I have a few more specifics on this that might be of some value to developers.
Would be curious to know if any of this holds true for running under Linux.
I am able to utilize xscanimage without any core dumps. I can preview in full
color. Unfortunately it's nearly unusable due to it being nearly 2 inches
off target in the preview scan. In other words, whatever area I hi-lite to
do a full scan, I get an area about 2 inches below that.
XSane I've managed to work around to sort of usable. If I do a half-tone
preview I can then do a full scan in color. Unlike xscanimage, the selected
area appears to be right on target. It's really hokey, but it's workable I
Lastly, of course, the core dumps in XSane if one attempts to do a full color
or gray scale preview.
Are all these items specific to FreeBSD alone for this scanner? Should I be
passing this information along to the uscanner developers? Is there anything
else I should be looking to collect in the way of info?
