[PDFBOX-2.0] PDF Size after Signature
Hi all,
I'm using PDFBOX 2.0 to sign some documents and I found that the size of
signed file is too big if compared with 1.8 version, sometimes those files
get their sizes increased in 100% or more. When the same file is signed
using 1.8 the file is increased in a expected way.
Original File: https://www.dropbox.com/s/s8p40ukorhchtcu/sign_me.pdf?dl=0
Signed With 1.8:
https://www.dropbox.com/s/ty8axylq8ol6204/sign_me_signed_1.8.pdf?dl=0
Signed With 2.0:
https://www.dropbox.com/s/ge1x3mdpqlalnvq/sign_me_signed_2.0.pdf?dl=0
There is some option to reduce the signed file size on 2.0?
Best regards

My changes (PDFBOX-1822, PDFBOX-2515) where made prior to PDFBOX-2685. Saying
that, r1659998 could introduce a regression. I had a quick look and maybe the
changes made to COSWriter are the root cause. But we have to debug that first to
be sure.

Hi Andreas,
the changes you made were these before or after the ones I did to COSBase wrt to immutable objects (PDFBOX-2685)?

Correct, something went wrong when appending the changed objects only. It work
for
me when I fixed the encryption stuff. I seems as if some recent change
introduced
this regression.
@Isaias
Which exact version/revision of the trunk are you using?

Hi Andreas,
I've tested it now. The problem was fixed. Follow evidence to the same file
used on initial tests.

I've fixed the regression. The recent trunk works as expected and no longer blow
up the size of a signed pdf.

Hi Tilman,
I've started testing the signing feature with 2.0 before migrate from 1.8
to 2.0, so my focus was to get the document signed, Andreas has solved some
problems and I started to use, just now that I migrated the real code I've
noticed the size increase, in this way I can't say if it is recent or not.
Thank you

Did you just start with signing or is this a recent phenomenon, i.e.
didn't happen a month ago?
I looked at both files - in the 1.8 one, only the changed objects appear
after EOF. In the 2.0 one, all objects are there ?!
