Well if I reproduce the math involved I get that the PNG should
contain:
11811 pixels/meter which converts to 299.9994 pixels/inch. If your
software reports
that as 299 then that software is (IMHO) broken. That said you can always
lie on
the input side so to get 11812 pixels/meter (i.e. 300.025 dpi) in the PNG
file , to do that
you should claim that your PIXEL_UNIT_TO_MILLIMETER is 1000/11812 or
'0.08466'.
