Combining two PDF files in C++

Question

In C++ I'm generating a PDF report with libHaru. I'm looking for someway to append two pages from an existing PDF file to the end of my report. Is there any free way to do that?

Thanks.

Answer 1

You can use the Ghostscript utility pdf2ps to convert the PDF files to PostScript, append the PostScript files, and then convert them back to a PDF using ps2pdf.

Answer 2

Try PoDoFo

http://podofo.sourceforge.net/

You should be able to open both of the PDFs as PDFMemDocuments using PDFMemDocument.Load( filename ). Then, aquire references to the two pages you want to copy and add to the end of the document using InsertPages, or optionally, remove all but the last two pages of the source document, then call PDFDocument.Append and pass the culled document. Hard to say which would be faster or more stable.

Hope that helps, Troy
