Struct arboard::ImageData

pub struct ImageData<'a> {
    pub width: usize,
    pub height: usize,
    pub bytes: Cow<'a, [u8]>,
}

Stores pixel data of an image.

Each element in bytes stores the value of a channel of a single pixel. This struct stores four channels (red, green, blue, alpha) so a 3*3 image is going to be stored on 3*3*4 = 36 bytes of data.

The pixels are in row-major order meaning that the second pixel in bytes (starting at the fifth byte) corresponds to the pixel that’s sitting to the right side of the top-left pixel (x=1, y=0)

Assigning a 2*1 image would for example look like this

use arboard::ImageData;
use std::borrow::Cow;
let bytes = [
    // A red pixel
    255, 0, 0, 255,

    // A green pixel
    0, 255, 0, 255,
];
let img = ImageData {
    width: 2,
    height: 1,
    bytes: Cow::from(bytes.as_ref())
};

Fields

width: usize

height: usize

bytes: Cow<'a, [u8]>

Implementations

impl<'a> ImageData<'a>

pub fn into_owned_bytes(self) -> Cow<'static, [u8]>

Returns a the bytes field in a way that it’s guaranteed to be owned. It moves the bytes if they are already owned and clones them if they are borrowed.

pub fn to_owned_img(&self) -> ImageData<'static>

Returns an image data that is guaranteed to own its bytes. It moves the bytes if they are already owned and clones them if they are borrowed.

Trait Implementations

impl<'a> Clone for ImageData<'a>

fn clone(&self) -> ImageData<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ImageData<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
