Links are lost

[pedroresende]

I'm attempting to merge two PDF files, however, when doing so, it strips the links out. The code

const appendPdf = (inputPdfPathArray, outputPath) => {
    const pdfWriter = muhammara.createWriter(outputPath)

    for (const filePath of inputPdfPathArray) {
      pdfWriter.appendPDFPagesFromPDF(filePath)
    }

    pdfWriter.end()
}

@mhassan1 Thanks for the suggestion, I've attempted to use it, however, the result is the same. I've attempted to debug a bit and apparently the params content is the following

params {
  page: PDFPage {
    rotate: 0,
    artBox: undefined,
    trimBox: undefined,
    bleedBox: undefined,
    cropBox: undefined,
    mediaBox: [ 0, 0, 594.95996, 841.91998 ]
  },
  pageDictionaryContext: DictionaryContext {},
  writer: PDFWriter {
    events: EventEmitter {
      _events: [Object: null prototype] {},
      _eventsCount: 0,
      _maxListeners: undefined,
      [Symbol(kCapture)]: false
    }
  }
}

It looks like PDF Writer does not support that so far. The appendPDF or mergePages etc function do not allow to set const ObjectIDTypeList& inCopyAdditionalObjects maybe something is possible with CreateFormXObjectsFromPDF which allows setting the objectIds to be copied.
