🍞 gLUTen

gLUTen is a LUT library written in Rust, for use in color correction and color grading applications. It has a Python interface that allows you to use gLUTen in scripts for tools like Maya, Blender, and other digital content creation (DCC) software.

🚧 gLUTen is a work in progress. Features are still due for the first Cargo release.

✨ Features

🔨 Generate LUTs

Use gLUTen to generate LUTs from a reference image. Here's the workflow:

Apply your color correction/grading on original.png.
Save the edited image as a PNG; make sure the sizes match with the original.
Import the image using Image::load_png.
Generate the LUT using Lut::build.
Save the LUT as a file using Lut::save.

Check out example code in Rust and Python below. 👇

🦀 Usage in Rust

use gluten::{Image, Lut, LutFormat};

fn main() {
    let image = Image::load_png("edited.png").unwrap();
    let lut = Lut::build(&image, None).unwrap();
    lut.save("lut.cube", LutFormat::CubeLut, 6, true, false)
        .unwrap();
}

🐍 Usage in Python

import gluten

image = gluten.Image.load_png("edited.png")
lut = gluten.Lut.build(image, title="Test")
lut.save("lut.cube", gluten.LutFormat.CubeLut, 6, True, False)

🦀 For Rust

cargo build

🐍 For Python

First, set up the Python virtual environment:

python -m venv .env
source .env/bin/activate
pip install maturin

Then use maturin to develop:

maturin develop

That's it! You can now use gLUTen.

$ python
>>> import gluten
>>> dir(gluten)
['Image', 'Lut', 'LutFormat', '__all__', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', 'gluten']
