[FIXED] Resize images inside qt-label

Issue

I have a qt label which by default has a place holder image in it:

self.label.setPixmap(QtGui.QPixmap(_fromUtf8("place_holder.jpg")))

There is a function to update the image contained in the label which is:

def selectFile(self):
image = QtGui.QFileDialog.getOpenFileName(None, 'Select Reference Image', '', '*.jpg')
self.label.setPixmap(QtGui.QPixmap(_fromUtf8(image)))

This works fine (the image is updated), but it is also deformed if the image used to update the label has different size from the place holder image.

Is there any way to fix this? I mean to adapt the image and to keep fix the size of the label?

Solution

You can try to set the scaledContents property:

self.label.setScaledContents(True)
self.label.setPixmap(QPixmap("your_image.jpeg"))

It works fine for me.

Beware that this scale the image to fill all available space. It means that the aspect ratio of the image wont be preserved unless the label size and the image have the same aspect ratio. You will have the same problem using the QPixmap.scale method as you can see in the images here.
