PNG generated from CLI is corrupt

[mikepianka]

I'm finding that the PNG generated from the command line tool is corrupt, but the PNG generated from Python is fine. I'm using version 6.1 on Windows.

This creates a corrupt PNG that Windows Photo Viewer, Paint.NET, IrfanView, etc. can't open: qr "Some text" > test.png

This PNG is fine:

import qrcode
img = qrcode.make('Some data here')
img.save('test2.png')

I found an old closed Issue #92 that seems like it may have been a similar problem?

I cannot confirm the problem, using qrcode 6.1 (six 1.15.0, colorama 0.4.4) and Pillow 8.1.0 with Python 3.9.1 seem to deliver the correct output.

It generates a PNG file about 1kB which is readable by the Windows Photo Viewer.

Here's the corrupt output:

I tried it with Python 3.8.7 and I get still a valid image (Windows 10.0.18363)

Sorry for not being able to help.

I didn't come to a conclusion and just ended up running the tool through python for my purposes.
