manipulate fonts in java

Fonts play an important role in the presentation of the text within the documents and web pages. Various font families are available that allow you to use fancy characters in order to make your text appealing. Since Aspose deals with file format automation, we have launched a dedicated font manipulation API to work with font file formats. In this article, you will get familiar with our Java Font API and learn how to work with CFF, TrueType, OpenType, and Type1 fonts from within your Java applications.

Java Font Manipulation API

Aspose.Font for Java is the font manipulation API that allows you to load, save, and manipulate popular fonts including CFF, TrueType, Type1, EOT, and OpenType. In addition, the API supports retrieving font metrics as well as rendering the text using the supported font types. You can download the API or install it within your Maven-based applications using the following configurations.
