<hr><h2><a name="details"></a>Detailed Description</h2>
The QCanvasSprite class provides an animated moving pixmap on a <a href="qcanvas.html">QCanvas</a>.
<p>
A "sprite" is an image object that moves around independently of
foreground and background. On a QCanvas, everything moves around
independently of the foreground and background, so a QCanvasSprite
is just a image whose API makes it simpler to use animation and a
hot spot.
<p>QCanvasSprite draws very fast, at the cost of some memory.

<h3 class="fn">int<a name="510e4b"></a>QCanvasSprite::absX()const <code>[protected]</code></h3>
<p>The absolute horizontal position of the sprite. This is
the pixel position of the left edge of the image, as it takes into
account the offset.
<h3 class="fn">int<a name="ea41ce"></a>QCanvasSprite::absX(intnx)const <code>[protected]</code></h3>
<p>The absolute horizontal position of the sprite, if it was moved to
<em>nx.</em>

<h3 class="fn">int<a name="a29b91"></a>QCanvasSprite::absY()const <code>[protected]</code></h3>
<p>The absolute vertical position of the sprite. This is
the pixel position of the top edge of the image, as it takes into
account the offset.
<h3 class="fn">int<a name="2bc7cd"></a>QCanvasSprite::absY(intny)const <code>[protected]</code></h3>
<p>The absolute vertical position of the sprite, if it was
moved to <em>ny.</em>

<p>The bottom edge of the sprite image.
<p>See also <a href="#2bc7cd">absY</a>().
<h3 class="fn">int<a name="064ef2"></a>QCanvasSprite::absY2(intny)const <code>[protected]</code></h3>
<p>The bottom edge of the sprite image, <em>if</em> the sprite was moved to <em>ny.</em>
<p>See also <a href="#2bc7cd">absY</a>().
<h3 class="fn"><a href="qrect.html">QRect</a><a name="107def"></a>QCanvasSprite::boundingRect()const <code>[virtual]</code></h3>
<p>Returns the bounding rectangle of pixels covered by the sprite.
This assumes that the images are tightly cropped (ie. do not have
transparent pixels all along a side).
<p>Reimplemented from <a href="qcanvasitem.html#156958">QCanvasItem.</a>
<h3 class="fn">bool<a name="6e05e0"></a>QCanvasSprite::collidesWith(const<a href="qcanvasitem.html">QCanvasItem</a>*i)const <code>[virtual]</code></h3>

<h3 class="fn">void<a name="ae5194"></a>QCanvasSprite::draw(<a href="qpainter.html">QPainter</a>&painter) <code>[virtualprotected]</code></h3>
<p>Draws the current image of the sprite at its current position,
as given by <a href="#150d57">image</a>() and <a href="qcanvasitem.html#e0e6af">x</a>(), <a href="qcanvasitem.html#2eabbd">y</a>().
<p>Reimplemented from <a href="qcanvasitem.html#cce3d0">QCanvasItem.</a>
<h3 class="fn">int<a name="5a45fd"></a>QCanvasSprite::frame()const</h3>

<p>The height of the sprite, in its current image.
<p>See also <a href="#5a45fd">frame</a>().
<h3 class="fn"><a href="qcanvaspixmap.html">QCanvasPixmap</a>*<a name="150d57"></a>QCanvasSprite::image()const <code>[protected]</code></h3>
<p>Returns the current image frame.

<p>The image the sprite <em>will</em> have after <a href="qcanvasitem.html#3bf03d">advance</a>(1) is called.
Be default this is the same as <a href="#150d57">image</a>().

<p>Set both the position and the frame of the sprite.
<h3 class="fn">void<a name="d9c6f2"></a>QCanvasSprite::move(doublex, doubley)</h3>
