Gets the properties (or metadata) of the current document.
The metadata of the document depends on the format. For PDF and XPS files, the metadata is loaded directly from the file and you will get information such as Author, Subject and Keywords. For raster files such as JPEG, EXIF and TIFF, the toolkit will try to load any comments stored in the file such as Author and Copyright.
For an example, refer to DocumentReader.
