Are there Virtual Twain Scanners? Sort like Daemon

问题:

I am testing a scanning application and currently I dont have any scanner to plug it in. Is there anyway to have a virtual scanner like Daemon Tools does with Virtual CD Drives?

回答1:

There's a Sourceforge project with a sample TWAIN implementation, including a virtual scanner. I haven't found anything similar for WIA.

回答2:

Yes, there is a pretty simple to use application called UniTwain. I am using it and it works really nice for my users. You can download it from http://www.terminalworks.com/unitwain

I would like to make people aware of GenDS

Download ZIP

According to this web page, GenDS

is a ready-to-build Microsoft C++ 6.0 project that compiles to a generic TWAIN Datasource (DS)

I am in the process of compiling it so I cannot give further advise.
