Encoding Property

Summary

Gets a value that indicates how the DICOM element data is encoded.

Syntax

C++/CLI

public ElementDataType Encoding { get; set; }

public:  
   property ElementDataType^ Encoding 
   { 
      ElementDataType^ get() 
      void set(ElementDataType^ value) 
   }

Property Value

A value that indicates how the DICOM element data is encoded.

Remarks

Modifying Encoding changes how the DICOM element value is decoded.
