Thanks ;)

[gastendonk]

I suggest to try this option:

    SimpleEnvironment env = new SimpleEnvironment();
    env.setAddEqualPagesToResult(false);

And why do you verify Excel files using PDF? You can compare Excel files using Apache POI.

[finsterwalder]

Comparing Excel files as a PDF does sound strange...

But back to the problem: You are simply running out of memory. PdfCompare needs quite a lot of memory per page compared.You can reduce the amount of memory used by not storing equal pages, as @gastendonk suggested. But to completely solves this problem, look at the compare results with overflow: https://github.com/red6/pdfcompare#different-compareresult-implementations

[steevi2307]

Hi,

I'm running 16go of RAM and during comparison, the memory goes up to 10go (java process goes up to 4go) But it's seems to work in this case with the setAddEqualPagesToResult(false)

So it's ok for me :)

Thanks !

[finsterwalder]

Your JVM definitely runs out of memory. That what it tells you here:

Caused by: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space

[steevi2307]

Hi,

And do you know we can bypass this ? Because we have two other files to compare (8mo pdf - 670 pages) and the I have now the same problem ...

Memory usage : 57% (java +/- 4.5Go)

https://drive.google.com/file/d/10kM0w7bOLd5juEJOFZU8xhFPi50jrbRj/view?usp=sharing https://drive.google.com/file/d/1ytTnUDDSIsg3vSeTe7pe4hGXYbhzD6PV/view?usp=sharing

Thanks ;)

[finsterwalder]

Like I said above:

But to completely solves this problem, look at the compare results with overflow: https://github.com/red6/pdfcompare#different-compareresult-implementations

[steevi2307]

Hi, Do you have a sample to simply to limit the memory in our case :

final CompareResult result = new PdfComparator(x, y).withEnvironment(new SimpleEnvironment().setAddEqualPagesToResult(false)).compare();

And if possible without an application.conf file

I don't have to use CompareResult anymore if I understand ?

Thanks

[finsterwalder]

Just use new PdfComparator(x, y, new CompareResultWithPageOverflow()) or new PdfComparator(x, y, new CompareResultWithPageOverflow(<maxNrOfPages>))

[steevi2307]

And it's possible in this way to have a "diff" file showing differences as previous call ?

[finsterwalder]

The result is the same. The only difference is, that compared pages are swapped to disk and merged at the end.

[steevi2307]

It seems to work ; thanks ! :)

[steevi2307]

Hi,

Another question : everything works fine but the comparison is a little bit long for large pdf files (50 minutes for 1500 pages) Is there a way to optimise this ?

Thanks

[finsterwalder]

General note: Please don't reopen tickets to discuss a completely different subject. Open a new issue instead.

Unfortunately there is nothing easy you can do to improve performance. I've been playing around with more parallel threads, but the underlying PdfBox library I use is not easily thread safe when rendering pages. Rendering pages and comparing them is already running in parallel.
