Wrapper for QPDF

This package can be used to merge (some pages of) PDF files into one PDF using the QPDF library.

Installation

composer require webstack/qpdf

Code examples

Combine two PDF files into one

<?phpuseWebstack\QPDF\QPDF;
require('vendor/autoload.php');
QPDF::createInstance()
->addFile('input-1.pdf')
->addFile('input-2.pdf')
->write('output.pdf');

Combine two PDF files into, specifying which pages to use

<?phpuseWebstack\QPDF\QPDF;
require('vendor/autoload.php');
QPDF::createInstance()
->addPages('input-1.pdf', '1-3')
->addPages('input-2.pdf', '4,5')
->write('output.pdf');

Returns the output instead of writing it to a file

<?phpuseWebstack\QPDF\QPDF;
require('vendor/autoload.php');
QPDF::createInstance()
->addFile('input-1.pdf')
->addFile('input-2.pdf')
->output();

Returns the number of pages in a file

<?phpuseWebstack\QPDF\QPDF;
require('vendor/autoload.php');
QPDF::createInstance()->getNumberOfPages('input-1.pdf');

vendor/bin/phpunit --bootstrap vendor/autoload.php tests

QPDF is a command-line program that does structural, content-preserving transformations on PDF files. It could have been called something like pdf-to-pdf. It also provides many useful capabilities to developers of PDF-producing software or for people who just want to look at the innards of a PDF file to learn more about how they work.
