----------------------------------------------------------------
Thanks for pointing that out [~tboehme].
Unfortunately, I got no files that show some of the charactersitic we discuss.
I created some drop cap pdf-files which may be used for further Investigation
on that case, but at the moment I see no way to handle any of these problems.
Even with additional programs doing a segmentation like the one in the jpeg I
posted this would not be an easy Task.

> PDFBox will need some -document layout analysis tools- enhancement to the
> current text extraction to extract text correctly.
> At the Moment the text of a document is extracted using the position of
> single characters.
> This may lead to wrong results, due to the format of the file.
> There are good tools such as https://code.google.com/p/lapdftext which we
> could use to compare our current output.
> Possible enhancements are
> - enhance matching of text to a certain line i.e. don't mix up text from
> different lines
> - better handling of rotated text
> - handling of vertical text
> - ability to get additional text properties such as font, font size ...
> Some of these are already logged as individual tickets
