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.
