Detailed Description

QGraphicsScene provides certain parameters to help control how the scale should be applied.

The origin is the point that the item is scaled from (i.e., it stays fixed relative to the parent as the rest of the item grows). By default the origin is QPointF (0, 0).

The parameters xScale , yScale , and zScale describe the scale factors to apply in horizontal, vertical, and depth directions. They can take on any value, including 0 (to collapse the item to a point) or negative value. A negative xScale value will mirror the item horizontally. A negative yScale value will flip the item vertically. A negative zScale will flip the item end for end.
