PDF export - images as black boxes

Hello everyone, I have a question concerning the export to PDF. When I do the export of my tropy list including the images, many (not all) of them appear as black boxes. This seems to happen randomly, as it sometimes occurs to a selected data set, but not when exporting the entire list and vice versa. I would be happy if you could help me. Thank you!!

It sounds like this could be an error where individual images are not loaded (or are not loaded in time) during the export process. Can you tell us what operating system version you’re using? The print/pdf stacks work differently on each platform.

If you notice additional details it could help us figure this out. For example, if it the same photo always fails, I would guess that there’s an issue loading that specific photo. If it happens randomly, as you say above, and given photo sometimes works and sometimes does not I would guess that it’s a timing issue. A timing issue should be more likely to happen if you’re exporting a larger set; less so if exporting a smaller set or even just a single photo.

If it’s down to timing, there is currently an arbitrary timeout (two seconds) – if all images have not reported as being loaded the PDF conversion will continue. It’s possible that this is just too short in your case. Again, this is more likely to happen if you export lots of photos together or if the photos are very big, but maybe we just allow for a little more time there.

If the images are big it would also help to make sure you have the option ‘Optimize photo size and quality’ enabled in the preferences.
