Struct Color 

pub struct Color(pub u8, pub u8, pub u8, pub u8);

RGBA color used by the renderer.

Tuple Fields

0: u8

Red component in the range 0..=255.

1: u8

Green component in the range 0..=255.

2: u8

Blue component in the range 0..=255.

3: u8

Alpha component in the range 0..=255.

A value of 255 is fully opaque and 0 is fully transparent.

Implementations

impl Color

pub fn to_argb8888(self) -> u32

Convert this color to a packed ARGB8888 integer.

Used by display backends in the rlvgl-platform crate.

pub fn lerp(self, to: Color, num: i32, den: i32) -> Color

Integer linear interpolation from self toward to by num / den.

Each channel is interpolated as a + (b - a) * num / den with integer math (truncation toward zero). Deterministic — no floats. Used by the anim pulse adapter.

pub fn with_alpha(self, opacity: u8) -> Color

Return a copy with the alpha channel multiplied by opacity.

Both the existing alpha and opacity are in 0..=255.
