[sane-devel] gscan2pdf v2.0.3 released

[Jeff]

gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan.

http://gscan2pdf.sourceforge.net/

Five clicks are required to scan several pages and then save all or
a selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
libimage-sane-perl, scanimage or scanadf, and can scan multiple pages at
once. It presents a thumbnail view of scanned pages, and permits simple
operations such as cropping, rotating and deleting pages.

OCR can be used to recognise text in the scans, and the output
embedded in the PDF or DjVu.

PDF conversion is done by PDF::API2.

The resulting document may be saved as a PDF, DjVu, multipage TIFF file,
or single page image file.

Changelog for 2.0.3:
* Always update image viewer if page selection changes
  Closes Debian bug #893026 (Preview pane does not update)
* Fixed manually typing date in metadata dialog (again)
  Closes Debian bug #893024 (Manual entry into UI date widget is broken)
* If image is zoomed to fit viewer, update zoom when the size of the
  viewer changes
* Update cursor depending on selected tool and position
* Build corrupt session file by hand rather than storing binary file
  that is not universally compatible. Closes bug #293
  (t/175_open_session2.t fails on i686: Long integer size is not
  compatible)
* Convert all scans to PNG to allow tesseract to extract resolution
* Ignore invalid options in profile
* Ignore options in profile that are already within tolerance
* Update to Hungarian translation (thanks to csola)

[sane-devel] test backend

[Jeff]

I know about the test backend, and it is very useful.

However, it cannot cover every combination of option type/reload that is
out in the wild.

I often have to spend hours mocking up a backend from a log file to be
able to reproduce a bug in gscan2pdf, in order then to be able to fix it.

It would be really useful to have a SANE option to test a real backend
without the scanner being present. i.e. instead of calling
sane_device_open, to be able to call sane_device_mock_open or similar,
which would still allow sane_set_option, etc., but would not try to pass
the options to the hardware.

Unfortunately, I assume that to implement something like this, every
backend would have to be changed to separate out the hardware calls.

Would anyone else find something like this useful?

Does anyone have any better ideas for supporting hardware for which
there is no access?

Regards

Jeff

It is an HPLIP issue. My OfficeJet does it too.

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

Thank you so much for helping me trouble shoot all this.
They supposedly have the source code for the driver so I will see if I
can compile that and see if I can find the issue with it. Although I'm
not so sure how it is suppose to work. It is interesting it gets most
of the image and stops near 90+%

I tried on my laptop to make sure it wasn't something in exagear and I
got the same results. So I am sure there is a problem with the driver.

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

Response from brother.

"Hi Jeff.

Any type of sharing feature on a USB model is not supported by
brother. Most questions we received for this are of a Microsoft
nature, but the same policy applies to other OS's as well.

If you are looking to have a machine work on multiple PC's, I
recommend looking into a Network model like MFC-J485DW or something
from the same series."

Hmmm, looks like I need to restate the problem.

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

My code is simply calling scanimage the way I posted here already.
Running the same commands by hand results in the same behaviour. I
have my code write the command it runs in a file called ran.txt, so I
can examine it and run it. I'm just using php to open a 3 pipe method
of running scanimage. it is actually running it under "script" which
allows scanimage to continually write to stdout/stderr without
blocking which gets written to a stdout.txt and stderr.txt files. I
also implemented the ability to send ctrl-c using the 3rd input pipe.
So if my loop that is reading the pipes sees that a certain file
exists and is still running it will send a ctrl-c. My frontend starts
this php script and detaches and then reads it's output files to see
what is going on it also continually loads the image being created by
scanimage. I get the latest page number from stdout.txt/stderr.txt and
the name of the file from my rant.txt looking for '--batch= and the
matching quote and replace all %d with the last page number and then I
have my image retrieve send that file. :-)

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

I wonder it it works the same on a true x86 architecture it could be
something with the brother driver. After those messages are generated
the saned program stays running and tries to process other requests.
However I need to reboot for it to start working again.
I should be able to reset the usb port to get it working again somehow.

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

Progress. I am now able to scan jpeg files :-)
And test out more of my phpsaneng program.
My preview worked awesome. I was able to watch the image as it was
being scanned.

I redid git as recommended in INSTALL.linux

apt remove sane sane-utils
git clone git://git.debian.org/sane/sane-backends.git
./configure --prefix=/usr --libdir=/usr/lib --sysconfdir=/etc
--localstatedir=/var  --enable-avahi
make
make install

it is odd that -V reports as so

root@raspberrypi:~/sane/sane-backends:x86$ scanimage -V
scanimage (sane-backends) 1.0.27git; backend version 1.0.24

Is this something I should be worried about?
Where would it be getting 1.0.24
I tried removing all sane files I could find and then
make install from my git repo and I still get the same output.


