argbToRgb

Converts a 32-bit packed ARGB integer (as used by e.g. Chromium’s Local State profile background_color field) into a CSS rgb() string. The alpha byte (top 8 bits) is read but discarded — the result is always opaque.

Available since v3.0.0

Import

import { argbToRgb } from '@helpers4/color';
// or, from the all-in-one package (same code, one install):
import { argbToRgb } from 'helpers4/color';

Signature

argbToRgb(argb: number): string

Parameters

Parameter	Type	Description
argb	number	A 32-bit integer where bits 24-31 are alpha, 16-23 are red, 8-15 are green, and 0-7 are blue

Returns

string — A rgb(r,g,b) CSS color string

Examples

Convert a packed ARGB integer to a CSS color

The top byte (alpha) is discarded — the result is always opaque.

argbToRgb(0xffff0000)
// => 'rgb(255,0,0)'

Alpha byte does not affect the result

Two ARGB values differing only in the alpha byte produce the same rgb() string.

argbToRgb(0x00ff0000) === argbToRgb(0x80ff0000)
// => true
