<h2>Detailed Description</h2>
<p>The Q3CanvasPixmap class provides pixmaps for Q3CanvasSprites.</p>
<p>If you want to show a single pixmap on a <a href="q3canvas.html">Q3Canvas</a> use a <a href="q3canvassprite.html">Q3CanvasSprite</a> with just one pixmap.</p>
<p>When pixmaps are inserted into a <a href="q3canvaspixmaparray.html">Q3CanvasPixmapArray</a> they are held as Q3CanvasPixmaps. <a href="q3canvassprite.html">Q3CanvasSprite</a>s are used to show pixmaps on <a href="q3canvas.html">Q3Canvas</a>es and hold their pixmaps in a <a href="q3canvaspixmaparray.html">Q3CanvasPixmapArray</a>. If you retrieve a frame (pixmap) from a <a href="q3canvassprite.html">Q3CanvasSprite</a> it will be returned as a Q3CanvasPixmap.</p>
<p>The pixmap is a <a href="qpixmap.html">QPixmap</a> and can only be set in the constructor. There are three different constructors, one taking a <a href="qpixmap.html">QPixmap</a>, one a <a href="qimage.html">QImage</a> and one a file name that refers to a file in any supported file format (see <a href="qimagereader.html">QImageReader</a>).</p>
<p>Q3CanvasPixmap can have a hotspot which is defined in terms of an (x, y) offset. When you create a Q3CanvasPixmap from a PNG file or from a <a href="qimage.html">QImage</a> that has a <a href="qimage.html#offset">QImage::offset</a>(), the offset() is initialized appropriately, otherwise the constructor leaves it at (0, 0). You can set it later using <a href="q3canvaspixmap.html#setOffset">setOffset</a>(). When the Q3CanvasPixmap is used in a <a href="q3canvassprite.html">Q3CanvasSprite</a>, the offset position is the point at <a href="q3canvasitem.html#x">Q3CanvasItem::x</a>() and <a href="q3canvasitem.html#y">Q3CanvasItem::y</a>(), not the top-left corner of the pixmap.</p>
<p>Note that for Q3CanvasPixmap objects created by a <a href="q3canvassprite.html">Q3CanvasSprite</a>, the position of each Q3CanvasPixmap object is set so that the hotspot stays in the same position.</p>
<p>See also <a href="q3canvaspixmaparray.html">Q3CanvasPixmapArray</a>, <a href="q3canvasitem.html">Q3CanvasItem</a>, <a href="q3canvassprite.html">Q3CanvasSprite</a>, <a href="http://doc.trolltech.com/qtcanvas">QtCanvas</a>, and <a href="graphicsview-porting.html">Porting to Graphics View</a>.</p>