Now to try and get saned working
saned use to at least connect to the port but now I get nothing

root@raspberrypi:~/sane/sane-backends:x86$ saned -d128
root@raspberrypi:~/sane/sane-backends:x86$

root@raspberrypi:~/sane/sane-backends:x86$ saned -d128 -b 192.168.1.27
root@raspberrypi:~/sane/sane-backends:x86$

any suggestions on how to get it to report more?
maybe a compile flag to get something from it?

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

It seems to be wanting .la files when I have .so files so is there a
flag to support shared object files over .la?

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

I pulled the current git of sane-backend from
https://anonscm.debian.org/git/sane/sane-backends.git

I did
./configure --prefix=/usr --libdir=/usr/lib/i386-linux-gnu
--sysconfdir=/etc --localstatedir=/var  --
make
make install

now when I run "scanimage -L" it can't see my scanner. Is there a flag
I need to use other drivers than the ones it compiles as the brother
printer driver is a binary package?

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

root@raspberrypi:~:x86$ scanimage --version
scanimage (sane-backends) 1.0.24; backend version 1.0.24

ugh that is old debian-8 image from exagear is a bit dated.

I'll get the current backend and compile that and see if that works.
I have no idea how or if this will work since it is an emulated x86
architecture.

There is also Sourceforge.

I don't have much, if any, free time, but I am a DD, so if help was
needed with the mailing list replacement using Debian infrastructure, I
might be able to lend a hand.

Isn't it just easier to use ImageMagick or GraphicsMagick to convert
from pnm to what you want?

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

I'm using debian in exagear do they compile scanimage without support
for jpeg and png? It is looking like I have to try and put some other
virtual os on my raspberry pi 3 system.

Re: [sane-devel] Weird behavior in exagear.

So, renaming my image from the directly connected method to pmn allows
me to view it. Now to find out what I need to get a jpeg, tiff, png
images.

Re: [sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

interesting I searched for "scanimage # sane data follows" and came across

https://github.com/kkaempf/sane-backends/blob/master/frontend/scanimage.c

and looking at that it looks like I was getting a pnm header even
though I asked for a jpg.
maybe I need to install jpg packages to use scanimage to output a jpeg?

[sane-devel] Weird behavior in exagear.

[Jeff Sadowski]

I started my scanner testing with my project. :-) My project phpsaneng
seems to be working.

The way I want to use my scanner, not so much.

Maybe one of you would know what is happening here. I currently have 2
ways to connect to my scanner. Via saned or using scanimage directly.

I was surprised that both methods fail in two different ways.

using saned from a second server:

/usr/bin/scanimage  "-v" "-p" "--batch=preview.jpg" "--batch-count"
"1" "--format" "jpeg" "-l" "0" "-t" "0" "-x" "215.9" "-y" "355.6" "-d"
"net:192.168.1.27:brother2:bus1;dev1"

results in

scanimage: rounded value of br-x from 215.9 to 215.88
scanimage: rounded value of br-y from 355.6 to 355.567
Scanning 1 page, incrementing by 1, numbering from 1
Scanning page 1
scanimage: scanning image of size 1648x2314 pixels at 24 bits/pixel
scanimage: acquiring RGB frame
Progress: 96%
scanimage: min/max graylevel value = 11/255
Application transferred too few scanlines

hexdump -c preview.jpg.part|head looks like so

I can view this file in most image viewers

directly from the server connected to the printer (a raspberry pi with
exagear to run the brother software)

using

/usr/bin/scanimage  "-v" "-p" "--batch=preview.jpg" "--batch-count"
"1" "--format" "jpeg" "-l" "0" "-t" "0" "-x" "215.9" "-y" "355.6" "-d"
"brother2:bus1;dev1"

results in

And I can clearly see text in the file that doesn't look right.

P6
# SANE data follows

Image viewers say it isn't an image.

Any ideas what is going on given that data?

Is there anything I can run to get more debug data?

Re: [sane-devel] xsane preview scan?

[Jeff Sadowski]

Because I will use the default resolution I will leave out that
argument and I though about if the default scan area for -l and -t
might not always be 0 so maybe I should do this

scanimage --batch=preview.jpg --batch-count=1 --format=jpeg -d  --test-picture=Grid -x  -y  -l 0 -t 0

Exactly. A resolution of 1 is too small. This works fine for me:

scanimage --batch=preview.jpg --batch-count=1 --format=jpeg -d test:1
--resolution=50 --test-picture=Grid -x 200 -y 200

I'm thinking my best bet is to use the default resolution with max x and max y.

