PDF Merging Issues

[bharat619]

I am trying to merge 2 PDF's.
The first PDF does not have link. But the second PDF has links. By links, I mean that when I click on them it navigates to other part of the PDF.
The links works fine if I don't merge the PDF's. But when I merge the PDF, I loose the ability to link to other part of the PDF.

I am using the CLI, hexapdf merge a.pdf b.pdf output.pdf

Here b.pdf file has the links.

A thing to note:
If I do something like hexapdf merge b.pdf a.pdf output.pdf, the link works fine. But now I loose the order.

Am I missing something or doing something in a wrong way?

BTW, this is an awesome gem.

Thanks for the report!

You are not doing anything wrong. The way the hexapdf merge command currently works doesn't preserve that information. I will see how to change that.

By links, I mean that when I click on them it navigates to other part of the PDF.

@bharat619 Are those links on the pages themselves or do you mean the outline feature of a PDF that shows in an extra part of the PDF viewer?

Used https://8gwifi.org/merge-pdf.jsp for PDF merge with ordering it works

@anishnath That is okay but you will need to do that manually and can't do it automatically like with HexaPDF. It might also be a problem with sensitive documents that one doesn't want to share with a website.
