type Coloring 

type Coloring struct {
	Grad iro.Gradient
	// contains filtered or unexported fields
}

Coloring contains information on how to color a fractal.

func NewColoring 

func NewColoring(base iro.Color, mode Mode, colors []iro.Color, stops []float64) *Coloring

NewColoring pre-calculates gradients.

func (*Coloring) Get 

func (c *Coloring) Get(i int64, it int64) (float64, float64, float64)

Get returns red, green and blue values from the current iteration i and the max iteration it.

func (*Coloring) Mode

Mode returns the coloring mode.

func (*Coloring) String 

func (c *Coloring) String() string

type Mode 

type Mode int

Mode determines the coloring method. 

const (
	// Modulo determines the coloring scheme based on the modulo of the iteration.
	Modulo Mode = iota
	// IterationCount determines the coloring scheme based on the length of the orbit.
	IterationCount
	// OrbitLength colors the orbit in a gradient from beginning to end.
	OrbitLength
	// VectorField colors the angles between the points in an orbit.
	VectorField
	// Path linearly interpolates between the points in the path.
	Path
)
