Re: [sane-devel] scanbd on ubuntu
Sorry, this probabely is stupid - but I do not know where to begin. This is the core of my question. (Some hints at sourceforge's project page could be helpful...) You wrote that the old ArchLinux instructions will do. OK - I'll try these and report back.

[sane-devel] gscan2pdf v1.8.2 released
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 1.8.2: * Don't ignore warnings from unpaper * Fix OCR being ghosted when Tesseract is installed. Thanks to Chris Mayo for the patch. Closes merge request 13 * + support for scanimage v1.0.27 signature.asc Description: OpenPGP digital signature -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org

[sane-devel] Coding style/Code quality (was Re: [janitorial] Text file style convention "enforcement")

It's not the tool that's the problem. There's lots of code "beautifier" programs to choose from (too many maybe). The problem is that backend maintainers have their own preferences and they may not be all the same. I can ride roughshod over everybody, convert all code files to the GNU coding standards in a jiffy with automated checking to boot and whack complainers over the head with a quote from doc/backend-writing.txt but that's not gonna make me (m)any friends ;-) > It might be interesting to ask people to run it on a file when they make > a considerable change and there are no known outstanding patches against > the file. Or even if there are outstanding patches which conflict with > style repairs, one can format the patch branch and it should apply. Backend maintainers are free to reformat/sanitize the code for *their* backend whenever they like, IMHO. When co-maintaining, please get some kind of agreement between the co-maintainers first. Whatever style you choose, pick something that's easily checked(/fixed) by a common tool. # People may want to add something to their pre-commit hook. For the # builder(s), if it's in Debian stable that's good enough. > Honestly my greatest concern is that the genesys_gl*.c per-controller > backends will drift further apart.

Sounds like a case of source code cloning. That doesn't scale. Been there, done that. It's hell. Refactor the common functions into a single file, parameterize the differences and you should be able to get rid off a fair bit of code. I haven't looked at the code much but did notice similarities while fixing all the compiler warnings. Maybe we should run a copy-n-paste detector over the code base. > The more the files drift apart, the harder it'll be to a) realize that > fixes should be ported between them and b) that they are substantially > similar, neigh on identical files. Don't port fixes between them. Use a single copy of the code for all of them. Just put each duplicated function in its own separate .c file and include that directly (or declare the function extern), whatever works. You can do this in a separate branch so others can give feedback. I'll be happy to take a peek and give feedback on the general direction. I won't be able to check all the little details. > Anyway, if all goes well I should be receiving four more genesys-based > scanners, including a couple not mentioned on the website.

By all means, do get off-topic, or rather off-on-a-tangent, every once in a while.

Try with "xsane". Do you mean the calibration the scanner does when I turn it on? I (thought I) waited until that was done (I always wait until after the calibration noises end). Or is there some calibration that I actively need to do? There's a calibration option with values "default values", "from internal test", "from preview", and "from options". This should be set to "from internal test". I don't have a scanner at hand and xsane refuses to start without a scanner. So I can't tell you exactly where in xsane this setting is hidden. I think those were the settings I used. I just tried again, deleting my xsane settings before to start with the defaults and "from internal test". Here's the output: https://pastebin.com/gnaBff6z. It does seem to fail at a different point now. If I look at the logs there does seem to be (though my interpretation might be totally off) some calibration info coming from the scanner (starting at around line 8034), but it then fails just after at "sanei_pieusb_cmd_get_scanned_lines".

[sane-devel] scanbd on ubuntu
Hello, I installed the scanbd package on my ubuntu 16.10 - but could not find a fairly recent set of instructions for the setup. There is a very comprehensive one for ArchLinux from 2013, there is a one for ubuntu, but for scanbuttond, which may be outdated as well - and the /etc/scanbd/scanbd.conf does not really speak to me... Does anybody here happen to have a hint? - All I want is the scanner to make a scan when some button at it is pressed.
