Can you provide some PSD image files to test Gilles Caulier Or better, a documentation of newer PSD format? Hum, PSD is a proprietary format from Adobe. Ther is no doc avaialble, only reverse engineering work, as ImageMAgick PSD loader for ex : http://trac.imagemagick.org/browser/ImageMagick/branches/ImageMagick-6.6.6/coders/psd.c There is also FreeImage loader : http://freeimage.cvs.sourceforge.net/viewvc/freeimage/FreeImage/Source/FreeImage/PSDParser.cpp?revision=1.13&view=markup A beta libpsd exist too, as beta : http://sourceforge.net/projects/libpsd/ The KDE/QImage image loader (8 bits) can be also adapted to digiKam: http://websvn.kde.org/trunk/KDE/kdelibs/kimgio/psd.cpp?revision=755636&view=markup Gilles Caulier digiKam do not have code to handle PSD image. It's delegate to KDE image IO component. Gilles Caulier (In reply to caulier.gilles from comment #4) > digiKam do not have code to handle PSD image. It's delegate to KDE image IO > component. Hi Gilles, also this one should be should be solved by MR !56 (https://invent.kde.org/frameworks/kimageformats/-/merge_requests/56) Mirco. Hi Mirco, The problem to support 16 bits PSD images is partially fixed with KF5 5.95. Look my screenshot of digiKam 7.8.0 under macOS compiled with KF5 5.95: https://i.imgur.com/hh9zX0H.png I generated a 16 bits PSD using integer encoding with GIMP. Thumbnail is ok. I generated a 16 bits PSD using float encoding with GIMP. Thumbnail is broken. Best regards Gilles Caulier Hi Gilles, (In reply to caulier.gilles from comment #6) > I generated a 16 bits PSD using integer encoding with GIMP. Thumbnail is ok. > I generated a 16 bits PSD using float encoding with GIMP. Thumbnail is Interesting... because Photoshop does not allow to save a 16-bit float PSD. Anyway, it opens the one saved by GIMP. I'll fix the kimage-formats plugin ASAP. Mirco. Hi Gilles,

I did some test under Windows. I saved a grayscale 16-bit float using GIMP and the current version of kimage-formats plugin loads it without any issues. Another info is that the internal data are not float but are converted to 16-bits integer during the save operation by GIMP: this makes sense because PSD format does not have an option to discriminate if the data are float or integer (8/16-bits data are always integer, 32-bits data are always float).
Can you attach a PSD sample which give you the problem?
Hi Mirco, I shared files to you on my GDrive account. You will receive an email with the link on your gmail. Gilles Hi Gilles,

I tested your images on Windows with latest version of PSD plugin and on my Debian unstable that uses KF 5.94. I also shared the project I used on the same folder on GDrive (there is also a screenshot).
I think the issues you have is not related to PSD plugin.
PS: I also added a screenshot of DigiKam 7.7.0 installed on my debian.

I also installed latest Digikam on my Mac Studio M1 Max. You can find the screenshot in the same GDrive folder. Here works.
Hi Mirco, You are right. I restarted digiKam 7.8.0 on my macOS and now all thumbnails are properly displayed. So the problem is really fixed. Thanks... Gilles |
