Auto Cropper

A small snippet that crops screenshots from social media platforms like Instagram to only contain the picture. This is done by looking for the first row / column on the top / bottom / top / left of the screen (Starting from the center) where all pixels are the same color. This -usually- marks the end of a picture.

This tool is NOT perfect and compression algorithms like JPEG might mess up the working of this tool. It's more of a "Best guess" method.

1. Install "PIL" for Python: python -m pip install Pillow

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
