Thanks for providing the steps to reproduce as well as the sample file!

I was able to reproduce the same result and I suspect the redaction is removing the group of paths.


However, it does not explain why the outlines of the squares are left. I will have to submit this for analysis and get back to you when I have more information.


Thanks for your reply.
All right.
I look forward to hearing back from you.

Best Regard.


Thank you for your patience with this issue. The document you provided has gradients defined as shading objects (this is part of the PDF standard). As part of the redaction process, shading objects are removed due to security implications.

We are looking to see if this behavior can be changed in the future.


Thank you for looking up.

All right.

Sorry, I have a few questions.

Are there any conditions other than shading?

Is there a workaround?

Is it always NG if there is a shading?

I want you to investigate files that may not have shading, however, this file can’t upload here.
Therefore, please email me.
