AttributeError: type object 'QPixmap' has no attribute 'formImage'

The error message suggests that you are calling the 'formImage' method on the QPixmap class, but that method does not exist.

There is no 'formImage' method in the QPixmap class. Perhaps you meant to call 'toImage' instead, which returns a QImage object representing the pixmap.

Here's an example:

from PyQt5.QtGui import QPixmap

# create a pixmap
pixmap = QPixmap('image.jpg')

# convert the pixmap to a QImage
image = pixmap.toImage()

This will create a QPixmap object from the image file 'image.jpg', and then convert it to a QImage using the 'toImage' method.
