Color models an ARGB color with an alpha, red, green, and blue component between 0 and 255. Color is also a solid Brush.

Slots

alphaSource

Int alpha()

The alpha component from 0 to 255, where 255 is opaque and 0 is transparent.

argbSource

const Int argb

The ARGB components masked together: bits 31-24 alpha; bits 16-23 red; bits 8-15 green; bits 0-7 blue.

bSource

Int b()

The blue component from 0 to 255.

blackSource

static Color black := Color.make(0)

Constant for 0x00_00_00

blueSource

static Color blue := Color.make(255)

Constant for 0x00_00_ff

darkGraySource

static Color darkGray := Color.make(11119017)

Constant for 0xa9_a9_a9

equalsSource

override Bool equals(Obj? that)

Overrides sys::Obj.equals

Return argb as the hash code.

fromStrSource

static Color? fromStr(Str s, Bool checked := true)

Parse color from string (see toStr). If invalid and checked is true then throw ParseErr otherwise return null. The following formats are supported:

  • #AARRGGBB
  • #RRGGBB
  • #RGB

Examples:

Color.fromStr("#8A0")
Color.fromStr("#88AA00")
Color.fromStr("#d088aa00")
gSource

Int g()

The green component from 0 to 255.

graySource

static Color gray := Color.make(8421504)

Constant for 0x80_80_80

greenSource

static Color green := Color.make(65280)

Constant for 0x00_ff_00

hashSource

override Int hash()

Overrides sys::Obj.hash

Return argb as the hash code.

makeSource

new make(Int argb := 0, Bool hasAlpha := false)

Make a new instance with the ARGB components masked together: bits 31-24 alpha; bits 16-23 red; bits 8-15 green; bits 0-7 blue. If hasAlpha is false, then we assume the alpha bits are 0xFF.

orangeSource

static Color orange := Color.make(16753920)

Constant for 0xff_a5_00

purpleSource

static Color purple := Color.make(8388736)

Constant for 0x80_00_80

rSource

Int r()

The red component from 0 to 255.

redSource

static Color red := Color.make(16711680)

Constant for 0xff_00_00

rgbSource

Int rgb()

Get the RGB bitmask without the alpha bits.

toCssSource

Str toCss()

To a valid CSS color string.

toStrSource

override Str toStr()

Overrides sys::Obj.toStr

If the alpha component is 255, then format as "#RRGGBB" hex string, otherwise format as "#AARRGGBB" hex string.

whiteSource

static Color white := Color.make(16777215)

Constant for 0xff_ff_ff

yellowSource

static Color yellow := Color.make(16776960)

Constant for 0xff_ff_00
