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.

I see.  So you're just layering on top of scanimage.  I thought you we
using a PHP layer on top of the SANE C API.  Sorry for overthinking
things.  The image acquisition logic in scanimage is correct so the
problem appears to be in the brother backend.

Sorry for the detour,

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. :-)

which indicates that the image acquisition loop ended prematurely for
some reason.  While saned will happily continue to serve requests, how
the backend and scanner react to this depends on the scanner's firmware
and the backend's implementation.  It may very well be that the scanner
expects more read requests and refuses to reply to anything else while
the backend won't send any of those but instead tries to start a new
scan in vain.

Based on what you wrote so far, I think this is a bug in the third party
brother backend you seem to be using.  The only people that can help you
with that are the brother backend developers.  There is nothing the SANE
developers can do about it.

That said, are you sure *your* code is doing the right thing?  That is,
does it read data until sane_read() returns SANE_STATUS_EOF?  Or is it
just reading the number of pixels expected based on the results of a
sane_get_parameters() before you call sane_start()?  The latter is the
*wrong* way to read image data.

Hope this helps,

This is not something to be worried about.  All backends have their own
version, independent of the sane-backends version.  The epson2 backend
for example is at 1.0.124!

The scanimage utility gets it version directly from sane-backends, hence
1.0.27git for a development version after 1.0.27.

Some backends, and probably third party ones in particular, use the
version of the sane-backend's release that they were built against.

Hope this clarifies,

usbreset that I get here allows me to start another scan

 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]

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.

 The dynamic loading should look for .la files first and failing to find
 those, look for .so files.  You don't need any flag for that (and AFAIK
 there isn't one).

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?

The dynamic loading should look for .la files first and failing to find
those, look for .so files.  You don't need any flag for that (and AFAIK
there isn't one).

The backends you built are installed below /usr/lib/i386-linux-gnu/sane/
as libsane-$backendname.$extension, right?  Where is the backend of that
brother binary package installed?

If it's not in the same directory, you need to tell the loader to look
in the directory where the brother binary package installed its
backend.  Let's say that is /opt/brother/sane, then you'd have to run

  LD_LIBRARY_PATH=/opt/brother/sane scanimage -L

Alternatively, you can make a symbolic link to the brother backend from
/usr/lib/i386-linux-gnu/sane/.  Using the same example location

  cd /usr/lib/i386-linux-gnu/sane
  ln -s /opt/brother/sane/libsane-$backendname.$extension

Hope this helps,

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?

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

Support for JPEG and PNG output was added to scanimage in 1.0.25.  So if
you have that (and your distribution enabled it), you don't need either
of the *Magick's.  Note that there were some bugfixes to the JPEG and
PNG support in 1.0.27.

Hope this helps,

That may depend on the Debian version and architecture you're using.
You can check the package dependencies with

  dpkg-query -W -f '${Depends}\n' sane-utils

On my machine (Devuan ASCII, approximately Debian 9), I get

  adduser, lsb-base (>= 3.0-6), update-inetd, debconf (>= 0.5) |
  debconf-2.0, init-system-helpers (>= 1.18~), libavahi-client3 (>=
  0.6.16), libavahi-common3 (>= 0.6.16), libc6 (>= 2.15), libieee1284-3,
  libjpeg62-turbo (>= 1.3.1), libpng16-16 (>= 1.6.2-1), libsane (>=
  1.0.24), libsystemd0, libusb-1.0-0 (>= 2:1.0.8)

So, as mentioned already in my previous reply, I can use JPEG and PNG
but not TIFF.

Hope this helps,

Your scanimage needs to be linked to JPEG, TIFF and PNG libraries.  You
can check with

  ldd $(which scanimage)

On my machine I get

  $ ldd $(which scanimage)
linux-vdso.so.1 (0x7fffa9f9a000)
libsane.so.1 => /usr/lib/x86_64-linux-gnu/libsane.so.1 
(0x7f11434ed000)
libpng16.so.16 => /usr/lib/x86_64-linux-gnu/libpng16.so.16 
(0x7f11432ba000)
libjpeg.so.62 => /usr/lib/x86_64-linux-gnu/libjpeg.so.62 
(0x7f114304f000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x7f1142cb)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x7f1142aac000)
libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x7f1142892000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x7f114258e000)
/lib64/ld-linux-x86-64.so.2 (0x7f1143902000)

So I can scan directly to JPEG and PNG but not to TIFF.

If you're compiling scanimage yourself from source, you need to have the
development packages installed before you ./configure.

Hope this helps,

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.

 Maybe one of you would know what is happening here. I currently have 2

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

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"
