BulkDataUri Property

Summary

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

Syntax

C++/CLI

public string BulkDataUri { get; set; }

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 SaveJson, 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

using Leadtools.Dicom; 
using Leadtools.Dicom.Common; 
using Leadtools.Dicom.Common.Extensions; 
using Leadtools; 
using Leadtools.Dicom.Common.Linq.BasicDirectory; 
using Leadtools.Dicom.Common.DataTypes; 
 
using Leadtools.Codecs;

   string dicomFileNameIn = Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "IMAGE3.dcm"); 
   string xmlFileNameOut = Path.Combine(LEAD_VARS.ImagesDir, "test.json"); 
 
   DicomEngine.Startup(); 
 
   DicomDataSet ds = new DicomDataSet(); 
 
   // Load an existing DICOM file 
   ds.Load(dicomFileNameIn, DicomDataSetLoadFlags.None); 
 
   // Keep the JSON output file size small by writing binary data as BulkDataUri  
   // The URI written is modified in the callback 
   ds.SaveJson(xmlFileNameOut, DicomDataSetSaveJsonFlags.BulkDataUri, MySaveJsonCallback); 
 
   DicomEngine.Shutdown(); 
}
