[−][src]Struct nannou::color::Rgb
Linear RGB.
RGB is probably the most common color space, when it comes to computer graphics, and it's defined as an additive mixture of red, green and blue light, where gray scale colors are created when these three channels are equal in strength. This particular RGB type is based on the ITU-R BT.709 primaries, which makes it a linear version of sRGB.
Conversions and operations on this color space assumes that it's linear,
meaning that gamma correction is required when converting to and from a
displayable RGB, such as sRGB. See the pixel
module
for encoding types.
Fields
red: T
The amount of red light, where 0.0 is no red light and 1.0 is the highest displayable amount.
green: T
The amount of green light, where 0.0 is no green light and 1.0 is the highest displayable amount.
blue: T
The amount of blue light, where 0.0 is no blue light and 1.0 is the highest displayable amount.
Methods
impl<T> Rgb<T> where
T: Float,
[src]
T: Float,
pub fn new(red: T, green: T, blue: T) -> Rgb<T>
[src]
Linear RGB.
pub fn new_u8(red: u8, green: u8, blue: u8) -> Rgb<T>
[src]
Linear RGB from 8 bit values.
pub fn from_pixel<P>(pixel: &P) -> Rgb<T> where
P: RgbPixel<T>,
[src]
P: RgbPixel<T>,
Linear RGB from a linear pixel value.
pub fn to_pixel<P>(&self) -> P where
P: RgbPixel<T>,
[src]
P: RgbPixel<T>,
Convert to a linear RGB pixel. Rgb
is already assumed to be linear,
so the components will just be clamped to [0.0, 1.0] before conversion.
use palette::Rgb; let c = Rgb::new(0.5, 0.3, 0.1); assert_eq!((c.red, c.green, c.blue), c.to_pixel()); assert_eq!((0.5, 0.3, 0.1), c.to_pixel());

instead of other
. Read more
fn soft_light(self, other: Self) -> Self
[src]
Lighten other
if self
is light, or darken other
as if it's burned if self
is dark. The effect is increased if the components of self
is further from 0.5. Read more

Similar to difference
, but appears to result in a lower contrast. other
is inverted if self
is white, and preserved if self
is black. Read more
