Hi there,

We don't provide this kind of option in our toolkit and I don't know any company which do that.

However, I can give you some hints:

- This kind of application is also called a Twain Data Source (Twain DS)
- The team provides an example of TWAIN DS written in C which is quite comprehensive. You can download it from

I think a good way is to learn a bit the open source application provided by team & modify it to do your own TWAIN virtual driver. Not so hard task but requires some time & investigations. Also, you can have more information on this kind of application browsing the forum located at

With best regards,
