Starsheet

Generate pleasing images of a sky that doesn't exist.

A library and a cli binary.

The Future: A GUI, eventually, for fun!

Binary

Install with cargo install starsheet and then run with starsheet.

Currently, only PNGs will be output. You can change the --width with the -w flag, and the --height with -h. The amount of stars that are generated is a sort of density. The density, or number of --stars per 100 square pixels, can be changed with the -s option. I find that a good density is around 20.

Here is an example of a 1000x1000 image with a density of 20. The command looked like this:
starsheet -w 1000 -h 1000 -s 20 example

There is currently no way to change the percentages of the stars brightness, but this is coming!

Library

The documentation is currently not too great! Good thing there's only one struct with like 5 methods. Documentation will be improved. Until then, you can have a look at the binary source here, or the example below.

use starsheet::Space;

// Generates an image with the same parameters as the example image
fn main() {
	// Create a new Space struct with a width and height of 1000 pixels
	let mut space = Space::new(1000, 1000);
	// Fill space randomly with stars at a density of 20 stars per 100 pixels^2
    space.fill_randomly(20);
	
	// Get the width and height from space
    let width = space.width();
	let height = space.height();
	
	// Consume space and get the underlying pixel data. Each u8 is a black
	// level, so the image is greyscale.
	let data = space.to_data();
	
	// ... From here you can manipulate the image further by operating on the
	// pixel data or feed it to some kind of image encoder to write as a file.
