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