I have just found a nice document scanning app for android that can do automatic edge detection, cropping, multipage scanning, OCR, PDF export and more.
It's called #makeacopy and it's using #tesseract engine to perform the OCR directly on the device with no internet connectivity requirement at all.
The app has almost full #a11y support for screen reader users in the sense that all the controls are clearly labelled and it's easy to navigate.
I can't resist and I have asked the developer if it would be doable to add a screen reader compatible notifications making the automatic edge detection somehow accessible as well.
Now I'd appreciate comments from low vision screen reader users, mobility trainers, people assisting other blind people or others who might be able to tell if my idea is viable and how much you like it?
Here is link to the github issue I have started: github.com/egdels/makeacopy/is…

Thanks for looking into it.
