Subject Re: Can PDFBox extract text from PDF Documents that have "text boxes" ?
Date Fri, 14 Jan 2011 17:43:47 GMT
I'm not very familiar with these text boxes nor text extraction, but it 
sounds like that might be a newer feature of the PDF specifications which 
simple has not been implemented yet.  But that's just a guess.  If you can 
find out what software created those PDF files, it might help give us some 
more information.  In Adobe acrobat: File -> Properties; check the "PDF 
Producer" and "PDF Version".  If you can get the software which was used 
and create a test PDF which fails to extract text, we could look over the 
technical data and better help you figure out what's going on.

Can PDFBox extract text from PDF Documents that have "text boxes" ?

I have PDF Documents that have apparently been edited by some kind of PDF 
Writing Application.
When edits are made... people are adding "Text Boxes" to the Documents 
instead of just removing/editing the existing Text.
Each of the Edits have a colored boundary around them.
These 'Text Boxes' are always placed inbetween original lines of Text.

If the Document were not locked.. I could click and drag the boxes of Text 
around on the Screen.
When I mouse-over them and right-click and select Properties...
The window displayed is titled  "Text Box Properties."

When I attempt to extract text from the PDF Document...
I either get runtime exceptions from within PDFBox's API
Or.. I get Text back.. but NONE of the text from these "Text Boxes" is 

Does anyone have working sample of code that can successfully retrieve 
Text from something like this ?

I would love to provide an example, unfortunately the PDFs contain 
proprietary information so I am not allowed to do that.
