Bill Baxter’s LaTeX in WordPress with PHP5.x

Ulf Hamster’s  Verwendung von LatexRender für Webpages  Google’s translation into English:  Use of latex rendering for web pages

Many thanks for these helpful articles. If you know of other articles that improve LatexRender do let me know.

A couple of the services are unable to process the plus sign correctly, probably because the symbol is changed at some stage. In those cases + needs to be replaced by %2B, thus

gives

gives

Similar changes may have to be made for other symbols, though it would be better if the services themselves could do the necessary translation.

The number of links keeps growing and I’ll try to add new ones as they arise.

In class.latexrender.php look for the line
var $_image_format = "gif"; //change to png if you prefer
and change it to
var $_image_format = "png";

You could instead use an older version of ImageMagick (such as version 6.2.9) or bypass ImageMagick altogether with dvipng, which is the method that WordPress.com uses.

Discussion of this problem can be found here. Let’s hope the bug is resolved in the near future.

WordPress.com uses its customised version of LatexRender to render the snippets of LaTeX, but LaTeX2WP will help prepare long texts. LaTeX2WP takes a TeX file and reformats it adding the required HTML codes and latex tags so that you can have, for example, numbered equations and dispayed equations. This is particularly useful for long mathematical notes containing lots of mathematics. It’s used by, amongst others, the Fields medallist Terence Tao for his blog at What’s new.

You can read more about LaTeX2WP and download it from LaTeX to WordPress

• Latex Math is a WordPress plugin enabling you to add LaTeX code to your WordPress blog;
• Webtop Mania has a Mathtex bookmarklet which gives you a prompt to add LaTeX code.

This equation editor can be used in a number of ways:

1. Create the equation and then copy and paste the image into your website;
2. Fetch the code directly from CodeCogs site and use in your website like this
<img src="http://www.codecogs.com/eq.latex?\tiny \int_{-\infty }^{\infty }e^{-x^{2}}\;dx=\sqrt{\pi }" /> which gives

3. Incorporate the visual editor into your text box (for example in a forum such as phpBB) or the FCK Editor;
4. Install the complete system on your server.

Method 1 does not require any code, method 2 only requres a small amount of HTML and is particularly suitable for example for Blogger. Method 3 needs some PHP code on your site and method 4 requires LaTeX and other software to be installed on your server. Full instructions are provided at Installing the CodeCogs Equation Editor v2

Please note that if you use method 3 you should display the following banner on your page and if you use methods 2 or 3 then do please contact CodeCogs first at CodeCogs Services.
Do let CodeCogs know of any customisations or innovative uses that you make of their equation editor.
