How to integrate document scanning into a Qt application?

What are some resources about learning how to integrate docume开发者_运维技巧nt scanning into a Qt application?

I'm somewhat familiar with TWAIN drivers to interface with a scanner, but is this technology cross-platform or specific only to Windows?

You could check these project samples: https://github.com/twain/twain-samples http://sourceforge.net/projects/twain-samples/ which are Qt based. The readme says:

TWAIN Application

This is a TWAIN version 2.1 of the specification compliant application.
It offers text based interface. It shows how to implement many of the operations needed by an application.

You will need to have the FreeImage installed on your system for this application to work properly.
