carlosm00/metapy

Pythonic service to read and remove images metadata.

MetaPy

Simple pythonic CLI application for image metadata collection and (optionally) delete it. Run on Windows and Unix-based OS.

Required libraries

• Pillow (PIL fork)

Features

• Open Source
• Python-based, full CLI application
• Logging on:
  • User level (info)
  • Developer level (debug, error)
• Force option

How to use

Clone repository

git clone https://github.com/carlosm00/MetaPy.git

Run CLI application

Run through terminal providing absolute route file or source.

python metapy.py C:\example\folder

After reading the metadata of the file, you will be asked if you wish to create a copy of the image without metadata. The script will only accept a 'yes' (lowercase), otherwise, it ill consider you don't want the copy. There is a way to force the copy without being asked by using the '-f' after the path:

python metapy.py C:\example\folder -f

Please, note that more than three (3) arguments will be considered a wrong use of the script.

Tests and 'Source' folder

For testing purposes, we created a 'Source' folder containing the following files:

File	Type	Description	Test result
full_negative	png	Corrupted file	Error: Invalid file
positive_no_meta	jpg	Plain image without metadata	Only size and mode
full_positive	jpg	Phone-taken camera	Full metadata output and duplication without metadata

Extra notes

Why Pillow?

Pillow as the successor of PIL offers faster data-accessing methods and powerful optimized processing capabilities, with a continued contribution as a live project. Reference:

Logging

For logging capabilities, we use the built-in 'Logging' facility. Reference and documentation:

- https://docs.python.org/3/library/logging.html

imghdr for image validator

The imghdr builtin module is not used as it gets deprecated on 3.11. Opening the window for future versions. Reference:
