<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$xmp = new CkXmp();

// 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 CkXml
$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 != true) {
    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 != true) {
    print $xmp->lastErrorText() . "\n";
    exit;
}

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

$success = $xmp->SaveAppFile('screamOut.jpg');
if ($success != true) {
