PDFBOX-3164: make method called in constructor final
> XFDF partially incorrectly rendered or exceptions when parsing
> --------------------------------------------------------------
>
> Key: PDFBOX-3164
> URL: https://issues.apache.org/jira/browse/PDFBOX-3164
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.8.10, 2.0.0
> Environment: Windows 7 SP1 Enterprise, 64 Bit, Java 8u66 64 Bit
> Reporter: Matthias Stoll
> Attachments: XFDFStamper.java, samples.zip
>
>
> I am currently investigating in using PDFBox (my tests used PFDBox 2.0RC2)
> for a small use case „stamping“ annotations from a given XFDF format (created
> by Qoppa’s jPDFEditor/jPDFNotes, www.qoppa.com) into a given PDF/A-1b file.
> This works with a surprisingly minimal set of Java code line But: obviously
> not all XFDF elements are supported and/or there are bugs in reading XFDF up
> to now.
> I just wanted to let you know about my experiences.
> a) Drawing lines painted by a pencil (element: “<gesture>”) do not show up
> at all after stamping them. Why?
> Sample data to test with:
> <ink name="C2B070EBB736993EA25F4545350AD2C3" style="solid" width="4.0"
> flags="print" date="D:20151207122033+01'00'" color="#00ff00"
> opacity="1.0" page="0" subject="Bleistift"
> rect="62.4562,1378.1637,167.5599,1402.8388"

> b) Polygons (at least when created with jPDFNotes) throw an exception when
> reading:
> Exception in thread "main" java.lang.NumberFormatException: For input string:

> d) A freetext (“<freetext>”) element will not show up correctly:
> b1) Though “width=0.0” for the box, it PDFBox will render a box around the
> text
> b2) Though font is set to “font: Courier 12pt; color:#000000” a wrong font
> will be rendered
> b3) The color setting will be ignored: my tests setting a color of font and
> border to red showed up a textbox with black border and black text.
> e) A freetext element with legend options does not show up correctly:
> e1) Colors are wrong/ignored
> e2) Font size not correct
> e3) Legend arrow not drawn
> Sample data to test with:
> <freetext name="95DB90502D987FDE0DD5446ED48C098A" style="solid" width="3.0"
> justification="left" flags="print" date="D:20151207122813+01'00'"

> There might be more of such issues – but I think this should be sufficient
> info for now to check how to proceed.
> Adobe Acrobat renders all these test cases correctly by the way, so I assume
> the XFDF elements are all correct.
> I can provide the sample code if needed – where shall I upload it – if needed?
> As I do not find that much info about the support of XFDF in various PDF
> libraries – what about the official support in PDFBox? Should all of the
> samples work? What are the plans to do so?
> Thanks a lot in advance.
