flattening
Hallo.
It is clear, that flattening does have a bug. Compare flattening of
PDFBox with IText and you realize, that PDFBox destroys all fields, once
I call
acroform.flatten(fields, true) or acroform.flatten(fields, false)
.
How can I request someone to fix flattening and make it work like in
IText. That is that the right fields are flattened while all the other
fields remain untouched!

I've created a small test which is running fine:
PDDocument document = Loader.loadPDF(new File(IN_DIR, NAME_OF_PDF));
PDAcroForm acroForm = document.getDocumentCatalog().getAcroForm();
int numFieldsBefore = acroForm.getFields().size();
List<PDField> toBeFlattened = new ArrayList<>();
PDTextField field = (PDTextField) acroForm.getField("AlignLeft-
Filled");
toBeFlattened.add(field);
acroForm.flatten(toBeFlattened,false);
assertEquals(numFieldsBefore, acroForm.getFields().size() + 1, "The
number of form fields shall be reduced by one");
A manual inspection of the result shows that all fields but one are
still accessible.
The file being used was
src/test/resources/org/apache/pdfbox/pdmodel/interactive/form/Multiline
Fields.pdf
Version used was the current trunk.
So please do a similar test with your files. I'm not saying there is no
bug but we have to be able to reproduce it to be able to solve it. With
the files I've tested with the result is fine.

Hello,
Please tell what PDFBox version you're using and create a MINIMAL
reproducer. Your current code does not flatten at all (because flatten
is commented out), and uses an external class do do something that isn't
related to flattening. Your reproducer should just load the file, select
some fields, and flatten and produce the problem.

I know how Itext works and PDFBox does not work the same. In Itext the
result is that only the right fields are flattened. It seems there is a bug.
In PdfBox every field is flattened, even though I delivered a list of
fields, that were meant to be flattened.
It seems the PDF is destroyed by flattening.
I have attached the code.

Here's a PDF flattened by itext
https://github.com/itext/i7js-examples/blob/develop/cmpfiles/sandbox/acroforms/cmp_checkbox_flatten.pdf
and they do something similar to what we do, i.e. remove the fields and
converting it to form XObjects.

the purpose of flatten is that the flattened fields are removed and
become part of the regular page content.
If you'd like to keep the field but would like it to be protected you
have to set the field to read only. Keep in mind that one could use a
lib and remove the flag and change the content afterwards.
Now, if there is really a bug I need to have a clear description how to
reproduce it together with sample content. If you're able to provide
that I'm happy to take a look.

Hi,
Please read and follow these instructions:
https://pdfbox.apache.org/support.html
Make sure you're using the latest version, and it it happens, please
open a ticket and attach your file and the flattened file and the itext
flattened file.
