Private Fonts

GemBox.Pdf enables you to use either system or private fonts when writing text.

Private fonts can be located either in a custom directory or embedded in an assembly. Using private fonts is required in restricted environments, such as ASP.NET applications working in Medium Level Trust where accessing the default font directory for the operating system is not allowed.

Additionally, the PdfFonts class enables you to browse all standard, system, and private font families and font faces.

The following example shows how to write text using private fonts (Almonte Snow.ttf and almonte woodgrain.ttf) located in the same directory as the application.
