L_LTFIL_API L_INT EXT_FUNCTION L_GetEmfHandleFromRtf (pRtfFileName, nPageNumber, pRtfOptions, pRasterizeDocOptions, hEmfHandle)

L_TCHAR * pRtfFileName;	file name
L_INT nPageNumber;	page number
pFILERTFOPTIONS pRtfOptions;	pointer to a structure
pRASTERIZEDOCOPTIONS pRasterizeDocOptions;	pointer to a structure
HENHMETAFILE * hEmfHandle;	pointer to an EMF handle

Gets an EMF handle from a specific page in RTF file.

Parameter	Description
pRtfFileName	Character string that contains the name of the source RTF file.
nPageNumber	Number of the RTF page to get its EMF handle. The page number is 1-based. Therefore, the first page is page 1, the second page is page 2, etc.
pRtfOptions	Pointer to a structure that contains the options to be used when loading RTF file. The following options will be used: RTFFILEOPTIONS.crBackColor.
pRasterizeDocOptions	Pointer to a structure that contains the options to be used when rasterizing document files. The following options will be used: RASTERIZEDOCOPTIONS.uXResolution, RASTERIZEDOCOPTIONS.uYResolution, RASTERIZEDOCOPTIONS.dPageHeight, RASTERIZEDOCOPTIONS.dPageWidth, RASTERIZEDOCOPTIONS.dLeftMargin, RASTERIZEDOCOPTIONS.dTopMargin, RASTERIZEDOCOPTIONS.dRightMargin and RASTERIZEDOCOPTIONS.dBottomMargin
hEmfHandle	Address of an Enhanced Metafile (EMF) handle that will be updated with the obtained EMF.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
