Hi,
|
|
<BR>
|
|
<P> I'm a little puzzled; I'm trying to scan some light-gray text on white
|
|
<BR>
|
|
paper. I can accomplish a particular scan settings with gimp plugin, but
|
|
<BR>
|
|
not with "scanimage" frontend :
|
|
<BR>
|
|
<P> ps auxwww | grep scan
|
|
<BR>
|
|
<P>... /usr/lib/gimp/1.0/plug-ins/xscanimage -gimp 11 9 64 64
|
|
<BR>
|
|
<P> here I have set the gimp's dialog box to :
|
|
<BR>
|
|
<P>resolution 300
|
|
<BR>
|
|
scan speed 1
|
|
<BR>
|
|
exposure -18
|
|
<BR>
|
|
brightness -100
|
|
<BR>
|
|
contrast 49
|
|
<BR>
|
|
white level 255
|
|
<BR>
|
|
black level 180
|
|
<BR>
|
|
midtone 183
|
|
<BR>
|
|
no gamma
|
|
<BR>
|
|
... dimensions ...
|
|
<BR>
|
|
<P> with the above through gimp plugin, things work, I get pretty good
|
|
<BR>
|
|
results,
|
|
<BR>
|
|
<P>but when I try to use command line settings, it doesn't seem to help
|
|
<BR>
|
|
any. This command :
|
|
<BR>
|
|
<P>scanimage -d net:fred:microtek:/dev/scanner -v --exposure -18 --mode LineArt --resolution 300 -l 0in -t 0in -x 3.49in -y 02.00in --brightness -98 --contrast 48 --white-level 255 --black-level 180 --midtone 183
|
|
<BR>
|
|
<P> has only little better visual results than this command :
|
|
<BR>
|
|
<P>scanimage -d net:fred:microtek:/dev/scanner -v --exposure -18 --mode LineArt --resolution 300 -l 0in -t 0in -x 3.49in -y 02.00in
|
|
<BR>
|
|
<P> both of them are ways away from the gimp plugin results.
|
|
<BR>
|
|
<P> What can be wrong ? It looks like the command line may be interpretted
|
|
<BR>
|
|
incorrectly / differently from the gimp's plugin. I.e. although given same
|
|
<BR>
|
|
user-supplied values, the scanimage frontend may be sending different data
|
|
<BR>
|
|
to the backend than the gimp plugin.
|
|
<BR>
|
|
<P> How can I find out what's wrong ? Is there a way to turn on debugging on
|
|
<BR>
|
|
saned to find out what params it's receiving from either of the frontends
|
|
<BR>
|
|
? I tried manually starting "/usr/sbin/in.saned -d128", but no useful
|
|
<BR>
|
|
debug was forthcoming. Even with "/usr/sbin/in.saned -d" I only got basic
|
|
<BR>
|
|
debug. (see below)
|
|
<BR>
|
|
<P><P> my setup :
