Syntax
C#
C++/CLI
public static void LoadJson( 
   this DicomDataSet ds, 
   string fileName, 
   DicomDataSetLoadJsonFlags jsonFlags 
) 
[ExtensionAttribute()] 
public: 
static void LoadJson(  
   DicomDataSet^ ds, 
   String^ fileName, 
   DicomDataSetLoadJsonFlags jsonFlags 
)  

Parameters

ds
The Data Set that will be created and populated with the contents of the DICOM JSON input file

fileName
The name of the input JSON file

jsonFlags
Flags that affect whether to ignore binary or all data from the DICOM JSON input file

Remarks

Use this method to read the contents of a DICOM JSON file. The DICOM JSON file can be created using SaveJson By default, all binary data is read from the DICOM input JSON file, but this behavior can be modified by passing appropriate DicomDataSetLoadJsonFlags

Example
C#
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; 
 
public void LoadJsonExample() 
{ 
   string dicomFileNameIn = Path.Combine(LEAD_VARS.ImagesDir,"DICOM", "image3.dcm"); 
   string jsonFileNameOut = Path.Combine(LEAD_VARS.ImagesDir, "test.json"); 
 
   // Initialize DICOM engine 
   DicomEngine.Startup(); 
 
   DicomDataSet ds = new DicomDataSet(); 
 
   // Load an existing DICOM file 
   ds.Load(dicomFileNameIn, DicomDataSetLoadFlags.None); 
 
   // Save as JSON with no binary data 
   // For the demo, keep the json output file size small by skipping the pixel data 
   const DicomDataSetSaveJsonFlags jsonFlags = DicomDataSetSaveJsonFlags.IgnoreBinaryData | 
                                               DicomDataSetSaveJsonFlags.TrimWhiteSpace; 
   ds.SaveJson(jsonFileNameOut, jsonFlags); 
 
   // Now reload the json file.   
   // Note that there will not be an image because we skipped the pixel data in the save 
   ds.LoadJson(jsonFileNameOut, DicomDataSetLoadJsonFlags.None); 
 
   DicomEngine.Shutdown(); 
}
