Struct Image 

pub struct Image {
    pub width: u32,
    pub height: u32,
    pub data: Vec<u8>,
}

8-bit sRGB RGBA, straight alpha, row-major, no padding.

Fields

width: u32

Width in pixels.

height: u32

Height in pixels.

data: Vec<u8>

width * height * 4 bytes.

Implementations

impl Image

pub fn encode_png(&self) -> Vec<u8>

Encodes the image as PNG (8-bit RGBA, straight alpha).

Panics

If data is not width * height * 4 bytes — a bug in whoever built the image.

pub fn decode_png(bytes: &[u8]) -> Option<Image>

Reads an 8-bit RGBA or RGB PNG, such as one encode_png wrote. None for anything else or a broken file.
