Variables ¶

var HexModel = color.ModelFunc(hexModel)

HexModel converts any Color to an Hex color.

Functions ¶

func HexToRGBA ¶

func HexToRGBA(h Hex) (r, g, b, a uint8)

Converts an Hex string to RGBA. If alpha is not specified, it defaults to 255 If it is not a valid hexadecimal number of the right width, a horrible yellow color is returned

Types ¶

type Hex ¶

type Hex string

Hex represents an RGB color in hexadecimal format.

The length must be 3 or 6 characters, preceded or not by a '#'.

func RGBAToHex ¶

func RGBAToHex(r, g, b, a uint8) Hex

RGBAToHex converts an RGBA to a Hex string. If a == 255, the A is not specified in the hex string

func (Hex) RGBA ¶

func (c Hex) RGBA() (uint32, uint32, uint32, uint32)

RGBA returns the alpha-premultiplied red, green, blue and alpha values for the Hex.
