Rotation
This demo shows the rotation behavior of stamp objects. The rotation is done so that the stamp appearance is completely visible throughout.
PHP
<?php
// load and register the autoload function
require_once __DIR__ . '/../../../../../bootstrap.php';
$rotationOptions = require 'options.php';
$value = displaySelect('Position & Rotation:', $rotationOptions);
$data = $rotationOptions[$value];
$writer = new \SetaPDF_Core_Writer_Http('positioning-and-translate.pdf', true);
$document = new \SetaPDF_Core_Document($writer);
// let's add 2 pages for demonstration purpose
$pages = $document->getCatalog()->getPages();
$pages->create(\SetaPDF_Core_PageFormats::A4, \SetaPDF_Core_PageFormats::ORIENTATION_PORTRAIT);
$pages->create(\SetaPDF_Core_PageFormats::A4, \SetaPDF_Core_PageFormats::ORIENTATION_LANDSCAPE);
// create a stamper instance
$stamper = new \SetaPDF_Stamper($document);
// create a font instance which is needed for the text stamp instance
$font = new \SetaPDF_Core_Font_TrueType_Subset(
$document,
$assetsDirectory . '/fonts/DejaVu/ttf/DejaVuSans.ttf'
);
// create a stamp instance
$stamp = new \SetaPDF_Stamper_Stamp_Text($font, 12);
$stamp->setBackgroundColor([0.5, 1, 1]);
$stamp->setBorderWidth(1);
$stamp->setPadding(2);
$stamp->setWidth(180);
$stamp->setAlign(\SetaPDF_Core_Text::ALIGN_CENTER);
$stamp->setText('A simple example text to demonstrate rotation.');
// add the stamp object on all pages on the given position
$stamper->addStamp(
$stamp,
[
'position' => $data['position'],
'rotation' => $data['rotation']
]
);
// execute the stamp process
$stamper->stamp();
// save and finish the document instance
$document->save()->finish();