[sane-devel] xsane preview scan?

[Jeff Sadowski]

I have been working on a php implementation of a scanner interface.

I am making some progress. I have my code at
https://bitbucket.org/jeffsadowski/phpsaneng

(Not anywhere ready for mainstream as for now it just lists the
options selected when I hit scan.)

I'm at the point where I want to start a preview and I need to make a
decision of how to get a preview.

I don't see a preview option to scanimage and am curious how xsane
gets it's preview.

When I try a preview with xsane with test:1 scanner I get a perfect
grid. (I had set the "Select the test picture" to Grid)

using scanimage '-h' '-d' 'test:1'

I saw the options for test:1

So I tried

scanimage  '--batch=preview.jpg' '--format' 'jpeg' '--batch-count' '1'
'-d' 'test:1' '--test-picture' 'Grid'

which did not come up with the same grid I get in the preview that xsane shows.

I thought well maybe it is getting the max x and y so I tried

scanimage  '--batch=preview.jpg' '--format' 'jpeg' '--batch-count' '1'
'-d' 'test:1' '--test-picture' 'Grid' '-x' '200' '-y' '200'

that wasn't it either.

Then I noticed xsane can only set x and y up to 20 which is weird.
even the defaults are 80 for x and 100 for y

I tried 20x20 and 80x100
but those didn't result in an image that xsane did either.
I also tried lowest resolutions that isn't it either. So I am curious
how xsane acquires a preview?
Or better yet what is the best way to acquire a preview with scanimage?

I think I would want to have the scanner scan as fast as possible so I
thought lowest resolution.
I also think I want my preview of the full bed so max x and max y
the image I get when I try

scanimage '--batch=preview.jpg' '--format' 'jpeg' '--batch-count' '1'
'-d' 'test:1' '--resolution' '1' '--test-picture' 'Grid' '-x' '200'
'-y' '200'

doesn't even look like a grid at all.

So I thought I'd ask this list for some help.

[sane-devel] gscan2pdf v1.8.10 released

[Jeff]

gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan.

http://gscan2pdf.sourceforge.net/

Five clicks are required to scan several pages and then save all or
a selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
libimage-sane-perl, scanimage or scanadf, and can scan multiple pages at
once. It presents a thumbnail view of scanned pages, and permits simple
operations such as cropping, rotating and deleting pages.

OCR can be used to recognise text in the scans, and the output
embedded in the PDF or DjVu.

PDF conversion is done by PDF::API2.

The resulting document may be saved as a PDF, DjVu, multipage TIFF file,
or single page image file.

Changelog for 1.8.10:
* + support for scan options without ranges, e.g. booleans, in tolerance
  check introduced in v1.8.9

Changelog for 1.8.9:
* Rename preference "Open scan dialog at program start"
  -> "Open scanner at program start"
* Fix killing processes on cancel
* Hide extended page numbering checkbox and source document frame unless
  scanner is not capable of duplex and ADF is selected. Therefore, for
  duplex-capable scanners, this is never shown. For duplex-incapable
  scanners, this is shown if the ADF is selected, but otherwise hidden.
* + support for the new API in ImageMagick 7 for unsharp mask
* For single-sided documents, hide rotate facing/reverse/both side
  dropdown.
* + missing documentation for Edit/Properties
* Don't reapply scan settings if value is within tolerance.
  Closes bug #287 (Reload recursion limit (5050) exceeded)
* Fix crash reading corrupt config file
  Closes bug #288 (gscan2pdf-1.8.8 does not run in Ubuntu 16.04)
* Update to Slovak translation (thanks to Dušan Kazik)

The messages specific to scanimage (look at the scanimage source, but
things like progress and error messages, e.g.
https://anonscm.debian.org/cgit/sane/sane-backends.git/tree/frontend/scanimage.c,
line 1919) are not translated, because scanimage hasn't tried to.

However, scanimage just passes on the strings for the option titles and
descriptions from the backend, and these are (often) translated.

Your application can do the same - just pass on the translations from
the backends (remember to use the sane-backends domain for gettext).

Obviously messages from your application you will have to translate
yourself.

NOOO! Google translate is excellent for getting the gist of
something written in a language you don't understand, but the
translations are almost always really horrible.

The standard method for translating applications in C, Perl, etc. is to
mark the strings. Tradition dictates an underscore, e.g. _"string to be
translated" but sane-backends uses SANE_I18N (e.g.
https://anonscm.debian.org/cgit/sane/sane-backends.git/tree/backend/fujitsu.c,
line 3097).

