Class methods

from_hex(hex : String)

Create a RGBA struct from a hex color string.

Formats:

  • "#rgb"
  • "#rrggbb"
  • "#argb"
  • "#aarrggbb"
Source
from_relative(r, g, b, a)

Create a RGBA struct from float values r, g, b, a ranging from 0.0 to 1.0.

{1.0, 0.0, 0.0, 0.5} would be the color red with an opacity of 50%.

Source
from_rgb_n(r, g, b, n)

Create a RGBA struct from n-bit red, green and blue values

Source
from_rgba_n(r, g, b, a, n)

Create a RGBA struct from n-bit red, green, blue and alpha values

Source

Instance methods

alpha
blue
green
mix(other, t)

Linear interpolation (mixing) of two colors. t ranges from 0.0 to 1.0.

a.mix(b, 0.0) == a
a.mix(b, 1.0) == b
Source
multiply(other : RGBA) : RGBA

Mix two colors by multiplying their values

Source
over(other : RGBA) : RGBA

Mix two colors by using Alhpa Compositing

Source
red
to_relative

Create a tuple {r, g, b, a}, each ranging from 0.0 to 1.0 from this color.

Source
to_rgb8

Create a 8-bit {r, g, b} tuple, the alpha component is just omitted.
