I have had some success with these instructions:
	outputImg = QPixmap(xVp,yVp)
	painter = QPainter(outputImg)
	targetrect = QRectF(0,0,xVp,yVp)
	sourcerect = QRectF(-20,-20,xVp+50,yVp+50)
	scene.render(painter,targetrect, sourcerect)
	.....

it seems to be determinant the definition of targetrect & sourcerect; I
don't have complete control on the saving procedure but this is
a good improvement (for me) :-)
