Ada

A 2D Shapes pixel rendering library in rust. Supported shapes are:

• Line2D
• Rectangle2D
• Ellipse2D
• Polygon2D
• Bezier2D [Both quadratic and cubic]

No use of unsafe blocks. #![forbid(unsafe_code)] is also declared at crate level.

Usage

Add this to Cargo.toml file:

[dependencies]
ada = "0.2.0"

Example code:

use ada::{shape, Canvas};

const WIDTH: usize = 512;
const HEIGHT: usize = 512;

// create a pixel buffer for RGBA values
let mut buffer = vec![0u8; 4 * WIDTH * HEIGHT];

// create canvas
let mut canvas = Canvas::new(WIDTH, HEIGHT).unwrap();

// draw line
shape::draw_line2d(50, 50, 200, 300, canvas, &ada::color::WHITE, &mut buffer[..]);

// draw rectangle
shape::draw_rect2d(50, 100, 100, 150, canvas, &ada::color::RED, &mut buffer[..]); // hollow
shape::draw_rect2d_filled(50, 100, 90, 120, canvas, &ada::color::GREEN, &mut buffer[..]); // filled

You can find more examples for all shapes in examples folder. To run an example:

cargo run --example draw_hollow
