Help: Copy all page content to a new pdf file

[bn3t]

Hi,
I want to merge pages from 2 pdfs files into one. I already have such a tool that I wrote in GO but I want to rewrite it in Rust using lopdf.

This is the state of where I am: https://gist.github.com/bn3t/1508f3526bc4ca894f818182bf23e602. It tries to copy page 1 of the input document to the doc document but still produces a white page.

Would you be so kind to indicate the step needed to achieve this?

There are many objects related to pages, in Resources. To merge 2 pdf files, merge all the objects, then rearrange trailer, Catalog and Pages objects.

Hi i'm interested in this did you achieve @bn3t ?

[bn3t]

Hi @yodatak, no I didn't make any progress on this. In the meanwhile, I still use a small tool I've wrttten in Go with Unidoc : pdfmerge

@J-F-Liu is this easy to do? can you provide some tips or some sample code?

[J-F-Liu]

I use pdfunite to do the job.

[edulix]

I meant if it is easy to do with lopdf library, although thanks for the recommendation.

[J-F-Liu]

It is possible, but need to sort out a detailed algorithm.

[bn3t]

It seemed far fetched for me to do it with lopdf. I still use the tool I wrote in go and does exactly what I needed: /~https://github.com/bn3t/pdfmerge.

@bn3t @edulix actually I did this.

I created a PR #117 with all necessary code.

Once @J-F-Liu will merge it, you'll able to this with this Rust library.

Can this issue be closed now? There is an example for merging PDFs in the docs now.

[bn3t]

Yes thanks a lot.
