##################################################################### Ravdec- LossLess Data Compression Algorithm Designer, and Module Developer: Mr. Ravin Kumar Email : mr.ravin_kumar@hotmail.com Github : github.com/mr-ravin/ravdec linkedin : https://in.linkedin.com/in/ravinkumar21 ##################################################################### Ravdec is a module written in python, which is based on a Lossless Data Compression Algorithm designed by Mr.Ravin Kumar on 19 September, 2016.This compression algorithm have a fixed compression ratio of 1.1429 in all possible cases, It accepts data of following format: alphabets,numbers, and symbols. Example: It can compress 1 GB to 896 MB. =======Application of Ravdec ========= It can be used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the propability of a symbol, as data keeps on getting large, and is transmitted over the network with a much faster rate. In this case also, the above module, and algorithm gives the same compression ratio. =======Application of Ravdec ========= NOTE- The data that is to be compressed should have length of multiple of 8.(i.e 8 elements, or 16 elemnts or 24...so on) 1) file_compression(filename) : It is used to read data from a file, and create a compressed file wit extention of ".rav" 2) file_decompression(filename) It is used to read data from a previously compressed file, and create a decompressed file wit extention of ".dec" Example: ------------------------------ import ravdec # to compress the file have elements of multiple of 8. ravdec.file_compression("filename.txt") # to decompress the previously compressed file. ravdec.file_decompression("filename.rav") ------------------------------ 3) net_compression("data to be compressed of length of multiple of 8 ") - To compress the original data to transmit, that is needed to be transmitted. 4) net_decompression(" previously compressed data") - To decompress the previously compressed data, that is received. It is used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the propability of a symbol, as data keeps on getting large, and is transmitted over the network with a much faster rate. Example: ------------------------------ import ravdec # for compression compressed_data=ravdec.net_compression("ASDFGHJK") # note- data to be compressed should have length of multiple of 8.(i.e 8 elements, or 16 elemnts or 24...so on) # for decompression decompressed_data=ravdec.decompression("previously compressed data") ------------------------------ This module is a freeware, build with the intention to help communities in data compression aspects. ->Application of this module: It can be used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the propability of a symbol, as data keeps on getting large, and is transmitted over the network with a much faster rate.
