Here you will find information on the Math Component, which is part of the Sandcastle Assist custom build components for the
, a documentation compiler for managed class libraries.
: Reference and Conceptual Documents
The component allows you to type mathematical formula and equations into both reference and conceptual documents
and have this transformed into an image and inserted into the final output.
- While working on a company product's documentation recently, we needed math equations embedded into the documents, and bought a commercial tool for this. The quality of the output was not very impressive, and the whole process was time consuming.
- The conceptual help MAML supports a tag
<math/>, which by the documentation is used for math equations so all that was needed was the tool to transform that into images. With a background in TeX/LaTeX, we started looking for a LaTeX-based solution and found it easy. This is what we are
sharing with the Sandcastle community.
- LaTeX, the undisputed leader in math equations, is fully supported,
- MathML, the support is planned but not currently available.
: If you are not comfortable with LaTeX format, you can use the free WYSIWYG Tool,
or the commercial version MathType by the same company. Both produce a LaTeX output you insert into your document, you can be assured that the output will have a better quality that the MathType
The implementation is flexible, and could be easily extended to support any format. The conversion is done in
class shown in the diagram below:
Requirements and Installations
- MathML: This is currently not implemented and there is no requirement yet.
- LaTeX: The requirements and installations depends your choice of rendering engine:
- Using MimeTeX: This is a simple TeX implementation, which parses a LaTeX math expression and immediately emits the corresponding gif image, rather than the usual TeX dvi.
- It requires no installation or configurations, and it comes with the Sandcastle Assist package.
- It is very small (548 KB) and fast
- The quality of the output is poor, but not be good for most documentation requirements.
- Using MikTeX: This is the most is an up-to-date TeX implementation for the Windows operating system, and produces full dvi.
- It requires installation and configuration, but the math component is fully functional with the
- It is big 77.79 MB, and may be slower.
- The quality is very high and offers many customizations.
: If you have the disk space for the 77.79 MB, we recommend you install the MikTeX for a full LaTeX experience.
The following features are currently support by the math build component
- In-line mathematical equations.
- Displayed mathematical equations.
- Use of two different rendering engines depending on user's quality requirement and machine specifications.
- Automatic equation numbering, with customization of format and style.
- Customization of the math environment styles.
- No change to the current limited environment defined by the conceptual <math/> tag.
- Easy and highly flexible.
As stated above, we did not change the current <math/> tag or added new attributes, since that will break the current MAML schema.
We, however, took the advantage of lack of the <math/> tag in the references documents to introduce more flexible extensions.

Configurations and Options
TODO: Under Construction
Provide the configurations and options
Here are some screenshots of the output from the math custom build component in a conceptual documentation. It demonstrates the following
- The quality output of the MikTeX.
- The use of 12pts font size instead of the default 10pts.
- The in-line and displayed equations.
- Use of custom equation number format, which includes "Eqn." text and page number.
