class Graphics.Color

Represents color value with red, blue. green and alpha components.

Properties:​

r, g, b, a​

read-only, color channels as decimals in range [0.0 ... 1.0]

  • color.r - red channel.
  • color.g - green channel.
  • color.b - blue channel.
  • color.a - alpha channel, 0.0 - fully transparent, 1.0 - fully opaque.

R, G, B, A​

read-only, color channels as integer in range [0 ... 255]

  • color.R - read/only, int(0..255), red channel.
  • color.G - read/only, int(0..255), green channel.
  • color.B - read/only, int(0..255), blue channel.
  • color.A - read/only, int(0..255), alpha channel, 0.0 - fully transparent, 1.0 - fully opaque.

hsv​

read/only, reports [hue:0..360, saturation:0..1, value: 0..1, alpha: 0..1], HSV representation of the color.

const [h,s,v] = color.hsv;

hsl​

read/only, reports [hue:0..360, saturation:0..1, lightness: 0..1], HSL color representation.

const [h,s,l] = color.hsl;

Methods:​

toString()​

const ste = toString(type);

parameters:

  • type, string, representation type, one of:
    • "RGB" - returns "#RRGGBB"
    • "RGBA" - returns "#RRGGBBAA"
    • "rgb" - returns "rgb(255,255,255)"
    • "rgba" - returns "rgba(255,255,255,1.0)"

valueOf()​

color.valueOf()

returns integer of the color, packaged to uint32 as (a << 24) | (b << 16) | (g << 8) | (r)

Static methods:​

rgb()​

Color.rgb( r, g, b [,a]) : Color

constructs color instance from r,g,b,a components - float numbers in 0.0 .. 1.0 range.

RGB()​

Color.RGB(0..255,0..255,0..255[,0..255]) : Color

constructs color instance from r,g,b,a components - integes in 0...255 range.

hsv()​

Color.hsv( h, s, v [,a]) : Color

creates color instance from HSV components - float numbers in 0.0 .. 1.0 range but h is in 0.0 .. 360.0 range.

hsl()​

Color.hsl( h, s, l [,a]) : Color

creates color instance from HSL components - float numbers in 0.0 .. 1.0 range but h is in 0.0 .. 360.0 range.

morph()​

Color.morph(from:Color,to:Color,ratio:0...1):Color

Morph from color into to color value according to ratio. If ratio == 0.0 it returns from and if ratio == 1.0 it returns to value. Color morphing is done in premultipled color space.
