Comments

Loading a PDF as a raster image in LEADTOOLS is accomplished by two DLLs:

  1. LTPDF?.dll is the DLL for PDF format. Use this DLL as any other file filter
    in LEADTOOLS, such as LFBMP?.dll for BMP support and LFTIF?.dll for TIF support.

  2. LTPDFENGINE?.DLL is the engine runtime DLL. It contains many resources such as tables
    and fonts required to render a PDF image. This DLL is not referenced in a direct
    way by the file filter. Instead it is loaded dynamically and out of a process. You
    must ensure that this DLL is present on the machine to support loading PDF files.
    By default, it is required to have this DLL in the same directory where the
    file filter is located. However, to share many instances of LTPDFENGINE?.dll between
    many applications, use the L_SetPDFInitDir method.

If you call this function with an empty string (length = 0), then the LTPDF?.dll
will look for LTPDFENGINE.dll in the same physical directory it currently resides in.

Example

This example will show how to get the path of PDF initialization directories

L_INT SetPDFInitDirExample(L_VOID) 
{ 
   L_INT nRet; 
   L_TCHAR *pszInitDir=NULL; 
   pszInitDir = (L_TCHAR*)malloc(MAX_PATH*sizeof(L_TCHAR)); 
   nRet = L_GetPDFInitDir(pszInitDir, MAX_PATH); 
   if(nRet != SUCCESS) 
      return nRet; 
   nRet = L_SetPDFInitDir(pszInitDir); 
   free(pszInitDir); 
   return nRet; 
}
