Specify only the\n                        file name, or use .png extension; png extension will\n                        be added automatically\n\n```\n\n## Example\n\nWe could encode a simple txt file like `file.txt`:\n```\nThis script is working!!!\n```\n\nRunning the script like:\n```\n$ python3 Image_Steganography.py -e -i resources/original.png -f resources/file.txt -o resources/encoded.png\n```\n\nThe result is an encoded image which looks identical to the original:\n\n![Original](resources/original.png) | ![Encoded](resources/encoded.png)\n|:---:|:---:|\n| Original | Encoded |\n\nFrom the encoded image we can extract the concealed file:\n```\n$ python3 Image_Steganography.py -d -i resources/encoded.png -f resources/file_concealed.txt\n```\n\n## Requirements\n| Software       | Version        | Required |\n| -------------- |:--------------:| --------:|\n| **Python**     | Either 2 or 3  |    Yes   |\n| **Numpy**      |Tested on v1.13 |    Yes   |\n| **Pillow**     |Tested on v4.3.0|    Yes   |\n| **imageio**    |Tested on v2.2.0|    Yes   |\n\n## Future developements\nMaybe implement a GUI.\n\n## License\nLicensed under the term of [MIT License](http://en.wikipedia.org/wiki/MIT_License).
