[Bug 241418] New: LZW compressed TIFFs from RawTherapee are won't display

[Michal Thoma]

https://bugs.kde.org/show_bug.cgi?id=241418

           Summary: LZW compressed TIFFs from RawTherapee are won't
                    display
           Product: digikam
           Version: 1.2.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.2.0 (using KDE 4.4.2)
OS:                Linux

Digikam can't display LZW compressed TIFFs from the RawTherapee. This is
strange because, digikam normally handles LZW compressed TIFFs from other
application. Anyway RawTherapee LZW compressed tiffs are also displayed
correctly in all other application like Gwenview, Gthumb, Photoshop, Gimp.

There is already open bug in RawTherapee issue tracker:

http://code.google.com/p/rawtherapee/issues/detail?id=107

Right now we can't decide if the problem is in digikam or in RawTherapee
output.

Please find example image in attachment.

Reproducible: Always

This also happens for LZW compressed grayscale tiffs created by irfanview
(win):

digikam(8409)/digikam (core) Digikam::TIFFLoader::load: Can not handle image
without RGB color-space:  3

SVN commit 1137991 by jwienke:

Also enable tiffs with palette. Could not find any problems with a quick test.
Please test that this solves the original issue.

Oh, here is the sample image for this issue:

http://michal.thoma.cz/digikam/lzwtiff8.tif

(RawTherape LZW compressed 8 bit RGB tiff)

I'm bit shocked that it's not here, I thought I uploaded that days ago...

When looking at error console it states:

digikam(28314)/digikam (core) Digikam::TIFFLoader::load: TIFF loader: Cannot
handle non-stripped images. Loading file
"/home/michal/Fotoarchiv/Temp/lzwtiff8.tif"

So I believe it's not same issue as with grayscale lzw images.

I have no idea what is stripped or nonstripped TIFF.
