Add XMP MetaData to JPG or TIFF

See more XMP Examples

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

require 'chilkat'

success = false

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

xmp = Chilkat::CkXmp.new()

# 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
end

# 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
end

success = xmp.Append(xml)
if (success != true)
    print xmp.lastErrorText() + "\n";
    exit
end

success = xmp.SaveAppFile("screamOut.jpg")
if (success != true)
    print xmp.lastErrorText() + "\n";
    exit
end
