            Bug ID: 356080
           Summary: digiKam does not open preview for LZW non-stripped
                    TIFFs created by ScanTailor
           Product: digikam
           Version: 4.14.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Albums View
          Assignee: [hidden email]
          Reporter: [hidden email]

Hi,

I process scanned images with ScanTailor, which outputs TIFF files with LZW
compression (B&W, Colour).

digiKam shows only the thumbnail and fails on preview. On CLI, it complains
about missing support for non-stripped images:

digikam(8658)/digikam (core) Digikam::ThumbnailCreator::createThumbnail: Cannot
create thumbnail for  "/srv/Photos/Testing/Bugs/ScanTailor-LZW.tif"
digikam(8658)/digikam (core) Digikam::ThumbnailCreator::load: Thumbnail is null
for  "/srv/Photos/Testing/Bugs/ScanTailor-LZW.tif"
digikam(8658)/digikam (core) Digikam::ImageInfo::fromLocationAlbumAndName: No
itemShortInfo could be retrieved from the database for image
"ScanTailor-LZW.tif"
digikam(8658)/digikam (core) Digikam::TIFFLoader::load: TIFF loader: Cannot
handle non-stripped images. Loading file
"/srv/Photos/Testing/Bugs/ScanTailor-LZW.tif"




Reproducible: Always




There is a similar bug (RESOLVED/FIXED) a few years ago:
https://bugs.kde.org/show_bug.cgi?id=241418.

All other viewers I use can handle it correctly (ImageMagick, Geeqie, Eye of
Mate, PhotoPrint, XnView, darktable, GIMP). ShowFoto also displays only a
thumbnail and no image.
