FAQ on TWAIN Specification

All you wanted to know about TWAIN specifications – in a simple Question-Answer format…

Q.  What is the TWAIN specification?

A. TWAIN (Tool Without An Interesting Name) is an industry-standard, open specification that defines the way in which an image acquisition device (typically a scanner) communicates with an application program. With TWAIN, an application program can acquire images through any device that complies with its specifications. 

Q. Which software/devices are TWAIN-compliant? 

A. TWAIN-compliant software/devices are those which follow the basic TWAIN requirements. 

Q. Is it necessary for an image acquisition software/device to be TWAIN-compliant? 

A. No, it is not at all necessary for an image acquisition software/device to be TWAIN-compliant, but it is RECOMMENDED as almost all image acquisition hardware and software follow the TWAIN specifications today.

If an image acquisition software/device does not follow this standard you would have to scan an image with one application, save it and import the image into another application.

But, if the image acquisition software/device is TWAIN compliant then the software can call up the scanner’s user interface without importing or opening other programs. 

Q. Where can I get more information on the TWAIN specification? 

A. You can get more information on the TWAIN specification at www.twain.org
