PyQt:How do I display a image properly?

Question

I want to display an image in pyqt so,i used a label and the pixmap option,and the scaledContents but the image is distorted.Should I use another widget or do something else? Thanks.

This is the code:

from PyQt4 import QtCore, QtGui
self.label.setPixmap(QtGui.QPixmap(_fromUtf8('image.jpg')))
self.label.setScaledContents(True)

I use QtDesigner.

I tried this: self.label.pixmap().scaled(QtCore.QSize(self.label.size()), QtCore.Qt.KeepAspectRatio, QtCore.Qt.FastTransformation)

but the images don't get resized to fit the label.

Use the scaled(const QSize, Qt::AspectRatioMode, Qt::TransformationMode) method of the pixmap, it has an option Qt::KeepAspectRatio that does not deform the image. The default is to ignore the aspect ratio

Also, note that the scaled method returns the scaled pixmap, so it must be used this way:

myPixmap = QtGui.QPixmap(_fromUtf8('image.jpg'))
myScaledPixmap = myPixmap.scaled(self.label.size(), Qt.KeepAspectRatio)
self.label.setPixmap(myScaledPixmap)
