 Topic: Merge PDF with LayersPosted: 12 Jan 21 at 3:46PM |

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!

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 Reference guide: https://www.debenu.com/docs/pdf_library_reference/FunctionGroups.php Developer guide: http://www.debenu.com/docs/pdf_library_developer_guide/foxit_quick_pdf_library_15_developer_guide.pdf |

Thank you so much Ingo, for your answer!
My mistake is that I wrote "Layers". After reading the documentation, I realized that the correct term is OCG (Optional Content Groups) Edited by ventumsoft - 13 Jan 21 at 2:20AM |

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. |

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. |
