[Bug 259182] New: Jpg image shows corrupt in view and edit mode

https://bugs.kde.org/show_bug.cgi?id=259182

           Summary: Jpg image shows corrupt in view and edit mode
           Product: digikam
           Version: 1.6.0
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Image Editor
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.6.0 (using KDE 4.5.4)
OS:                Linux

I have a single image, which I will attach, which shows corrupt in Digikam view
and edit modes. It appears like the pitch is being calculated incorrectly as a
comb pattern appears over the image. It shows correctly in other photo software
including Gimp so I don't think the image is corrupt. I took the photo as a RAW
on a Sony DSLR and processed it in to a JPG in Adobe Photoshop in Windows,
before saving it out as a greyscale jpg image.


Reproducible: Always

Steps to Reproduce:
1) Load the attached image with digikam.
2) Open it in either 'edit' or 'view' mode.


Actual Results:  
You will see the corrupt image as described.

Expected Results:  
The image should look the same as when it is opened in other packages such as
Gimp.

OS: Linux (x86_64) release 2.6.35-23-generic
Compiler: cc
Ubuntu 10.10

tar of the test image

I've attached a tar of the test image that can be downloaded, just in case the
bug tracking server has manipulated the jpg when I uploaded it. Try the version
in this archive.

showfoto svn (1.7.0) with libjpeg 8.0 : no problem...

Showfoto with libjpeg 8.0 running under mandriva 2010.1. No problem to open
your test jpeg image.

I suspect a broken install of your libjpeg on your system.

Can you give us more information about libjpeg package installed on your
system, as description, changelog, etc...

Do you have more than one libjpeg installed on your system ?

I think you may be right, although I haven't done anything special to get that
version of libjpeg on to my system. In synaptic I see two versions of libjpeg.
The one I have installed is libjpeg62:

libjpeg62:
  Installed: 6b-16.1
  Candidate: 6b-16.1
  Version table:
 *** 6b-16.1 0
        500 http://gb.archive.ubuntu.com/ubuntu/ maverick/main amd64 Packages
        100 /var/lib/dpkg/status

There's another called libjpeg8

libjpeg8:
  Installed: (none)
  Candidate: 8b-1
  Version table:
     8b-1 0
        500 http://gb.archive.ubuntu.com/ubuntu/ maverick/main amd64 Packages

Apparently digikam is marked as dependent on libjpeg62:

I have tried installing libjpeg8 alongside libjpeg62, however digikam still
seems to use libjpeg62. I can't uninstall libjpeg62 because most programs seem
to depend on it.

It's a compile time dependency. to use libjpeg 8.0, digikam need to be
recompiled...

I'm curious about this too as I have about the same system (Kubuntu 10.10, KDE
4.5.4) as Graham but can't reproduce the bug with the testimage.

Hi again,

After mentioning it to Philip Johnsson, the package maintainer, he noted that
he does not see the same bug and he has the same install as I do (albeit KDE
whereas I use Gnome). This indicated that it may not be a build issue but some
kind of configuration issue on my machine. As a test I tried converting the
test image to a PNG using Gimp, and found that the corruption still occurs. The
image shows fine in Gimp, Image Viewer, and every other application I have
tried, but not in Digikam. I cannot attach the test image as PNG because the
server will only allow attachments of 1MB unfortunately.

Regards
Graham

I believe I have a lead. The bug only occurs when you switch on colour
management.

We need to know the full CM config. Also all ICC profile files used in your
settings...

No problem.

I'm using Adobe RGB as my working space and sRGB as my monitor profile, though
it also occurs with sRGB as the working space.

Is there a settings file located somewhere that I can attach?

I can reproduce. I suspect it indeed happens in color conversion: The image is
grayscale and has a grayscale embedded color profile. I am sure our code has so
far only been tested with color images.

SVN commit 1206683 by mwiesweg:

In our DImg, the input format is always BGRA, never grayscale or CMYK.
I cannot really see if the test grayscale image in 259182 is
properly color managed, but I hope lcms is clever enough to handle
applying a grayscale profile on an BGRA image.
