Re: [ajug-members]: controlling a scanner from Java

[Angus Berry <angus.berry@elken.com>]

John,

When OS drivers are necessary for hardware, to me, that is the point
where you're getting tied to the OS. That being said Windows almost
universally abstracts Scanners (and some digital cameras) to the TWAIN
interface. 

Therefore you're going to need a Java TWAIN library (hope I'm not
preaching to the choir too much here). Here's a link to an article on
interfacing Java to TWAIN and Google will find you the rest of what you
need.

I haven't done this in pure Java, but have had great success with the
Win32 Libraries from LeadTools:

The beauty of TWAIN is that you're client won't be tied to a specific
scanner and you'll be the hero :-) unless the say cool let's run it on
Linux too :-0
