[sane-devel] Help on Xsane.

2006-08-11 Thread Rupesh Tarpara

Thanks for the information allan, I have one more doubt.

The SANE standard (section 3.2) just tells about image transmission, it did
not gave me details about image file format.
Different devices have different file formats for RAW image such as
raf (Fuji)
.crw .cr2 (Canon)
.mrw (Minolta)
.nef (Nikon)
.orf (Olympus)
.dng (Adobe)
.pef (Pentax)
and any other device file format.

In what file format Xsane expects the image data?

My device is capable of scanning images in different formats (jpeg, Tiff,
bmp ) depending on scan settings.

In what format the Frontend (eg. Xsane, I am using it for testing) expects
image data from backend? (raw or any of jpeg, Tiff, bmp)

[sane-devel] Front Configuration.

2006-07-27 Thread Rupesh Tarpara
I would like to know, how front-end gets the list of all available backends
on the system?

does it look directly into dll.conf file or communicates with sane daemon to
get the list of available backends?

try using the DBG macro in your backend to print some messages from within
sane_init() and sane_get_devices().

then call:

SANE_DEBUG_BACKENDNAME=255 scanimage -L

Replace BACKENDNAME with name of your backend in all caps.

if you dont see your messages, then the dll backend may not be loading
your backend. try using `strace scanimage -L` to be sure.

 Following is the build procedure I have followed.

 I have downloaded sane-backends 1.0.18 source and made the following

 1. I have created a new backend source file for this device.
 2. I have modified sane-backends-1.0.18/configure.in and

 3. executed autoconf, ./configure, make and make install
 4. all libraries were installed at /usr/local/lib/sane

 I modified the /usr/local/etc/sane.d/dll.conf file to include my backend
 name.

 I am using Xsane as frontend. When I run Xsane, it gives error message as

 1) are there any backend configuration steps which I might have skipped?

[sane-devel] How to detect USB scanners on linux?

2006-06-13 Thread Rupesh Tarpara
Hi,

I am using Redhat AS 3, update 7. kernel string 2.4.21-40.EL.

I am developing sane backend for USB hand held image scanner.

Problem :-

When I connect the USB device and run 'sane-find-scanner' command, it does
not detect my usb scanner. It displays error message as, 'make sure usb host
controller driver is installed and kernel scanner module is loaded'.

1) The files present in /dev/usb are :-

scanner0   scanner10  scanner12  scanner14  scanner2   scanner4   scanner6
scanner8
scanner1   scanner11  scanner13  scanner15  scanner3   scanner5   scanner7
scanner9

2) the files present in /etc/hotplug are :-

blacklist  ieee1394.agent  pcipci.rc  usb.agent
usb.handmap  usb.usermap
hotplug.functions  net.agent   pci.agent  usb usb.distmap  usb.rc

3) output of lsmod is:-

can anyone guide me what is wrong? Where to look for usb scanner device

is it necessary to install, usb-serial port emulator driver(kernel module)

 Some time ago I got a nice patch from Dirk O. Siebnich
 from which I made our patch to build our iscan-free package
 which is a really free version of the epkowa backend
 (this means the /usr/bin/iscan frontend was also removed
 because it requires a non-free library).
 
 Julien,
 I would appreciate it if the free version of Iscan would
 be as much as possible the same on Debian and on Suse
 (and on any other distribution).
 If you (or any other distribution package maintainer) are
 interested, please contact me.

I have seen it on our OpenSuSE mirror here at Mandrive. What I have done
now is suggesting to the upstream developers to make two packages, one
with the frontend and one with the backend, to be more distro-friendly.
I have no answer yet, lets see what they say.

Hi,

I am developing backend for USB hand held scanner, for Fedora Core-5.
I have gone through the documentation of SANE standard. I am still not clear

Can any one help me with the implementation of backend?

I've got a Fujitsu 5120C, and with M. Allan Noah's help and his latest
fujitsu backend from cvs, it's working great, using scanimage to talk
directly to the backend.

But, if I use scanimage to connect to saned, it's not working.  I get an
'Invalid argument'

When running saned with 'SANE_DEBUG_FUJITSU=128' set, here's a few lines
of output:

[fujitsu]   depth 1
[fujitsu]   lines 6600
[fujitsu]   pixels_per_line 5104
[fujitsu]   bytes_per_line 638
[fujitsu] sane_get_parameters: finish
[fujitsu] sane_read: start
[fujitsu] read_from_scanner: start

[fujitsu] sane_read: finish
[fujitsu] sane_close: start
[fujitsu] do_cancel: start
[fujitsu] do_cancel: finish

The complete logs can be found here:

http://www.McQuil.com/saned_debug.txt
http://www.McQuil.com/saned_debug_B.txt   (scanimage with the -B option)

The above test was with a SCSI connection (Adaptec 2906). But, I get
very similar results when using USB.


This is a test machine that I loaded Ubuntu dapper on last night,
WITHOUT any sane packages.

I then grabbed the latest from cvs (May 31, 2006 10:30pm EDT), and
built/installed it.

This only seems to be a problem when using saned, which I *really* need.

Any pointers on how to resolve this issue?

Thanks,

I have a C application that runs on Window and Linux. I would like to use
SANE to access a scanner on both windows and Linux so I have a consistent
backend. I've been trying to follow links to SANE on windows, but most of
the links are broken or they are for the front end.



Is there a live Windows SANE backend project or port?



Or is there a better alternative so that my application can have a
consistent backend for scanning? SANE looks great on Linux!



Thanks for the help!

[sane-devel] RE: sane-devel Digest, Vol 11, Issue 50

2006-05-30 Thread Rupesh Tarpara
Hi,

I am new to SANE. I have gone through the sane documentation.

Can anyone guide me how to start developing backend for any scanner? If
possible send me small sample programs for frontend or backend.

Regards,

Rupesh Tarpara

Perhaps redundant, but I have a UMAX Astra 1200S.  It has a 25-pin
Mac-style SCSI connector, and I used it with an Adaptec 2940U
controller with a SCSI-2 to mac-scsi cable and a mac-scsi terminator
and sane under NetBSD with no issues other than image quality which is
kind of lame.
