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.It can be used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the probability 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.

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.

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)

  • file_compression(filename) : It is used to read data from a file, and create a compressed file wit extention of ".rav"

  • 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")
  • 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.
  • 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")
