Dear all,

I implemented PDF rendering in Qt application.
My opinion is that Poppler is not the best piece of open source code, 
look the code in comparison to MuPDF, it is C but clean C and run on 
embedded devices.
Rather Poppler is more like a pile-up of crappy codes.  Some years ago, 
somebody complained that Poppler doesn't use the same rendering engine 
on Gnome and KDE ...
And Okular is nearly unable to print a document, try to print a 10 cm 
square on a printer or to do complex printing, personally I would prefer 
to boot Windows and use Acroread instead.
However I don't have experience with PDFium.
