<h2>Detailed Description</h2>
<p>This class is used in conjunction with the <a href="qpainter.html#drawPixmapFragments">QPainter::drawPixmapFragments</a>() function to specify how a pixmap, or sub-rect of a pixmap, is drawn.</p>
<p>The <i>sourceLeft</i>, <i>sourceTop</i>, <i>width</i> and <i>height</i> variables are used as a source rectangle within the pixmap passed into the <a href="qpainter.html#drawPixmapFragments">QPainter::drawPixmapFragments</a>() function. The variables <i>x</i>, <i>y</i>, <i>width</i> and <i>height</i> are used to calculate the target rectangle that is drawn. <i>x</i> and <i>y</i> denotes the center of the target rectangle. The <i>width</i> and <i>height</i> in the target rectangle is scaled by the <i>scaleX</i> and <i>scaleY</i> values. The resulting target rectangle is then rotated <i>rotation</i> degrees around the <i>x</i>, <i>y</i> center point.</p>
