I should mention that I am trying to do this:

$ qgis --project Natural_Earth_Shriramana.qgs --snapshot world.png
--width 21600 --height 10800

but somehow it is placing the map in a small size on a very big white
background. Adding --extent -180,-90,180,90 doesn't help either. Or am
I doing something wrong?
