public void LoadXml( 
   string file
)

'Declaration

Public Overloads Sub LoadXml( _
   ByVal file As String _
)

'Usage

Dim instance As DicomContextGroupTable
Dim file As String
 
instance.LoadXml(file)

public void LoadXml( 
   string file
)

 function Leadtools.Dicom.DicomContextGroupTable.LoadXml(String)( 
   file 
)

public:
void LoadXml( 
   String^ file
)

Parameters

file: string that contains the name of the XML file containing the context groups to load.

Quickly and easily customize the DICOM Context Group Table by editing the dicTableContextGroup.xml file that is found in the LEADTOOLS Sample Images folder. The dicTableContextGroup.xml file is a human-readable XML file that lists all of the DICOM context groups currently defined in the DICOM Specification. You can edit this with any text editor (i.e. notepad) to add or remove DICOM context groups. Then call LoadXml and pass the full path of the dicTableContextGroup.xml file. Note that calling LoadXml will first remove all context groups that are already present in the table.

For more information, see the topic Working with DICOM Tables

This example loads the DICOM Context Group table from the dicTableContextGroup.xml file that is shipped with the toolkit.
