cr2 files problem - only a green coloured fraction visible

[Dr. Martin Senftleben]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

I have digikam 1.2.0 on KDE 4.3.5 running, system is (now) LinuxMint 8
Helena with Gnome. All 64bit.
Now, when I want to view cr2 files in the editor, it shows only a
fraction of the image and that is also only in green, as if someone
painted green over a b&w picture. Doesn't look good. Also converted
images from the cr2 file look like that. I guess it's a problem in the
KDE and I have to wait for the next version (I was already further,
some might remember, when I still used OpenSuse, but I got too many
problems with it), but I just wanted to make sure. I know that
something like this was discussed earlier, but as it didn't affect me,
I didn't bother...

Thanks for any hints, otherwise I'll just be patient and hope for the
best... ;-)

Are other programs working as expected (like ufraw, rawtherapee ...)?
I have some strange results if I use non default colour profiles in
showfoto which I don't have in ufraw.

No, it seems it's the same problem with ufraw. and it's pink, not
green (also in digikam). It's exactly the same like in digikam. I have
prepared a snapshot to see:
http://www.drmartinus.de/downloads/strange_raw.png. Maybe that gives
an idea?

CR2 files from which camera?  As far as I know, 7D and 550D RAW files can't be read in digikam yet.

This is the 7D. However, I could work with cr2-images  without
problems before I switched to LinuxMint. So digikam should be able to
handle it. And since ufraw shows the same behaviour, I suspect another
reason, but I have no clue unfortunately...

I've tried to open a 7D cr2 file in every release of digikam starting back with 1.0, so far with no success.  The latest alpha of Rawtherapee opens them, but the software is still quite unstable.

Of course, there's no problems with cr2 files from older cameras (mine is a 400D).

What if you check the version of UFRaw (or libkdcraw, which is used by
digiKam) between your previous and current setup?

BTW UFRaw tells you it cannot handle camera white balance presets.

Not sure what you mean by open 7D cr2 files but I can display them fine in Digikam - never had a problem since I recently got the camera. I can put them onto the "light table" and view them. Haven't really tried editing them in Digikam as I do that in photoshop. I'm running v1.1.0 as the latest hasn't hit the depository (portage) for Gentoo yet, which is what I run. (I could grab it from an overlay but things are pretty usable now for me).  /jim

I checked the version of libkdcraw, but I can't compare to the
previous setup. I'm however pretty sure this is an earlier version
than I had on my previous setup. Now it's 4.3.5.

Which Canon camera are you using? You almost certainly need to update
dcraw. Which means an up to date version of ufraw (0.17) and kdegraphics
for digikam.
