> Hello,
> In the DSS framework, I try to retrieve the original document from a signed PDF. If the document before adding the signature finished with '%%EOF', it doesn't work. Actually, it only works if the document is finished with a EOL character.
> After some investigations, I found this line in the [PDFBox project|https://github.com/apache/pdfbox/blob/2.0.8/pdfbox/src/main/java/org/apache/pdfbox/pdfwriter/COSWriter.java#L1126].
> IMHO, the EOL shouldn't be added after the '%%EOF'. If we refer to the ISO 32000-1:2008 chapter 7.5.5 :
> {panel:title=ISO 32000-1:2008}
> The last line of the file shall contain only the end-of-file marker, %%EOF.
> {panel}
> When I do a saveIncremental, the data to be signed finishes with a EOL character.
> So, I'm not able to retrieve exactly the same binaries. In some cases, it matches otherwise I have a EOL too much.
> Could you have a look ?
> Thanks in advance
