Math
From FreeMind
Jump to navigationJump to search
One requested feature is that FreeMind supports typesetting of mathematical formulas, perhaps in LaTeX.
FreeMind 0.9.0 beta14 is delivered with a plugin of mathematical formulas, based on HotEqn component.
Some users use their private extension that renders a tag < latex > when inside a node, using dvipng tool.[1]
License
All the considered components for rendering math should have GNU GPL license, or at least a compatible open-source license.
Formats
Formats:
| Format | Verbosity | Note |
|---|---|---|
| LaTeX | Low | Only a subset can be realistically supported. Used by Wikipedia encyclopedia, and Mediawiki wiki engine. Scientists around the world already know parts of it by heart. |
| MathML | High | Is an XML vocabulary. Is tedious to edit in the plain text form. |
Engines
The following components are capable of rendering mathematical formulas.
| Name | Lang. | License | Format | Viewing | WYSIWYG Editing | Smooth Fonts | Inline Math | URL | Note | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| HotEqn | Java | GPL | Subset of LaTeX | Yes | No | No | No | [2] | Has been chosen by Dimitry in the plugin of FreeMind 0.9.0 beta 15. Source code for download: [3] | ||||||||||
| ShowMath | Java | ? | Subset of LaTeX | [4] | |||||||||||||||
| Jex | Java | GPL V2 | Subset of LaTeX, MathML, Mathtype | [5] | |||||||||||||||
| Jmath | Java | ? | ? | [6] | |||||||||||||||
| TeX & Dvipng | C | Dvipng: GPL V2+ | LaTeX | Yes | No | Yes | Yes | [7][8] | Requires installation of LaTeX, which is difficult to install. | ||||||||||
| JMathTeX | Java | GPL V2+; Apache style | Subset of LaTeX | Yes | No | Yes | Yes | [9][10] | Renders LaTeX (or TeX?) into Java class Image and thus also into PNG. Depends on JDOM, which has an Apache-style license. JMathTeX itself has GNU GPL V2+. Latest release: 0.7pre on May 2, 2007. | Mirai Math | Java | GPL V2+ | Subset of LaTeX | Yes | No | Yes | Yes | [11][12] | WYSIWYG math field/workbook editor. |
Inline math means that the math can be placed inside the text of FreeMind's long lode or even of note. Such a feature is enabled by any engine, Java or non-Java, that renders the math into PNG.
