DESCRIPTION
The QCanvasPixmap class provides a pixmap with an offset.
QImage has an offset or "hot spot", but QPixmap does not.
This class adds the notion of an offset to QPixmap as this
is very useful for the canvas sprites where QCanvasPixmap
is used. It also keeps a copy of the display mask for use
in collision detection.
Note that PNG format files already have support for an
offset.
See also QCanvasPixmapArray, QCanvasItem and
QCanvasSprite.
MEMBER FUNCTION DOCUMENTATION
QCanvasPixmap::QCanvasPixmap ( const QImage & image )
Constructs a QCanvasPixmap from an image.
QCanvasPixmap::QCanvasPixmap ( const QPixmap & pm, QPoint offset
)
Constructs a QCanvasPixmap from a pixmap and an offset.
QCanvasPixmap::QCanvasPixmap ( const QString & datafilename )
Constructs a QCanvasPixmap from an image file by loading
it.
QCanvasPixmap::~QCanvasPixmap ()
Destructs the pixmap.
int QCanvasPixmap::offsetX () const
Returns the X-offset of the pixmap.
See also setOffset().
int QCanvasPixmap::offsetY () const
Returns the Y-offset of the pixmap.
void QCanvasPixmap::setOffset ( int x, int y )
Sets the offset to (x, y).
The offset position or "hot spot" defines the origin pixel
in the image For example, if the offset is (10,5), it will
be displayed drawn 10 pixels to the left of and 5 pixels
above the actual (x,y) coordinate of the sprite.
