Here is the relevant section from the TIFF 6.0 spec. Note that the runs DO break at the end of a line. You do NOT compress across lines as if the strip is one homogenous buffer. [...] [...] Here are some additional rules:
. Pack each row separately. Do not compress across row boundaries.
[...] When PackBits data is decompressed, the result should be interpreted as per compression type 1 (no compression).
