Planned maintenance has been done but it did not solve the problem. So work will continue on this and a new time for trying updates will be announced asap.
QImage in QGraphicsScene is pixelated when zooming in
-
I created a simple custom
QGraphicsScenein which user can zoom in and out by keeping pressedCtrlkey and moving the mouse wheel up and down.
I have to addQImages to myQGraphicsScene. To achieve that, I first convert them toQPixmapwith the functionQPixmap::fromImage().
However those pixmaps are really pixelated if I zoom in. Is there a way to create vectorial images fromQImageand render them to the scene?

hi
As far as I know there is no build in raster to vector conversion.
Also many images are not really good for it.Im wonder if QGraphicsScene is scaling images with best quality.
