If +you retrieve a frame (pixmap) from a QCanvasSprite it will be +returned as a QCanvasPixmap. +<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 QPixmap, 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="qimageio.html">QImageIO</a>). +<p> QCanvasPixmap can have a hotspot which is defined in terms of an (x, +y) offset. When you create a QCanvasPixmap from a PNG file or from +a QImage 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="#setOffset">setOffset</a>(). When the QCanvasPixmap is used +in a <a href="qcanvassprite.html">QCanvasSprite</a>, the offset position is the point at +<a href="qcanvasitem.html#x">QCanvasItem::x</a>() and <a href="qcanvasitem.html#y">QCanvasItem::y</a>(), not the top-left corner of +the pixmap. +<p> Note that for QCanvasPixmap objects created by a QCanvasSprite, the +position of each QCanvasPixmap object is set so that the hotspot +stays in the same position. +<p> <p>See also <a href="qcanvaspixmaparray.html">QCanvasPixmapArray</a>, <a href="qcanvasitem.html">QCanvasItem</a>, <a href="qcanvassprite.html">QCanvasSprite</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="QCanvasPixmap"></a>QCanvasPixmap::QCanvasPixmap ( const <a href="qstring.html">QString</a> & datafilename ) +</h3> +Constructs a QCanvasPixmap that uses the image stored in <em>datafilename</em>. + +<h3 class=fn><a name="QCanvasPixmap-2"></a>QCanvasPixmap::QCanvasPixmap ( const <a href="qimage.html">QImage</a> & image ) +</h3> +Constructs a QCanvasPixmap from the image <em>image</em>. + +<h3 class=fn><a name="QCanvasPixmap-3"></a>QCanvasPixmap::QCanvasPixmap ( const <a href="qpixmap.html">QPixmap</a> & pm, const <a href="qpoint.html">QPoint</a> & offset ) +</h3> +Constructs a QCanvasPixmap from the pixmap <em>pm</em> using the offset +<em>offset</em>. + +<h3 class=fn><a name="~QCanvasPixmap"></a>QCanvasPixmap::~QCanvasPixmap () +</h3> +Destroys the pixmap. + +<h3 class=fn>int <a name="offsetX"></a>QCanvasPixmap::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>QCanvasPixmap::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>QCanvasPixmap::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 QCanvasSprites are +currently showing this pixmap. + +<!-- eof --> +<hr><p> +This file is part of the <a href="index.html">Qt toolkit</a>. +Copyright © 1995-2007 +<a href="http://www.trolltech.com/">Trolltech</a>.
