CombinePDF#pages - individual page sizes same as entire original file

[leviwilson]

We've been using CombinePDF to "split" pages (for some post-processing) like so:

CombinePDF.load(file, allow_optional_content: true).pages.each_with_index do |page, page_number|
  path = "page_#{page_number.to_s.rjust(4, 0')}.pdf"
  (CombinePDF.new << page).save(path)
  Page.create file: File.open(path)
end

For some documents we've had, their file size might be 32MB though when we split with #pages, each individual page ends up being the same size as the original document. This wouldn't be that big of a deal, though this example has 865 pages (so 865 ✖️ 32MB is a lot).

If I had a non-PII example to add to this issue I would, but unfortunately I don't at this time.

This is more of a question than an issue (I think) but thought I'd ask to see what about this document is special to where this happens.

Closing this issue. It appears to be the same result using poppler utils as well; I'm guessing each page references elements in the document and continues to re-use them per page.

Isn't an issue with combine_pdf so closing this.
