[Bug 250511] New: TIF Image appears corrupted in Digikam

https://bugs.kde.org/show_bug.cgi?id=250511

           Summary: TIF Image appears corrupted in Digikam
           Product: digikam
           Version: 1.2.0
          Platform: MacPorts Packages
        OS/Version: OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.2.0 (using KDE 4.4.5)
OS:                OS X

I have an image, so far I have only found one, that looks corrupted in Digikam.
Opened in Okular, Gimp, etc. the image looks fine but in Digikam it looks like
it has been cut into misaligned stripes. I have only found the one affected
image but their could be more.
Thumbnails, Preview, and Image Editer seem to be affected. But the Kipi OpenGL
Image Viewer is unaffected. Strange?

Reproducible: Always

Steps to Reproduce:
1) Import image into Digikam
2) Open with Viewer or editer

Actual Results:  
The image looks like it has been cut into misaligned stripes.

Expected Results:  
That the image would look as it does it Okular, Gimp, or any other image view I
have tested.

I used LightRoom 2 in the past to manage my collection and this image is from
that time, I wouldn't be at all surprised if the problem has something to do
with LightRoom - so many problems do!

words and all that.

I recommend to test with digiKAm 1.4.0 where some patch have been applied to
TIFF loader.

Also, libExiv2 is an important component used by digiKam to handle metadata.
Exiv2 0.20.0 include some improvement about TIFF parsing. Check this library on
your computer.

Finally, libtiff, which is used to load tiff image data. Check if you use the
last stable release.

It can easily be reproduced. Obviously, individual stripes are mirrored
individually. This image must use some peculiar format or feature of the TIFF
specification.
Digikam is susceptible to such problem because we do not use the simple default
routines from libtiff, but need to support more features, like 16bit or
cancellation of loading, so we must use the lower level API.
