> I think your formula was correct, for a best-effort compressor.

Those answers really aren't helpful.

1) I know that it has to be correct because it is from the specification of the packbits algorithm
2) I pointed out that I need to get a presumption of the libtiff implementation of packbits.

The reason for point 2 is a lossless re-compression of Tiff files I do. You can read it here:
