Hi, I have an LZW compressor/decompressor written in C. The initial table consists of ASCII characters and then each now string to be saved into the table consists of a prefix and a character both saved in a list as int. My compression works but my decompression leaves some characters out. The input: <title>Agile</title><body><h1>Agi...
I have a database which contains picture data stored as a binary blob. The documentation says the data is encoded using LZW. I thought that I could decode it using the Zip or GZip input streams found in the Java library, but it didn't work - I got an exception that said the format of the data is not correct. From what I've read, the lib...
Is there any code that I can look at to see how compression would be done in assembly? ...
I was trying to create a lzw compression program. But i need to finish it by today itself so i want to use some dll for taking my input as txt file and output to as a text file. I want to do this in TURBO C++ code which are doing my remaining functionalities. Can anyone suggest me some method. ...
HI All, I have below code to extract a single page from a multi-paged TIFF file. The problem is, the input file is in CCITT Group 4 compression however the output compression is LZW. Can .NET outputs TIFF files other than this compression? FileStream fileStream = File.Open(outputFileName, FileMode.Create, FileAccess.ReadWrite); sou...
Can anybody give pointers how I can implement lzw compression/decompression in low memory conditions (< 2k). is that possible? ...

PyLZJB LINK The library is a binding for a C library, the file is located here PyLZJB.so Unfortunately by copying to the site-packages directory when import I get the "Wrong ELF class" error. >>> import PyLZJB Traceback (most recent call last): File "<stdin>", li...
I need to learn how to do Lempel–Ziv–Welch compression using pen and paper for my algorithms and data structures class. Unfortunately we have only a couple of examples in our book of how it is done. I'd like to practice compressing and decompressing text using it, but I need to find a way to check if I'm right doing it right or wrong. On...
