Loads the specified RTF file as a Windows Enhanced Metafile.

Public Function LoadMetafile( _
ByVal fileName As String, _
ByVal pageNumber As Integer _
) As IntPtr
public:
IntPtr LoadMetafile(
String^ fileName,
int pageNumber
)
fileName
The source RTF file.
pageNumber
The 1-based page number to load.
The Windows Enhanced Metafile this method creates.
This method uses the following members of the current CodecsRasterizeDocumentLoadOptions set in RasterCodecs.Options.RasterizeDocument.Load to determine the page size, resolution and margins:
Also, it uses the following members of the current CodecsRtfLoadOptions set in RasterCodecs.Options.Rtf.Load to determine the back color to use:
So you must set these options according to your application needs before calling this method. The number of pages inside the RTF file will depend on the Rasterize Document options.
You must destroy the Windows Enhanced Metafile (EMF) handle this method creates manually using the DeleteEnhMetaFile Windows API.
