Don't forget the PNG command also takes a "ray" argument:

 png fileName, height=X, width=Y, ray=1, dpi=300

PyMOL will resample in that case.  You always get a ray traced file
from that command.

If you do:
  ray 300, 300
  png fileName.ong, height=1000, width=1000

You get a 1000,1000 non-ray traced image.
