Struct ImageView 

pub struct ImageView<'a> {
    pub data: &'a [u8],
    pub width: usize,
    pub height: usize,
    pub origin: [i32; 2],
}

Minimal grayscale view for refinement without taking a dependency on image.

Fields

data: &'a [u8]

width: usize

height: usize

origin: [i32; 2]

Origin of the view in the coordinate system of the response map / base image.
