<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 "1" is the same thing as
|
|
|
37 |
disabling super-sampling. This will generate a fast image but a LED
|
|
|
38 |
appearance that looks quite "rugged".</P>
|
|
|
39 |
<P> Increasing the level of oversampling above "4" 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>
