Farba

A CPU graphics library written in pure Rust

The library is not concerned with displaying the image. It only fills up the memory with pixels. It's up to you what to do with those pixels.

The name is pronounced as "farba" (how its spelled) which is a Ukrainian word for "paint" ("фарба").

Examples

3D Cube

console $ cargo run --example 3d_cube --features="window"

Flag of Japan

console $ cargo run --example flag_of_japan --features="image"

```rust use farba::{Canvas, RGBAColor};

const CANVASWIDTH: usize = 900; const CANVASHEIGHT: usize = 600;

fn main() { let mut canvas = Canvas::new(CANVASWIDTH, CANVASHEIGHT);

// Taken from https://upload.wikimedia.org/wikipedia/en/9/9e/Flag_of_Japan.svg
canvas.fill(RGBAColor::WHITE);
canvas.circle(
    (CANVAS_WIDTH / 2) as i32,
    (CANVAS_HEIGHT / 2) as i32,
    180,
    RGBAColor::from_rgb(0xBC, 0x00, 0x2D),
);

canvas.save_to_file("./examples/flag_of_japan.png");

}

```

Rectangles

console $ cargo run --example rectangle --features="image"

```rust use farba::{Canvas, RGBAColor};

fn main() { let mut canvas = Canvas::new(400, 400);

canvas.fill(RGBAColor::WHITE);

// Left eye
canvas.rect(80, 80, 30, 80, RGBAColor::BLACK);

// Right eye
canvas.rect(290, 80, 30, 80, RGBAColor::BLACK);

// Mouth
canvas.rect(80, 260, 30, 60, RGBAColor::BLACK);
canvas.rect(290, 260, 30, 60, RGBAColor::BLACK);
canvas.rect(80, 290, 240, 30, RGBAColor::BLACK);

canvas.save_to_file("./examples/rectangle.png");

} ```
