# huepaper

**huepaper** creates wallpapers based on color hues.

## Installation

Until now there is no install method, just ways to call the script.

### NixOS

Call `nix-shell` in the project directory. This will drop you into a
python environment with all necessary requirements.

### LegacyOS

Install the python requirements with `pip install -r requirements.txt`.

## Usage

    [-P PIXELATE] [-e EMBLEM] [-hue HUE] [-smin SMIN]
    [-smax SMAX] [-lmin LMIN] [-lmax LMAX]

                            0.9)

All image operations are called in order of the help file. E.g. pixelate
(`-P`) is called after adding lines (`-l`).

Valid color expressions are e.g. `#F5F5DC`, `#0f0`, `red`.
Make sure, that colors beginning with a `#` are encapsulated in quotes (`"`).
All supported color names can be seen [here](https://www.w3schools.com/colors/colors_names.asp).
