.Scale, 0);     scale.Scale *= 2;     medicalViewer.SetActionProperties(MedicalViewerActionType.Scale, scale, 0);     myForm.ShowDialog();  }

To set the properties of the scale action, call the SetActionProperties method, and to retrieve the properties call the GetActionProperties method.

The mouse controls the actions as follows:

• Click and hold the mouse to start the effect. When the assigned mouse button is released the action ends.
• Dragging the mouse down enlarges the image.
• Dragging the mouse up shrinks the image.
