Smart Canvasses

The Microsoft Math graphing calculator folks have created a Word 2007 add-in that lets you simplify, solve, calculate, and graph your equations in 2-D or 3-D. With it installed, your technical paper becomes alive. For example, your paper may have graphs of the formulae, but a reader wants graphs for different sets of parameters. She…

STIX Beta Fonts

The STIX folks (Scientific and Technical Information eXchange) folks have a beta version of their math font. There are more math characters in the STIX fonts than in Cambria Math. The primary typeface is Times Roman. This post describes how you can examine the fonts and gives some reasons why they aren’t quite ready to…

Using RichEdit 6.0 for Math

A number of readers have asked how to use the RichEdit 6.0 shipped with Office 2007 to edit and display mathematical text. This post explains one way to do so. The code assumes that you already have an application that knows how to instantiate a RichEdit control with a window identified by hwndRE. The function…

Using Left/Right Arrow Keys in Mathematical Text

Paul Libbrecht commented that there’s more to selection in math text than discussed in my first post on this subject. As usual, Paul is right. That post explains how one or more characters and/or math objects are selected. In addition the topic of selection includes insertion-point behavior, which by definition selects no characters or objects….

Breaking Equations into Multiple Lines

Long equations often do not fit on a single line and ways are needed to break them up for display on multiple lines. Word 2007 offers two approaches: automatic and manual line breaking. A related feature is alignment of multiple equations, such as aligning the equal signs of a group of equations. This post describes…

Automatic arguments

The arguments of math display objects are either optional or essential. Examples of essential arguments are the numerator and denominator of a fraction. For a legitimate fraction, both are nonempty. Hence if either or both are empty, they should be represented by a dotted square box, which indicates that an essential argument is missing. Optional…

Math Selection

Selection of text in a math zone obeys some special rules concerning built-up math objects, such as fractions and integrals. First some background on how these objects are stored helps to clarify the rules. In memory, math objects start with a special 16-bit character and end with a different 16-bit character. In RichEdit, the start…

Getting Word 2007 Technical Files into Publisher Pipelines

Nature, Science and other publishers have robust ways of converting Word 2003 documents with embedded Equation Editor and MathType objects into the XML representation they use for publication. Notably MathType can export mathematical equations as MathML and this capability is part of the methodology. In principle a similar approach can be used with Word 2007…

Science and Nature have difficulties with Word 2007 mathematics

Science and Nature, two premier science publications, are having difficulties with Word 2007’s elegant new mathematics facility. Part of the reason is due to misunderstanding about Word’s MathML support, which hopefully this post will help to rectify. And part of it is that the new facility represents mathematical text in a way that Word itself…

Using Math Italic and Bold in Word 2007

Mathematical variables represented by Latin and lower-case Greek letters are usually displayed in italic. Vectors are often displayed in upright boldface. Word 2007 allows the user to control and change these choices with the italic and bold formatting buttons on the Home tab of the user-interface ribbon or with the italic and bold hot keys…
