[Feature Request] Add Document Scanner to "Take Camera Picture"

[abdeldjalil-fellah]

Currently, the "Take Camera Picture" option captures a normal photo without any document-specific enhancements. It would be very useful to include a built-in document scanner mode in this feature.

The document scanner should provide capabilities such as:

• Automatic document edge detection
• Perspective correction (flattening the page)
• Auto-cropping and alignment
• Improved contrast and readability (black & white / enhanced mode)
• Multi-page scanning support (optional)

This would greatly improve the quality of captured documents and make the camera feature more suitable for scanning receipts, invoices, forms, and other paper documents directly within the app.

The "Take Camera Picture" just delegates to whatever camera app is installed on the device. The app itself doesn't interact with the camera. So it's up to the camera app whether it offers a document scanner functionality. You might be able to find and install such an app.

I do not want to add such a feature directly into the app, mainly because it would require the app to make use of the Camera permission, which would justifiably be a privacy and data protection concern for many users.
