 The current geographic region and mask settings are
 respected when reading the input file.  The presence of a
 mask will, in general, make the resulting fast Fourier
 transform invalid, or at least difficult to interpret.
 
+<h2>EXAMPLE</h2>
+
+North Carolina example:
+
+<div class="code"><pre>
+g.region rast=lsat7_2002_70
+i.fft input_image=lsat7_2002_70 real=lsat7_2002_70.real imaginary=lsat7_2002_70.imag
+
+# set region to resulting FFT output map (due to new FFT coordinate space):
+g.region rast=lsat7_2002_70.real -p
+d.mon x0
+d.rast lsat7_2002_70.real
