zhukoview

这是一个库，它提供了一种将一维 N*M u32 容器中的 2D '视图'，并提供了添加线条、圆、三角形和矩形的工具。Logo 是通过以下代码生成的

use pingus::*;
use zhukoview::{AntiAliasing, CanvasView, Colour};
// 4096 x 2160 4K
// 3024 x 1964 MBP 14"
const W: u32 = 32;
const H: u32 = 32;
const SIZE: usize = (W * H) as usize;
fn main() {
    let mut canvas = [0xFFFFB86C; SIZE];
    let mut imgbuf = [0; SIZE];
    let mainview = CanvasView::new(W, H);
    let subview = mainview.subview((4, 4), 24, 24).unwrap();
    let (a, b, c) = (
        (0, 0),
        ((subview.w >> 1) as isize, (subview.h - 1) as isize),
        ((subview.w - 1) as isize, (subview.h >> 1) as isize),
    );
    subview.fill(&mut canvas, 0xFF282A36);
    subview.add_triangle(

        (20, 25),
        (25, 20),
