I am using Python 3.4.0 with the following code (I have not tested with other minor versions):

import pyinsane.abstract as pyinsane
device = pyinsane.Scanner(name='epkowa:net:192.168.1.8')

This works in Python 2.7.6. However, I get the following error in Python 3.4.0:

AttributeError: 'str' object has no attribute 'decode'

I believe the str.decode() method was dropped in Python 3, which is why the error is getting thrown due to this line in the Scanner constructor:

self.name = name.decode('utf-8')

Since a string in Python 3 is already Unicode, perhaps there could just be a check on the parameters to see if they are already Unicode before attempting to decode them?

Hi!

I am thinking of packaging paperwork, which requires pyinsane. To package the latter, it would be nice to have a version number or a versionning scheme.
Any hint ?

Thanks,

While in linux system it the scan_adf.py and scan.py are working fine, but in windows systems the scripts are generating very long images. Please see attachment.
Height of scanned image is 9000 px.

Is there a setting which can be set to correct this issue?

Hi

trying to scan in Flatbed mode using Paperwork 1.2.2it says

Error while scanning. No paper to scan

Anyway native Microsoft WDS Driver works perfectly except duplex scanning

This is the list of the both drivers options
epson2.txt

I have an Epson DS-310 document scanner (feeder only, no flatbed). It works fine with sane (scanimage) and simple-scan but when I click the scan button in paperwork (1.2.4) it tells me "Scanner not found (is your scanner turned on ?) (error was: <class 'pyinsane2.sane.rawapi.SaneStatus'>: Data is invalid (4))". I installed paperwork via stdeb / pypi-install on an up-to-date Debian unstable.

I've attached paperwork's diagnostics: paperwork-diagnostics-epson-ds-310.txt

Hallo,

I'm switched from 1.2.1 to the latest version of pyinsane (1.3.1) on a Ubuntu 13.04 64bit (fully updated).
I have an HP OfficeJet 6700 Premium.

Now, when i try to scan from ADF i have this error:

pyinsane.rawapi.SaneException: <class 'pyinsane.rawapi.SaneStatus'> : Error during device I/O (9)

To reproduce this issue simply run :

import pyinsane.abstract as pyinsane

devices = pyinsane.get_devices()
assert(len(devices) > 0)
device = devices[0]

print("I'm going to use the following scanner: %s" % (str(device)))
scanner_id = device.name

if not "ADF" in device.options['source'].constraint:
    print("No document feeder found")
else:
    device.options['source'].value = "ADF"
    # Beware: Some scanner have "Lineart" or "Gray" as default mode
    device.options['mode'].value = 'Color'
    scan_session = device.scan(multiple=True)
    try:
        while True:
            try:
                scan_session.scan.read()
            except EOFError:
                print ("Got a page ! (current number of pages read: %d)"  % (len(scan_session.images)))
    except StopIteration:
        print("Document feeder is now empty")
        for idx in range(0, len(scan_session.images)):
            image = scan_session.images[idx]

the output is:

francesco@xyz:~$ python test.py

Thank you

Packaging pyinsane would require the presence of a full copy of the GPLv3 in the source tree.
Thanks!

Hello everyone,
so I successfully installed pyinsane2 and started to run scan.py in my console (the comand was ..\examples>pyhton scan.py [-h](is '-h' the right thing to do for the first time running?)). The ouput of that was Output file: [Looking for scanners...
pyinsane2\wia\rawapi.py: 72: RuntimeWarning: Pyinsane: Warning: WIADevMgr -> CreateDevice() failed
Failed to access scanner (' {6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\000', 'MX410 series _6277DE000000') : WIA: Failes to open (6BDD1FC6-810F-11D0-BEC7-08002BE2092F).
Whats the problem here? I don't know if the number helps, but I'm hoping that someone might recognizes the order of the numbers and letters and can tell me what kind of number this is, so I could figure out what scanner it is referring and unable to access to.
I get the same error when running [python list_all.py]
I'm running python 3.6 on a windows 8 Computer and don't have WIA2 installed manually, but apprentley that comes with installing pyinsane2...?!

I got past the first compilation issue (missing "atlbase.h") by installing Windows Driver Kit, but now I get too much of a generic error:

The problem we're running into is, once a scan is initiated and the image is retrieved, there is no way to garbage collect the now dead session and end the thread safely. It remains alive holding the device hostage. Any attempt to .cancel() or del() the scan/session object results in python hanging/deadlocking.

