scanimage --source parameter inactive

[andi-blafasl]

Hi, first I would like to thank you for your great work with this scanner server interface! It is by far the best I have seen yet. And it works nearly out the box! I have a little Problem with my Canon CanoScan N670U: "scanimage --help" reports the --source parameter and the possible options for it but marks it as "inactive" --8<--8<--8<--8<-- --source Normal|Transparency|Negative [inactive] Selects the scan source (such as a document-feeder). --8<--8<--8<--8<--

Your script picks up the Option and set them while scanning. But the Scanner will not scan with the --source option set to anything and scanimage reports the following error message: "scanimage: attempted to set inactive option source"

I tried to understand your code and implement a workaround if the option is reported as inactive by scanimage but I'm not very good in PHP ;-)

Maybe you can implement some checks for the "inactive" statement? That would be great!

Kind regards, Andreas

until i fix that you can remove --source from the $cmd variable on line 854 of index.php it is a dirty fix, but will work before: $cmd="scanimage -d \"$DEVICE\" -l $X -t $Y -x $SIZE_X -y $SIZE_Y --resolution $QUALITY --source $SOURCE --mode $MODE $LAMP--format=ppm"; after: $cmd="scanimage -d \"$DEVICE\" -l $X -t $Y -x $SIZE_X -y $SIZE_Y --resolution $QUALITY --mode $MODE $LAMP--format=ppm";

Can you post the full output of scanimage --help or just grab it off the scanner info page http://127.0.0.1/index.php?page=Device%20Notes then click the device url edit: my umax appears to be the same way with the --source option almost done with this one my umax changed it's default from Normal to Inactive @.@

Thank you for your fast replay. The quick and dirty Fix is implemented and it works! Here is the full output ot scanimage --help

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-scan            only 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

Thanks for the help data, just got the fix made, will be pushed when i get some more new bugs fixed

[GM-Script-Writer-62850]

This should be fixed now, clone git and test it, be sure to clear your browser's cache and rescan for scanners edit: http://www.mediafire.com/download/bjtd14l3v2wufji/PHP-Server-Scanner-1.3-1-dev.tar.bz2 - dev copy

[andi-blafasl]

Tested your new version and it works out the box. This scanner web interface is the best!

By the way, it does not save the theme-settings from config-page ;-)

[GM-Script-Writer-62850]

Check your browser's cookie settings, they must be disabled for the color changer effects to not work you could download the current dev version from the change log page and if you have any theme color suggestions please share, you can test any home made theme by uncommenting this line

[andi-blafasl]

Regarding the color changer and cookies, I found a reason. If I use the full qualified domain name of my pi the cookie is set and the color change is saved. If I use the hostname only, no cookie is set in chrome and IE complains about "intranet settings disabled". I have to do some more research about the problem.

[GM-Script-Writer-62850]

Sounds like i am detecting the url wrong as far as the cookie is concerned, i would not suggest testing the login feature under that setup as it would make login in impossible it works here under 10.0.0.50, 127.0.0.1, m4a79xtd-evo.local, and my [snip].dyndns-home.com