PHP uses a similar method:

http://php.net/manual/en/function.gettext.php

So having appropriately marked your strings, gettext will extract them
into a .pot file, which you can give to your translators (I use rosetta
on launchpad), and you get a .po file for each language with the
appropriate translations (or not).

You convert the .po files to .mo files when you build the application
and install them to the appropriate place, and Bob should be your uncle.

It all works for me. The strings specific to gscan2pdf I have had
translated as above, and I fetch the backend strings from the
sane-backend domain.

Regards

Jeff

Re: [sane-devel] Supported languages?

[Jeff Sadowski]

I'm not sure I grasp it.

So if I install ubuntu on a vm for each language I want to support would I
be able to copy the output for each language?
Or would it be better to do a google translate for the languages? I can add
tables for translating the common options if need be.

Indirectly. scanimage pulls in the option title and description from the
backend. Therefore, if the backend has translations, then scanimage will
pass them on. e.g. fujitsu:

https://anonscm.debian.org/cgit/sane/sane-backends.git/tree/backend/fujitsu.c

  if(option==OPT_GAMMA){
opt->name = "gamma";
opt->title = SANE_I18N ("Gamma function exponent");
opt->desc = SANE_I18N ("Changes intensity of midtones");

SANE_I18N is the C macro that fetches the translations.

Re: [sane-devel] Best way to stop scanimage?

[Jeff Sadowski]

Thank you for the input.

I'm redoing phpsane. I'll look at the others but I came up with a method
that seems to work a little better then I have seen so far. Like I
mentioned I'm using proc_open in a process that I put in the background and
to allow me to watch the image as it is being pulled. I am pulling the
selection interface I saw on phpsane. I talked to the developer of phpsane
and he suggested I rebuild it. I can successfully pull scanner specific
options and create a custom option list for them. I'll add the option to
stop and try it out. But I will caution other users on that. I will cache
options and scanner returns to speed things up.

I was even successful at allowing an array input in html :-)

You are not the first. Have you looked at
https://sourceforge.net/projects/phpsane/ or
https://github.com/anomen-s/php-sane or https://github.com/sbs20/scanserv ?

I should probably point a few things before you continue down the dark
path of making a wrapper around scanimage.

When I started writing gscan2pdf back in 2006, it was exactly that, a
Gtk2 wrapper around scanimage, written in Perl.

It seemed like a good idea to wrap scanimage at the time, but it quickly
became clear that the problem is that you have no way of handling option
reloads. You can make it work for one scanner easily enough, but in a
general sense, it is impossible.

You are completely at the whim of the backend if an option, e.g. source
or depth, option force a reload. And they do, which changes unexpected
things. For instance some scanners support one page size (i.e. scan
size) for flatbed, and another for ADF.

You can work around this by calling scanimage [extra options] --help
every time the user changes an option, but this will be slow. You can
make it quicker by caching the options, but this is error-prone.

You will find that because of this, the order in which the options are
set is vitally important. i.e. for the above example, you have to set
the source option before the geometry options, as the range of geometry
options is changed by source. And confusingly, some backends have
different names for the same options.

In the end, I wrote Perl bindings for the SANE API. This solved all of
the above problems, as you then get reload callbacks:

However, it is non-trivial. Here is a tutorial on writing PHP extensions

Good luck.

If you look at scanimage --device=test --help, you will see that there
is a delay option (along with almost anything else you need to test your
frontend).

Assuming that the de_DE locale is installed, the following should work
(no need to export):

LC_ALL=de_DE LC_MESSAGES=de_DE LC_CTYPE=de_DE LANG=de_DE LANGUAGE=de_DE
scanimage

[sane-devel] simulate a scan with test device?

[Jeff Sadowski]

Most of the systems I am using don't have actual scanners attached. I'd
like to simulate a flatbed scanner by copying an image chunk by chunk with
a delay and even simulate selecting an area and resolution by using a high
def image to copy from and get a lower res depending on the settings I
give. Is this already built into sane-test backend somehow?

When I tried with

scanimage -d 'test:0' --batch="sane-test%d.tiff" --batch-count 1 --format
tiff

I output image was all black and there was no delay

I'm thinking I could simulate this using imagemagick's convert program
and a simple program to copy a bit at a time.

Re: [sane-devel] Best way to stop scanimage?

