Thomas Chojecki commented on PDFBOX-3169:
-----------------------------------------
Yes. This will not solve the main need for easy incremental update of pdfs, but
make it possible to do some minor incremental updates like augmenting
signatures or something else that isn't complicated.
After applying this patch at home, the saveIncremental method should work as it
does in the 1.8 branch.

> Key: PDFBOX-3169
> URL: https://issues.apache.org/jira/browse/PDFBOX-3169
> Project: PDFBox
> Issue Type: Bug
> Components: Writing
> Affects Versions: 2.0.0
> Reporter: Thomas Chojecki
> Assignee: Thomas Chojecki
> Attachments: saveIncremental.patch
>
>
> I know this feature is ongoing, but with the 2.0.0-RC builds the
> saveIncremental (without signature) stop working at all. A
> ByteArrayOutputStream is used in the COSWriter for output. This OutputStream
> will only be handled in the case, when we write a signature. Otherwise the
> whole content will be discarded.
> As I wrote some time ago on the mailinglist, incremental update work in a
> limited way. At the moment we use it for augmenting signatures and this works
> with the old 1.8.x but not with trunk after the patch PDFBOX-1847 was applied.
