How to decide/determine # of bits?

[brandonmp]

Im not familiar w/ image or file handling, so the language about the bits param in the docs is unclear to me. Can someone elaborate on what is meant by "number of bits in a row"?

After reading a little bit about perceptual hashing, my guess would be it's the number of bits of the output (hash) you want to get. But it's just a guess. Better docs are really needed here.
