QImageViewer | image viewer for Qt - Qt version & gt | Computer Vision library

I created a QLabel and set it's movie to a QMovie object with an animated gif. Then in the resizeEvent of my app I resize and move the label, so that it is centered/fit to the layout. This works fine but the movie has a lot of fine lines which get totally garbled in the resize operation, it seems there is no anti-aliasing. So either I am using the wrong resize method, or I need to set anti-aliasing somewhere right? There is nothing in the QMovie or QLabel documentation to suggest how to do this. I did read that the QMovie is inherited from a QImageReader, though that too has no property for anti-aliasing that I could find.

EDIT

I did somewhat get this to work, but it's still not quite right. I found that QMovie has a setScaledSize method which actually scales the underlying QImageViewer. Then I just have the label adjust to it's contents, namely the movie. Using the following code I am able to resize the movie with proper anti-aliasing, however it is quite "jumpy" and "flickery" during resize so obviously I'm not doing this quite "right". Also it somehow loses it's aspect ratio sometimes. Still looking for the correct way to do this... Maybe a QLabel is the wrong way to go?

Here's a working example
