Delete Pages
This demo shows you how to delete all but the first page of a PDF document and save the complete document.
ONLY USE THIS LOGIC IF YOU KNOW THE PDF DOCUMENT AND THE DELETED PAGES ARE NOT REFERENCED INTERNALLY
PHP
<?php
// load and register the autoload function
require_once __DIR__ . '/../../../../../bootstrap.php';
$files = [
$assetsDirectory . '/pdfs/Brand-Guide.pdf',
$assetsDirectory . '/pdfs/camtown/Terms-and-Conditions.pdf',
$assetsDirectory . '/pdfs/etown/Laboratory-Report.pdf'
];
$path = displayFiles($files);
// create a reader
$reader = new \SetaPDF_Core_Reader_File($path);
// create a writer
$writer = new \SetaPDF_Core_Writer_Http('delete-pages.pdf', true);
// create a document
$document = \SetaPDF_Core_Document::load($reader, $writer);
// get the pages helper
$pages = $document->getCatalog()->getPages();
// or
// $pages = $document->getPages();
// delete all but the first page
while ($pages->count() > 1) {
$pages->deletePage($pages->count());
}
// save the complete document
$document->save(false)->finish();
