Text Bounding Boxes and Reflowing
Hi -
My ultimate goal is to be able to properly replace text and 'reflow' it - I
know this isn't handled out of the box, but there are a few subproblems I
am trying to first solve that would help me towards this goal. Also, my
text reflowing does not need to be perfect! Just 'kind of work. I am doing
my best to replicate what Acrobat does when you click 'Edit' text as my
attempt, specifically:
A. Like in acrobat when a user clicks 'edit' pdf, it seems that contiguous
areas of text are put together into a single editable textbox, and text
reflows within this text box. Does PDFBOX (or other suggested libraries)
have heuristics or other ideas on how to create these 'paragraph' like
bounding boxes?
B. Acrobat, for instance, will reflow and refit text naturally put inside
of a Form Text Field. Does PDFBOX support form text fields (that presumably
would fit/reflow the text inside of them?) and be able to 'flatten' it?
Anyway - any suggestions are welcome - thanks a lot!
Nick

No recommandation... a google search finds this:
https://hardmockcafe.blogspot.com/2016/04/pdf-text-layout-made-easy-with-pdfbox_17.html
But as I said, somewhere in AppearanceGeneratorHelper.java there is code
to format text, see the call to PlainTextFormatter.
Re: "using a form field" - no, that makes no sense, unless it is a form
field.

Okay great - with regard to adding text, would you recommend any libraries,
i.e. that have helpful methods 'autofit to size' at all, or reflowing
within them? For instance, using a form field to do this?
Thanks.

PDFTextStripper has heuristics for paragraphs. This issue
https://issues.apache.org/jira/browse/PDFBOX-3804
has test files and a parameter to change.
Yes it does support form fields and flattening. But that is something
different than the first problem. Start with
AppearanceGeneratorHelper.java and search from there...
