Example #1 Embedding IPTC data into a JPEG <?php // iptc_make_tag() function by Thies C. Arntzen function iptc_make_tag($rec, $data, $value) { $length = strlen($value); $retval = chr(0x1C) . chr($rec) . chr($data); if($length < 0x8000) { $retval .= chr($length >> 8) . chr($length & 0xFF); } else { $retval .= chr(0x80) . chr(0x04) . chr(($length >> 24) & 0xFF) . chr(($length >> 16) & 0xFF) . chr(($length >> 8) & 0xFF) . chr($length & 0xFF); } return $retval . $value; } // Path to jpeg file $path = './phplogo.jpg'; // We need to check if theres any IPTC data in the jpeg image. If there is then // bail out because we cannot embed any image that already has some IPTC data! $image = getimagesize($path, $info); if(isset($info['APP13'])) { die('Error: IPTC data found in source image, cannot continue'); } // Set the IPTC tags $iptc = array( '2#120' => 'Test image', '2#116' => 'Copyright 2008-2009, The PHP Group' ); // Convert the IPTC tags into binary code $data = ''; foreach($iptc as $tag => $string) { $tag = substr($tag, 2); $data .= iptc_make_tag(2, $tag, $string); } // Embed the IPTC data $content = iptcembed($data, $path); // Write the new image data out to the file. $fp = fopen($path, "wb"); fwrite($fp, $content); fclose($fp); ?>
