Spriterator

Spriterator is a Rust library that creates sprite sheets by combining multiple images from a specified directory into a compact format.

Example

The following example demonstrates how to use Spriterator to create sprite sheets from images in a directory.

use spriterator::Spriterator;
use std::fs;
use std::path::Path;

fn prepare_directory(path: &str) -> std::io::Result<()> {
    let dir_path = Path::new(path);

    if dir_path.exists() {
        fs::remove_dir_all(dir_path)?;
    }

    fs::create_dir_all(dir_path)?;

    Ok(())
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let ext = "png";
    let output_dir = format!("/parth/to/sprites/{}", ext);
    
    prepare_directory(output_dir.as_str())?;

    let size = 1024;
    let spriterator = Spriterator::new(
        format!("/parth/to/images/{}", ext).as_str(),
        size,
        size,
    );
    let sprites = spriterator.generate()?;

    for (index, sprite) in sprites.iter().enumerate() {
        sprite.save(format!("{}/{}.{}", output_dir, index, ext))?;
    }

    Ok(())
}
