For a figure that does not need the aspect ratio preserved,
and needs to fill a 1280x1024 projector display:
<pre>
sfprep4plot inp=file1.rsf out=file2.rsf w=1280 h=1024 prar=n
</pre>
For a print figure that has to fit in a 6x8in box
at a resolution of 250 dpi, preserving the aspect ratio:
<pre>
sfprep4plot inp=file1.rsf out=file2.rsf w=6 h=8 unit=in ppi=250
</pre>
