像素画布

该库旨在通过像素缓冲区轻松构建交互式计算机艺术。为了获得灵感，可以考虑查看 https://shadertoy.com 和 http://www.iquilezles.org/www/index.htm，那里有很多有趣的艺术作品和技巧的解释！

使用方法

要制作一件艺术品，您需要创建和配置一个 Canvas 对象，然后请求它使用您的代码进行 render。画布将进行状态管理，并给您一个可以修改的图像。您对图像所做的任何修改都将显示在屏幕上。

示例

use pixel_canvas::{Canvas, Color, input::MouseState};

fn main() {
    // Configure the window that you want to draw in. You can add an event
    // handler to build interactive art. Input handlers for common use are
    // provided.
    let canvas = Canvas::new(512, 512)
        .title("Tile")
        .state(MouseState::new())
        .input(MouseState::handle_input);
    // The canvas will render for you at up to 60fps.
    canvas.render(|mouse, image| {
        // Modify the `image` based on your state.
        let width = image.width() as usize;
        for (y, row) in image.chunks_mut(width).enumerate() {
            for (x, pixel) in row.iter_mut().enumerate() {
                let dx = x as i32 - mouse.x;
                let dy = y as i32 - mouse.y;
                let dist = dx * dx + dy * dy;
                *pixel = Color {
                    r: if dist < 128 * 128 { dy as u8 } else { 0 },
                    g: if dist < 128 * 128 { dx as u8 } else { 0 },
                    b: (x * y) as u8,
                }
            }
        }
    });
}
