Struct Pixmap

Source

pub struct Pixmap {
    pub width: u32,
    pub height: u32,
    pub data: Vec<u8>,
}

Expand description

An RGBA8 raster image with straight (non-premultiplied) alpha, row-major from the top-left.

Fields§

§width: u32§height: u32§data: Vec<u8>

Pixel data, width * height * 4 bytes (RGBA per pixel).

Implementations§
