32<h2>Description</h2>
33
34<P>The graphics hardware keeps track of a bounding box of pixel coordinates that are drawn in the Embedded Frame Buffer (EFB).&nbsp;These bounding box values can be read back by <a href="GXReadBoundingBox.html"><code>GXReadBoundingBox</code></a> to determine the area of the frame buffer to copy (using <a href="GXSetTexCopySrc.html"><code>GXSetTexCopySrc</code></a> or <a href="GXSetDispCopySrc.html"><code>GXSetDispCopySrc</code></a>). This function clears the bounding box values before a new image is drawn.</P>
