[13:06:08] <zebr> Hi, I've found that, whereas the docs say that Image.frombytes takes unpacked pixel data, in the case of mode='1', it's actually expecting packed data with 32-bit aligned rows, as if it were 1-bit-depth BMP data. When you Image.getdata, it is unpacked. Is this intended?
[13:22:28] <zebr> My mistake, it's just 8-bit aligned, so each row starts on a new byte.
[13:24:12] <zebr> This is with Pillow 6.1. If this isn't what's expected (as suggested by the docs), I can open a bug ticket.
