Tilman Hausherr commented on PDFBOX-4597:
-----------------------------------------

Yes... I wrote "undefined" as in "I'm not sure what it does for these, so lets 
not pretend anything" because I'm not sure if one of the other angles would 
possibly return 90/180/270. I had the same thought of calculating the angle 
like I do for the "rotation magic" in ExtractText, where all angles are 
supported but also feared problems with existing code.

> Please explain the difference between "page rotation adjusted coordinates" 
> and "text direction adjusted coordinates" as referenced by the TextPosition 
> class. You can add an explanation (ideally a visual one) to the class or 
> method Javadoc.
