[poppler] Annotation support

[Tim Hoffmann]

Hi,

I'm trying to get the coordinates of annotations in a pdf file using  
the qt-interface. However with most annotation types the boundary rect  
has x and y but no width nor height.

I'm especially interested in highlight annotations. But here again the  
annotation has a position, but no width and height. Also the  
highlightQuads() constist of four points which are identical to the  
the position. I would have expected an area spanned by four points.

The annotations were generated from LaTeX via pdfcomment and display  
is correct in Adobe Acrobat. I'm using poppler v0.16.7 (Ubuntu). Are  
these annotations not yet completely implemented or do I misunderstand  
how these values are to be interpreted? If the second is the case,  
could you hint me at some information on position and dimension of  
annotations? Thanks!

Regards,
Tim
