<hr><a name="details"></a><h2>Detailed Description</h2>
The TQCanvasPixmap class provides pixmaps for TQCanvasSprites.
<p>
<p> If you want to show a single pixmap on a <a href="qcanvas.html">TQCanvas</a> use a
<a href="qcanvassprite.html">TQCanvasSprite</a> with just one pixmap.
<p> When pixmaps are inserted into a <a href="qcanvaspixmaparray.html">TQCanvasPixmapArray</a> they are held
as TQCanvasPixmaps. <a href="qcanvassprite.html">TQCanvasSprite</a>s are used to show pixmaps on
<a href="qcanvas.html">TQCanvas</a>es and hold their pixmaps in a TQCanvasPixmapArray. If
you retrieve a frame (pixmap) from a TQCanvasSprite it will be
returned as a TQCanvasPixmap.
<p> The pixmap is a <a href="qpixmap.html">TQPixmap</a> and can only be set in the constructor.
There are three different constructors, one taking a TQPixmap, one
a <a href="qimage.html">TQImage</a> and one a file name that refers to a file in any
supported file format (see <a href="qimageio.html">TQImageIO</a>).
<p> TQCanvasPixmap can have a hotspot which is defined in terms of an (x,
y) offset. When you create a TQCanvasPixmap from a PNG file or from
a TQImage that has a <a href="qimage.html#offset">TQImage::offset</a>(), the offset() is initialized
appropriately, otherwise the constructor leaves it at (0, 0). You
can set it later using <a href="#setOffset">setOffset</a>(). When the TQCanvasPixmap is used
in a <a href="qcanvassprite.html">TQCanvasSprite</a>, the offset position is the point at
<a href="qcanvasitem.html#x">TQCanvasItem::x</a>() and <a href="qcanvasitem.html#y">TQCanvasItem::y</a>(), not the top-left corner of
the pixmap.
<p> Note that for TQCanvasPixmap objects created by a TQCanvasSprite, the
position of each TQCanvasPixmap object is set so that the hotspot
stays in the same position.
<p> <p>See also <a href="qcanvaspixmaparray.html">TQCanvasPixmapArray</a>, <a href="qcanvasitem.html">TQCanvasItem</a>, <a href="qcanvassprite.html">TQCanvasSprite</a>, <a href="graphics.html">Graphics Classes</a>, and <a href="images.html">Image Processing Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQCanvasPixmap"></a>TQCanvasPixmap::TQCanvasPixmap ( const <a href="qstring.html">TQString</a> & datafilename )
</h3>
Constructs a TQCanvasPixmap that uses the image stored in <em>datafilename</em>.
<h3 class=fn><a name="TQCanvasPixmap-2"></a>TQCanvasPixmap::TQCanvasPixmap ( const <a href="qimage.html">TQImage</a> & image )
</h3>
Constructs a TQCanvasPixmap from the image <em>image</em>.
<h3 class=fn><a name="TQCanvasPixmap-3"></a>TQCanvasPixmap::TQCanvasPixmap ( const <a href="qpixmap.html">TQPixmap</a> & pm, const <a href="qpoint.html">TQPoint</a> & offset )
</h3>
Constructs a TQCanvasPixmap from the pixmap <em>pm</em> using the offset
<em>offset</em>.
<h3 class=fn><a name="~TQCanvasPixmap"></a>TQCanvasPixmap::~TQCanvasPixmap ()
</h3>
Destroys the pixmap.
<h3 class=fn>int <a name="offsetX"></a>TQCanvasPixmap::offsetX () const
</h3>
<p> Returns the x-offset of the pixmap's hotspot.
<p> <p>See also <a href="#setOffset">setOffset</a>().
<h3 class=fn>int <a name="offsetY"></a>TQCanvasPixmap::offsetY () const
</h3>
<p> Returns the y-offset of the pixmap's hotspot.
<p> <p>See also <a href="#setOffset">setOffset</a>().
<h3 class=fn>void <a name="setOffset"></a>TQCanvasPixmap::setOffset ( int x, int y )
</h3>
<p> Sets the offset of the pixmap's hotspot to (<em>x</em>, <em>y</em>).
<p> <b>Warning:</b> Do not call this function if any TQCanvasSprites are
currently showing this pixmap.
