If possible, then use the dynapdf.dll instead. This library requires no additional dependencies to

enable 64 bit file support.

If you want to use DynaPDF with a C++ project, add the line "using namespace DynaPDF;" after

including the header file dynapdf.h.

The usage in C is essentially the same as in C++, with the exception that the namespace

DynaPDF must not be declared.

A PDF instance can be used to create an arbitrary count of PDF files. All used resources are

automatically freed when the PDF file is closed (except when the PDF file was created in

memory). To improve processing speed, use one instance as long as possible.

Most examples are written in C or C++ which can directly be used with a Embarcadero or

Microsoft Compiler.

Example (C++):

// Include the DynaPDF header file (change the path if necessary)

#include "dynapdf.h"

// All data types and functions are declared in the namespace DynaPDF.

using namespace DynaPDF;

// First, we declare an error callback function that is called by

// DynaPDF if an error occurred.

SI32 PDF_CALL PDFError(const void* Data, SI32 ErrCode, const char*

ErrMessage, SI32 ErrType)

{

printf("%s\n", ErrMessage);

return 0; // Any other return value break processing

}

// Place a button on the form and double click on it. Add the

following

// code to the function.

int main(int argc, char* argv[])

{

void* pdf = pdfNewPDF(); // Create a new PDF instance

if (!pdf) return 2; // Out of memory?

// Set the error callback first

pdfSetOnErrorProc(pdf, NULL, PDFError);

pdfCreateNewPDF(pdf, "c:/myfirst.pdf");

pdfSetPageCoords(pdf, pcTopDown); // We use top-down coordinates

pdfAppend(pdf);

pdfSetFont(pdf, "Arial", fsItalic, 40.0, true, cp1252);

pdfWriteFText(pdf, taCenter, "My first C++ output!");

pdfEndPage(pdf);

pdfCloseFile(pdf); // Close the file and free all used resources

pdfDeletePDF(pdf); // Do not forget to delete the PDF instance

}
