I'm algorithmically building a QImage at double resolution, and I want to build a retina-capable QPixmap from it.
Say for instance I want to make a retina-capable image at 100x100 logical pixels. So I create a QImage at 200x200, draw some stuff into, then I want to convert it to a QPixmap at 100x100 with a devicePixelRatio of 2. Doing this... QImage image(200, 200, ...) // draw into image image.setDevicePixelRatio(2.0f); QPixmap pixmap = QPixmap::fromImage(image); ...doesn't seem to yield the proper image. Is that all that is necessary, or did I miss a step? _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
