C++ program to count the number of pages in a PDF file
In this tutorial, We are going to learn how to count the number of pages in a PDF file using C++. We can do this using the PoDoFo library to parse the document. Parse here means breaking long data into small parts by following a certain set of instructions. Let’s know a bit about the PoDoFo library file.
What is PoDoFo?
PoDofo is a free C++ library used for PDF file format and includes classes to parse the PDF files. The tools needed to work with pdf files are already given in a package form where you will download the podofo.
PoDoFo is easy to use and its code is written in C++. Code can be compiled in Mac Os, Windows as well as Unix.
C++ Code: Count the number of pages in a pdf file
#include <iostream> #include <podofo/podofo.h> void printHelp() { fprintf(stdout,"Usage: \npageCounting Inputfile\n" ); } int main(int argc,char* argv[]) { if (argc < 1) { printHelp(); exit(EXIT_FAILURE); } PoDoFo::PdfError::EnableDebug(false); unsigned int sum = -1; try { for( int i = 0 ; i < argc ; ++i) { PoDoFo::PdfMemDocument document(argv[i]); //parse the file int pageCount = document.GetPageCount(); // number of pages in pdf. std::cout << argv[i] << " : " << pageCount << " pagesinpdf\n"; sum += pageCount; } fprintf(stdout,"Number of pages in pdf will be : %d\n",sum); } catch(PoDoFo::PdfError& e) { fprintf(stderr,"Error:An error occured \n",e.GetError()); e.PrintErrorMsg(); return e.GetError(); } exit(EXIT_SUCCESS); }
Output:
Number of pages in a pdf will be: 120
