Quick answer:
I looked at the page content stream using the PDFBox Debugger and
appendRectangle isn't triggering because there isn't a rectangle in the page
content stream. What is rendered is made up from a move and lines. I also had
to handle this in my project. One way would be to Override other methods so
that you catch a moveTo, lineTo, closePath strokeAndFill etc and store the
points, to see when closePath is called if they form a rectangle.
If I have time, I am about to go on a business trip, I will see if I can cut
down my code to illustrate this.

Seems like I cant use the appendRectangle method. It does not trigger.

Betreff: Re: Finding a Box containing text
Hello Lukas,
This mailing list doesn't accept attachments; you probably want to use a
hosting site instead.
I am currently working on a project that needs to identify text on a page
within a rectangle.
This may or may not be appropriate but to do this I Overrride
"PDFGraphicsStreamEngine"; Which has a method appendRectangle, if your PDF
creation application is well behaved you can just use that. That said in the
real world a rectangle can be made up of lines and moves, so you may have a bit
more work to do. If you have the coordinates of the start of the string, then
you could enumerate the rectangles to see if the point was in a rectangle. Or
you could use do things slightly in reverse and use the bounds of the rectangle
and use the TextStripperByArea to get the text in the rectangle and identify if
the string is what you are looking for.
Unfortunately I can't share my project code but if you can find somewhere to
host the PDF, I will see if I can use it as a test for my code and if that is
successful provide something by way of a slimmed down example.

I am trying to find (x,y,widht,height) of a box containing a text within an PDF
document. Locating the text by inheriting the TextPosition was pretty
straightforward, but I had to realize that I don’t know PDF Operators well
enough to locate the box.
Can somebody please have a look at the PDF I attached and tell me which „q“ –
„Q“ block represents my „FIND ME“ Box. Can I subclass PDFRenderer to get the
Box position?
Regards,
Lukas
