Webcam scanning support
Basically the same idea as in GNOME/simple-scan#344 ;)
Since scanners are often so slow and not portable (for scanning receipts on the go), it would be amazing if Paperwork could support not only traditional scanners, but also webcam/camera devices, whether on computers (built-in or USB) or smartphones that can run a proper "desktop Linux".
The idea is to have an alternative to Adobe Scan, which has the following killer features:
- Automatic shape recognition, to crop and shape those receipts photographed in imperfect conditions
- Ability to finely adjust the cropping/shape with handles in each corner and on each segment of the rectangle, whether via the mouse cursor and/or touchscreen
- Automatic image colors balance and levelling/processing (including an option to force grayscale)
As well as:
- Ability to photograph and add more pages one by one
- Automatic OCR (which you already have!)
- Ability to clean up some areas with an eraser brush / healing/clone brush
