(PHP ActiveX) Add XMP MetaData to JPG or TIFF

Demonstrates how to add XMP metadata to a JPG or TIFF image that doesn't already have XMP metadata.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xmp')
$xmp = new COM("Chilkat.Xmp");

// The first step is to create a new XMP document, which is nothing
// more than XML.  The NewXmp method returns an XML document with
// the standard XMP boilerplate.  
// xml is a Chilkat.Xml
$xml = $xmp->NewXmp();

// Add some properties...
$success = $xmp->AddSimpleStr($xml,'Iptc4xmpCore:Chilkat','Blah blah');
// If you wish to view the XML, save it to a file and review it
// with a text editor:
$success = $xml->SaveXml('newXmp.xml');
if ($success != 1) {
    print $xml->LastErrorText . "\n";
    exit;
}

// To add the XMP to the JPG (or TIFF), simply load the JPG,
// append the XMP, and save:
$success = $xmp->LoadAppFile('scream.jpg');
if ($success != 1) {
    print $xmp->LastErrorText . "\n";
    exit;
}

$success = $xmp->Append($xml);
if ($success != 1) {
    print $xmp->LastErrorText . "\n";
    exit;
}

$success = $xmp->SaveAppFile('screamOut.jpg');
if ($success != 1) {
    print $xmp->LastErrorText . "\n";
    exit;
}
