The purpose of these notes is to attempt to describe MathType 5's new features in a manner appropriate for a member of the press intending to write a review of the product. We encourage you to also browse the rest of our web site to get an even more complete picture of Design Science and its products.

MathType Background

MathType 5.0 for Macintosh is a new version of Design Science’s MathType mathematical equation editing software for Mac OS 9.x, and Mac OS X 10.1 and newer. This release brings the Macintosh version up to the same level of functionality as the Windows version. MathType's users include math and science teachers preparing tests and other classroom materials, college faculty preparing tests, classroom materials, research papers, web pages, and presentations, and scientists and engineers in industry and academia.

MathType 5.0 is an OLE 2 object server, allowing equation objects to be placed in documents created by any application that supports OLE. On the Macintosh platform this includes all Microsoft Office applications. MathType 5.0 also supports EGO (Edit Graphic Object), a similar technology supported by AppleWorks, DeltaGraph and other programs.

It also can produce equations as Macintosh PICT, Encapsulated PostScript (EPS), and Graphics Interchange Format (GIF) files. Its equations can be converted to TeX, LaTeX, AMS-TeX, AMS-LaTeX, as well as MathML 1.0 and 2.0. MathML is the XML-based mathematical description language made an official Recommendation in April, 1998 by the World Wide Web Consortium (W3C, see http://www.w3.org/Math/ for more information).

MathType is the professional version of Equation Editor, which Design Science licenses to Microsoft for use in its Office, Word, PowerPoint, and Works packages, Apple for use in AppleWorks, as well as many other software companies. Equation Editor users and anyone else can download MathType and try it free for 30 days, and will get hundreds more mathematical characters and templates, the ability to save to various graphic file formats, the ability to save expressions on its toolbar for quicker equation creation and editing, greater control over formatting, TeX and MathML translation, web page creation, and more.

New Features

New Templates

MathType 5 includes many new templates, including:

horizontal brackets
integrals with directional loops
hats, arcs etc. over multiple characters
"cross-outs" (useful for showing cancellation of terms)
expanding arrows for chemical equilibrium equations
actuarial notation
boxes around expressions

Fonts

MathType 5 includes the Euclid font set containing hundreds of mathematical characters and is provided in both TrueType and PostScript formats. Euclid is Design Science's versions of TeX's Computer Modern typefaces which have established a somewhat standard look for technical documents. Users of Equation Editor, and previous versions of MathType, will discover many new mathematical symbols, including double-stroked "blackboard bold", bold Greek, and script alphabets.

Toolbar

MathType 5 has a more powerful and customizable toolbar than before. It allows access to MathType's built-in symbols and templates, as well as hundreds of user-defined expressions (see Expression Library below). Users can also choose from three user-interface sizes so that symbols are clearly visible in all combinations of screen size and vision constraints.

Expression Library

MathType's toolbar provides access to a customizable expression library that contains hundreds of mathematical symbols and templates from MathType's menus, as well as characters from any font, expressions or even entire equations. Parts of an equation, or a whole equation, can be dragged to the toolbar, and then re-used in any other equation with a single click. Users can add their own description for each expression, and also assign keyboard shortcuts. Expressions can also be opened into a separate equation window for editing. The toolbar contains tabbed bars for access to hundreds of expressions, and users can rename the tabs to suit their toolbar organization, e.g. "Statistics", "Geometry" etc.

Color

In MathType 5 all, or parts of an equation can be colored. This is useful for directing attention to specific parts of an equation for teaching purposes, or for creating equations to be used in PowerPoint or Keynote presentations. MathType also supports CMYK, RGB and spot color palettes for use in professional publishing applications.

Insert Symbol

This dialog offers quick access to all fonts on the user's computer. Characters can be viewed by font, and a powerful searching capability allows users to enter a description of a character (e.g. "infinity") and see all available versions of this character without knowing which font(s) contain the character. Characters can also be dragged to the toolbar for later use in equations.

Customizable Function Recognition

Previous versions supported recognition of a fixed set of functions such as "sin, "cos" etc., so that they will be assigned the appropriate font and style. MathType 5 allows users to customize this list.

Zoom to 800%

MathType 5 now supports zooming to 800% to allow very fine adjustment of equation elements.

MathML, LaTeX and TeX Translators

MathType 5's translation facility has been completely re-written, and is now based on user-editable text files containing translation rules for each output. MathType includes translators for MathML 2.0 and 1.0, as well as several flavors of LaTeX and TeX.

Customizable Keyboard Shortcuts

MathType 5 provides keyboard shortcuts for virtually every command, symbol and template. These shortcuts can be modified, and new shortcuts can be assigned to items added to the toolbar.

MathPage: From Word to the Web

Another important new feature in MathType 5.0 is our new MathPage technology for creating web pages containing math from Microsoft Word documents. First, though, let's discuss the problem that MathPage was invented to solve.

Putting Math on the Web is Hard!

