Hi Andreas,
|
|
<BR>
|
|
<P>Here is some more debug information for you for my LS2000.
|
|
<BR>
|
|
This time I tried scanning the same image twice, once with Scan Mode
|
|
<BR>
|
|
set to color (see <A HREF="http://bfnet.com/misc/gimp-coolscan-debug-color.txt">http://bfnet.com/misc/gimp-coolscan-debug-color.txt</A>),
|
|
<BR>
|
|
and once with Scan Mode set to RGBI (see
|
|
<BR>
|
|
<A HREF="http://bfnet.com/misc/gimp-coolscan-debug-rgbi.txt">http://bfnet.com/misc/gimp-coolscan-debug-rgbi.txt</A>).
|
|
<BR>
|
|
<P>The Scan Mode of color seems to work allright, except for the fact
|
|
<BR>
|
|
that sometimes the scan turnes out very blue. The RGBI scan doesn't
|
|
<BR>
|
|
return a picture at all because of a frame error.
|
|
<BR>
|
|
<P>Andreas> Plase send me the debug output (unless it is more than 200kB,
|
|
<BR>
|
|
Andreas> in that case try scanning smaller images).
|
|
<BR>
|
|
<P>The debug output is in these two URLs:
|
|
<BR>
|
|
<A HREF="http://bfnet.com/misc/gimp-coolscan-debug-color.txt">http://bfnet.com/misc/gimp-coolscan-debug-color.txt</A>

|
|
<A HREF="http://bfnet.com/misc/gimp-coolscan-debug-rgbi.txt">http://bfnet.com/misc/gimp-coolscan-debug-rgbi.txt</A>
|
|
<BR>
|
|
<P>Andreas> Please indicate:
|
|
<BR>
|
|
Andreas> You SCSI card, SCSI lowlevel driver, sane version, backend version,
|
|
<BR>
|
|
Andreas> what settings you used with the backend and anything that may
|
|
<BR>
|
|
Andreas> give me an idea on how to reproduce your error.
|
|
<BR>
|
|
<P>My system information is below. As for reproducing the error, I do
|
|
<BR>
|
|
the following:
|
|
<BR>
|
|
<P>1. in shell, export SANE_DEBUG_COOLSCAN=128
|
|
<BR>
|
|
2. run gimp
|
|
<BR>
|
|
3. Xtns->Acquire Image->Device Dialog...
|
|
<BR>
|
|
4. Scan
|
|
<BR>
|
|
<P>The result for Color is usually OK, but sometimes it's blue. The
|
|
<BR>
|
|
result for RGBI is an incomplete scan --- before the scan is finished,
|
|
<BR>
|
|
I see a window of mostly black with just a few colored blocks and
|
|
<BR>
|
|
dots.
|
|
<BR>
|
|
<P>Here are some notes regarding the differences between the color and
|
|
<BR>
|
|
rgbi debugging outputs:
|
|
<BR>
|
|
<P>1. Line 244 of the Scan Mode = Color:
|
|
<BR>
|
|
[coolscan] 5/44/0: Command Sequence Error
|
|
<BR>
|
|
[coolscan] sanei_scsi_cmd: returning 0x00000009
|
|
<BR>
|
|
this error does not appear in the RGBI debug.
|
|
<BR>
|
|
<P>2. Line 388 of the Scan Mode = RGBI:
|
|
<BR>
|
|
xscanimage.input_available: bad frame format 5
|
|
<BR>
|
|
this error does not appear in the Color debug.
|
|
<BR>
|
|
<P>Please let me know if there's any more information I can give you!
