If you want to render a 10x8 inch image at 300 dpi/ppi just multiply
the width and height of the final dimension by the required resolution.
Thus:
10 inches x 300 dpi = 3000 pixels wide
8 inches x 300 dpi = 2400 pixels wide
Now render your image setting W to 3000 and H to 2400 in your ini
file (see the POV documentation on how to do this). In your image
processing program, just scale the image to the required dimension in
inches with the resolution set to 300 ppi.
Perhaps the (edited) ini file below will be of use; I use it for most of my
work.
Best wishes,
Nicholas
