Functions

func GrayImageEqual

func GrayImageEqual(a, b *image.Gray) bool

GrayImageEqual returns true if the parameter images a and b match or false if otherwise.

func RGBAImageEqual

func RGBAImageEqual(a, b *image.RGBA) bool

RGBAImageEqual returns true if the parameter images a and b match or false if otherwise.

func RGBASlicesEqual

func RGBASlicesEqual(a, b []color.RGBA) bool

RGBASlicesEqual returns true if the parameter RGBA color slices a and b match or false if otherwise.

func RGBAToString

func RGBAToString(img *image.RGBA) string

RGBAToString returns a string representation of the Hex values contained in an image.RGBA.

func Rank

func Rank(c color.RGBA) float64

Rank a color based on a color perception heuristic.

func SortRGBA

func SortRGBA(data []color.RGBA, min, max int)

SortRGBA sorts a slice of RGBA values. Parameter min and max correspond to the start and end slice indicies that determine the range to be sorted.
