@Pl45m4 Thank you.
Documentation for Python : https://doc.qt.io/qtforpython-5/PySide2/QtGui/QPixmap.html

Example of code :
I give this because of the minimum examples on the internet

from PyQt6.QtCore import Qt
...
self.labelCropFace.setPixmap(pixmap3.scaled(self.labelCropFace.size(), Qt.AspectRatioMode.KeepAspectRatio))

For other people who need it, hopefully it helps too
