Scanning+Cropping documents cuts off the bottom part

[ThePurox]

Hi, I really enjoy using your app. I found the following bug:
When scanning a document and then cropping the image to the document, the bottom part of the document is cut off.
Below you find screenshots that show the process with a ruler instead of a document.
Taking the image and selecting the region to crop:

Which results in this crop, where the bottom 1.5cm are missing:

Also when the image is rotated the part is missing:

This then finally results in the following document in paperless:

I'm using the current version in F-Droid (0.0.11) on LineageOS 17.1 (Android 10) on a OnePlus2.

Best Regards
Purox

Thanks for reporting this.

I can reproduce the bug on my device. Let's see if I can find the cause.

It seems that the bug is caused upstream of your fork of edge_detection.
It got fixed ~2 weeks ago. See this Issue
Maybe merging this pull-request into your fork, might also fix the bug in paperless.
