Class Methods

 

DigitalLED74 ::
SetSupersampling($aSuperSampling)
Set level of supersampling used in the creation led digits

ArgumentDefaultDescription
$aSuperSampling 2 Level of supersampling

Description:
Specifies the amount of oversampling that sould be used to create a smoother looking image. A higher value will generate a smoother image. The value used for supersampling should be an integer in the range 2-4. A higher value could be used but the increase in CPU time will not generate any perceivable improvements in image quality. For each integer step increased supersampling the processor time needed is multipled by 2 

Example:

$led = new DigitalLED74(5);
$led->SetSupersampling(4);
$led->StrokeNumber('ABC123.',LEDC_RED);
