This element loads formulas from an XML-file. The formulas may be in one of three forms:

  • image (png,gif,jpg)
  • mathml
  • latex

All this formulas is available by the PI Formula and they will apear in formulalists, see PI Formula List .

image and latex formulas will be presented as img. latex (TeX) formulas are translated to img by means of Google Charts [13] .

The present version of WXT displays mathml formulas as MathML.
