Hi,

i have automatic panoramic image detection enabled with aspect ratio of 2.0 for both landscape and portrait images. I then display panoramic images spanned across multiple monitors.
Sometimes the panoramic image detection seems to fail which causes a panoramic image to be resized and displayed on one monitor only. Logs:

Othertimes it works though.

Hello,
automatic detection of panoramic images is performed with a simple check on image size, if image size is read correctly it is very unlikely this check fails.
Did you notice if the check fails always with the same image ?
Check if there is any file with .gprop extension is present in the folder with the failing images.

Check fails with different images non deterministically. No .gprop file used or present. I will keep an eye on this and write if i have more specific information.

OK i have done further analysis. The problem appears when multiple panoramic images are displayed directly after each other. After displaying a panoramic image spanned on multiple monitors it switches back to displaying individual images on each monitor where one monitor gets a new image and all other monitors get the image that was displayed before the panoramic image came. but when the previous image also was panoramic it gets shrinked to a single monitor.

The problem where the slideshow reverses back to an image that was displayed a couple of seconds ago, was already reported by me in this thread: viewtopic.php?f=9&t=9577 under 1).

Thanks for analysis, I think I found the problem. During next days I will release an update
