Project description

Pycasso

Downloads Latest PyPI release Latest Github release License Build Deploy

Split image into tiles and scramble/unscramble them based on a seed. The demo application can be found at https://image-scramble.herokuapp.com.


Scramble

Using scramble mode on this sample image will produce the following output:

example_scramble

Unscramble

To revert the image to its original state, use the same seed and slice_size on unscramble mode.

Setup

Install from PyPI

$ pip install image-scramble

Install from source

  • First, you should get a copy of this project in your local machine by either downloading the zip file or cloning the repository. git clone https://github.com/catsital/pycasso.git
  • cd into pycasso directory.
  • Run python setup.py install to install package.

Usage

Web application

  • Run python app/app.py

Docker

  • Build from local using:
$ docker build -t "image-scramble" .
$ docker --name pycasso -p 5000:5000 -d image-scramble
$ docker pull catsital/image-scramble

Command-line utility

$ pycasso image_input.png image_output scramble

This will produce a scrambled image with seed based on your current system time. Hence, the output will be completely unpredictable and irreversible. Use the options -n for slice_size, -f for format, and -s for seed, like so:

$ pycasso image_input.png image_output scramble -n 50 50 -s seed -f jpeg

Script

Initialize a Canvas and use scramble on export by:

from pycasso import Canvas
Canvas('image_input.png', (30, 30), 'seed').export('scramble', 'image_output', 'jpeg')
