Hi all,
To get my new Canon Lide 210 working I compiled sane-backends-1.0.22
from the sources.
At the end of the scan (with xsane 0.997 on Debian Squeeze) the scanner
bumbs into a hard stop. The following patch fixes this:

Two remarks on the numbers:
The excact reference corner is (with my scanner) at x = 1.7 and y = 7.7.
The sum of x-corner and x-width must not exceed 218.9, otherwise the
scanned picture gets garbled due to too less pixels per line retured.
One peculiarity observed. As soon as enhancement options are enabled in
xsane (like software deskew or software crop in the extended options
window) the scanner stops at the bottom and does not return to the start
position. Well, with the next scan, it first returns to the start
position. Any ideas on that?
Did anybody find out how to make e.g. "A4" the default size in the xsane
preview pane? But maybe my xsane is simply too old (0.997).
Best regards,
Peter
