    2020Currently it supports the following **features**:
    21 * Basic function: Convert equations into graphics
    22 * Font and background color can be chosen by you in the admin panel (alpha-transparency included, but if you are using Microsoft Internet Explorer you will need version 7 or greater to display the images correctly)
    23 * Font size default value can be set, but also changed for every single image if necessary
    24 * If you just want to output a formula there is a "noparse" attribute that will output the pure text nicely formatted
    25 * Saves the images on the webspace, which saves processor time
    26 * Clear image cache and let all images be regenerated by admin panel
