Some file formats support embedded metadata, the kind of textual
information you can alter using the Adobe Photoshop 'File Info...'
command.
If this hint property is set to true the file or data that you
supply to the graphic object will be scanned for IPTC-NAA metadata.
This means you can extract embedded copyright, caption and other
information from images.
The IPTC information can be obtained using the IPTC property
which contains a collection of IPTC elements.
Setting the value of this property to false can result in faster
operations.