An strace reveals that it's sitting on a FUTEX_WAIT_PRIVATE:
ioctl(0, SNDCTL_TMR_STOP or SNDRV_TIMER_IOCTL_GINFO or TCSETSW, {B38400 opost isig icanon echo ...}) = 0
rt_sigaction(SIGWINCH, {SIG_DFL, [], SA_RESTORER, 0x7fc3f45b30e0}, {0x7fc3ee3c5a50, [], SA_RESTORER|SA_RESTART, 0x7fc3f45b30e0}, 8) = 0
futex(0x248d0d0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...>

It's 100% percent repeatable here:

#!/usr/bin/python2.7
import pyinsane.abstract_th as pyinsane
dev = pyinsane.get_devices()
tmp = dev[0].scan()
try:
    while true:
        tmp.scan.read()
except EOFError:
    pass
tmp.scan.cancel()
#or 
tmp.scan.__del__()

Maybe we're not quite understanding how to end and start a new thread/session?

While installing via pip install pyinsane2

returns message

    cl : Command line warning D9025 : overriding '/DNDEBUG' with '/UNDEBUG'

I understand that it can't find the properties file, but I don't know how to fix this.

Thanks in advance

Hallo,

I'm using an HP Officejet 6700 with Ubuntu 13.10 and the latest Pyinsane.
"Color" and "Gray" scan mode work without problems, but "Lineart" produces messed up images (something like "skewed").

You can verify this issue running your scan.py test program from the sources of pyinsane library (changing scanning mode from 'Color' to 'Lineart' at line 70).

Thank you very much,
Francesco

It will be amazing. Can I get progress of scanning, in this version of library?

see https://github.com/python-imaging/Pillow/blob/master/Sane/sanedoc.txt
Perhaps we could merge effort here.

(Windows only)
Old scanners don't have support for the WIA API. So the Twain API should be supported as well.

Currently there are no tests on ADF support.
I tend to break things.

At least one automated test would be nice (I would have to add a message at the beginning of the tests saying "please insert 4 pages in your ADF" or something like that).

NameError: name 'SANE_LIB' is not defined

hi, I don't know why 'name 'SANE_LIB' is not defined'
did I miss something?

Everything is working fine with my pyinsane2 module, I just want to change the saving location of the scanned document, because right now, the document gets stored in the folder your script, that you run to scan, is stored in as well. This comes from line 107 in scan.py: img.save(output_file, "JPEG").
Any tips on what to change for a specific location?
And also, but I don't think this is very important, what does "JPEG" stand for in this case(I know this stands for an image ending, but what particular)? I can type in test.pdf and a pdf document will be created.

Hi everyone,

I'm trying to scan duplex cards with my scanner (fi 7160) in Windows 10, but all that I get is images like this:

The output of list_all is:

In python 2.6 sys.version_info is a tuple and version_info hasn't attribute major.

The following command is good for all python version.
sys.version_info[0]

Honestly is driving me crazy for the last 2 days :(

When a program uses abstrat_th and halts, it segfaults.

What happens:

• The main thread of the program disappear
• The Sane thread decided to halt
• When X tries to cleanup everything that belongs to the Sane thread, the Python interpreter segfault

The problem comes from either libsane + threads or ctypes + threads.

This is a really minor issue, since the program is pretty much finished when it happens. Still, segfaults are not good features :p

Does support scanners (probably an ADF type) for simultaneous two-sided scanning?
Great project btw!

Thanks.

My network scanner is not detected.

I've found the following message talking about network scanner detection, in another context. I've understood that the second argument to sane_get_devices needs to be "false" in order to enable network scanner detection :
http://lists.alioth.debian.org/pipermail/sane-devel/2003-February/006603.html

So in rawapi.py I've changed line 519 from :

def sane_get_devices(remote=True):

to :

def sane_get_devices(remote=False):

Now, paperwork correctly finds my network scanner. But scanner detection is slower.

I don't know if this solution can be made as default, I don't know if there is any other result when modifying this...

The Brother MFC-495CW (using the brscan3 drivers) has 3 possible sources:

• 'FlatBed'
• 'Automatic Document Feeder(left aligned)',
• 'Automatic Document Feeder(centrally aligned)'

Currently, Pyinsane only looks for a source called "ADF".

The end result is that it reads the first document, then feeds the rest without reading. The tests end stuck in an infinite loop.

Hi there,

I am trying to automate sccanning a batch of document with a script in python using Pyinsane2. But when I Call the scan_session = device.scan(multiple=True) routine I get the mesage "Pyinsane: Stream::QueryInterface(): Unknown interface requested" several times, and the python and if i press enter it returns an empty scan_sessions.images, and doesn't proceed to the next sheet.

