Scaled QPixmap looks bad

I have the following widget:

pixmap = QtGui.QPixmap(r'pics\cdaudio.png').scaled(100, 100)

The image is scaled down, from 256x256. It looks pretty choppy:

How can I scale it smoothly from within Qt?

Solution

  • Use the transformMode parameter:

    pixmap = QtGui.QPixmap(r'pics\cdaudio.png').scaled(100, 100, transformMode=QtCore.Qt.SmoothTransformation)
