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

xmp = chilkat2.Xmp()

# Load a JPG or TIF image file.
success = xmp.LoadAppFile("qa_data/xmp/AJ_123642_1511.tif")
if (success != True):
    print(xmp.LastErrorText)
    sys.exit()

print("Num embedded XMP docs: " + str(xmp.NumEmbedded))

# This example assumes that XMP metadata is already present in the image file.
if (xmp.NumEmbedded == 0):
    print("No XMP metadata already exists..")
    sys.exit()

# Get the XMP metadata.

# xml is a CkXml
xml = xmp.GetEmbedded(0)

# Show the XML:
print(xml.GetXml())

# Update (overwrite) a string property.
xmp.AddSimpleStr(xml,"NumberofTimes","123")
