PHP
<?php // load and register the autoload function require_once __DIR__ . '/../../../../../bootstrap.php'; $writer = new \SetaPDF_Core_Writer_Http('visible-signature.pdf', true); $document = \SetaPDF_Core_Document::loadByFilename( $assetsDirectory . '/pdfs/camtown/Laboratory-Report.pdf', $writer ); // create a signer instance $signer = new \SetaPDF_Signer($document); // add a visible signature field $field = $signer->addSignatureField( \SetaPDF_Signer_SignatureField::DEFAULT_FIELD_NAME, 1, \SetaPDF_Signer_SignatureField::POSITION_RIGHT_TOP, ['x' => -160, 'y' => -100], 180, 60 ); // and define that you want to use this field $signer->setSignatureFieldName($field->getQualifiedName()); $certificatePath = $assetsDirectory . '/certificates/setapdf-no-pw.pem'; // now create a signature module $module = new \SetaPDF_Signer_Signature_Module_Pades(); // pass the path to the certificate $module->setCertificate('file://' . $certificatePath); // set the path to the private key (in this demo the key is also saved in the certificate file) $module->setPrivateKey('file://' . $certificatePath, ''); // now create the appearance module and pass the signature module along $appearance = new \SetaPDF_Signer_Signature_Appearance_Dynamic($module); // let's create a font instance to not use standard fonts (not embedded) $font = new \SetaPDF_Core_Font_Type0_Subset( $document, $assetsDirectory . '/fonts/DejaVu/ttf/DejaVuSans.ttf' ); // and pass it to the appearance module $appearance->setFont($font); // pass the appearance module to the signer instance $signer->setAppearance($appearance); // sign the document $signer->sign($module);
