Thread: QR coder/decoder software?

  1. #1

    Default QR coder/decoder software?

    Does OpenSuSE have any software that can code/decode qr codes?
    I saw this video for a Windows app that does just that. I wanted the same cool thing for SuSE.
    Here's the video: XRen QR Code Tool Trial - YouTube

    You forgot to mention for which openSUSE (not OpenSuSE) level you are searching.
    In any case, when I do a search on software.opensuse.org: Search Results with qr for 12.1, i get several results, amongst them qrencode (silly enough there is no description what it is on the first few results, but on the next page there is). You did not do this search?

    ok, thanks. I just didn't know that you could do a search with an incomplete search term on there.
    I run 11.4.

    This was the description that I found for it when I just did the search:
    Libqrencode is a C library for encoding data in a QR Code symbol, a kind of 2D
    symbology that can be scanned by handy terminals such as a mobile phone with CCD.
    The capacity of QR Code is up to 7000 digits or 4000 characters, and is highly robust.
    Now, knowing what the name of the software is, I was able to do a Google search and found this little tutorial: Create Your Own QR Codes on Linux | Tux Tweaks
    That looks cool. I might try it out.

    ok, I just tried getting qrencode-3.2.0-11.1.x86_64.rpm from the listed KDEistro:Factory/openSUSE_11.4
    and when I tried to install it, I got this message after kpackage manager tried to resolve dependencies.
    nothing provides libqrencode.so.3()(64bit) needed by qrencode-3.2.0-11.1.x86_64
    If I were to try the "1-click install would it detect that I need the 64 bit version and not the i586 version?

    Never use kpacketmanager (or apper in 12.1) use YaST > Software > Software manager, or zypper, or the one-click. In the latter case, better to check so that the repo is dusabled after the install ((or do this yyourself.

    So I got libqrencode3-3.2.0-11.1.x86_64 and qrencode-3.2.0-11.1.x86_64 from the Factory/openSUSE_11.4 repo using the 1-click method.
    It seems to work nicely but I've found one thing (and now I'm sure it has to do with Facebook): When I upload the resulting .png to Facebook, it fails, and then I have to open the code in Gimp and resave it, the file size becomes larger, and then it works for Facebook. I tried another experiment for Google+ and it handled it fine without my having to resave it in Gimp. Go figure. Anyway, I'm having fun with it.

    Thanks for the help!

    If you have one of those scanners, see what these say:

    ok, now how about software that can READ the generated code? At first I thought that qrencode should be able to do that by simply reversing the process but after looking that up, I saw that it can't, at least I didn't see anything having to do with DEcoding in the help file.
    Then I Googled for "linux qr code reader software" but what I found was for Ubuntu packages, Not OpenSuSE Ubuntu's code reading packages start with, "libdecodeqr" And yes, I did go into SuSE's software search but got no results ( software.opensuse.org: Search Results ). This is the page where they talk about it for Ubuntu: Idea #15111: "QR-Code reader for Linux" - Ubuntu brainstorm -- scroll down to the 4th post which was written by "Blizzz".
