Can i use QtGui.QImage(filename) insteadof PIL.Image.open(filename) in load_image_file(Class LabelFile)?

[David-dotcom666]

I would like to ask why QtGui.QImage(filename) is not suitable to replace PIL.Image.open(filename)... . In my project, my image is a 2000W pix color BMP image, which is slower using the original method, but I use QtGui.QImage (filename) to read it much faster. May I ask if it is possible to do so? Or is this related to any potential issues
