Description Ken Sharp 2009-11-17 00:38:39 UTC 
The output of pdfwrite currently does not preserve any optional content
contained in an input PDF file. We need to add the possibility to do so.
Comment 1 Alex Cherepanov 2009-11-17 05:53:46 UTC 
See bug 690633 for a simple OC handler that just skips invisible content.

Sample files with invisible layers include: comparefiles/BFAX35P5.pdf
and sample files attached to the bugs 689289, 689716, 689924, 690633.
Comment 2 Alex Cherepanov 2009-11-17 20:40:07 UTC 
One more file with OC is comparefiles/Bug689290.pdf
The file is identical to the sample file of the bug 689289.

implements Optional Content preservation in pdfwrite, as documented in this commit:

I checked the files from the bugs listed in comment 1 and 2 and these now have optional content preserved in the output.
