Private Fonts

GemBox.Presentation enables you to specify the location where it should look for font files when saving a presentation to PDF, XPS or image file formats, printing a presentation, or converting it to XpsDocument or ImageSource instances as in the following example.

This feature is especially useful for ASP.NET applications working in Medium Trust environment. By specifying a location that is under your ASP.NET application's control, GemBox.Presentation can use file system operations to retrieve font data even in Medium Trust environment.

By default, if location is not specified, GemBox.Presentation will look for font files in default font directory for the operating system.

Font file: Almonte Snow.ttf.
