BulkDataUri Property (SaveXmlData)

Summary

Gets or sets the bulk data URI that is about to be written.

Syntax

C++

public string BulkDataUri {get; set;}

Public Property BulkDataUri As String

public: 
property String^ BulkDataUri { 
   String^ get(); 
   void set (    String^ ); 
}

Property Value

The bulk data URI that is about to be written.

Remarks

If BulkDataUri is passed to SaveXml, a dummy URI is generated for each binary data element that is about to be written, and is returned in BulkDataUri. This can be changed to a custom URI by setting the BulkDataUri to the desired URI.

Example

This example will load a sample DICOM data set, then save it in the Native DICOM Model XML format specified in PS3.19.A.1 of the DICOM specification, changing each URI to a custom URI.
