Env:

python-barcode v0.13.1
python 3.8.10

Whenever I try to store a picture without the default SVG writer, tjis error shows up

>>> iw = ImageWriter(format="PNG")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not callable

After looking at the code, there is an IF statement that prevent the class declaration in barcode/writer.py at line 330.

if Image is None:
    ImageWriter = None
else:

    class ImageWriter(BaseWriter):  # type: ignore
        format: str
        mode: str
        dpi: int
        ...

nvm, should had checked the head of the file. Everything is fixed when I installed PIL.

It would be nice to include PIL as a package requirement.
