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 |