[Jeff Sadowski]

Thank you Olaf, :-)

I am developing a php interface I'm calling it php saneng I have it on
bitbucket for now and using proc_open. I will send the signal via
proc_terminate giving it the second option being the signal I want to use.
I had a similar project I got working in the past specifically for my
scanner and I seem to recall I was giving it signal SIGTERM and I think
that was causing issues where as when I would test from the command line
and use ctrl+c it would leave the scanner in a usable state. So now that I
read about what ctrl+c sends (SIGINT) I think it would be better to send
that. Maybe there is something wrong with brothers backend that it prefers
a SIGINT over a SIGTERM. I'll experiment and let you know once I get my
project a little farther along. My similar project I had got working was
destroyed when an upgrade failed and I forgot to back it up. No biggy I
should have a better working one in a few weeks.

If I watch the image it is downloading and see it isn't quite right and I
don't want to wait for the scanner to reach the end sometimes it is nice to
stop it there. I think I found my issue I may have been sending it the
wrong signals in the past.
I may have been sending it a signal 9 vs signal 15.

It seems sometimes if I stop it I need to reset the scanner.

[sane-devel] gscan2pdf 1.8.7 released

[Jeff]

gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan.

http://gscan2pdf.sourceforge.net/

Five clicks are required to scan several pages and then save all or
a selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
libimage-sane-perl, scanimage or scanadf, and can scan multiple pages at
once. It presents a thumbnail view of scanned pages, and permits simple
operations such as cropping, rotating and deleting pages.

OCR can be used to recognise text in the scans, and the output
embedded in the PDF or DjVu.

PDF conversion is done by PDF::API2.

The resulting document may be saved as a PDF, DjVu, multipage TIFF file,
or single page image file.

Changelog for 1.8.7:
* + units to scan and edit paper dialogues.
* - unsupported libsane-perl offered as Frontend choice
  Thanks to Chris Mayo for the patch. Closes merge request #19
* Fixed support for Poppler (pdftops) as postscript backend.
  Thanks to Chris Mayo for the patch. Closes merge request #18
* - Reload recursion limit in Edit/Preferences
  Set reload recursion limit as triangular number of number of scan
  options.
  i.e. if there are 5 scan options, the recursion limit is 5+4+3+2+1=15
  Closes bug #275 (reload recursion limit)
* Fixed crash with scanimage frontend due to empty cache
* Ghost save button, rather than hiding save dialogue if all pages
  removed.
  Closes bug #253 (Save dialoque does not stay open)
* Fixed bug causing profile dropdown to be cleared after setting profile
* Filter out integers from tool warnings, analogous to the hex warnings
  from unpaper.
* Fixed visibility of options in save dialogue (again).
* Right mouse click in thumbnail panel makes the page range (e.g. in
  save dialogue) default to "selected".
* Take filename of PDF to email from default filename settings (and
  therefore from metadata). If this produces a blank filename, use
  "document.pdf".
* Fixed bug requiring scan dialog to be requested twice after changing
  frontend
* Update to Hungarian translation (thanks to csola)

If you look at the source of gscan2pdf
(https://sourceforge.net/p/gscan2pdf/code/ci/master/tree/lib/Gscan2pdf/Scanner/Options.pm),
the _parse_scanimage_output() method does what you want.

It is written in Perl, but PHP is not very different.

[sane-devel] parsing help output of scanimage there has got to be a better way?

[Jeff Sadowski]

I am trying to design a web interface like phpsane (developer no longer
working on it)
It looks like he had issue also with parsing the help output as phpsane
didn't work for me.
I had created something like phpsane myself a while ago and was using it
until I upgraded and I lost my web interface.
I was looking if I had to create my own again or if something is out there.

I couldn't find anything so I went at creating my own again. I am really
satisfied with the way I do my php and having it spawn a separate php job
that runs in the background. I had originally customised mine for my
printer but now I wanted to make it more dynamic since I had to rebuild it
anyways.

The extremely hard part is coming up with a way to parse the stdout of
"scanimage -h"
Is there a good way to to this with regular expressions or something.

I have some ways I'm working on that I keep breaking up the string a bit at
a time but it seems exhausting coming up with a parser for pulling the
command line arguments and available options out of that.

Attached is the stdout output of my "scanimage -h"
My first approach was to go after every line that started with - or space -
As you can see in my attached output that approach won't work.
Any suggestions on how to start? Any suggestions on a place to share my
code with others?
I have just started using git on bitbucket for a class I am taking would
that be a good place?
Usage: scanimage [OPTION]...

Start image acquisition on a scanner device and write image data to
standard output.

Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a "=" from multi-character options (e.g. --device-name=epson).
-d, --device-name=DEVICE   use a given scanner device (e.g. hp:/dev/scanner)
--format=pnm|tiff  file format of output file
-i, --icc-profile=PROFILE  include this ICC profile into TIFF file
-L, --list-devices show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
   can be specified: %d (device name), %v (vendor),
   %m (model), %t (type), %i (index number), and
   %n (newline)
-b, --batch[=FORMAT]   working in batch mode, FORMAT is `out%d.pnm' or
   `out%d.tif' by default depending on --format
--batch-start=#page number to start naming files with
--batch-count=#how many pages to scan in batch mode
--batch-increment=#increase page number in filename by #
--batch-double increment page number by two, same as
   --batch-increment=2
--batch-prompt ask for pressing a key before scanning a page
--accept-md5-only  only accept authorization requests using md5
-p, --progress print progress messages
-n, --dont-scanonly set options, don't actually scan
-T, --test test backend thoroughly
-A, --all-options  list all available backend options
-h, --help display this help message and exit
-v, --verbose  give even more status messages
-B, --buffer-size=#change input buffer size (in kB, default 32)
-V, --version  print version information

Options specific to device `brother2:bus1;dev1':
  Mode:
--mode Black & White|Gray[Error Diffusion]|True Gray|24bit Color [24bit 
Color]
Select the scan mode
--resolution 100|150|200|300|400|600|1200|2400|4800|9600dpi [200]
Sets the resolution of the scanned image.
--source FlatBed|Automatic Document Feeder [Automatic Document Feeder]
Selects the scan source (such as a document-feeder).
--brightness -50..50% (in steps of 1) [inactive]
Controls the brightness of the acquired image.
--contrast -50..50% (in steps of 1) [inactive]
Controls the contrast of the acquired image.
  Geometry:
-l 0..215.9mm (in steps of 0.008) [0]
Top-left x position of scan area.
-t 0..355.6mm (in steps of 0.008) [0]
Top-left y position of scan area.
-x 0..215.9mm (in steps of 0.008) [215.88]
Width of scan-area.
-y 0..355.6mm (in steps of 0.008) [355.567]
Height of scan-area.

Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.

* Reapply only those current scan settings that were reset by the reload
* Fixed unpaper detection for v0.3.

[sane-devel] gscan2pdf v1.8.4 released

[Jeff]

gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan.

http://gscan2pdf.sourceforge.net/

Five clicks are required to scan several pages and then save all or
a selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
libsane-perl, scanimage or scanadf, and can scan multiple pages at
once. It presents a thumbnail view of scanned pages, and permits simple
operations such as cropping, rotating and deleting pages.

OCR can be used to recognise text in the scans, and the output
embedded in the PDF or DjVu.

PDF conversion is done by PDF::API2.

The resulting document may be saved as a PDF, DjVu, multipage TIFF file,
or single page image file.

Changelog for 1.8.4:
* Cope with Tesseract 3.0.5 writing Page 1 instead of Page 0
  Thanks to Chris Mayo for the patch. Closes merge request #14
* Assume pixels/inch if the image doesn't know better. Closes bug #258
  (Tesseract 3.05.01: Warning. Invalid resolution 0 dpi. Using 70
  instead)
* Fix paragraph formatting in save as text output.
  Thanks to Chris Mayo for the patch. Closes merge request #16
* In preparation for future removal of libsane-perl frontend, change
  default frontend libsane-perl -> libimage-sane-perl, and similarly
  switch selected frontend on upgrade from older version. Assuming no
  major problems occur, support for libsane-perl will be removed in the
  next release.
* Fixed bug writing postscript file.
* + support for ghostscript backend due to apparent bug in tiff2ps.
* Round scan options with ranges to valid values before applying.
* Fixed bug updating list of option-dependent values. Closes bug #264
  (Effective resolution is 75 DPI despite selecting 600 or 1200).

[sane-devel] SANE Perl bindings Image::Sane released

[Jeff]

I have written new Perl bindings for the SANE API. Please find them at:

https://metacpan.org/pod/Image::Sane

These Perl bindings for the SANE (Scanner Access Now Easy) Project allow
you to access SANE-compatible scanners in a Perlish and object-oriented
way, freeing you from the casting and memory management in C, yet
remaining very close in spirit to original API.

They are based on, and almost identical to, my original bindings:

https://metacpan.org/pod/Sane

which the CPAN administrators have been asking me to rename for
literally years. I updated the Perl API (for error handling) at the same
time, but Image::Sane is otherwise almost identical to Sane.

Regard

Jeff

1. start gscan2pdf
2. set "source" to "flatbed"
3. place the page on the flatbed
4. and click the scan button
5. goto 3. unless all pages have been scanned.
6. click save and select the PDF option.

