How to disable anti-aliasing in QMovie(or QLabel)?-CodePudding

I want to use QMovie in QLabel to show a pixel animation but anti-aliasing seems to be enabled by default. This makes the pixel painting not look like a pixel painting.

QMovie* movie = new QMovie(":/gif/exp.gif");
movie->setScaledSize(QSize(200,200));
label->setMovie(movie);

CodePudding user response：

QMovie just play your gif inside label, It didn't change anti-aliasing, If you didn't see that gif with the high quality you should change that gif.

The QMovie class is a convenience class for playing movies with QImageReader.

this means that it didn't use paint.

one thing that makes you see that gif in low quality is for change scale movie->setScaledSize(QSize(200,200));

If you remove this you can see what your gif is actually, with that original quality.
