[digikam] [Bug 480606] Digikam git doesn't display thumbnails from tif images cropped with Rawtherapee
https://bugs.kde.org/show_bug.cgi?id=480606 --- Comment #25 from maderios --- Yes, I use sidecars, I never use IPTC and EXIF. Cameras creates EXIF but I don't need this kind of metadata. May be I'm wrong but I think converting IPTC to XMP is useless because Digikam never ends recreating interaction issue between XMP and EXIF/IPTC. I tested it with 11 images this way: In images test directory, I deleted .xmp files then, I deleted all images metadata in this directory : find . -type f -iname '*.tif' | xargs exiv2 -v -k delete After launching Digikam, I see metadata have disappeared, good. Then I tagged my 11 images normally, with XMP settings, only one tag 'animaux' In metadata editor, all is right in XMP keyword section but i see tag/keyword 'animaux' is present in IPTC section. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480606 --- Comment #24 from Maik Qualmann --- I'm guessing you're using sidecars. There is an interaction between XMP and EXIF/IPTC. Check out the XMP conversion table: https://exiv2.org/conversion.html To prevent this, you would have to deactivate the sidecar.

https://bugs.kde.org/show_bug.cgi?id=480606 --- Comment #23 from maderios --- I see the new BQM tool doesn't remove all IPTC metadata To reproduce: select tiff image In BQM choose remove image IPTC metadata "completely" remove IPTC In metadata editor item -> edit metadata -> IPTC -> keyword One keyword tag is still there. I tested with other images, same issue, each time, one keyword is not deleted (only one each time) -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480606 --- Comment #22 from maderios --- Because the problem comes from IPTC, not using IPTC would be a good thing but i did not find a way to disable it. Is it possible? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480606 --- Comment #16 from Maik Qualmann --- Another fact is that if programs like Gimp or Rawtherapee do not update the embedded preview image, you think you have removed sensitive information with a crop, but it is still in the preview image.

https://bugs.kde.org/show_bug.cgi?id=480606 --- Comment #12 from Maik Qualmann --- Do not you understand? digiKam uses the embedded preview image in the TIFF image, if it exists, to create thumbnails faster. Rawtherapee removed this thumbnail in older versions, so digiKam created the thumbnail from the full TIFF - all good. Now the “old” preview image remains in the TIF, which of course we then use and the display is not correct. So either Rawtherapee removes the preview image as before or saves a correct one.

No issue with two file managers, Dolphin 23.08.4-1 and Pcmanfm-Qt 1.4.0. They display cropped cropped file/ tiff thumbnails normally.

https://bugs.kde.org/show_bug.cgi?id=480606 --- Comment #10 from Maik Qualmann --- I have Rawtherapee 5.9 here, this version removes the IPTC preview, so the thumbnail in digiKam is correct. If the Rawtherapee git version keeps the IPTC preview but does not update it, that is a bug. Maik -- You are receiving this mail because: You are watching all bug changes.

To be clear: I can open both files and display thumbnails too but Digikam doesn't display image cropped thumbnail, it displays two same thumbnails, as if one of these images has not been cropped. I tested with Rawtherapee 5.9, issue is not present, cropped image thumbnail is displayed normally. Something has changed with Rawtherapee git version.

Now digiKam uses the preview image for performance reasons if it is available. Maik -- You are receiving this mail because: You are watching all bug changes.
