PDF page rotation

[Mohith Manoj <mohith manoj skanray com>]

Hi,
I have an application that needs to generate landscape style A4 reports. 
I have derived the Gtk::PrintOperation class to suite my needs and it 
works well. The reports generated are in landscape form itself when the 
printer is a physical printer or a PDF printer.

However when I export the job to a PDF file using 
Gtk::PRINT_OPERATION_ACTION_EXPORT,  the PDF file generated is always 
portrait. Though all the contents are intact, the pages are rotated 
90degree counter clockwise. I tried toggling with the page and print 
settings by settings wider page size without any luck.

Is there any separate method to follow while exporting to PDF so that I 
can set the rotation property in the PDF file? Or is there something 
extra I need to do while setting print settings or page settings?
