Interface PdfDestById

Destination that follows a logical page when the page arrangement changes.

The pageId is the opaque identity of a PdfPage placement, not a PDF object number or page index. Normally, do not construct this object or handle the ID directly; use PdfPage.dest on the target page:

const dest = document.pages[4]!.dest({
  by: 'id',
  command: 'fit',
  params: [],
});
Copy

The resulting destination follows that logical page through reordering. When the same identity appears more than once, one matching placement is selected; use PdfPage.duplicate when placements need distinct identities.
