Trait ImageSource 

pub trait ImageSource {
    // Required methods
    fn span(&mut self, x: i32, y: i32, len: u32) -> &[u8] ;
    fn next_x(&mut self) -> &[u8] ;
    fn next_y(&mut self) -> &[u8] ;
}

Trait for image pixel sources used by span image filters.

All image accessor types implement this trait, providing a common interface for the span generators to read pixels.

Required Methods

fn span(&mut self, x: i32, y: i32, len: u32) -> &[u8]

Begin reading a span at (x, y) with len pixels. Returns first pixel.

fn next_x(&mut self) -> &[u8]

Advance to the next pixel in the x direction.

fn next_y(&mut self) -> &[u8]

Advance to the next row (y+1), resetting x to the span start.
