Summary

The flags that affect how the JSON metadata is generated.

Syntax

C++/CLI

public DicomDataSetSaveJsonFlags SaveJsonFlags { get; set; }

public:  
   property DicomDataSetSaveJsonFlags^ SaveJsonFlags 
   { 
      DicomDataSetSaveJsonFlags^ get() 
      void set(DicomDataSetSaveJsonFlags^ value) 
   }

Property Value

Flags that affect how the JSON metadata is generated.

Remarks

These flags are used with the StoreMetadata and GenerateMetadata methods.
