The Problem

I understand that the efficiency bug was supposedly fixed back in version 37.1. However, I'm running version 38.0, and I'm still encountering the issue. There was a previous hypothesis that it might be due to only a single image being compressed within the file. The compression process runs indefinitely and yields no results.

@stinger679
Does the PDF compression process complete despite the warnings, or does it run indefinitely in version 0.41.0?

[stinger679]

@Abdurrahman-shaikh

indefinitely processing

[Abdurrahman-shaikh]

@Frooodle
It looks like the issue might not be with the PDF file itself but rather a problem with qpdf. Here's the related issue:qpdf/qpdf#1292.

I've tested this error locally and observed the same behavior. I suggest ignoring this issue for now and proceeding with the code as is.

Would it be possible for me to work on this?

[Frooodle]

@Abdurrahman-shaikh Sure!
