Struct libmosh::MoshCore

pub struct MoshCore {
    pub data: MoshData,
    pub options: MoshOptions,
}

Core container.

Holds image data and processing options.

Fields

data: MoshData

options: MoshOptions

Implementations

impl MoshCore

pub fn new() -> Self

Creates a new, empty instance of MoshCore with a random seed.

pub fn read_image(&mut self, input: &[u8]) -> Result<(), MoshError>

Reads provided image for future processing.

Errors

It may fail if an image is not a valid PNG file.

pub fn mosh(&mut self) -> Result<(), MoshError>

Processes an image with current settings, storing the result in a buffer.

Errors

• UnsupportedColorType: Indexed is not supported.

Example

use libmosh::{
    err::MoshError,
    ops::{read_file, write_file},
    MoshCore,
};

let input = read_file("src/util/test-rgb.png")?;
let output = "test.png";
let mut image = MoshCore::new();

image.options.min_rate = 5;
image.options.max_rate = 7;
image.options.pixelation = 10;
image.options.line_shift = 0.7;
image.options.reverse = 0.4;
image.options.flip = 0.3;
image.options.channel_swap = 0.5;
image.options.channel_shift = 0.5;
image.options.seed = 42;

image.read_image(&input)?;
image.mosh()?;
write_file(
    output,
    &image.data.buf,
    image.data.width,
    image.data.height,
    image.data.color_type,
    image.data.bit_depth,
)?;
