Methods
impl Color[src]
pub fn is_valid(&self) -> bool[src]
Returns true if the values for each field are valid.
The documentation above lists the valid range for each field.
pub fn opaque(self) -> Color[src]
Return a new color with all of the same values except with opacity (alpha) set to 1.0
use turtle::Color; let color = Color {red: 43.0, green: 79.0, blue: 23.0, alpha: 0.5}; assert_eq!(color.alpha, 0.5); let color2 = color.opaque(); assert_eq!(color.alpha, 0.5); assert_eq!(color2.alpha, 1.0);
pub fn transparent(self) -> Color[src]
Return a new color with all of the same values except with opacity (alpha) set to 0.0
use turtle::Color; let color = Color {red: 43.0, green: 79.0, blue: 23.0, alpha: 0.5}; assert_eq!(color.alpha, 0.5); let color2 = color.transparent(); assert_eq!(color.alpha, 0.5); assert_eq!(color2.alpha, 0.0);
pub fn with_alpha(self, alpha: f64) -> Color[src]
Return a new color with alpha set to the given value
use turtle::Color; let color = Color {red: 43.0, green: 79.0, blue: 23.0, alpha: 0.5}; assert_eq!(color.alpha, 0.5); let color2 = color.with_alpha(0.2); assert_eq!(color.alpha, 0.5); assert_eq!(color2.alpha, 0.2);
