This file implements a SANE backend for the Kodak DC-240
|
|
digital camera. THIS IS EXTREMELY ALPHA CODE! USE AT YOUR OWN RISK!!
|
|
|
|
(feedback to: dc240-devel@fales-lorenz.net)
|
|
|
|
This backend is based somewhat on the dc25 backend included in this
|
|
package by Peter Fales, and the dc210 backend by Brian J. Murrell
