Implementations

impl<T: Clone + Default> Image<T>

pub fn new(width: usize, height: usize) -> Result<Self>

Creates a new image filled with the default value.

pub fn from_vec(data: Vec<T>, width: usize, height: usize) -> Result<Self>

Creates a new image from existing data.

impl<T> Image<T>

pub fn width(&self) -> usize
