This is an extension step; to use it, your pipeline must include its declaration. For example, by including the extension library with an import at the top of your pipeline:
<p:import href="https://xmlcalabash.com/ext/library/diagramming.xpl"/>

Description

The cx:mathml-to-svg step uses JEuclid to convert MathML to SVG.

ⓘ
Note

The actual implementation used is version 3.1.14 of a modern fork of JEuclid that supports recent versions of Java and the underlying Batik libraries.

Example

The equation rendered in Figure 1, “Example MathML converted to SVG” is one of the more interesting (looking) examples from the Mozilla MathML torture test.

Figure 1. Example MathML converted to SVG

Correct rendering of Figure 1, “Example MathML converted to SVG” relies on support for SVG in your user agent. If your user agent also supports MathML, it can render the equation directly, as (possibly) shown in Figure 2, “Example MathML”.

det ( A ) = ∑ σ ∊ S n ϵ ( σ ) ∏ i = 1 n a i , σ i

Dependencies

This step is included in the XML Calabash application. If you are getting XML Calabash from Maven, you will also need to include the extension dependency:

  • com.xmlcalabash:diagramming:3.0.0-alpha23

The following third-party dependencies will also be included transitively:

  • net.sourceforge.plantuml:plantuml:1.2025.0
  • de.rototor.jeuclid:jeuclid-core:3.1.14
  • ditaa0.9.jar, included in the XML Calabash extension because it’s not available through Maven.
