Available on crate feature renderer-software only.
Expand description

Trait for the pixels in the buffer

Required Methods§

fn blend(&mut self, color: PremultipliedRgbaColor)

Blend a single pixel with a color

fn from_rgb(red: u8, green: u8, blue: u8) -> Self

Create a pixel from the red, gree, blue component in the range 0..=255

Provided Methods§

fn blend_slice(slice: &mut [Self], color: PremultipliedRgbaColor)

Blend a color to all the pixel in the slice.

fn from_rgb565(value: u16) -> Self

Create a pixel from a 16-bit RGB565 value in native byte order (5 red bits, 6 green bits, 5 blue bits).

The default implementation expands the components. RGB565 pixel types override this and use the value as-is.

fn background() -> Self

Pixel which will be filled as the background in case the slint view has transparency

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
