Introduction

Since I don’t have a scanner at home, if I need to quickly share a soft copy of a physical document online, usually I take a picture of the document from my mobile phone and share. But the problem with pictures is that the sides of the document do not appear parallel in the image. I used to use Google Photos to crop an image to the edges of the document so that it appears somewhat like a scanned document and not an obvious crappy picture taken from a mobile phone camera.
