Struct Screenshot 

pub struct Screenshot {
    pub width: u32,
    pub height: u32,
    pub pixels: Vec<u8>,
    pub scale: f32,
}
Expand description

A captured image: raw RGBA8 pixels plus dimensions and scale.

width and height are in physical pixels. scale is the ratio of physical to logical (1.0 on standard displays, 2.0 on typical Retina / 1.5/1.75/2.0 on common Windows/Linux HiDPI configurations). pixels.len() equals width * height * 4.
