Practical use of special commands in DVIPDFMx Jin-Hwan Cho (The University of Suwon, Republic of Korea) ABSTRACT: Special commands in \TeX{} provides the only way to communicate arbitrary information with DVI drivers. DVIPDFM$x$, one of such drivers, translates the standard DVI output of TeX into the PDF format defined by Adobe for platform independent transmission of digital documents. In this presentation, we discuss all the special commands supported by DVIPDFM$x$ and show some practical applications for package designers as well as TeX end users.
