[Bug 185279] New: Raw pictures from Panasonic LX2 have totally wrong colours in digikam show modus

https://bugs.kde.org/show_bug.cgi?id=185279

           Summary: Raw pictures from Panasonic LX2 have totally wrong
                    colours in digikam show modus
           Product: digikam
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           digikam 0.9.5-beta3 (using KDE 3.5.10)
OS:                Linux
Installed from:    Debian testing/unstable Packages

I use digikam for more than two years and never had problems with raw pictures.

Since several days the raw pictures from my Panasonic Lumix LX2 show totally
wrong colours in digikam (thumbnail, normal view and slideshow). Red clothes
get green and green things get red, blue sky gets magenta. White colour (i.e.
snow) is ok.
If I open these raw pictures (F4 button) in edit mode all colours are correct.
Further on exif data for exposure time show wrong (negative) values for these
raw files.

These problems are reproducible.

Raw pictures from my Olympus E500 (.orf) are still correct, the same is true
for all jpg files.

This problem has arised after I had installed ufraw and dcraw, but I did also
some more updates for other packages at the same time which might cause the
problem.

If you need further information about package or library versions, please give
me a note.

ok.

I'm not sure if libraw 0.6.3 is enough to play with Panasonic Lumix LX2. Here,
Alex can give us more information about.

Anyway, i recommend to checkout, compile and install last code of libkdcraw for
KDE3 from svn (future 0.1.8) which include last libraw 0.6.13. I'm pretty sure
that it will work with your Panasonic Lumix LX2 raw files.

Of course remove old libkdcraw before, and after to compile/install libkdcraw
0.1.8, digiKam and kipi-plugins needs to be recompiled.

For more information to know how to checkout code from svn, look here :

I know that an earlier version of libkdcraw worked with LX2 raw files.
I found in my old packagelists libkdcraw3 (debian 0.1.4-2) and in the last
packagelist there are libkdcraw4 (0.1.7-2) and libkdcraw3 (0.1.4-2) both
installed (ii).
I'm a little bit astonished to see libkdcraw4, as I still use KDE 3.5.10.

I will try trhis, but as this is new for me it will take a little time.

Old Panasonic (not .RW2 but .RAW) files does not contains preview (thumbnail)
image.

So, the problem is related to code, which handles preview-less images
(somewhere in digiKam?).

Ok, we talking about preview extraction. And yes, with current code from svn, i
have fixed a little bug about.  It's not relevant of digiKam code here, but
libkdcraw.

So, libkdcraw 0.1.8 will solve it.

woru123, can you send me in private some Raw files sample to test (or a link
where i can download files) ?

Alex,

I don't know if Samsung and Panasonic RAW file is the same format, but it sound
like this comment:

https://bugs.kde.org/show_bug.cgi?id=182611#c10

... is applicable here. Right ?

If yes, woru123, you need to place at the same place RAW and JPEG files taken
with the same shoot, to get a fine thumbnails with RAW files.

Gilles

It sounds like the other bug report, but I think it's different:
First, Samsung S85 raw doesn't conatin any metadata, Panasonic LX2 contains at
least some (much less then jpeg - see attachments).
Second, in my case raw and jpeg files are always placed in the same folder in
the file system.

I tried to follow the instructions, but I did not succeed to build a new
digikam version.
First of all, I didn't have svn and apt-cache search svn brought a lot of
realted packages and I decided to take kdesvn. I then checked out the sources
and changed to the download directory.

Then the problems started here:

wolfgang@cork:~/digikam/libs$ make -f  Makefile.cvs
This Makefile is only for the CVS repository
This will be deleted before making the distribution

./admin/cvs.sh: 632: ./admin/detect-autoconf.pl: Permission denied
./admin/cvs.sh: 651: --version: not found
*** AUTOCONF NOT FOUND!.
*** KDE requires autoconf 2.53 or newer
make[1]: *** [cvs] Fehler 1
make: *** [all] Fehler 2


I'm sorry, but it's the first time I try to compile an application from source.
If there was a debian package available, installing it would be no problem for
me.
