The problem is that the MergeFileList is being used.
At the same time, it is impossible to do something with the files before merging.
And for reference, the described "combine" commands do not fix it at all.
After merging the layers are only on the first page, they are lost on the rest.
So I am not using new versions yet, there are no useful fixes. ]]> Tue, 02 Feb 2021 18:52:48 +0000 http://www.quickpdf.org/forum/merge-pdf-with-layers_topic3875_post15578.html#15578 http://www.quickpdf.org/forum/merge-pdf-with-layers_topic3875_post15536.html#15536 Author: Ingo

Probably need to work directly with OSG .But there is no combination function for OCG .Maybe there is a solution for this OCG probleml?

Regarding OCG you'll find a lot of interesting informations inside the developer guide...

Try this search:
https://www.debenu.com/docs/pdf_library_reference/Search.php
...and insert OCG in the search field.
The search result will be large enough - perhaps there's something which feed your needs.

Hi Sergey,

"combine" is the key ;-)
After Load of each pdf try...
NormalizePage:
https://www.debenu.com/docs/pdf_library_reference/NormalizePage.php
CombineContentStreams:
https://www.debenu.com/docs/pdf_library_reference/CombineContentStreams.php
...and then do the concatenation of the files.

Cheers and welcome here,
Ingo

Hello everyone!

I am using QuickPDF V18 under a trial license.
I am trying to combine several PDF files into one.These PDF files have layers.When merging, the layers remain only in the first file, the layers disappear in the rest.Is there some way to fix this?

I will be grateful to everyone!
