The integrated Wiki rendering component which is currently used in the repository type Wiki can display mathematics in Web pages. Is is based on the great javascript project called jsMath ( jsMath Website). It tries to render the formular with special mathematics fonts, if the fonts are not installed it uses images provided by the javascript library. As it is a huge number of images (20'000) we do not provide them unpacked in our distro as it makes unzipping the distro too long. Therefore you have to run 'mvn olat:font' to unzip the font files to the appropriate location.
