Andreas Lehmkühler commented on PDFBOX-5462:


The behaviour changed in 3.x. 2.x implements different strategies to cache 
things which makes the code complicated, hard to maintain and sort of 
nontransparent. Consequently some of the internal caching (scratch files aren't 
used for reading anymore) was removed so that the user has to care about it.

if you are dealing with streams you might want to spool them to a file first 
especially if the corresponding pdf is a bigger one. 2.x does the same under 
the hood but 3.x no more. 

I'm going to add some more details about that change to the 3.x migration guide

[~lehmi]  I understand you, but I can't: in the real application I have a PDF 
streamed over the net! And, as I said, it used to work with 2.x series 
libraries, why it shouldn't work now ?

The language settings shouldn't have any impact. I'm using different JDKs and 
I've used 1.8.0_202 in this case, but I guess that shouldn't have any impact 
too.

W.r.t. the 4K pages file. I won't test that. It is an 1.2GB file. If you are 
still using an InputStream the first thing PDFBox does is copy that file into 
memory which allocates 1.2GB of it. *+Pass the file to loadPDF instead of 
creating an InputStream first+*

Andreas Lehmkühler commented on PDFBOX-5462:


The language settings should have any impact. I'm using different JDKs, I've 
used 1.8.0_202 in this case, but I guess that shouldn't have any impact too.

W.r.t. the 4K pages file. I won't test that. It is an 1.2GB file. If you are 
still using an InputStream the first thing PDFBox does is to copy that file 
into memory allocation 1.2GB of it. Pass the file to loadPDF instead of 
creating an InputStream first

[~lehmi]  the code I use is the same as yours from 
https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/util/AddWatermarkText.java?view=markup
 the only difference is that you instantiate the font for every page while I do 
it once, would that be the cause? I shall give it a try tomorrow...

[~lehmi] my environment is Ubuntu (now {*}22.04{*}) with java {*}build 
17.0.3+7-Ubuntu-0ubuntu0.22.04.1{*}. I've tested the program on 2 i7 computers, 
a Dell laptop and an Intel {*}NUC8i7BEH{*}, both exhibit the same malfunction.

I attached the jar I use to this issue, try with it please ; try also to create 
a 4 k pages sample and use it on it, or download 
[https://server.famion.eu/4k_pages.pdf]

What is the status of this ticket? I guess PDFBOX-5286 solves the performance 
issues. Is there anything else to be done? Do we have to do that in 3.0.0 or 
can it be done later?

> *TL;DR:*
> Currently it is rather tedious to create incremental changes in between 
> signatures via PDFBox. I attempted to simplify that and wrote a patch.
> This is rather a POC, than an actual suggestion for direct inclusion. (For 
> reasons explained later.)
> *Signatures and incremental PDF documents:*
> A typical reason for wanting to sign a document multiple times (creating an 
> incremental PDF) is , that in between signatures the document changed and the 
> additional signature shall sign the new state of the document.
> If one wanted to implement such incremental changes using PDFBox, he would 
> find, that most of the time made changes are completly ignored, when calling 
> "saveIncremental".
> As documented for the "saveIncremental" methods and especially the matching 
> constructors in "COSWriter", this would require, to identify the "path" of 
> all made changes and one would need to set the "needToBeUpdated" flag of all 
> elements of that path.
> *But:*
> As documented one would have to have exact understanding of what he did and 
> how the PDF standard does implement this, he would have to identify said 
> structures and the more complex the changes were, the more tedious this would 
> become.
> *Also:*
> Because of the implementation of incremental saving in COSWriter, the whole 
> path must be informed that it required an update.
> Resulting in unnecessary large increments, as not all ancestors might 
> actually have changed.
> e.g. If one added an image to a preexisting page of the document - the 
> contentstream, the resources of the page and the page dictionary would have 
> changed. But the "pages" array and all it's ancestors would not have changed 
> a bit, but still would have to be informed and included.
> *Assumptions that lead to this patch:*
> - COSWriter should not stop iterating a COSTree

Andreas Lehmkühler commented on PDFBOX-5462:


[~john75] Thanks for the sample code and file

I'm afraid everything works fine for me, no exception. I've tried the following:

* I've created a sample file with 512 pages using the provide script. BTW, the 
provided pdf sample1.pdf is quite inefficient. 3 of the 4 pages contain one 
image, but all pages are referencing all images within their resources.
* using {{org.apache.pdfbox.examples.util.AddWatermarkText}} took 2 seconds to 
watermark the pdf
* using your code took 12 seconds to watermark the pdf

I've optimized some of your code:
* use a File instead of an InputStream as input. The parser needs random access 
to the pdf so that the data from the input stream has to be copied somewhere 
temporarily. The changes in 3.0.0 made it more efficient to use a file as input
* wrap the OutputStream into an BufferedStream or simply use a File as output 
and PDFBox will do that for you

In the end your code is as fast as the example. It takes 1,5 seconds to 
watermark the file.

I didn't use any additional JVM settings such as -Xmx and even the memory 
settings for the loadPDF-method aren't needed at all. I've run all test within 
my eclipse environment on an elderly pc (i7-3770, 16GB) using linux.

The question is, what is different in your environment? What hardware are you 
using?

I forgot about this one but I think all is done here. We can't handle tiled /
