Convert all images in a specified directory to a specified file type (.png | .jpg).

• To specify the directory that has all the images you want to convert, change the INPUT_PATH variable in ./constants/constants.py. This can be anything, as long as it is a valid path 😄.
• To specify the directory that will contain all the converted images, change the OUTPUT_PATH variables in ./constants/constants.py. Again this can be anything, as long as it is a valid path 😄.
• To specify the output type of all the converted images, change the OUTPUT_FILE_TYPE variable in ./constants/constants.py. This can be any file type supported by the Wand pip library and the ImageMagick suite, which are detailed here:
  • Wand: https://docs.wand-py.org/en/0.4.5/guide/write.html
  • ImageMagick: https://imagemagick.org/index.php

• In your terminal, create a virtual environment (venv) through the following command. Remember to replace the venv's name:
  • python3 -m venv <NAME_OF_YOUR_VIRTUAL_ENVIRONMENT_HERE>
• Activate your virtual environment with the following command:
  • source <NAME_OF_YOUR_VIRTUAL_ENVIRONMENT_HERE>/bin/activate
• Once your venv is activated, install all the necessary pip packages detailed in requirements.txt. You can do this by using this command:
  • pip install -r requirements.txt
• Once this command succeeds, specify the necessary parameters in ./constants/constants.py as detailed above.
• Run the command below. This will start your image conversion!
  • python image_conversion.py

• This script uses python's multiprocessing library as a workaround to the GIL. This helps with scalability, given a case where you have hundreds of images (or more) that you want to convert from one file type to another. This gives a noticeable performance boost :)
• If you have any suggestions on how to make this script better, please add an issue here:
