<H2><A NAME="13_2">13.2 Improving the LEDs with supersampling</A></H2>
 In order to improve the visual appearance the library uses
 super-sampling in order to create an anti-aliased image of the LED
 digits. The default level of super-sampling is 3 times (oversampling).
 In order reduce the CPU load the amount of oversampling can be lowered.
 The level of super-sampling is controlled via the method <TT>
DigitalLed74::SetSupersampling::($aSuperSampling=3)</TT>
<P> For example setting the oversampling to &quot;1&quot; is the same thing as
 disabling super-sampling. This will generate a fast image but a LED
 appearance that looks quite &quot;rugged&quot;.</P>
<P> Increasing the level of oversampling above &quot;4&quot; gives almost no
 visual improvement to the resulting image, it will only increase the
 CPU time needed to create the final image. Hence it is recommended that
 the super-sampling is only specified as an integer in the range one to
 four.</P>
