PilImage returns wrong value for width

[tomsoftware]

Using:

        qr=qrcode.QRCode(
            version=1,
            error_correction=qrcode.constants.ERROR_CORRECT_L,
            box_size=4,
            border=3,
        )
        qr.add_data("Hallo")
        qr.make(fit=True)
        img = qr.make_image(fill_color="black", back_color="white", image_factory=PilImage)

        print(type(img))
        print(img.size, img.width, img.height)

prints:

<class 'qrcode.image.pil.PilImage'>
(108, 108) 21 108

So size[0] != width

I think the problem is that width and height are getter-functions https://github.com/python-pillow/Pillow/blob/d1731b35fed4e69158d98bffbf5a415f3a4cec8d/src/PIL/Image.py#L494

@property
    def width(self):

and something went wrong when calling them by getattr(self._img, name) https://github.com/lincolnloop/python-qrcode/blob/b80fea6ee7e75f3024b9ed7adf891a143e0b14e3/qrcode/image/pil.py#L53

I also ran into this issue just now. img.width is returning the QR code dot width instead of the image pixels width. The issue is not with Pillow but instead that qrcode uses width in BaseImage: https://github.com/lincolnloop/python-qrcode/blob/b80fea6ee7e75f3024b9ed7adf891a143e0b14e3/qrcode/image/base.py#L24-L31 And since the PilImage is subclassing BaseImage, it will get that width. As you also can se above, the actual image object is located under self._img. So getting the width direectly from that works: img._img.width