I am using python 3.6 in a Windows 10 with WIA2, the scanner is a Lexmark all-in-one Mx410de and the connection is over lan.

Any guesses on How to fix this? Thanks

Hello,
when running any of the files of this rep, after I have succssefully build and installed the setup.py file, it gives me ModuleNotFoundError: NO module named 'pyinsane2'.
Has anyone experienced this before or can help me with fixing this ?
The module is listed under installed modules and it is added to my SYS.PATH.

With the device Brother MVC-J410 the follow line of code produce the follow error masage.

device.options['mode'].value = 'Color'

Hello
I'm trying to use Paperwork 1.2.4-20-ga29c3cb on Linux Mint 18.1 Cinnamon 64 Bit. The Brother DCP-130C works fine with Simple Scan but not with Paperwork. I get the following error. Is there a work around?

Cheers Ivan

I wasn't sure if I should submit this as an issue because I don't know if this a problem with my code or the pyinsane library. I'm building a Qt (PySide) GUI application and utilizing threading through the QThread class. I am using the pyinsane.abstract_th module for scanning.

I am able to execute a scan successfully when pushing a button on my application. After the scan completes, I can execute another scan. The problem is the third attempt at execution, which hangs indefinitely. It hangs when attempting to set options for the scan. Here is the snippet of code where the hanging occurs:

def _get_scanner():
    print('Inside _get_scanner()')
    scanner_name = 'epkowa:net:192.168.1.8'
    return pyinsane.Scanner(name=scanner_name)

def scan(mode=None,res=None,source=None,filename=None):
    print('Inside scan()')
    scanner = _get_scanner()

    #For Testing
    devices = pyinsane.get_devices()
    if (len(devices) <= 0):
        print('No scanner detected!')
        sys.exit(1)
    print('Devices detected:')
    print('- ' + '\n- '.join([str(d) for d in devices]))

    print('Setting scan options...')
    # HANGS AFTER PRINTING THE ABOVE LINE
    try:
        scanner.options['resolution'].value = res
    except (KeyError, pyinsane.SaneException) as exc:
        print('Failed to set %s to %s: %s' % ('resolution', str(res), str(exc)))

I noticed that when I retrieve the available devices, my network scanner (epkowa:net:192.168.1.8) is found the first execution, but then is not in subsequent executions (button pushes). However, even though it is not found in the second attempt, the scan still completes successfully.

I have also tried this with the pyinsane.abstract module, which will execute one scan just fine. However, on additional attempts I get the following error after executing scanner.scan(multiple=False):

Traceback (most recent call last):
  File "main.py", line 90, in process
    docscan.scan(self.mode, self.res, self.source, self.filename)
  File "/home/dev/python_projects/scanimage_gui/docscan.py", line 38, in scan
    scan_session = scanner.scan(multiple=False)
  File "/home/dev/python_projects/scanimage_gui/pyinsane/abstract.py", line 455, in scan
    scan = SingleScan(self)
  File "/home/dev/python_projects/scanimage_gui/pyinsane/abstract.py", line 273, in __init__
    self._init()
  File "/home/dev/python_projects/scanimage_gui/pyinsane/abstract.py", line 175, in _init
    rawapi.sane_start(sane_dev_handle[1])
  File "/home/dev/python_projects/scanimage_gui/pyinsane/rawapi.py", line 674, in sane_start
    raise SaneException(SaneStatus(status))
pyinsane.rawapi.SaneException: <class 'pyinsane.rawapi.SaneStatus'> : Error during device I/O (9)

I have tried deleting the Qt worker and thread objects in my PySide application after the scan completes to make sure the thread has released its handle on the scanner, but that doesn't seem to make a difference.

Again, I'm not sure where the issue lies, but I thought I would at least throw this out to narrow down the problem. By the way, everything works correctly when not using threading. I can execute as many scan operations as I want. I want to use threading, though, due to GUI blocking issues in my Qt app.

Please let me know if you would like additional code to review.

Thanks!

Hi,
I installed this library and testing it on my OS X.

Everything is ok for the installation.
When i try to make a demo code.

import pyinsane.abstract as pyinsane
devices = pyinsane.get_devices()
Traceback (most recent call last):
File "", line 1, in
File "build/bdist.macosx-10.11-x86_64/egg/pyinsane/abstract.py", line 473, in get_devices

AssertionError

Can you have a look on this one?

I have a use case where I need to scan 2 different scanners at the same time. when I attempt to multi thread pyinsane2 I get the following
TestScanMultiple.txt

error. attached is the python script that generated this error. Any help would be greatly appreciated.
