http://bugs.kde.org/show_bug.cgi?id=123522         
           Summary: Minolta's RAW files (mrw) aren't show in the view window
           Product: digikam
           Version: 0.8.1
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: gerhard frappe xs4all nl


Version:           0.8.1 (using KDE 3.5.0, Gentoo)
Compiler:          gcc version 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)
OS:                Linux (i686) release 2.6.14-gentoo-r4

While minolta's RAW files are show as thumbnails, they are not viewable in the view windows.  Probably as a result of not reading the dimensions right. The viewer reports 0x0pixels as size.
The thumbnails do work ok, but this could be due to the available thm files.
dcraw reads the files perfectly for what it's worth.
I'll see if I can attach a raw file to this issue for testing.

As RAW files are rather big (almost 9Mb in this case) the system refuses them. Ask if you want a test file. I also have a few Dynax 5d files available if needed.

No need to post a MRW file here, i use minolta camera Dynax 5D...

All work fine here with 0.8.1 using MRW file. Can you post all console messages when you start digikam from a console ?

That I could have thought of myself.. anyhow:

--->8---
[gerhard bull ~]$ digikam
digikam: WARNING: Running dcraw command : dcraw -c -2 -w -a -q 0  
'/home/gerhard/Fotografie/Archief/Werk/10260312/pict0201.mrw'
0: No such file or directory
/home/gerhard/Fotografie/Archief/Werk/10260312/pict0201.mrw: unsupported file
format.
digikam: WARNING: Not a raw digital camera image.
--->8---

Double checked the file, it does exists (as it shows a thumbnail, but
nevertheless). dcraw was version 6.31 (last stable) and is now 8.03 Both give
the same error.

To add to the fun I get the same error when clicking on a Canon powershot G3
CRW file:

--->8---
digikam: WARNING: Running dcraw command : dcraw -c -2 -w -a -q 0
'/home/gerhard/Fotografie/Archief/Werk/2005-07-10/CRW_3507.CRW'
0: No such file or directory
/home/gerhard/Fotografie/Archief/Werk/2005-07-10/CRW_3512.CRW: Not a TIFF
file, bad version number 26 (0x1a).
--->8---

after which the image IS shown..  After a little experimenting it seems that
the space between the -q and the 0 isn't liked by dcraw.

dcraw -c -2 -w -a -q 0
'/home/gerhard/Fotografie/Archief/Werk/2005-07-10/CRW_3507.CRW'

complains with the 0: no such file or directy while

dcraw -c -2 -w -a -q0
'/home/gerhard/Fotografie/Archief/Werk/2005-07-10/CRW_3507.CRW'

doesn't.

Hope it makes some sense..

Gerhard

Right. I will take a look about this dummy space. thanks for the report.

The -q 0 option is require for the quality decoding levels to limit image decoding time.

The space between q and 0 from "-q 0" dcraw option is require to preserve compatibilty between dcraw < 0.8.x  and last dcraw release. The space is not a problem :

With "dcraw" v8.03 :
dcraw -2 -w -a -q 0 MINOLTA-DYNAX7D.MRW ==> work fine
dcraw -2 -w -a -q0 MINOLTA-DYNAX7D.MRW ==> Error : Non-numeric argument to "-q"

With "dcraw" v6.35 :
dcraw -2 -w -a -q 0 MINOLTA-DYNAX7D.MRW ==>  Warning : "0: No such file or directory" ... but the file is decoded !
dcraw -2 -w -a -q0 MINOLTA-DYNAX7D.MRW ==> work fine

SVN commit 520608 by cgilles:

digikam from trunk : Raw File decoding bugfix.

This is the most stupid bug to found : always enable raw decoding quality setting to use with dcraw in 0.9.0 BY DEFAULT ! ... else if you toogle between 0.8.x serie and 0.9.0, you will have a 0x0 image size into Image Editor...

For as well the unstable (9.0 yesterday) as the stable 8.0 svn version it's a
no.
I installed the svn stable version as per info on the website.

output:

----8<----

digikam: WARNING: Running dcraw command : dcraw -c -2 -w -a -q 0
'/home/gerhard/Fotografie/Archief/Werk/10360307/pict0131.mrw'
0: No such file or directory
/home/gerhard/Fotografie/Archief/Werk/10360307/pict0131.mrw: unsupported file
format.
digikam: WARNING: Not a raw digital camera image.

----8<----

Still the same problem. It sees the 0 in -q 0 as the filename. This is with
dcraw v5.86.

Found an old dcraw which didn't support mrw files yet on the system.  Together with your patch to fix the -q 0 the problem is solved.
Thanks for the support!

Sounds good (:=)))...

Note that i have annoted in README file that digikam need dcraw 8.x release to work properly.

Thanks for the report.

And that's what I use now again (and how I found out about the old version
hanging around.. The versionnumber hadn't chanced..)
