LoadRegion Method (MedicalViewerCell)

Loads regions from a file.

Syntax

C#
Visual Basic
Objective-C
Java
C++

public void LoadRegion( 
   string fileName
)

'Declaration
 
Public Sub LoadRegion( _
   ByVal fileName As String _
)

'Usage
 
Dim instance As MedicalViewerCell
Dim fileName As String
 
instance.LoadRegion(fileName)

public:
void LoadRegion( 
   String^ fileName
)

Parameters

fileName: A string that contains the path to the file that contains the region(s) to load.

Remarks

This method will load the region from the file created by the MedicalViewerMultiCell.SaveRegion method.
If the file contains more than one region, the control will load the new region in the next sub-cell, then it will move to the next cell and load the rest of the regions.
For more information, refer to Working With Regions.
