Class BitUnpacker

initial_code_size is the starting size of the codebook associated with the to-be-unpacked stream.

Overrides: object.__init__

Given an iterator of bytes, returns an iterator of integer code points. Auto-magically adjusts point width when it sees an almost-overflow in the input stream, or an LZW CLEAR_CODE or END_OF_INFO_CODE

Trailing bits at the end of the given iterator, after the last codepoint, will be dropped on the floor.

At the end of the iteration, or when an END_OF_INFO_CODE seen the unpacker will ignore the bits after the code until it reaches the next aligned byte. END_OF_INFO_CODE will *not* stop the generator, just reset the alignment and the width

>>> import lzw
>>> unpk = lzw.BitUnpacker(initial_code_size=258)
>>> [ i for i in unpk.unpack([ chr(0), chr(0xC0), chr(0x40) ]) ]
[1, 257]
