GetPage Method

Summary
Gets the image page with the specified sub-cell index.
Syntax
C#
VB
C++
public RasterImage GetPage( 
   int pageIndex 
) 
  
Public Function GetPage( _ 
   ByVal pageIndex As Integer _ 
) As RasterImage 
            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.
