Michael Kuß edited comment on PDFBOX-1618 at 6/3/13 9:21 AM: ------------------------------------------------------------- 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 "...-3.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. (seen as -Teil4.pdf) was (Author: michael.kuss): I analysed a little bit more on this.
