What's TWAIN?

TWAIN is an open, industry-standard interface that directly
acquires image data from devices such as scanners and
digital cameras, without closing the application software.

The Elements of TWAIN

TWAIN defines a standard software protocol and API
(application programming interface) for communication
between the application software and the image-acquisition
device (the source of the data).
The three key elements of TWAIN are:
•The application software _The application must be
modified to use TWAIN.
•The Source Manager software _This software manages
the communication between the application software and
the source.The source code is provided in the TWAIN
Developer's Toolkit.
•The Source software _This software controls the image-
acquisition device and is programmed by the device
developer to comply with TWAIN specifications.
