I have not test more to see if I've made a mistake.

I made a mistake in my example of the
-m option using the '
s' unit (three posts back). I have edited that post and fixed it, but let's say your source file is internally rendered at 700 x 1000 pixels using your specified input dpi value and you want to crop it as above (74p,145p,74p,81p). Then the equivalent 's' values would be 74/700,145/1000,74/700,81/1000, e.g.
-m .106s,.145s,.106s,.081s
The advantage of specifying this way is that the crop margins are independent of the resolution at which the source file is rendered.
