PDF images do not display in Zotero viewer but do display in Preview.app

rebelprincenyc · September 15, 2022

I have a downloaded google book that has images which display when I use the Preview app but not when I use Zotero reader on my iMac. On page 30 of the file linked below, I see only a blank space where the image should be in Zotero reader. If I click "show file" and open the same file in Preview i can see the image on page 30. I have encountered this problem with other books dowloaded from Google as well.

Can you see the image if you open the PDF file with PDF.js online viewer?

No, the image does not show up when I open the PDF with the Firefox viewer. but it does show up if I open it with the Chrome viewer. I don't know how to open a pdf with the pdf.js viewer but it looks like opening it in firefox is the same interface as the one you linked to. Is there a reason that PDF.js would have trouble displaying certain images?

Not much we can do at the moment. We have to wait until PDF.js fixes that. Most likely there is something non-standard with the those images. I saw similar cases before.

Ah, ok! It’s a pretty big issue for me; it has cropped up in dozens of PDFs downloaded from Google Books. Hope they fix it soon. Is there a way to submit a bug report to Mozilla?

You can try reporting it here.

Is the RTL language rendering problem inherent in pdf.js or zotero?

I am asking because so I can plan accordingly if there is no chance of it being resolved until Zotero 7.
