Crate rect_packer

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);
    }
}

Structs

Config

Describes size and padding requirements of rectangle packing.

DensePacker

Similar to Packer but does not add any padding between rectangles.

Packer

Packer is the main structure in this crate. It holds packing context.

Rect
