Fonts
GemBox.Presentation needs access to fonts used in a presentation when printing or saving to PDF, XPS, and image formats. By default, it will check these font locations on supported operating systems:
- Windows: C:\Windows\Fonts\
- Linux: /usr/share/fonts/, /usr/local/share/fonts/, and ~/.local/share/fonts/
- macOS: /System/Library/Fonts/, /Library/Fonts/, and ~/Library/Fonts/
If a specific font is not located at the default location, you need to use the The following example shows how you can specify the location of a private or custom font (Almonte Snow.ttf) when saving a presentation to PDF. GemBox.Presentation supports retrieving fonts stored as resources inside the local or referenced assembly by specifying the When you add fonts as resources to your application, make sure you're setting the Build Action as an Embedded resource. Or if your application is targeting .NET Framework and thus uses WPF, set it as Resource instead. The following image shows a structure of an example solution with font files added as embedded resources, and the following table lists base resource locations you need to specify to use those fonts.FontSettings static class to specify the location of that font. This is especially needed in environments with no fonts installed, like Docker.Custom fonts
