It looks to me like at present (Qt 5.4) the various devicePixelRatio() functions on Windows only return 1.0 or 2.0. But Windows systems can be at fractional ratios- will 5.5 address that?
It also appears that drawing a QPixmap or QImage with a fractional ratio actually works, but we can't discover that situation easily. -John Weeks WaveMetrics, Inc. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
