Overview - Document Composer

Introduction

The DocumentComposer class, which is available in both Java and Windows-only versions (including 32- and 64-bit versions), is used to transform MathML embedded in documents into additional information (e.g., spoken speech for the equation in the Windows Composer) or replace it with images. It can produce EPS (Windows only), GIF, and PNG image types.

Programming Model

The DocumentComposer class is based on a state model. When a DocumentComposer object is instantiated, an internal collection of parameters is initialized. These parameters control licensing, input, output, rendering, font management, persistence and other functions. These internal parameters are modifiable by setter methods, which allow you to change the value of the parameters before an image is generated. Refer to the Java Document Composer API or Windows Document Composer API for the DocumentComposer class to see what setter methods are available.

Processing a Document

Once all of the parameters have been set, a call to ProcessDocument() will transform the MathML and output a new document in the format and location defined by the parameters.

Configuring Fonts

You can choose which fonts are used when creating equation images. To do this, you need to create font configuration files. See Windows Font Configuration or Java Rendering Engine for more information.
