# Using the TLatex class

    // This macro draws 4 Latex-style formula in a canvas and prints the canvas
    // as a Postscript file.
    // Note that this macro relies on a first implementation of the TLatex class.
    // There are still some discrepancies between the result on the screen
    // and the result on Postscript.
