<static> unpackPixel(rgba, out, hsl, hsv) → {object}

Unpacks the r, g, b, a components into the specified color object, or a new object, for use with Int32Array. If little endian, then ABGR order is used when unpacking, otherwise, RGBA order is used. The resulting color object has the r, g, b, a properties which are unrelated to endianness.

Note that the integer is assumed to be packed in the correct endianness. On little-endian the format is 0xAABBGGRR and on big-endian the format is 0xRRGGBBAA. If you want a endian-independent method, use fromRGBA(rgba) and toRGBA(r, g, b, a).

Parameters:
Name Type Argument Default Description
rgba number

The integer, packed in endian order by packPixel.
out object <optional>

An object into which 3 properties will be created: r, g and b. If not provided a new object will be created.
