ImageView widget to display an image that needs to be scaled up by a factor of 1.25 to 1.5 to be comfortably viewed. This makes the nearest-neighbor sampling of the image obvious and distracting. The
setAutoDownsample method on the
ImageItem instance inside of the
ImageView instance helps when a large image is scaled very small. But how can I enable anti-aliasing to improve the appearance of a small image that's being scaled up?
I have tried calling the
setAntialiasing method of the
GraphicsView instance inside the
ImageView instance, but this has no effect. It may be due to the note in the documentation:
Note that this will only affect items that do not specify their own antialiasing options.
But I cannot understand what items in the
GraphicsView might have their own options, or how to change these.
