TIFF-File Problems (still)

[Olaf Gellert-2]

Hi,

in the last days I upgraded my OS to SuSE-Linux 10.0.
And right now I compiled digikam 0.8. On the first
start of digikam I get some output like this:


########################################################
> > digikam
digikam: No locale found in database
digikam: Locale found in configfile
digikam: Successfully upgraded database to sqlite3
Checking database consistency
Checking Albums..................(271 Albums) OK
Checking Tags....................(69 Tags) OK
Checking Images..................(0 Images) OK
Checking ImageTags...............(0 ImageTags) OK
Checking Album icons ...............(271 Album Icons) OK
Checking Tag icons ...............(69 Tag Icons) OK

All Tests: A-OK
digikam: ScanLib: Finding non-existing Albums: 22657 ms
QTime::setHMS Invalid time 00:05:95.000
digikam: ScanLib: Finding items not in the database or disk: 837296 ms
digikam: ScanLib: Updating items without date: 3398 ms
########################################################

So I guess digicam is working. But:

Still only blank thumbnails are created from my TIFF-
files (JPEG works fine).

Additionally there seem to be problems with MSDOS (vfat)
file systems. I do have all my albums on an vfat partition.
Digikam displays some shortened directory-names (though
it does not display any images contained in them). The full
names of the directories are displayed, too (and these
work fine). This did not happen with digikam 0.7.4 and earlier.

Have a look at the screenshot at:
http://www.arasca.de/tmp/digikam-screenshot.gif
where you can see both problems...

Cheers, Olaf

If your TIFF files are in 16 bits / color/ pixel, it's normal because digikam
0.8.0 do not support this bytesdepth. current instable source code on svn
(future 0.9.0) support now 16 bits images.

If you have a doubt about your tiff files, try 'identify' tool from IM with
--verboze option.

You can send me a sample to test here if you want (outside the ML ==> caulier

It sounds like a compression problem. Maybe Imlib is not compiled with the support for the compression applied to your tiff files.

Well, good idea. But see the output of "identify -verbose"
(from ImageMagick). It is not 16bit, and it is not compressed
at all. You can find this example image at:

http://www.arasca.de/tmp/beispiel-digikam.tif     (338 KB)

Still at loss with this... Sorry for bothering you
with this (would like to find the error own my own)
but here I am stuck... If it works on your system
I really may have to compile imlib by myself (right
now I am using the thing that comes with SuSE linux).

Cheers, Olaf

Tested with digikam 0.8.0 (and 0.9.0 alpha from svn) without problem under
mandriva 2005 and 2006.

Thanks Gilles and the others, the TIFF file issue seems to be
resolved. I installed an actual RPM of Imlib2 (which is
remarkably bigger than the SuSE rpm) and TIFF display works
now.

The issue with the MSDOS/VFAT names still remains, though
(see attached image).


Cheers, Olaf