Putting documents containing math on the web has always been a real challenge. Most people that have no need to deal with math in their web pages have a hard time understanding this, so we'll review the problems trying to simply type math in as HTML:

Math uses lots of symbols that are not in the usual fonts installed on the browsing user's system.
HTML does not have sufficient facilities to lay out mathematical formulas. It allows superscripts and subscripts, but that's about it.
Although modern HTML is built around Unicode technology for representing characters, browsers don't fully implement it. Also, many math characters are not in Unicode anyway.

One solution is to create GIF images for each equation. MathType, in fact, is one of the best tools around for doing this. The GIFs it creates are smaller and more accurately sized than simply taking a screen shot, for example. Also, the font and character problems are solved as a GIF needs no fonts for proper display. However, GIF equations have their own set of problems:

HTML and CSS do not provide an easy way to make an equation GIF sit on the baseline of the line of text in which they are embedded. This is another problem that CSS experts that have never tried it find very hard to believe, but this is crucial to good-looking math pages.
When a web page is printed, the GIF equations will look pixilated as they have the same resolution as the screen, while the normal HTML text is printed with the full resolution of the printer. Equations often contain very small accents, superscripts, and subscripts that are hard to see on-screen, so it is particularly irritating when they don't look any better when printed.
Browsing computers' screen resolution may vary, so it is difficult to make the web page look good for all users.
The authoring process is somewhat tedious as each GIF has to be created, saved to disk, and imported into the web page.

Since many of our users create technical documents using Microsoft Word, one obvious thing to try is Word's Save as Web Page command. Unfortunately, it doesn't do a very good job either. A little later, we'll let you compare a Word-generated web page with one generated using MathPage from the same document.

MathPage: Our Solution

MathType has included additional commands on a MathType menu within Microsoft Word for years. With MathType 5.0, we've added the Export to MathPage command. MathPage works by pre-processing the Word document, invoking Word's Save as Web Page feature, then post-processing the result. We improve the built-in Save as Web Page functionality using several techniques:

We give the user the choice of generating math symbols and equations as GIF images or MathML. In this section, we'll restrict our discussion to the GIF choice and leave MathML for a later section.
We search the original Word document for symbols that we know browsers will have trouble with and replace them with GIF images.
We use MathType's GIF generation code, rather than Word's. This gives us more control over the process.
For each symbol and equation, we generate several GIFs at different resolutions. This allows us to adapt the page within the user's browser to the screen resolution. Also, one of the GIFs is at 300 dpi, and is used when the page is printed to give laser printer quality. Finally, one resolution is used to support our MathZoom feature.
JavaScript code is used to adapt the page to the user's browser and screen resolution, and to baseline-align each equation and symbol.
We convert MathType's equation numbering into appropriate hyperlinks within the generated page.
MathType's internal equation data is stored inside each equation GIF. This allows the user viewing a page to drag-and-drop any equation into their own copy of MathType to use in creating their own documents.
No plug-ins or fonts are required to view the page.

MathZoom

As pointed out above, one of the problems with viewing math on the web is that small accents, subscripts, and superscripts can often be hard to read. With MathZoom, we have come up with a unique solution to this problem. In a MathPage-generated web page, the user can click on any equation to see it expanded in a "tooltip" style familiar to Windows users. Be sure to try it out when you view the MathPage sample in the next section.

Compare Word's Web page with MathPage's page

Just compare the quality of a web page created with Word's Save as Web Page... with the same page created using MathType 5's MathPage feature.

MathPage and MathML

MathPage technology will also allow you to save a Word document as an HTML web page containing MathML islands for the equations and symbols. MathML is the XML-based standard for publishing Math on the Web. MathML can be viewed in supporting browsers like Netscape and Mozilla, and popular MathML viewing software such as Design Science's MathPlayer™ and WebEQ Math Viewer.

New Commands for Microsoft Word

Earlier versions of MathType included MathType-specific commands for Microsoft Word. Now, in addition to our new MathPage technology that converts Word documents to web pages, MathType 5 includes several other new commands for Word. All commands are located on a MathType menu inserted into Word's menubar, and the most commonly used commands are also located on a handy MathType toolbar:

The toolbar contains commands for inserting inline and display equations, including left and right-numbered display equations. It also has commands for inserting equation numbers and references, and exporting to MathPage. Other commands on the MathType menu include

Export Equations

The powerful Export Equations command allows you to easily export the equations in a Word document into a folder as individual EPS, GIF, or WMF files, making it is easier than ever to work with page layout programs (such as QuarkXPress, InDesign and PageMaker), and HTML-authoring tools.

Equation Numbering

MathType 5 includes additional options for numbering equations. In addition to section and equation numbers, you can now optionally include chapter numbers, more custom number formats and the ability to set a default number format for other documents.

Unlimited Undo

Earlier versions of MathType allowed you to undo only the very last editing operation. MathType 5 now lets you undo one step at a time, all the way back to the way your equation was at the start of the editing session.

Add/Delete Matrix Rows and Columns

To help you save time, you can now add or delete rows and columns within existing matrices and tables by using the commands on the new Matrix menu.

Microsoft Office Support

MathType 5 has been thoroughly tested with Microsoft Office X and Office 2004, providing same level of functionality as with Office 98 and Office 2001.

Mac OS X Support

MathType has been tested thoroughly on Mac OS X versions 10.1 and newer.
