lib.rs:

Pack small rectangles into a larger one. This is useful for creating texture atlases for the efficient GPU rendering.

Usage example:

use rect_packer::Packer;

let config = rect_packer::Config {
    width: 1024,
    height: 1024,

    border_padding: 5,
    rectangle_padding: 10,
};

let rectangles = [(50, 70), (350, 210), (255, 410)];

let mut packer = Packer::new(config);
for &(width, height) in &rectangles {
    if let Some(rect) = packer.pack(width, height, false) {
        println!("Rectangle is at position ({}, {}) within the encompassing rectangle",
            rect.x,
            rect.y);
    }
}
