Hi, In the last weeks there have been some improvements to the SnapScan backend for 2480/2580. Most of them were contributed by Simon Munton, who deserves all the credit :-) In particular there is now support for 16 bit/color scans for the 2480/2580.
The backend also distinguishes now between the 2480 and the 2580 and sets the boundaries for transparency scanning accordingly. This part needs some broad testing since the distinction is not documented anywhere. I also hope to have fixed the preview issue for the 2580. To test, please compile and install the latest SANE backends from CVS (but make sure that you don't install two version of SANE at the same time, see the README file that comes with the SANE sources). After starting xsane and selecting the transparency unit as source the boundaries of the preview window should change automatically to 5.5 cm x 12.5 cm for the 2480 and to 5.5 cm x 8.0 cm for the 2580. IMPORTANT: If the boundaries are not changed correctly don't attempt to scan, not even for previewing. Instead, please send me an email with the debug log from "SANE_DEBUG_SNAPSCAN=50 scanimage --help 2>debug.log" If the preview area changes correctly everything should work fine :-) The sources are available from the daily CVS snapshot at http://www.sane-project.org/snapshots/ Regards, Oliver
