MedicalViewerReferenceLineProperties Class

Summary

Represents the class that is used to create the MedicalViewerPlaneCutLine, and adjust to reference line properties of this cell.

Syntax

C#
VB
C++
public class MedicalViewerReferenceLineProperties 
  
Public Class MedicalViewerReferenceLineProperties  
             
            public ref class MedicalViewerReferenceLineProperties  
             

Remarks

To show the reference line of this cell on the other cells correctly, the following properties will need to set by retrieving their values from the DICOM Data Set:
