[jira] [Commented] (PDFBOX-5317) Splitter: Problematic /Info causes big files

    [ https://issues.apache.org/jira/browse/PDFBOX-5317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17464609#comment-17464609 ] 

Mario Jerome Kofler commented on PDFBOX-5317:
---------------------------------------------

Unfortunately, there are still PDFs for which the Splitter does not work correctly,  i.e. the splitted documents have the same (full) size as the original document. I identified two cases:
 * PDFs created via the online PDF converter [https://online2pdf.com/]
 * PDFs created using the PHP library fpdf [http://www.fpdf.org/]

In these two cases (and possibly even more  PDF converter) the split pages still have the full size of the original document. Attached you find the original attachment for this report converted to PDF again using the [https://online2pdf.com/] tool for testing.

> The attached pdf uses the same object for /Root and /Info, so /Info also contains the /Pages reference.
> When splitting this document, /Info gets a copy of the original object, which still contains all pages.
> I would propose to create a new /Info entry instead of just copying the old one.
