Struct nannou::draw::background::Background

pub struct Background<'a> { /* private fields */ }

A type used to update the background colour.

Implementations

impl<'a> Background<'a>

pub fn color<C>(self, color: C) -> Self

where C: IntoLinSrgba<ColorScalar>,

Clear the background with the given color.

This method supports any color type that can be converted into RGBA.

Colors that have no alpha channel will be given an opaque alpha channel value 1.0.

pub fn rgb(self, r: ColorScalar, g: ColorScalar, b: ColorScalar) -> Self

Specify the color via red, green and blue channels.

pub fn rgba( self, r: ColorScalar, g: ColorScalar, b: ColorScalar, a: ColorScalar ) -> Self

Specify the color via red, green, blue and alpha channels.

pub fn hsl(self, h: ColorScalar, s: ColorScalar, l: ColorScalar) -> Self

Specify the color via hue, saturation and luminance.

If you’re looking for HSV or HSB, use the hsv method instead.

The given hue expects a value between 0.0 and 1.0 where 0.0 is 0 degress and 1.0 is 360 degrees (or 2 PI radians).

See the wikipedia entry for more details on this color space.

pub fn hsla( self, h: ColorScalar, s: ColorScalar, l: ColorScalar, a: ColorScalar ) -> Self

Specify the color via hue, saturation, luminance and an alpha channel.

If you’re looking for HSVA or HSBA, use the hsva method instead.

The given hue expects a value between 0.0 and 1.0 where 0.0 is 0 degress and 1.0 is 360 degrees (or 2 PI radians).

See the wikipedia entry for more details on this color space.

pub fn hsv(self, h: ColorScalar, s: ColorScalar, v: ColorScalar) -> Self

Specify the color via hue, saturation and value (brightness).

This is sometimes also known as “hsb”.

The given hue expects a value between 0.0 and 1.0 where 0.0 is 0 degress and 1.0 is 360 degrees (or 2 PI radians).

See the wikipedia entry for more details on this color space.

pub fn hsva( self, h: ColorScalar, s: ColorScalar, v: ColorScalar, a: ColorScalar ) -> Self

Specify the color via hue, saturation, value (brightness) and an alpha channel.

This is sometimes also known as “hsba”.

The given hue expects a value between 0.0 and 1.0 where 0.0 is 0 degress and 1.0 is 360 degrees (or 2 PI radians).