I'm not sure what you mean. But if you start gscan2pdf from the command
line with the --log=log option, reproduce the problem, quit, and post
the log file, I'll take a look.

Not as part of the scan process, but having produced your (even multipage)
tiff, tiff2pdf will do what you want.

tiff2pdf is the quickest way for those who are happy with the command line.

gscan2pdf would also have no problem importing a multipage TIFF and
saving a PDF.

Re: [sane-devel] Free to a good dev home (USA) - Visioneer OneTouch 8100 Scanner

[Jeff Hanson]

I'm guessing it's Primax.  I did some data captures from WinXP in a VM,
exercising every button along with some test scans including an IT87
calibration target.  Also a OneTouch 9320 scanner with a 35mm
slide/negative scan function (only tested the 35mm backlight since I'm
missing the film templates and it won't scan without them).  Data dumps and
scan PNGs here:

http://www.mediafire.com/file/22yg8tqb17ps9b1/OneTouch_8100.7z
http://www.mediafire.com/file/xgk3387rzgd9pax/OneTouch_9320_USB.7z

IT87 target calibration data:
http://www.mediafire.com/file/03a2590i2zppzas/R141212.zip

I don't need either scanner and will ship them to whoever feels like
working on the SANE driver.  Models from the rest of the product line are
available on eBay.

P.S. If you're wondering why it took 5 years it's because I plugged my
laptop power supply into the scanner by accident and fried it.  It wasn't
until someone gave me another that I remembered to report back on it.

Implementation was a little intrusive because there is no recovery
from calling freopen()  on stdout. This preliminary patch follows
the recommendations of the C FAQ and introduces an explicit
stream variable. I've only done light testing.

$ scanimage --batch 2 /dev/null | cat

Re: [sane-devel] scanimage / tesseract interoperability

[Jeff Breidenbach]

When I run scanimage on a Fujitsu S1500, the program is a little
unhappy even after normal operation, note the return code.  This
is not great for pipelines. Should I attempt a fix? This is version
1.0.23-3ubuntu3 on the latest Ubuntu release. Sorry, I haven't yet
figured out how to configure a vanilla build of SANE from git to
talk to hardware.

$ scanimage --batch
Scanning -1 pages, incrementing by 1, numbering from 1
Scanning page 1
Scanned page 1. (scanner status = 5)
Scanning page 2
Scanned page 2. (scanner status = 5)
Scanning page 3
scanimage: sane_start: Document feeder out of documents
$ echo $?
7

Second, I'm attaching a slightly newer version of the patch that
emits filenames to stdout. No functional changes, I just tried to
match the surrounding code style a little better. Hopefully I got
the tab situation more or less correct. Does it look good?

$ scanimage --batch

Re: [sane-devel] scanimage / tesseract interoperability

[Jeff Breidenbach]

Thank you, Allan. Tesseract will also accept image data directly
on stdin, so single scan mode should work just fine.  I think it is
cleaner to use stdout as opposed to stderr for filenames. I will work
on a patch.

There is one possible alternative. Scanimage could emit image data
to stdout using one of the multi-image formats. For example, multi-image
PNM is simply the concatenation of individual PNM files. Let me know if
you prefer that instead.

Cheers,
Jeff

Re: [sane-devel] scanimage / tesseract interoperability

[Jeff Breidenbach]

Jeffrey, gscan2pdf is terrific and I expect most users will prefer
the friendly graphical user interface. I would love to compare
notes with you on PDF generation nuances, and also coordinate
with respect to future Tesseract releases.

It's also good have the command line programs connect
together nicely through pipes, in the unix tradition. The
necessary modifications on the Tesseract side are almost
ready, so it is a good time to look at the scanimage side.

Cheers,
Jeff

Re: [sane-devel] scanimage / tesseract interoperability

[Jeff Breidenbach]

Thank you Simon, the --batch-script feature looks very flexible.
It almost does the trick:

   scanimage --batch --batch-script (echo) | tesseract - -

Unfortunately, it runs just a little too early. The script executes
just before the temporary image file is renamed. Tesseract
wants to know about the final filename after it exists.

My very first implementation attempt didn't work; the emitted
filename somehow ended up in the image data. Is there a problem
with scanimage writing to standard output?

  if (new_interoperability_feature) fprintf(stdout, %s\n, path);

I ultimately hope to make scanimage and tesseract work
together nicely for everyone. So any suggestions or advice
are appreciated.

