Types ¶

type HSVColor ¶

type HSVColor struct {
	H    uint16
	S, V uint8
}

HSVColor defines a color in the Hue-Saturation-Value scheme. Hue is a value [0 - 360) specifying the color Saturation is a value [0 - 255] specifying the strength of the color Value is a value [0 - 255] specifying the brightness of the color

func (HSVColor) RGBA ¶

func (h HSVColor) RGBA() (r, g, b, a uint32)

type HexPlane ¶

type HexPlane struct {
	Values []HexPoint
	Origin HexPoint
	Size   int
}

func NewHexBoard ¶

func NewHexBoard(qnt int) *HexPlane

type HexPoint ¶

type HexPoint [3]float64 // Q R S

func Cube_round ¶

func Cube_round(hex HexPoint) HexPoint

func Pixel_to_flat_hex ¶

func Pixel_to_flat_hex(p Point2D, size float64) HexPoint

func Pixel_to_pointy_hex ¶

Bounds returns the domain for which At can return non-zero color. The bounds do not necessarily contain the point (0, 0).

func (*LineSquare) ColorModel ¶

func (ln *LineSquare) ColorModel() color.Model

ColorModel returns the Image's color model.
