2009.04.26 17:22 "[Tiff] Packbits worst case encoded length", by Simon Berger

I implemented the packbits encode/decode functions of libtiff. It works great overall, but sometimes the worst case formula:

srcByteLen + (srcByteLen + 126) / 127

doesn't work. On a 24 bit image with big width I got 1 - 15 higher output. Is this due to a non standard implementation and is there any length I can safely use instead of any flushing inside the function (I cut the block off)?

Thanks in advance.
