Detailed Description

Color spectrums show colors corresponding to values between zero and one. The ColorScale class adds the ability to use different minimum and maximum values for the spectrum (ie it essentially just scales and translates the spectrum). A spectrum also has a vertical or horizontal orientation, with horizontal being the default.

Constructor & Destructor Documentation

ColorSpectrumWidget()

ColorSpectrumWidget

(

QWidget *

parent = nullptr

)

Constructs a widget with a default orientation of Qt::Horizontal and no points in the spectrum. Clients would normally need to set the spectrum after construction, since an empty spectrum serves no useful purpose for this widget (ie it will simply show solid black).
