How did Wirephoto (news wire photo transmission) work ca. 1948 or earlier? Transmission over phone lines of...pixels? Was there error correction? Etc.

Just finished watching Northside 777 and was shocked not only by the early example of an "ENHANCE PHOTO" sequence but by the fact that a newswire photo service existed.
I looked up wirephoto @ Wikipedia but frustratingly there's no information about how the technology worked back then.
Any information would be appreciated. Just wondering how it was different from the dialup modem transmission system I used in the 1980s.
