huepaper - a colorful wallpaper generator

huepaper creates wallpapers based on color hues. Bring a little color in your life by randomness, because every huepaper is truly unique.

You can find examples below.

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

usage: huepaper.py [-h] [-W WIDTH] [-H HEIGHT] [-c COLOR] [-p] [-o OUTPUT]
[-l [LINES]] [-lb [LINES_BRIGHT]] [-ld [LINES_DARK]]
[-P PIXELATE] [-e EMBLEM] [-hue HUE] [-smin SMIN]
[-smax SMAX] [-lmin LMIN] [-lmax LMAX]

Create wallpapers based on color hues.

optional arguments:
  -h, --help            show this help message and exit
  -W WIDTH, --width WIDTH
                        width of wallpaper (defaul: 1920)
  -H HEIGHT, --height HEIGHT
                        height of wallpaper (default: 1080)
  -c COLOR, --color COLOR
                        color, the wallpaper is generated from (uses a random
                        color if not given)
  -p, --preview         preview wallpaper
  -o OUTPUT, --output OUTPUT
                        file where to save the wallpaper to (default: None)
  -l [LINES], --lines [LINES]
                        include one to three random lines in base color with
                        given opacity in range [0, 1] (default: 0.1)
  -lb [LINES_BRIGHT], --lines_bright [LINES_BRIGHT]
                        include one to three bright random lines with given
                        opacity in range [0, 1] (default: 0.1)
  -ld [LINES_DARK], --lines_dark [LINES_DARK]
                        include one to three dark random lines with given
                        opacity in range [0, 1] (default: 0.1)
  -P PIXELATE, --pixelate PIXELATE
                        pixelate image (e.g. 42x42)
  -e EMBLEM, --emblem EMBLEM
                        emblem to add in the center of the wallpaper
  -hue HUE              maximum hue to differ from given color in range [0, 1]
                        (default: 0.1)
  -smin SMIN            minimum satisfaction for colors in range [0, 1]
                        (default: 0.2)
  -smax SMAX            maximum satisfaction for colors in range [0, 1]
                        (default: 1.0)
  -lmin LMIN            minimum luminance for colors in range [0, 1] (default:
                        0.2)
  -lmax LMAX            maximum luminance for colors in range [0, 1] (default:
                        0.9)

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

If you set the color via -c it is not guaranteed, that it is included in the huepaper. Colors, similar to the given one are chosen. You can specify how far the colors differ in the hue range with the -hue parameter. 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.

If you use the -e argument to specify an emblem, make sure it has the right size. It is not scaled or stretched, just placed in the center of the image. If you want an offset, e.g. put it in the left bottom corner, provide an emblem file with the size of the huepaper, transparent background and your emblem in the bottom left corner.

Examples

Please note, that every huepaper call generates a new random image. You will never get the same huepaper twice. You may like some and dislike others. Fiddle around with the options to find a result, you are happy with.
