GetPage Method

Example 





A zero-based index of the sub-cell to retrieve its frame.
Gets the image page with the specified sub-cell index.
Syntax
public RasterImage GetPage( 
   int pageIndex
)
'Declaration
 
Public Function GetPage( _
   ByVal pageIndex As Integer _
) As RasterImage
'Usage
 
Dim instance As MedicalViewerCell
Dim pageIndex As Integer
Dim value As RasterImage
 
value = instance.GetPage(pageIndex)
public RasterImage GetPage( 
   int pageIndex
)
 function Leadtools.MedicalViewer.MedicalViewerCell.GetPage( 
   pageIndex 
)
public:
RasterImage^ GetPage( 
   int pageIndex
) 

Parameters

pageIndex
A zero-based index of the sub-cell to retrieve its frame.

Return Value

Leadtools.RasterImage that represents the image assigned to the specified sub-cell index.
Remarks
This is only used with the MPR cell, or derivative cell.

This is useful, when the image is not generated, but the user wants it in anyway.
