Multitouch on QGraphicsPixmapItem
I tried the "Example of Multi Touch":http://www.trinitydesktop.org/docs/qt4/multitouch-pinchzoom.html. In this example, transformation is applied on QGraphicsView. But, I want apply transformation only on image which is of QGraphicsPixmapItem. I can easily doing transformation on QGraphicsPixmapItem. But, transformation is only applied on Bottom Right part of QGraphicsPixmapItem. I want this transformation on Top Left part of QGraphicsPixmapItem. What should i do for this ?
