Rotation of a QImage by 90 degrees

[Uday More]

I have a QImage(32*128) as shown below.

I want to rotate it by 90 degrees which may look like this

Is there a simple function to rotate the QImage.

Also will the resolution change, when we rotate the image.

@Uday-More said in Rotation of a QImage by 90 degrees:

I would say QImage::transformed() should do the job:

QImage img("src.jpg");
QImage rotatedImg = img.transformed(QMatrix().rotate(90.0));
rotatedImg.save("rotated.jpg");

@KroMignon . Thanks
It works with transform function
