Demonstrates how to add XMP metadata to a JPG or TIFF image that doesn't already have XMP metadata. B4X

Dim success As Boolean = False

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

Dim xmp As ChilkatXmp
xmp.Initialize

Dim xml As ChilkatXml

'  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
    Log(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
    Log(xmp.LastErrorText)
    Return
End If

success = xmp.Append(xml)
If success <> True Then
    Log(xmp.LastErrorText)
    Return
End If

success = xmp.SaveAppFile("screamOut.jpg")
If success <> True Then
    Log(xmp.LastErrorText)
    Return
End If
