Functions ¶

Types ¶

type LerpFn ¶ added in v0.0.8

type LerpFn func(c1, c2 colorful.Color, t float64) colorful.Color

var DefaultLerpFn LerpFn = colorful.BlendOklab

DefaultLerpFn is the function used by Lerp to interpolate between two colors.

type Point ¶

type Point struct {
	Col colorful.Color
	Pos float64
}

type Set ¶

type Set struct {
	// contains filtered or unexported fields
}

A Set is an ordered set of gradients. Set provides convenience methods such as picking a random gradient from a Set (Set.Rand()) and picking successive gradients from a Set (Set.Next()).

func NewSet ¶

func NewSet(gradients ...Table) Set

NewSet returns a new Set containing gradients.

func (Set) Idx ¶ added in v0.0.8

func (s Set) Idx(i int) Table

Idx returns the gradient at the ith position. Idx is syntax sugar for Index.

func (Set) Index ¶

func (s Set) Index(i int) Table

Index returns the gradient at the ith position. If i is out of range, i is "wrapped around" to bring it back in range.

func (Set) Next ¶

func (s Set) Next() Table

Next return successive gradients from the Set each time it is called, starting with the first gradient.

func (Set) Rand ¶

func (s Set) Rand() Table

Rand returns a random gradient from the Set.

type Table ¶

type Table []Point

Table represents a gradient and contains its "points". The position of each keypoint must lie in the range [0,1] and points must be sorted in ascending order.

func FromSet ¶

func FromSet(s colorful.Set) Table

FromSet creates a gradient from a colorful.Set.

func New ¶

func New(colors ...colorful.Color) Table

New returns a gradient with colors equidistant from each other.

func NewPingPong ¶

func NewPingPong(count int, colors ...colorful.Color) Table

NewPingPong returns a gradient consisting of: (1) colors in order; followed by (2) count copies of colors, alternating between:

(a) colors in reverse order, with the first color omitted; and
(b) colors in order, with the first color omitted.

func (Table) Boost ¶ added in v0.0.6

func (gt Table) Boost(m float64) Table

Boost returns a new gradient with each color's RGB value multiplied by m. Boost does not affect a color's A or position.

func (Table) Colors ¶

func (gt Table) Colors() []colorful.Color

Colors returns the gradient's colors as a slice of colorful.Colors.

func (Table) Lerp ¶

func (gt Table) Lerp(t float64) colorful.Color

Lerp returns interpolated color at t. By default, the interpolation is done in the Oklab colorspace. Change DefaultLerpFn to change the default. Use LerpIn to interpolate in a specific colorspace.

func (Table) LerpIn ¶ added in v0.0.8

func (gt Table) LerpIn(t float64, fn LerpFn) colorful.Color

LerpIn returns the interpolated color at t, with the interpolation done by fn.

func (Table) Reverse ¶

func (gt Table) Reverse() Table

Reverse returns a copy of the gradient with its colors' order reversed.

func (Table) Rotate ¶

func (gt Table) Rotate(n int) Table

Rotate returns a copy of the gradient with its colors rotated to the left by n.

func (Table) RotateRand ¶

func (gt Table) RotateRand() Table

RotateRand returns a new gradient rotated by a random number.

func (Table) Set ¶ added in v0.0.8

func (gt Table) Set() colorful.Set

Set returns the gradient's colors as a colorful.Set.

func (Table) ToSet deprecated

func (gt Table) ToSet() colorful.Set

ToSet returns the gradient's colors as a colorful.Set.

Deprecated: use Set() instead.
