[Digikam-devel] [Bug 125916] New: Problem with opening 16bit TIFF

http://bugs.kde.org/show_bug.cgi?id=125916         
           Summary: Problem with opening 16bit TIFF
           Product: digikam
           Version: 0.9.0-svn
          Platform: Slackware Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: dudasg freemail hu


Version:           0.9.0-svn (using KDE KDE 3.5.1)
Installed from:    Slackware Packages
Compiler:          gcc 3.3.6
OS:                Linux

Opening a 16bit TIFF file (that is generated by an external RAW converter software) is not possible both in digikam or showfoto. More precisely: After clicking on the TIFF file it writes "TIFF file identified" to the console, but the opened editor/viewer shows pretty weird output (black and white overlapped lines, that reminds to the original image).

The file can be downloaded from:
http://amigos.amiga.hu/dudeeg/digikam_tiff/IMG_4224-01.tif


The output from "identify" :

$ identify -verbose IMG_4224-01.tif

Dubas,

I have no problem to see your 'Spider' photograph in Image editor using current trunk implementation. Really nice picture !

I suspect a problem relevant of your libtiff. Can you give me :

- libtiff version.
- messages from the console when you load this image (after to have updated svn).

Note : here, i'm use Mandriva 2006 with libtiff 3.6.1

Hello Gilles,

After compiling digikam just after your "SVN commit 531715" I got the same result :(
My libtiff is 3.7.3 (from Slackware 10.2).

Dubas, Your libtiff messages are correct and similar that mine.

But i suspect that your libtiff is an instable release (3.7.3 version). The 3.8.2 stable release is available since a long time :

http://www.remotesensing.org/libtiff

I recommend you to test with :

- 3.6.x release (like in mandriva).
or
- 3.8.2 release (last stable).

Thanks in advance

Gilles Caulier

NOTE : All my recent commits in stable and trunk branch fix bugs relevant of wrong thumbnails generation (main interface and camera gui) with your TIFF file.

Hi Gilles,

I have not dealt with this problem in the last couple of weeks (since you have posted that Marcel's libtiff 3.7.3 is working perfectly with my system).
The main problem that I have no idea from where to start the check.
I have an official libtiff 3.7.3. slackware package installed, but I cannot see the 16bit TIFF correctly.

If you can give me a hint what to check closely I can do it in 2-3 days.

Thanks,
Gabor Dudas

ps: a small correction: the second letter in my family name is d; however, please feel free to call me Gabor :)

Gabor,

Update svn, and start digiKam from a console. Try to load the tiff image and look the error/warning message from libtiff.

Gabor,

There is no error messages from libtiff... strange.

Are you using PCC like computer or something like that ? 64 bits computer ?

Gilles,

Nope...I am using AMD Athlon. Not really a new model. 1 GHz.
I would like to change my libtiff installation to anothere one, but I don't have too much experience in updating an important system library. I have an official package installed called libtiff-3.7.3-i486-1.
I could easily remove this, but I have found that another official base package, called aaa_elflibs-10.2.0-i486-3 is containing a file: usr/lib/libtiff.so.3.7.3
Any idea about updating?

Thanks,
Gabor

Gilles,

I have updated the libtiff from 3.7.3 to 3.8.2, but the problem is the same :((
(I have not recompiled digiKam after the libtiff update, but I guess I don't have to...)

I am out of idea about what can cause this, but this is really annoying! :)

Regards,
Gabor

Let me add that e.g. Kuickshow perfectly opens that 16bit TIFF, and eg. Konqueror generates the preview perfectly.
