Struct RasterBuf 

pub struct RasterBuf {
    pub width: u32,
    pub height: u32,
    pub pixels: Vec<u8>,
}

RGBA8 raster, sRGB color space, premultiplied alpha. Layout is row-major, four bytes per pixel [R, G, B, A].

Fields

width: u32

height: u32

pixels: Vec<u8>

Implementations

impl RasterBuf

pub fn new(width: u32, height: u32) -> Self

pub fn filled(width: u32, height: u32, rgba: [u8; 4]) -> Self

pub fn is_blank(&self) -> bool

Whether every byte is zero — i.e. fully transparent everywhere. For premultiplied RGBA this means no coverage and no color at all (a valid premultiplied pixel with a == 0 also has rgb == 0). Scans in u128-wide chunks, so a canvas-sized buffer costs only tens of microseconds.

pub fn pixel(&self, x: u32, y: u32) -> [u8; 4]

Trait Implementations
