It works + jointly with the other driver (known as "client"), using its pixel, line and text functions to simulate arcs, sectors, + polygons, boxes, and fillings with styles.</p> + <p><b>Important:</b> All simulation primitives are based in the client's Pixel, Image and/or Line functions.</p> + +<h3>Use</h3> + + <p>The Simulation driver is used in several parts of the CD library.</p> + <p>In many drivers, the behavior of a given primitive may not be the expected. Usually this is documented in the + manual. If you wish to activate the simulation of a primitive, simply call function <strong> + <font face="Courier"><a href="../func/init.html#cdSimulate">cdSimulate</a></font></strong> + with the code of the primitive to be simulated.</p> + +<h3>Behavior of Functions</h3> +<h4>Clipping</h4> +<ul> + <li>Clipping is not implemented in the simulation base driver.

For other fonts, it will first check + for a font map added using the attribute <strong>ADDFONTMAP</strong>, if + failed it will try to load the type_face name without any change, if fail it + will add the style suffix to the type_face and try to load again.
