<h2>Detailed Description</h2>
<p>The QGraphicsPixmapItem class provides a pixmap item that you can add to a <a href="qgraphicsscene.html">QGraphicsScene</a>.</p>
<p>To set the item's pixmap, pass a <a href="qpixmap.html">QPixmap</a> to QGraphicsPixmapItem's constructor, or call the <a href="qgraphicspixmapitem.html#setPixmap">setPixmap</a>() function. The <a href="qgraphicspixmapitem.html#pixmap">pixmap</a>() function returns the current pixmap.</p>
<p>QGraphicsPixmapItem uses pixmap's optional alpha mask to provide a reasonable implementation of <a href="qgraphicspixmapitem.html#boundingRect">boundingRect</a>(), <a href="qgraphicspixmapitem.html#shape">shape</a>(), and <a href="qgraphicspixmapitem.html#contains">contains</a>().</p>
<p class="centerAlign"><img src="images/graphicsview-pixmapitem.png" alt="" /></p><p>The pixmap is drawn at the item's (0, 0) coordinate, as returned by <a href="qgraphicspixmapitem.html#offset">offset</a>(). You can change the drawing offset by calling <a href="qgraphicspixmapitem.html#setOffset">setOffset</a>().</p>
<p>You can set the pixmap's transformation mode by calling <a href="qgraphicspixmapitem.html#setTransformationMode">setTransformationMode</a>(). By default, <a href="qt.html#TransformationMode-enum">Qt::FastTransformation</a> is used, which provides fast, non-smooth scaling. <a href="qt.html#TransformationMode-enum">Qt::SmoothTransformation</a> enables <a href="qpainter.html#RenderHint-enum">QPainter::SmoothPixmapTransform</a> on the painter, and the quality depends on the platform and viewport. The result is usually not as good as calling QPixmap::scale() directly. Call <a href="qgraphicspixmapitem.html#transformationMode">transformationMode</a>() to get the current transformation mode for the item.</p>
