## Detailed Description

In PDF document, font is used for drawing text in PDF page.
This class represents font used in Foxit PDF SDK. This class offers different constructor for user to construct a new font object, by specified parameters, by standard font ID, or from a font file path. A font object can also be retrieved directly from other object (such as free text annotation, a text graphics object, etc) in a PDF document. This class also offers some functions to get some basic information from a font.
