TQCanvasSprites are used to show pixmaps on TQCanvases and hold their pixmaps in a TQCanvasPixmapArray. If you retrieve a frame (pixmap) from a TQCanvasSprite it will be returned as a TQCanvasPixmap. .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 TQImage and one a file name that refers to a file in any supported file format (see TQImageIO). .PP 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 TQImage::offset(), the offset() is initialized appropriately, otherwise the constructor leaves it at (0, 0). You can set it later using setOffset(). When the TQCanvasPixmap is used in a TQCanvasSprite, the offset position is the point at TQCanvasItem::x() and TQCanvasItem::y(), not the top-left corner of the pixmap. .PP 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. .PP See also TQCanvasPixmapArray, TQCanvasItem, TQCanvasSprite, Graphics Classes, and Image Processing Classes. .SH MEMBER FUNCTION DOCUMENTATION .SH "TQCanvasPixmap::TQCanvasPixmap ( const TQString & datafilename )" Constructs a TQCanvasPixmap that uses the image stored in \fIdatafilename\fR. .SH "TQCanvasPixmap::TQCanvasPixmap ( const TQImage & image )" Constructs a TQCanvasPixmap from the image \fIimage\fR. .SH "TQCanvasPixmap::TQCanvasPixmap ( const QPixmap & pm, const QPoint & offset )" Constructs a TQCanvasPixmap from the pixmap \fIpm\fR using the offset \fIoffset\fR. .SH "TQCanvasPixmap::~TQCanvasPixmap ()" Destroys the pixmap. .SH "int TQCanvasPixmap::offsetX () const" Returns the x-offset of the pixmap's hotspot. .PP See also setOffset(). .SH "int TQCanvasPixmap::offsetY () const" Returns the y-offset of the pixmap's hotspot. .PP See also setOffset(). .SH "void TQCanvasPixmap::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 TQCanvasSprites are currently showing this pixmap. .SH "SEE ALSO" .BR http://doc.trolltech.com/tqcanvaspixmap.html .BR http://www.trolltech.com/faq/tech.html .SH COPYRIGHT Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
