[Bug 286373] New: DNG don't get filtered as raw

[Andreas T. Ege]

https://bugs.kde.org/show_bug.cgi?id=286373

           Summary: DNG don't get filtered as raw
           Product: digikam
           Version: 2.3.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: RAW files management
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           2.3.0 (using KDE 4.7.3)
OS:                Linux

If I filter image view by mime type filter --> no raw files (names translated
back from german, so actual english name might differ), it sometimes doesn't
filter out the dng images as raw, and they show up together with the jpg and
png, which risks deleting them as duplicate images, besides being an irritant.
They still are proper raw, gimp alone can't handle them, ufraw does, but for
some reason digikams mime filter interprets them as non-raw.
The other way round, if I filter for --> show dng, those pictures don't show
up.

I'm not sure how to reproduce this problem, I think it happens after renaming,
but it always only affects a number of random dng, never all.
It's been happening to me at least since DC 1.9.

I thought I had reported the bug before, but can't find it in the bug tracker.

Reproducible: Sometimes

Steps to Reproduce:
Not sure, I think (batch) renaming plays a role, but can't confirm at moment.

Actual Results:  
dng images show even filter is set not to show raw images

Expected Results:  
dng images not to show.

Do you use versionning over your DNG ? For ex, do you open DNG to editor and
convert it as JPEG, as new version ?

No, I don't. I only use digikam for tagging, commenting, geotagging, renaming,
..., basically for organizing.
For actual image manipulation I use ufraw for raw and gimp for everything else.
For batch changing file format or image sizes I tend to use ImageMagick.
I usually have the dng associated either with jpg (from the cameras dual mode
raw+jpg) or png if I processed the raws with ufraw and gimp.

I have the same problem with .CR2 files. There seems to be no special pattern.
From one precise moment, some .CR2 pictures ceased to be recognized as RAW, and
are listed as if they were JPEG files.
Some of these photos are renamed in Digikam, but I don't think it is always the
case.

My picture are generally derawtised in another program (Rawtherapee in the
past, Darktable more recently).

The new grouping function seems to complicate the issue, as it doesn't seem to
identify RAW pictures properly, and they are not displayed in any group.

Had the problem with a bunch of dng again: after batch-renaming 172 images (86
dng and 86 jpg) 13 of the dng won't be recognized as raw anymore.
Under image properties, type is ADOBE-DNG, dimensions and colour mode unknown,
depth of colour 0bpp. Dimension values displayed under the image is 0x0 (0.00
Mpx), with a size of 16.2 MiB.
Restarting digikam doesn't change things, nor does F5.
Other programs like geeqie still recognize dimensions.

What did solve the problem here (as a workaround), is re-reading the metadata,
after that the image dimensions were recognized and the image correctly
identified as dng and raw.

This scenario looks as if the file properties from the filesystem are read
correctly, but not the metadata. One could think that the renaming happens in
between, but I'm not sure why a file would be rescanned before the rename. In
case it happens though, we'd need to take precautions.

In 2.4.0 we have replaced the file monitoring code, now files will be rescanned
after they have been closed for writing.
Is someone still able to reproduce this problem after batch renaming with
2.5.0? Then I'd like to investigate further.

Hi,

I use 2.6.0 on Linux Debian, and have the same problem.
608 JPEG and 98 DNG in an album.
I renamed all the files using Digikam. I included the "e" option, example :
###[e,652,1]_[file]

I attached a tar file ("screenshots") to illustrate these steps :

Step 1
Two filters : text = "dng",  and MIME type = "not RAW"
See 286373_01_filter.png

Step 2
286373_02_bad_images.png
We see that some images are shown, and we see that "image properties" for the
selected image are empty, exactly as in AT's post dated 2011-12-25 16:34:10 UTC

286373_03_exif_good.png  : we see that EXIF data has not the same problem as
"image properties".

Step 3.
I execute a "touch 495_IMCD5963.jpg" in a shell, to force digikam to re-read
datas from the file.
After that, I have to select "all files" in MIME filter to see again the file
(it is the expected behaviour), and the images properties are correctly
displayed :
286373_04_after_touch_without_filter.png


Note that the problem is NOT specific to DNG files. I have the same problem for
29 JPEG files.
I used digikam editor for some JPEG, but surely not for the 29 files.

I checked quickly the 29 files, and I am quite sure that I didn't perform any
specific action on these files.

I hope it can help.
Thanks in advance.

Just had the problem again, some dng are not recognized after batch renaming
dng + associated jpg/ png.
Re-reading the exif info of the dng lets digikam recognize them again.

digikam 4.4.0 and sabayon linux.

Oh, and kde 4.14.3,

and as before, it's not all dng, only the odd one in between, without any
obvious pattern to me.

Hi there,

sorry for the long delay. First the Sabayon repos didn't catch up with digikam
versions, and then I didn't have a suitable large No of photos ready. ;-)
I've renamed a few hundred dng/ jpg or png pairings now, and it seems it's
resolved with digikam 4.12.0.
Thumbs up. :-))
