Syntax

Visual Basic (Declaration)
Public Function ExportPage( _ ByVal pageIndex As Integer _ ) As RasterImage

Visual Basic (Usage)	Copy Code
`Dim instance As RasterDocumentEngine Dim pageIndex As Integer Dim value As RasterImage value = instance.ExportPage(pageIndex)`

C#
public RasterImage ExportPage( int pageIndex )

Managed Extensions for C++
public: RasterImage ExportPage( int pageIndex )

C++/CLI
public: RasterImage ExportPage( int pageIndex )

Parameters

pageIndex: Index of the page to be updated. This is a zero-based index.

Return Value

If successful, returns the exported page as an RasterImage object.
