In digital typography, fonts define particular styles to be used for the characters’ appearance. Most often, the fonts are utilized in the documents and the web pages to stylize the text. Each font is described in a file that contains information about characters’ size, weight, styles, as well as encoding. Since fonts are an important part of the various file formats, Aspose offers a dedicated API for dealing with the manipulation and rendering of popular font types including TrueType, CFF, OpenType, and Type1. In this article, you will learn how to load, save, and extract information from fonts using C# with Aspose.Font for .NET.

- Load the font from the file (using file’s path or byte array) using FontDefinition class.
- Access font’s information using CffFont, TtfFont, or Type1Font class.
- Save the file (if required).
Load and Save CFF Font
The following code sample shows how to load and save CFF fonts using C#.
Load and Save TrueType Font
