You would want to use methods from QGraphicsView or QGraphicsScene to
render a given rectangle using a painter that is targetting a QImage:
void*render <http://doc.qt.nokia.com/4.7/qgraphicsview.html#render>* (
QPainter * *painter*, const QRectF & *target* = QRectF(), const QRect & *
source* = QRect(), Qt::AspectRatioMode *aspectRatioMode* =
Then the image could be passed to the clipboard.

Ahh... those decisions are still out of our hands. The bit depth of the
images is controlled by the rendering library---which is still Poppler at
the moment but could change to MuPDF in the distant future.
