Function rgb2yuv420::convert_rgb_to_yuv420
[−]
[src]
pub fn convert_rgb_to_yuv420(
img: &[u8],
width: u32,
height: u32,
bytes_per_pixel: usize
) -> Vec<u8>
Converts an RGB image to YUV420
img
should contain the pixel data in the following format
[r, g, b, ... , r, g, b, ... , r, g, b, ...]
bytes_per_pixel
should contain the number of bytes used by one pixel
eg.: RGB is 3 bytes and RGBA is 4 bytes
Examples
let rgb = vec![0u8; 12]; let yuv = rgb2yuv420::convert_rgb_to_yuv420(&rgb, 2, 2, 3); assert_eq!(yuv.len(), rgb.len() / 2);
