I started to write a little program that allow to compress a single file using LZ77 compression algorithm. It works fine. Now I'm thinking how to stor ...
https://github.com/sgherro/Exercises-cpp/blob/89bbd78eeac9666ed20f083ebf116e693a8c23ce/Lempel-Ziv-Stac/main.cpp I am using this algorithm to decompres ...
In the LZ77 phase of the DEFLATE compression, extra bits are used to represent the length and distances of the back reference. However, are these extr ...
I'm trying to learn LZ77 algorithm with my friend, and some case give us a confusion. for example) init search buffer size: 7 look-ahead buffe ...
I am trying to understand the deflate algorithm, and I have read up on Huffman codes as well as LZ77 compression. I was toying around with compression ...
I am trying to put together an app in python that will split a .prn file generated from Zebra Designer software containing thousands of labels in one ...
when i insert a grayscale image then the algorithm works if i insert a rgb image the output is wrong. is the way I work with the rgb image correct? I ...
I'm writing simple compression program using LZ77 algorithm. My problem is very slow compression speed on any big files (for 2 MB image it takes more ...
I have huffman and lz77 codes, but I need any way to merge this algorithms to make deflate How i can do this? I have to write it manually without us ...
Is bit packing detrimental to the performance of gzip? Assume that I have 7 bit values and pack in the following way: As far as I understand LZ com ...
Can someone please explain the difference between the LZSS and the LZ77 algorithm. I've been looking online for a couple of hours but I couldn't find ...
I'm trying to decode a string which is encoded using LZX algorithm with a LZX window size of 2 megabytes (binary) and then converted to base64. I'm r ...
I'm coding LZ77 compression algorithm, and I have trouble storing unsigned chars in a string. To compress any file, I use its binary representation an ...
I'm trying to find a correct implementation of LZ77, the original famous algorithm in the 1977 paper. What I have found is a number of different imple ...
I'm working on breaking down ZPL label definitions generated by NiceLabel label making software. For the most part I don't have to worry about decodin ...
I'm doing a reverse engineering in a Gameboy Advance's game, and I noticed that the originals developers wrote a code that has two system calls to unc ...
I want to compress .txt files that contains dates in yyyy-mm-dd hh:mm:ss format and english words that sometimes tend to be repeated in different line ...
I wrote a Java compressor for a super obscure compression format. (It was mainly used on Amiga Computers in the 1990s). There is a fair amount of doc ...
I am making my own DEFLATE compressor, which already beats ZLIB library almost every time. In DEFLATE format (LZ77), the data stream either contains ...
I read about gzip compression and png image compression and they both use DEFLATE alghorithm, but I'm not sure that the implementation of that algorit ...
