Bonus geometry types in GeoJSON

Basically two types:

1. Rectangles
2. Circles

Let's say you have a drawing tool that permits both. Both geometry types benefit from some non-standard drawing abilities: it would be nice to resize circles, and it would be nice to resize rectangles in a way that keeps them rectangular. However, GeoJSON does not have circle or rectangle types. Both are represented as polygons. This gives us two options:

1. "Detect" these shapes with a heuristic. This is doable for a rectangle by checking the corners, but much, much less doable for circles. Also, circles have an additional property that I will mention in the next bit.

Google Lens For Ubuntu

For those who use Google Lens on Android as an OCR to capture text from images, screenshots, etc.. here is a bash script that does the same on Ubuntu.

Sometimes we need to copy a telephone number in an APP where there isn't a copy to clipboard feature enabled or maybe to copy texts from an picture.

This can be done with a OCR, this script does that allowing to drag&drop select a region of the screen and copy to clipboard the text parsed from the image.
