Struct Frame 

pub struct Frame {
    pub width: usize,
    pub height: usize,
    pub rgba: Vec<u8>,
}

A decoded picture: width * height RGBA pixels, rows top to bottom, fully opaque.

Fields

width: usize

height: usize

rgba: Vec<u8>

Implementations

impl Frame

pub fn pixel(&self, x: usize, y: usize) -> [u8; 4]

The RGBA of the pixel at (x, y).

pub fn mean(&self) -> [f32; 3]

The average RGB over the whole picture.

pub fn is_black(&self) -> bool

Whether the picture is (nearly) black all over: a fade-in or a title card’s gap, not a picture worth using as a thumbnail.

pub fn turned(self, turns: u8) -> Frame

The picture turned turns clockwise quarter turns.
