---------------------------------------------------------------
Are images re-encoded? I'm playing around with itext rups to inspect the
content of the pages. I'm comparing a result from the first page compared a
smaller file produced by ghostscript and I noticed that the length of the image
stream is very long:
pdfbox:
{code}
<<
/BitsPerComponent 8
/ColorSpace /DeviceGray
/Filter /DCTDecode
/Height 1803
/Length 261723
/Subtype /Image
/Type /XObject
/Width 1100
>>
stream
{code}
gs:
{code}
<</Subtype/Image
/ColorSpace/DeviceGray
/Width 1100
/Height 1803
/BitsPerComponent 8
/Filter/DCTDecode/Length 168521>>

> Key: PDFBOX-3816
> URL: https://issues.apache.org/jira/browse/PDFBOX-3816
> Project: PDFBox
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 2.0.6
> Reporter: Mike Cantrell
> Priority: Minor
>
> It seems that there are still issues surrounding inflated PDF page sizes when
> performing split operations. See PDFBOX-1618 for background.
> My test PDF is 97MB and the resulting pages are 851MB. The following
> demonstrates the issue with the command line tool:
> {code}
> curl https://storage.googleapis.com/pids-share/high-rez-color.pdf -o test.pdf
> java -jar $PDFBOXTOOLS/pdfbox-app-2.0.6.jar PDFSplit test.pdf
> {code}
