My app is running on a Java EE Server, trying to write rendered images to
byte array to put them in XML.
But first I need to render them, and that's not working.
Thanks,

Here is one sample :
http://www.cinemas-utopia.org/admin/grilles/toulouse/2015-06-30.pdf
I tried with 1.8.9 but the render is black and White and text is moved. (I
need the same result pdf = img)

Hi,
is it possible to get a hand on the pdf in question?

Just so you know, flush() or close() are both no-ops on a ByteArrayOutputStream,
so there’s no need to call them. That’s not the cause of your problem, but it seemed
worth mentioning.

Yes, avoid this:
pdfSplitted = new PDDocument();
System.out.println(new String(pdfBytes));
pdfSplitted = PDDocument.load(pdfBytes);
You created an empty document, and then overwrote the variable. And I don't see where you close
pdfSplitted.

Good news today, it's not a thread problem, not a code problem but a file
problem :
While I split my document into 7 parts (one for each day) : Example
<http://www.cinemas-utopia.org/admin/grilles/toulouse/2015-06-30.pdf>
My document is not well saved. (Worked fine on 1.8.9).
Here's my old code that need to be updated :
int splits = 0;
for(PDPage unePage: lesPagesDecoupes){
if(splits >= nbOfCrops){
splits =0;
}
PDRectangle cropBox1 = unePage.getCropBox();
PDRectangle rectangle = new PDRectangle();
float croppingHeight = ((cropBox1.getUpperRightY() -
> (unePage.getMediaBox().getLowerLeftY()))/nbOfCrops);
rectangle.setUpperRightY((float) (cropBox1.getUpperRightY() -
> (croppingHeight * (splits))));
rectangle.setLowerLeftY((float) (cropBox1.getUpperRightY() -
> (croppingHeight*(splits + 1))));
rectangle.setUpperRightX(cropBox1.getUpperRightX());
rectangle.setLowerLeftX(cropBox1.getLowerLeftX());
unePage.setCropBox(rectangle);
unePage.setMediaBox(rectangle);
> pdfSplit.importPage(unePage);
> splits++;
}
pagesSplit.close();
try {
pdf.close();
pdf = pdfSplit;
pdfSplit.close();
} catch (Exception e) {
e.printStackTrace();

The problem is at the end, so, how can I transfer the Splitted PDDoc to the
General PDDoc ?

I will submit you tomorrow the exact pdf file, because i'm splitting it in
7 part. And also tell you if it's a thread problem.
Thanks
The code works fine for me.

If this hint doesn't help, please create a "minimal" servlet project that
can be tested with tomcat and which shows the problem.

The code works fine for me.
However you didn't show how the "pdf" object is closed. Be aware that
PDFBox doesn't support multithreading, i.e. one PDDocument object should
be used only by one thread.
