SANE
Information
SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, hand-held scanner, video- and still-cameras, frame-grabbers, etc.)
For more information on SANE have a look at the SANE project website
Supported scanners
For a list of supported scanners have a look at this page. Note the SME rpm uses this page.
Server
This is the installation of the server part, you will also need to install drivers on your clients as described in the Client section.
Installation
Install SANE and required packages
yum install smeserver-sane smeserver-xinetd sane-backends --enablerepo=smedev
then post-install, reboot or
expand-template /etc/xinetd.conf expand-template /etc/services expand-template /etc/hosts.allow expand-template /etc/sane.d/saned.conf service xinetd restart
Testing the installation
Finding your scanner
After installation and reboot you should be able to find your scanner with the following command:
sane-find-scanner
The output should look like this:
# No SCSI scanners found. If you expected something different, make sure that # you have loaded a SCSI driver for your SCSI adapter. # Also you need support for SCSI Generic (sg) in your operating system. # If using Linux, try "modprobe sg". found USB scanner (vendor=0x04b8 [EPSON], product=0x010f [EPSON Scanner 010F], chip=LM9832/3) at libusb:001:002 # Your USB scanner was (probably) detected. It may or may not be supported by # SANE. Try scanimage -L and read the backend's manpage. # Not checking for parallel port scanners. # Most Scanners connected to the parallel port or other proprietary ports # can't be detected by this program.
Determining assigned driver
To see which hardware location is assigned to the scanner issue the following command:
scanimage -L
The output should look something like this:
device `plustek:libusb:001:002' is a Epson Perfection 1250/Photo USB flatbed scanner
Aquisition
To make a test scan you can issue the following command specifying the driver you determined in Determining assigned driver.
scanimage -d drivername --format tiff -l 0 -t 0 -x 215 -y 297 > outfile.tiff
Replace drivername with the driver determined in Determining assigned driver, e.g.:
scanimage -d plustek:libusb:001:002 --format tiff -l 0 -t 0 -x 215 -y 297 > outfile.tiff
Uninstall
You can remove SANE from your SME Server with the following command
rpm -e sane-backends smeserver-sane
Client
Windows XP and Vista
In download section, take the ZIP file (sanetwain127.zip and Windowsinstaller (setup127.exe)
Configuration
- index connection
- Hostname => address ip server
- Port => 6566
- Username => user’s name
I made : Get list of devices on startup
- index printer
- I made : Show printer setup dialog before print
- (I have several printers!)
- index Startup
- I made : Acquire preview on program start
- Use as interface language => fr
Usage
SANE TWAIN drivers have many possibilities. SANE TWAIN drivers can be used alone or called from another application (photoshop, acrobat, ...) like a classical usb scanner.
MacOS X
SANE can also be installed on MacOS X, for more information have a look at http://www.ellert.se/twain-sane/.
If you get things working on MacOS X please provide installation instructions here.
Linux
To use SANE on your linux PC you need to install the xsane package.
Configuration
Then configure xsane so that it knows where to find the server with the scanner attached, add a line with the IP address of your server to /etc/sane.d/net.conf on your client PC
nano -w /etc/sane.d/net.conf IP_address_of_your_server
Usage
You can use kooka or xsane or make the acquisition from other software for instance OpenOffice or GIMP.
Client Troubleshooting
Only needed if your client can't find the scanner
Disable saned
/etc/init.d/xinetd stop or config setprop saned status disabled /sbin/e-smith/expand-template /etc/xinetd.conf /etc/init.d/xinetd restart
Start a terminal on your server.
saned -d128
example
# saned -d128 [saned] main: starting debug mode (level 128) [saned] main: trying to get port for service `sane-port' (getaddrinfo) [saned] main: [0] socket () using IPv4 [saned] main: [0] setsockopt () [saned] main: [0] bind () to port 6566 [saned] main: [0] listen () [saned] main: [1] socket () using IPv6 [saned] main: [1] socket failed: Address family not supported by protocol [saned] main: waiting for control connection
If you have “waiting for control connection “, all sounds good. Now on your scanning software, eg Scanimage (name of gui software for sanetwain)
The scanner should start and lines should appear in the terminal.
On the first connection, it often takes a long time and a message like this can appear: Time out reading word from socket Close Scanimage... saned must close up under putty (else ctrl+C to close saned and to come back to the prompt)
Restart ' saned - d128 ' on the terminal and open Scanimage one more time, it should scan! Lines are displayed on the terminal with putty. (type -d for debug mode)
The first time, I didn’t succeed to use the scanner on my windows computer when using sanetwain
=> outdated delay of wait..
I resolved problem by changing the file /etc/sane.d/dll.conf
I put in comment (# in front of the line) all lines which did not correspond to my driver.
Enable saned when finished
/etc/init.d/xinetd start or config setprop saned status enabled /sbin/e-smith/expand-template /etc/xinetd.conf /etc/init.d/xinetd restart
