lstarFromArgb static method

double lstarFromArgb(
  1. int argb
)

Computes the L* value of a color in ARGB representation.

argb ARGB representation of a color Returns L*, from Lab*, coordinate of the color

Implementation

static double lstarFromArgb(int argb) {
  final y = xyzFromArgb(argb)[1];
  return 116.0 * _labF(y / 100.0) - 16.0;
}
