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

$xmp = New-Object 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 = $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 -ne $true) {
    $($xml.LastErrorText)
    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 -ne $true) {
    $($xmp.LastErrorText)
    exit
}

$success = $xmp.Append($xml)
if ($success -ne $true) {
    $($xmp.LastErrorText)
    exit
}

$success = $xmp.SaveAppFile("screamOut.jpg")
if ($success -ne $true) {
    $($xmp.LastErrorText)
    exit
