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

Dim xmp As New Chilkat.Xmp

Dim xml As Chilkat.Xml

// 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 <> True) Then
    System.DebugLog(xml.LastErrorText)
    Return
End If

// 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) Then
    System.DebugLog(xmp.LastErrorText)
