Enum embedded_graphics::pixelcolor::BinaryColor

pub enum BinaryColor {
    Off,
    On,
}

Binary color.

BinaryColor is used for displays and images with two possible color states.

The interpretation of active and inactive states can be different for different types of displays. A BinaryColor::On might represent a black pixel on an LCD and a white pixel on an OLED display.

To simplify the conversion from BinaryColor to RGB and grayscale color types the default conversions assume that BinaryColor::Off is black and BinaryColor::On is white.

Conversion between BinaryColor and bool

use embedded_graphics::pixelcolor::BinaryColor;

// A BinaryColor can be converted to a bool by using the is_on and is_off methods.
let color = BinaryColor::On;
assert!(color.is_on());
assert!(color.invert().is_off());

// BinaryColor implements From<bool>.
let bool_value = true;
let color: BinaryColor = bool_value.into();
assert_eq!(color, BinaryColor::On);

// this is equivalent to:
let bool_value = true;
let color = if bool_value {
    BinaryColor::On
} else {
    BinaryColor::Off
};
assert_eq!(color, BinaryColor::On);

Variants

Off

Inactive pixel.

On

Active pixel.

Implementations

impl BinaryColor

pub fn invert(self) -> BinaryColor

Inverts the color.

Examples

use embedded_graphics::pixelcolor::BinaryColor;

assert_eq!(BinaryColor::Off.invert(), BinaryColor::On);
assert_eq!(BinaryColor::On.invert(), BinaryColor::Off);

pub fn is_on(self) -> bool

Returns true if this color is On.

Examples

use embedded_graphics::pixelcolor::BinaryColor;

assert!(BinaryColor::On.is_on());

pub fn is_off(self) -> bool

Returns true if this color is Off.

Examples

use embedded_graphics::pixelcolor::BinaryColor;

assert!(BinaryColor::Off.is_off());
