How Do I

How do I use the exported functions in a C++ application (not using COM)?

Here is a code sample demonstrating how to use the exported DLL functions in C++:

#define SC_PDF 0 //Create a normal editable file using 1.6 standard.
#define SC_PDF_A 1 //Create a PDF/A-2B write protected file for archiving.
//scConverter.dll exported functions
typedef int ( *SC_SET_PDFSTANDARD)( long Format );
typedef int ( *SC_SET_PDFLARGEFORMAT)( long Enable );
typedef int ( *SC_SET_PDFLAYERS)( long Enable );
typedef int ( *SC_SET_TIFFSINGLESTRIP)( long Enable );
typedef int ( *SC_SET_IMPORTERPATH)( WCHAR *Path);
typedef int ( *SC_CONVERT_FILE)( WCHAR *pSerialNumber, WCHAR *pInputFile, WCHAR *pOutputFile,
WCHAR *pFormat, double dScale, long lBitsPerPixel, long lDPI );

int ConvertFile( WCHAR *InputFile, WCHAR *OutputFile, WCHAR Format, long BitsPerPixel, long DPI)
   int result;
   HINSTANCE hLib = LoadLibrary( _T("scConverter.dll") );
   if (!hLib) return -1;
   //Get function pointers
   SC_CONVERT_FILE ConvertFileFunc = (SC_CONVERT_FILE)GetProcAddress( hLib, "scConvertFile" );
   SC_SET_PDFSTANDARD SetPDFStandardFunc = (SC_SET_PDFSTANDARD)GetProcAddress( hLib, "scSetPDFWriteFormat" );
   SC_SET_PDFLARGEFORMAT SetPDFLargeFormatFunc = (SC_SET_PDFLARGEFORMAT)GetProcAddress( hLib, "scSetPDFLargeFormat" );
   SC_SET_PDFLAYERS SetPDFLayersFunc = (SC_SET_PDFLAYERS)GetProcAddress( hLib, "scSetPDFLayers" );
   SC_SET_TIFFSINGLESTRIP SetTIFFSingleStripFunc= (SC_SET_TIFFSINGLESTRIP)GetProcAddress( hLib, "scSetTIFFSingleStrip" );
   SC_SET_IMPORTERPATH SetImporterPathFunc = (SC_SET_IMPORTERPATH)GetProcAddress( hLib, "scImportersPath" );
   //Setup and do the conversion
   SetPDFStandardFunc( SC_PDF_A );
   SetPDFLayersFunc( 1 );
   SetTIFFSingleStripFunc( 1 );
   SetPDFLargeFormatFunc( 1 );
   //Replace first paremeter _T("") with your serial number
   result = ConvertFileFunc( _T(""), InputFile, OutputFile, Format, 1.0, BitsPerPixel, DPI );
   FreeLibrary( hLib );
   return result;
Sample usage of this function:
//create PDF
ConvertFile( _T("c:\\temp\\test.plt"), _T("c:\\temp\test.pdf"), _T("PDF"), 1.0, 0, 0 );
//create monochrome TIFF, 300 dots per inch
ConvertFile( _T("c:\\temp\\test.plt"), _T("c:\\temp\test.tif"), _T("TIFF"), 1.0, 1, 300 );
//create true color TIFF, 200 dots per inch
ConvertFile( _T("c:\\temp\\test.plt"), _T("c:\\temp\test.tif"), _T("TIFF"), 1.0, 24, 200 );

How do I use the COM interface without using MFC or ATL in a C++ application?

Below you will find a code sample on how to create an instance of the component and then use it (no MFC/ATL):
int ConvertFile( WCHAR *InputFile, WCHAR *OutputFile, WCHAR *pFormat, double Scale, long BitsPerPixel, long DPI )
int nRetCode = 0;
if (SUCCEEDED(::CoInitialize(nullptr)))
   IConverter *pIConverter = nullptr;
   HRESULT hr = CoCreateInstance(CLSID_Converter, NULL, CLSCTX_ALL, IID_IConverter, (void **) &pIConverter);
   if (pIConverter)
      pIConverter->raw_SetSerialNumber( _T("") ); //Use your serial number here
      pIConverter->put_PDFWriteFormat(0); //Editable PDF 1.6, set to 1 for PDF/A
      pIConverter->put_PDFLayers(1); //Enable PDF layers
      pIConverter->put_PDFWriteFormat(1); //Enable large format PDF - allows maximum 60x60 meter extents
      pIConverter->put_TIFFSingleStrip(1); //Create single strip TIFF files (usually gives smaller file size).
      hr = pIConverter->raw_Convert( InputFile, //input filename,
         OutputFile, //output filename,
         Format, //format e.g.: PDF, TIFF, DWF etc,
         Scale, //Scaling
         BitsPerPixel, //Bits per pixel, e.g.: 1 = monochrome, 24 = true color
         DPI ); //Dots per inch (resolution), e.g. 200, 300, 600 etc.
      if (hr != S_OK )
         //Conversion failed - get error code
         long errorcode = 0;
         nRetCode = errorcode;
      pIConverter->Release(); //Release pointer to interface now
      pIConverter = nullptr;
      nRetCode = (int)hr; //scConverter.dll is not installed on this computer, or other COM problem, return hr
   return nRetCode;
