<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>All drawing operations in GDK take a graphics context (<a class="el" href="classGdk_1_1GC.html" title="All drawing operations in GDK take a graphics context (GC) argument.">GC</a>) argument. </p>
<p>A graphics context encapsulates information about the way things are drawn, such as the foreground color or line width. By using graphics contexts, the number of arguments to each drawing call is greatly reduced, and communication overhead is minimized, since identical arguments do not need to be passed repeatedly. </p>
