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

loXmp = createobject("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.  
loXml = loXmp.NewXmp()

// Add some properties...
llSuccess = loXmp.AddSimpleStr(loXml,"Iptc4xmpCore:Chilkat","Blah blah")
// If you wish to view the XML, save it to a file and review it
// with a text editor:
llSuccess = loXml.SaveXml("newXmp.xml")
if (llSuccess <> .T.) then
    ? loXml.LastErrorText
    release loXmp
    return
endif

// To add the XMP to the JPG (or TIFF), simply load the JPG,
// append the XMP, and save:
llSuccess = loXmp.LoadAppFile("scream.jpg")
if (llSuccess <> .T.) then
    ? loXmp.LastErrorText
    release loXmp
    return
endif

llSuccess = loXmp.Append(loXml)
if (llSuccess <> .T.) then
    ? loXmp.LastErrorText
    release loXmp
    return
endif

llSuccess = loXmp.SaveAppFile("screamOut.jpg")
if (llSuccess <> .T.) then
    ? loXmp.LastErrorText
    release loXmp
