[jira] [Commented] (PDFBOX-1618) Split PDF file to single page files, some files are inflated in size

    [ https://issues.apache.org/jira/browse/PDFBOX-1618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13672943#comment-13672943 ] 

Michael Kuß commented on PDFBOX-1618:
-------------------------------------

I analysed a little bit more on this. There some differences between splitting documents with pdfbox and Adobe.
- one is the missing compression, that is lost during importPage in the PDDocument.
- another thing is, that links (annots) on a splitted page to another page (not in the part) will result in a completetly copied dependency tree. So the linked page will also be included. Adobe will leave the references as is with the linked pages missing. 
  I don't think this is actually a bug, but it would be nice to have a similar functionality as in Adobe. Also IMHO the complete page referenced in a internal pdf hyperlink should not be repeated.

e.g. if I take "...Teil3.pdf" from my attached zip you can see in that the Annots do have the complete page included. I will attach a screenshot from the internal structure seen from adobe.

> A PDF file is split into single pages for inclusion within another document (pdfbox.utils.Splitter within our code but same phenomenon observed when splitting using command line PDFSplit tool). Som of the pages are almost as large as the original file which causes performance problems for our customers.
> Again, I have a sample pdf to attach.
