[sane-devel] Xsane 0.996 Canon LIDE50 Ubuntu Karmic

2010-04-25 Thread David Liell
I have done 4 scans at different resolutions as follows: 75, 150, 300, 600.
My scanner won't accept 1200 or 2400. It says Failed to start scanner.
Document feeder jammed.
All scans are too dark and seem to be out of focus.
Also, cannot close Xsane. Have to 'Force Quit'
Scanner works perfectly with Windows.
Cannot attach results due to limitations of this service.
Would appreciate some help.
Thanks...David

[sane-devel] SANE source compilation problems

2010-04-25 Thread m. allan noah
you dont need to compile sane-frontends from devel source. use the
last release, or skip it entirely. scanimage can do most things
scanadf can, and the other programs in sane-frontends are not actively
developed.

 Hi,

 I downloaded source from git repositories (sane-backends and sane-frontends)
 and tired to compile them.

 I have Ubuntu 9.10, needed dev library packages were there.

 sane-backends configure, make, make install was fine.
 sane-frontends configure failed.

 I traced problem down to /user/local/bin/sane-config having line:
 LIBS= -ldl -lv4l1?? -lm -ltiff -ljpeg? -lgphoto2 -lgphoto2_port -lexif -lm
 -lusb?? -lusb? @REGMGR_LIBS@

 When I deleted @REGMGR_LIBS@ from that line, then sane-frontends configure
 run successfully. I didn't care about graphical frontends, so configure
 disabled GUI. Previously gcc tried to find that file and failed to compile
 some tests.

 So, my first question - Is it normal to have something like @REGMGR_LIBS@
 unreplaced with some text after sane-backends make install?

 Then I got to second problem while making sane-frontends - compiling
 scanadf.c failed, make reported error:
 scanadf.c:995: error: ?SANE_STATUS_WARMING_UP? undeclared (first use in this
 function)

 Source for SANE_STATUS_WARNING_UP undeclared problem was in
 /usr/local/include/sane/sane.h (installed by make install in sane-backends)
 on line 74. Missing define is deactivated with #if 0 line above. When I
 changed #if 0 to #if 1 and enabled following two #define declarations,
 sane-frontends make was successful finally.

 Is it supposed to be so, that user needs to manually change something in
 installed files to make sane successfully? Or I found a feature or bug?

 Best regards,
 Ilmars Poikans

[sane-devel] SANE source compilation problems

2010-04-25 Thread Alejandro Imass
It should compile fine in Ubuntu/Debian

Make sure you have these pkgs before you configure:

build-essential
libusb-dev

Cheers,

This part was my fault.  I recently fixed oen sane-config bug and
introduced another.  I've just submitted a fix so if you re-pulled
sane-backends from git and reinstall, this part of the problem should
go away.

Others have replied about the remaining issues once @RESMGR@ typo is
fixed.  sane-frontend in current git contains some next generation
API's that sane-backends has disabled.  The released sane-frontends
package is the one to use with released and git versions of
sane-backends.

[sane-devel] ADF Duplex performance problems

2010-04-25 Thread m. allan noah
On Sun, Apr 25, 2010 at 4:45 PM, Ilm?rs Poik?ns ilmars at delibero.lv wrote:
 Hi,

 I'm running latest SANE from git source on Ubuntu 9.10. I was testing
 scaning A4 on Fujitsu ScanSnap 500 in 300 dpi Color uncompressed using
 scanadf. Everything is fine when scanning only one side of sheet (image size
 24MB). But when scanning with ADF Duplex as source, scanner pauses 3 times
 during scanning. Two 24MB files are saved successfully. Clearly pausing is
 caused by data transfer issues somewhere.

Does this happen on windows?

 Any ideas where could be the
 bottleneck? Scanner can't send data so fast over USB?

Almost certainly.

 Buffer too small for
 USB transfers, so too many data exchange transactions creates delay and
 slowdown of throughput?

You can try increasing the buffer-size option in /etc/sane.d/fujitsu.conf.

 I guess scanner is sending data from duplex scan
 interleaved - data block for front side, data block for back side.

for the low-memory scanners like the S500, yes.

 Inefficient processing of such data in fujitsu-backend? Maybe problem caused
 by scanadf (or any other frontend), that can read images only one by one?
 Any ideas?

as long as you have enough ram in the system to buffer the back side
image, the backend can usually outrun the scanner.


 What is the status of SANE 2.0? Is there any functionality for retrieving
 many images simultaneously from one physical scan, like front and back of
 page during duplex scan, several image regions on pages?

neither of those have been discussed for sane 2.0, but the
'multi-region' idea is probably a not going to happen. The first idea
actually is already supported by the fujitsu backend. The 'low-memory'
option causes the backend to do alternate transfers if required. You
have to inspect the value of the 'side' option before each transfer to
determine which image the next block will be for. This is only useful
with a custom frontend, as nothing commonly used will support it.
