I also installed latest Digikam on my Mac Studio M1 Max. You can find the
screenshot in the same GDrive folder. Here works.

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.

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?

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.

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:

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