Cheers,
Jeff

[sane-devel] Seeking Odd-Page Vertical Flipping to Support ADF-Duplex

[Jeff Rush]

I'm working in the sane-epson2 backend, trying to get it to fully
support adf-duplex for scanning both sides of a page, for the Epson
ES-H-300 scanner.

I've just submitted a patch (#313667) to enable the duplexing.  It
works, and now I have a button on XSANE under Advanced Options.  However
the even (backside) page is 180-degrees rotated.

So as I'm looking thru the driver source, I thought I'd ask if there is
a standard configuration/setting in one of the internal data structures
I can use to cause every other page to be vertically flipped?

If not, I'm going to add to the epson2 driver some logic to invoke
sanei_magic_rotate() on the even-numbered pages, conditionally upon
whether the adf-duplex feature is enabled.  It seems this kind of logic
would be useful to others, and perhaps even already in the code someplace.

Suggestions or guidance welcome.

[sane-devel] SANE packages PPA?

[Jeff Kowalczyk]

It would be very helpful if there were an official PPA for SANE .debs.

Ubuntu 9.04's use of libsane-1.0.19-23ubuntu7 would probably bring a
substantial influx of willing testers with hardware, if there was an easy
way to track 1.0.20 releases with an entry under sources.list.d.

Could the git snapshot machinery be extended to build .debs?

Right, Personal Package Archive, a convention for Ubuntu (and Debian)
users to publish .deb packages on Launchpad. If an individual were
publishing the SANE test packages, a PPA might be a good choice.

But I guess what I really had in mind was an official SANE APT repository,
such as the way WINE publishes their unstable packages:

[sane-devel] scanning doc takes forever

[Jeff]

I am trying to scan a complete letter size at 600 dpi on a Canon FB630U 
using Xsane. It started scanning but I gave up waiting after 5 minutes. 
The scan bar steps a little and hesitates, steps a little, hesitates, 
etc, etc.
 Under Windows it take ~1 minute to complete the scan at 600 dpi.

Any way this can be speeded up??

[sane-devel] Force wake/detection of Fujitsu fi-60F (epjitsu) USB-plugged before firmware files installed?

[Jeff Kowalczyk]

I am having trouble accessing an epjitsu Fujitsu fi-60F at a remote site.
The scanner was plugged in yesterday, the host PC has not been rebooted,
and I would like to avoid doing that during business hours.

The host PC is Ubuntu 8.10 desktop, libsane-1.0.19-6ubuntu1:

$ scanimage -V
scanimage (sane-backends) 1.0.19; backend version 1.0.19

My user is in the scanner group:

 $ grep scan /etc/group
 scanner:x:105:hplip,(...),myuser

The default package epjitsu.conf is as follows:

 $ cat /etc/sane.d/epjitsu.conf 
 # For scanners connected via USB on a known device (kernel driver):
 #usb /dev/usb/scanner0
 
 # For scanners connected via USB using vendor and device ids (libusb):
 #usb VENDORID PRODUCTID
 
 # NOTE: if you have to add your device here- please send the id and model
 # to the author via email, so it can be included in next version. kitno455 at
 # gmail dot com - with epjitsu in the subject line
 
 # these devices require a firmware file in order to function
 # it can generally be found inside C:\windows\fjsti.cab or
 # C:\windows\fjmini\*.cab
 # open that file and look for a ~65K .NAL file with the scanner's name
 # and copy it someplace sane can reach it. then update the line below.
 # NOTE: the firmware line must occur BEFORE the usb line for your scanner
 
 # Fujitsu fi-60F
 firmware /usr/share/sane/epjitsu/60f_0A00.nal
 usb 0x04c5 0x10c7
 
 # Fujitsu S300
 firmware /usr/share/sane/epjitsu/300_0A00.nal
 usb 0x04c5 0x1156

The firware file is in place, but was not at the time the scanner was
plugged in:

 $ ls -al /usr/share/sane/epjitsu
 total 80
 drwxr-xr-x 2 root root  4096 2008-04-28 13:09 .

 -rw-r--r-- 1 root root 65793 2008-04-28 16:17 60f_0A00.nal

sane-find-scanner finds the device as a USB id, but does not
identify or associate it with the epjitsu backend:

  $ sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  found USB scanner (vendor=0x04c5, product=0x10c7) at libusb:005:004
  # 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.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.

However, scanimage does not find the device at all:

 $ scanimage -L
 
 No scanners were identified. If you were expecting something different,
 check that the scanner is plugged in, turned on and detected by the
 sane-find-scanner tool (if appropriate). Please read the documentation
 which came with this software (README, FAQ, manpages).

Are there any utilities to force detection and/or waking of this device,
or is my best option to reboot?

Thanks.
