Using LaTeX in WordPress

Poor GIF output in LatexRender

John Forkosh (author of mathTeX) has brought to my attention a bug in the latest version of ImageMagick’s convert. This is used to produce the gif image and can result in poor output with very light fonts. If you get this you can get a better result with LatexRender if you convert to a png instead.

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.
