class PDFHyperlink:
The PDFHyperlink structure contains information of a single PDF hyperlink. To read hyperlinks from a PDF file, use the PDFDocument.ParsePages method with the PDFParsePagesOptions.Hyperlinks specified in the options parameter passed to the method. The PDFDocumentPage.Hyperlinks collections will be populated with the hyperlinks of the page.
A hyper link is not a visible object on the page, rather, it is parsed from the text of the object. So for every hyperlink on a page, there will also exist the actual PDFObject of type PDFObjectType.Text that forms the hyperlink text. The PDFDocumentPage.Hyperlinks collection gives you a quick access to all the hyperlinks of a page in one convenient location.
The PDFHyperlink structure contains these properties:
Bounds: This is the location and size on the hyperlink of the link hot spot. An external viewer may choose to change the mouse cursor shape to a "Hand" when the user hovers over this link and proceed to perform the action of the link when the user clicks link.
Hyperlink: The hyperlink string read from the PDF document. An external viewer may choose to start an external application such as a web browser when this link is clicked.
TextProperties: The hyperlink text properties such as font information and color.
