GtkMathView

GtkMathView is a neat C++ rendering engine designed for MathML documents. It gives you an interactive way to browse and edit MathML markup, making it super handy for anyone dealing with math content!

How GtkMathView Works

This software reads MathML documents using a frontend that helps navigate through the document (or parts of it) and sets up GtkMathView's internal data structures for rendering. Pretty cool, right?

Supported Frontends

• libxml2 frontend: This one represents the MathML document as a tree and uses the libxml2 tree API to navigate.


• libxml2 reader frontend: Instead of loading the whole document at once, this one navigates with the libxml2 reader API. It's perfect for batch rendering!


• GMetaDOM frontend: This frontend also uses a tree representation but navigates with GMetaDOM's DOM API, which is a wrapper around libxml2.


• Custom frontend: If you have an application-specific format, this option lets you navigate with your own callback functions.

The Rendering Process

The backend of GtkMathView is where all the magic happens. It provides an abstraction over platform-specific features like available fonts and drawing tools.

Available Backends

• GTK+ backend: This lets you render MathML documents in GTK+ applications using Pango.


• GTK+ widget backend: Wraps GtkMathView in a GTK+ widget so it can be embedded directly in GTK+ apps.


• SVG backend: Renders MathML into SVG format.


• AbiWord backend: Allows embedding MathML documents into AbiWord through the AbiMathView plugin.

System Requirements

• - GCC ≥ 3.4: (some older versions may cause issues).


• - GLib ≥ 2.2.1


• - GTK+ ≥ 2.2.1 (needed up to version 0.6.5; optional from version 0.7.0).


• - GMetaDOM ≥ 0.1.8 (required for older versions).


• - miniDOM support has been dropped since gtkmathview ≥ 0.4.x.


• - libxml ≥ 2.6.7 (required for earlier versions).


• - t1lib ≥ 5 if using Type 1 fonts and anti-aliasing (RPMs available at Didier's page).

What's New

In this latest release:

• Fixed bugs related to rendering tables and scripts in MathML.


• Added support for two new fonts: MSAM and MSBM from AMS.
