name 'height' is not defined

❯ python converter.py --to-macpaint ~/Desktop/input.png ~/Desktop/output.mac
Traceback (most recent call last):

    macpaint_file = png.convert()
                    ^^^^^^^^^^^^^

                                     ^^^^^^
NameError: name 'height' is not defined

If I change it to self.height I get a new error:

  File "/Users/rockwell/Projects/macpaint_file/macpaint.py", line 173, in _gen_packed_data
    assert len(bit_line) == cls.WIDTH / 8, f"error in condensing bytes into bits; line is only {len(bit_line)} bytes"
AssertionError: error in condensing bytes into bits; line is only 128 bytes

Here is the input PNG:

Any help would be appreciated, thank you.

Figured it out... there was a math error when calculating how much padding to add. Fixed in #4.
