Well, I should read the documentation more clearly before making statements
like this. There is a case where the depth does "sort of" imply a data
transmission format from a depth value. In the case where the depth == 1
with value data (ie Lineart scans) SANE declares that this should be a
packed data format with 8 pixels per byte. This exception makes a lot of
sense (it seems to be the natural trasmission format for Lineart scans)
but it *is* an exception. So the general rule still stands.
