Webcam scanning support
Since scanners are often so slow and not portable (for scanning receipts on the go), it would be amazing if GNOME Scan could support not only USB scanners, but also webcam/camera devices, whether on computers (built-in or USB) or smartphones that can run a proper "desktop Linux" (such as the L5, to name only one).
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 (issue #56 I think?)
- Ability to finely adjust the cropping/shape with handles in each corner and on each segment of the rectangle
- Automatic image colors balance and levelling/processing (including an option to force grayscale; issue #34 and #17)
As well as:
- Ability to add more pages one by one (like GNOME Scan does)
- Automatic OCR (GNOME Scan issue #1)
- Ability to clean up some areas with an eraser brush / healing/clone brush (OK, that one is certainly far from trivial, so I'm not expecting that from GNOME Scan just yet :)
- Ability to share the result directly via email or other apps (such as the NextCloud app), though that's inferior than GNOME Scan's ability to save directly to disk as files instead of depending on some cloud hoops jumping
