Steps to reproduce:

1. Go to this Wikimedia Commons page: https://commons.wikimedia.org/wiki/File:Vida_y_escritos_del_Dr._Jos%C3%A9_Rizal,_por_Wenceslao_Retana.pdf
2. Select "Original file", causing Firefox to load said PDF
3. Went to page 7 and page 563

Actual results:

In page 7, there is a blank space below RESPECTIVAMENTE.
In page 563, nearly the entire page is blank, save some text on the right side, which serves as the caption for the "hidden" image.

Expected results:

In page 7, there should be an image below RESPECTIVAMENTE, displaying the logo of the printing press.
In page 563, there should be an image of a bill and a stamp.

The Bugbug bot thinks this bug should belong to the 'Firefox::PDF Viewer' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hi Jan,
thank you for taking the time to submit this bug report.
I was able to reproduce on Windows 10, on Firefox Nightly 94.0a1 (2021-09-20) (64-bit) version and Release 92.0 (64-bit) version, as described in actual results. Based on this I will mark each respective flag as affected and set the severity.

I let the component in order to get the dev team involved, but if it's not relevant,
'Firefox-PDF Viewer' team, please feel free to change the component if this is not the appropriate one.

Jerónimo.

Change the status for beta to have the same as nightly and release.
For more information, please visit auto_nag documentation.

I can confirm this bug with the nightly build.

It seems to be a problem with the embedded JPX image.

The console out put shows:

These COD options aren't supported:

:jrmuizel, do you know someone who could help to implement that stuff ?

Calixte, I don't really know anyone who's familiar with jpeg2000 to suggest. If it's important we could come up with someone though. Perhaps one of the Outreachy people would be an option?

I implemented one of the easy options for fun. Maybe I'd look at the others when some free time shows up.

terminationOnEachCodingPass is probably a good one to implement next

:jrmuizel, would you mind to make a PR with your patch in pdf.js repo ?
