Incorrect display of PSD thumbnails

Unread postby photoken » 19.04.2012 03:55

Using PhotoSafe 3.40
Win7 x64

When a PSD file uses layers, the PhotoSafe display is incorrect. In my editing program (PSE), I have used the "Maximize PSD Compatibility" option.

This is the PSD thumbnail displayed in the PSE Organizer:

I suspect HPS shows only first layer of the PSD file. I suspect that PSE knows more about PSD files than we do. That would be hard to fix, I am afraid.

That's unfortunate, and a show-stopper for me because PSD files are what's generated by my editing program (PSE).

If it's any help, the author of XnView has made available for free their graphics library for developers to use for displaying images of over 100 formats:

Thanks, and XnView shows PSD correctly? Can you send us a couple of such PSD files for tests?

In some cases, no, but I did some experiments and found the problem: if a PSD file includes a saved selection, the thumbnail is displayed incorrectly. If the PSD file does not include any saved selections, XnView displays the thumbnails correctly. Apparently a saved selection is being used by the thumbnail as an alpha channel, which screws up everything.

I'll be following up on this with the author of XnView.

However, PhotoSafe does not display thumbnails for PSD files that do not have saved selections, and XnView does correctly display thumbnails for those files. I will be e-mailing you a sample of one of these PSD files as "PSDfile.zip".
