If metadata does not contain XMP properties belonging to the TIFF scheme, the method returns null.

If the metadata does not have TIFF XMP properties, and you need to add such properties, create a new instance of the com.accusoft.imagegear.formats.xmp.tiff.ImGearTIFFXMPMetadata class, assign it using corresponding setter, and then add XMP properties using corresponding properties of the com.accusoft.imagegear.formats.xmp.tiff.ImGearTIFFXMPMetadata class.

If you need to remove TIFF XMP schema properties from the metadata, set this value to null.
