This is not supported by POV-Ray; you will have to calculate the proper
resolution (e.g. 5.43*300 = 1629 by 3.24*300 = 972 pixels), and then run the
image through an image-processing software such as Gimp, Photoshop or
what-have-you.

See section "3.1.2.4.1  Output File Type" in the POV-Ray 3.6 documentation. You
can enter the appropriate options (e.g. "+FT" for TGA) in the field to the
right of the resolution dropdown box.

That's also the box to use for ad-hoc custom resolutions. See section "3.1.2.2.1
 Height and Width of Output" for how to specify the resolution.

For instance, for a 5.43 x 3.24 inch image at 300 DPI in TGA format, you'd
specify "+FT +W1629 +H972". (But, as already said, you'd have to fix the DPIs
using an image processing tool.)
