QGraphicsPixmapItem Class Reference |
Constant | Value | Description |
---|---|---|
QGraphicsPixmapItem::MaskShape | 0 | The shape is determined by calling QPixmap::mask(). This shape includes only the opaque pixels of the pixmap. Because the shape is more complex, however, it can be slower than the other modes, and uses more memory. |
QGraphicsPixmapItem::BoundingRectShape | 1 | The shape is determined by tracing the outline of the pixmap. This is the fastest shape mode, but it does not take into account any transparent areas on the pixmap. |
QGraphicsPixmapItem::HeuristicMaskShape | 2 | The shape is determine by calling QPixmap::createHeuristicMask(). The performance and memory consumption is similar to MaskShape. |
Constructs a QGraphicsPixmapItem. parent is passed to QGraphicsItem's constructor.
See also QGraphicsScene::addItem().
Constructs a QGraphicsPixmapItem, using pixmap as the default pixmap. parent is passed to QGraphicsItem's constructor.
See also QGraphicsScene::addItem().
Destroys the QGraphicsPixmapItem.
Returns the pixmap item's offset, which defines the point of the top-left corner of the pixmap, in local coordinates.
See also setOffset().
Returns the item's pixmap, or an invalid QPixmap if no pixmap has been set.
See also setPixmap().
Sets the pixmap item's offset to offset. QGraphicsPixmapItem will draw its pixmap using offset for its top-left corner.
See also offset().
This is an overloaded member function, provided for convenience.
This convenience function is equivalent to calling setOffset(QPointF(x, y)).
This function was introduced in Qt 4.3.
Sets the item's pixmap to pixmap.
See also pixmap().
Sets the item's shape mode to mode. The shape mode describes how QGraphicsPixmapItem calculates its shape. The default mode is MaskShape.
See also shapeMode() and ShapeMode.
Sets the pixmap item's transformation mode to mode, and toggles an update of the item. The default mode is Qt::FastTransformation, which provides quick transformation with no smoothing.
Qt::SmoothTransformation enables QPainter::SmoothPixmapTransform on the painter, and the quality depends on the platform and viewport. The result is usually not as good as calling QPixmap::scale() directly.
See also transformationMode().
Returns the item's shape mode. The shape mode describes how QGraphicsPixmapItem calculates its shape. The default mode is MaskShape.
See also setShapeMode() and ShapeMode.
Returns the transformation mode of the pixmap. The default mode is Qt::FastTransformation, which provides quick transformation with no smoothing.
See also setTransformationMode().
