  <summary>Specifies the ratio of the height of an <glossary tag="EPS">EPS object's</glossary> <property tag="postScript">PostScript</property> bounding box to the object's screen height.</summary>
  <examples>
    <example>set the yScale of last EPS to 2 <i>-- PS image twice the height of screen</i></example>
    <example>set the yScale of EPS "Guido" to 0.25 <i>-- one-fourth the height</i></example>
