This is wrong because we don't really need to scale. We already have the estimated page dimentions in pixels, so taking the quotient of the printer DPI and screen DPI and then scaling (probably up) our rendered widgets via the QPainter introduces blur (due to the oversampling), and a performance penalty. By rendering at the exact dimensions we ensure that the widgets are crisp at a 100% printout. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
