QCanvasSprites are used to show pixmaps on QCanvases and hold their pixmaps in a QCanvasPixmapArray. If you retrieve a frame (pixmap) from a QCanvasSprite it will be returned as a QCanvasPixmap. +.PP +The pixmap is a QPixmap and can only be set in the constructor. There are three different constructors, one taking a QPixmap, one a QImage and one a file name that refers to a file in any supported file format (see QImageIO). +.PP +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 QImage::offset(), the offset() is initialized appropriately, otherwise the constructor leaves it at (0, 0). You can set it later using setOffset(). When the QCanvasPixmap is used in a QCanvasSprite, the offset position is the point at QCanvasItem::x() and QCanvasItem::y(), not the top-left corner of the pixmap. +.PP +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. +.PP +See also QCanvasPixmapArray, QCanvasItem, QCanvasSprite, Graphics Classes, and Image Processing Classes. +.SH MEMBER FUNCTION DOCUMENTATION +.SH "QCanvasPixmap::QCanvasPixmap ( const QString & datafilename )" +Constructs a QCanvasPixmap that uses the image stored in \fIdatafilename\fR. +.SH "QCanvasPixmap::QCanvasPixmap ( const QImage & image )" +Constructs a QCanvasPixmap from the image \fIimage\fR. +.SH "QCanvasPixmap::QCanvasPixmap ( const QPixmap & pm, const QPoint & offset )" +Constructs a QCanvasPixmap from the pixmap \fIpm\fR using the offset \fIoffset\fR. +.SH "QCanvasPixmap::~QCanvasPixmap ()" +Destroys the pixmap. +.SH "int QCanvasPixmap::offsetX () const" +Returns the x-offset of the pixmap's hotspot. +.PP +See also setOffset(). +.SH "int QCanvasPixmap::offsetY () const" +Returns the y-offset of the pixmap's hotspot. +.PP +See also setOffset(). +.SH "void QCanvasPixmap::setOffset ( int x, int y )" +Sets the offset of the pixmap's hotspot to (\fIx\fR, \fIy\fR). +.PP +\fBWarning:\fR Do not call this function if any QCanvasSprites are +currently showing this pixmap. + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/qcanvaspixmap.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
