Image cropper (and colorizer) for pdf scans

Image cropper for personal use (might not work with your pdfs)

Requires pdfimages on the path to work properly It's thought just for my workflow so is error prone at the moment.

Example usage with the provided sample pdf

This will open the image cropper window for the single page the pdf has, after that you can create crop rectangles with right click and change their color by left clicking those rectangles, to save the crops just close the window
