QCanvasPixmap - Pixmaps for QCanvasSprites
#include <qcanvas.h> Inherits QPixmap. Public Members QCanvasPixmap ( const QString & datafilename ) QCanvasPixmap ( const QImage & image ) QCanvasPixmap ( const QPixmap & pm, const QPoint & offset ) ~QCanvasPixmap () int offsetX () const int offsetY () const void setOffset ( int x, int y )
The QCanvasPixmap class provides pixmaps for QCanvasSprites. If you want to show a single pixmap on a QCanvas use a QCanvasSprite with just one pixmap. When pixmaps are inserted into a QCanvasPixmapArray they are held as QCanvasPixmaps. 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. 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). 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. 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. See also QCanvasPixmapArray, QCanvasItem, QCanvasSprite, Graphics Classes, and Image Processing Classes.
QCanvasPixmap::QCanvasPixmap ( const QString & datafilename ) Constructs a QCanvasPixmap that uses the image stored in datafilename. QCanvasPixmap::QCanvasPixmap ( const QImage & image ) Constructs a QCanvasPixmap from the image image. QCanvasPixmap::QCanvasPixmap ( const QPixmap & pm, const QPoint & offset ) Constructs a QCanvasPixmap from the pixmap pm using the offset offset. QCanvasPixmap::~QCanvasPixmap () Destroys the pixmap. int QCanvasPixmap::offsetX () const Returns the x-offset of the pixmap's hotspot. See also setOffset(). int QCanvasPixmap::offsetY () const Returns the y-offset of the pixmap's hotspot. See also setOffset(). void QCanvasPixmap::setOffset ( int x, int y ) Sets the offset of the pixmap's hotspot to (x, y). Warning: Do not call this function if any QCanvasSprites are currently showing this pixmap.
