[jira] [Resolved] (PDFBOX-785) Spliting a PDF creates unnecessarily large files

["Andreas Lehmkühler (JIRA)" <ji...@apache.org>]

Andreas Lehmkühler resolved PDFBOX-785.
---------------------------------------
    Resolution: Fixed

I've followed 2 of the obvious proposals:
- add compression to the stream of the imported pages
- remove all pages from annotation links to avoid copying of unneeded resources

Thanks to all for their input/help/contribution

>    Affects Versions: 1.8.8, 2.0.0
>         Environment: Windows XP, openOffice3.0.0, pdfsam

> Using PDFBox 0.8.0 (also tried on 1.1.0 and 1.2.1) to split files result in bigger parts than the original.
> Concerned files were made from openOffice .odt documents in version 3.0.0 using openOffice pdf Export and then merging several copies with pdfsam (http://www.pdfsam.org/)
> In joined eclipse project the test file size is 10 712 749  bytes for 2812 pages and the result file sizes after splitting in two at page 2300 are : 8 812 515  bytes and 10 701 142 bytes.
> Using pdfSplit in command line as result we have all single result files bigger than the original. An example is also attached. An error tells the original file is corrupted, but we tried it on a file (using pdfsam and without using it) with no error and with similar result, so I think it's not related. 
> This issue seems similar to PDFBOX-28.
