Struct YUVBuffer 

pub struct YUVBuffer { /* private fields */ }

Converts RGB to YUV data.

Implementations

impl YUVBuffer

pub fn from_vec(yuv: Vec<u8>, width: usize, height: usize) -> Self

Creates a new YUV buffer from the given vec.

The vec’s length should be 3 * (width * height) / 2.

Panics

May panic if the given sizes are not multiples of 2, or the yuv buffer’s size mismatches.

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

Allocates a new YUV buffer with the given width and height.

Both dimensions must be even.

Panics

May panic if the given sizes are not multiples of 2.

pub fn from_rgb_source(rgb: impl RGBSource) -> Self

Allocates a new YUV buffer with the given width and height and data.

Panics

May panic if invoked with an RGB source where the dimensions are not multiples of 2.

pub fn from_rgb8_source(rgb: impl RGB8Source) -> Self

Allocates a new YUV buffer with the given width and height and data.

This is the faster version of Self::from_rgb_source and you should generally use this one.

Panics

May panic if invoked with an RGB source where the dimensions are not multiples of 2.

pub fn read_rgb(&mut self, rgb: impl RGBSource)

Reads an RGB buffer, converts it to YUV and stores it.

Panics

May panic if the given rgb does not match the internal format.

pub fn read_rgb8(&mut self, rgb: impl RGB8Source)

Reads an RGB8 buffer, converts it to YUV and stores it.

This is the faster version of Self::read_rgb and you should generally use this one.

Panics

May panic if the given rgb does not match the internal format.

Trait Implementations

impl YUVSource for YUVBuffer

fn dimensions(&self) -> (usize, usize)
