class Colors::ColorValue
- Colors::ColorValue
- Reference
- Object
Overview
The value one primary color has out of a RGB color.
Defined in:
colors/color_value.crConstructors
- .new(value : UInt8 = MIN_INTENSITY)
-
.new(value : AnyNumber | ColorValue)
Create a
ColorValuefrom a number or another color value. -
.new(value : String = "0")
Create a
ColorValuefrom a string representation: either a hexadecimal numeric value between 0 and 255, or the words"full"or"off"which translate toMAX_INTENSITYandMIN_INTENSITY, respectively.

Constructor Detail
Create a ColorValue from a number or another color value.
Raises OverflowError if the value won't fit in a UInt8; I.E. if the
value is less than 0 or greater than 255, or not an integer; E.G. 3.0,
100u64, 255f64, or ColorValue::new(100u8) are acceptable
parameters, -1, 256u16, or 123.456 will throw.
Create a ColorValue from a string representation: either a
hexadecimal numeric value between 0 and 255, or the words "full" or
"off" which translate to MAX_INTENSITY and MIN_INTENSITY,
respectively.
Raises if the value isn't a valid base-16 integer which fits into 8 bits, unsigned.
