Topic: pdf with LZW decode
Conf: (P-PDF) Beginners, Msg: 163987

I am trying to extract text from pdf which has filter parameter set to LZWDecode without any sort of encryption . I have read the LZW algorithm and i think the core implementation is different from the one that is used in pdf . Cause my implementation is done in php and its losing some part of the actual output after decoding . Can any one point me to any link which can describe how the LZW encoding is done in case of pdf documents? Thanks in advance.
