inherited
-
convert<
R> (R pixel, {required PixelFormat< R, void> from}) → P -
Converts a pixel
fromone another format tothisformat.inherited -
copyWith(
P pixel, {C? gray}) → P -
Returns a copy of the
pixel.override -
copyWithNormalized(
P pixel, {double? gray}) → P -
Returns a copy of the
pixelwith normalized values.override -
create(
{C? gray}) → P - Creates a new pixel with the given channel values.
-
createNormalized(
{double gray = 0.0}) → P -
Creates a new pixel with the given channel value normalized to the range
[0.0, 1.0]. -
describe(
P pixel) → String -
