ColourSpace class sealed

The sealed base class for all colour space representations in Collect.

Every colour space (Colour, HSVColour, HSLColour) extends ColourSpace and implements the three conversion methods, so you can freely convert between any pair of colour spaces.

ColourSpace anyColour = someHSVColour;
final rgb = anyColour.toColour();
final hsl = anyColour.toHSL();

Implementers

• Colour
• HSLColour
• HSVColour

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toColour() → Colour

Converts this colour to its Colour (ARGB) representation.

toHSL() → HSLColour

Converts this colour to its HSLColour representation.

toHSV() → HSVColour

Converts this colour to its HSVColour representation.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

colorFromHue(double alpha, double hue, double chroma, double secondary, double match) → Color

Same as colourFromHue but returns a Flutter Color instead of a Colour. Used internally where the Flutter type is needed directly.

colourFromHue(double alpha, double hue, double chroma, double secondary, double match) → Colour

Constructs a Colour from hue, chroma, secondary component, and match offset values. This is the core algorithm that maps HSL/HSV parameters back to RGB.

getHue(double red, double green, double blue, double max, double delta) → double

Calculates the hue (0-360 degrees) from normalised RGB components.
