Some versions of ImageMagick fail to process the transparency command properly. If you find that this is causing problems for you then in class.latexrender.php<\/strong> remove the transparency command<\/p>\n

-transparent \"#FFFFFF\"<\/code><\/p>\n

so<\/p>\n

\/\/ imagemagick convert ps to image and trim picture
\n$command = $this->_convert_path.\" -density \".$this->_formula_density.\" -trim -transparent \"#FFFFFF\" \".$this->_tmp_filename.\".ps \".$this->_tmp_filename.\".\".$this->_image_format;<\/code><\/p>\n

becomes<\/p>\n
