describe method
- int pixel
 
inherited
    Returns a human-readable description of the pixel.
This is used in the default implementation of Buffer.toString.
It is preferred that the result values are padded to a fixed width, and
that the result is a single line; for example, 0x12345678 or [0.1, 0.2, 0.3, 0.4].
Implementation
@override
String describe(int pixel) {
  return '0x${pixel.toRadixString(16).padLeft(max.bitLength ~/ 4, '0')}';
}
