HTML5 canvas 正多边形教程

要使用 Konva 创建一个正多边形形状，我们可以实例化一个 Konva.RegularPolygon() 对象。

有关属性和方法的完整列表，请参见 RegularPolygon API 参考。

Vanilla

import Konva from 'konva';

const stage = new Konva.Stage({
  container: 'container',
  width: window.innerWidth,
  height: window.innerHeight
});

const layer = new Konva.Layer();
stage.add(layer);

const hexagon = new Konva.RegularPolygon({
  x: stage.width() / 2,
  y: stage.height() / 2,
  sides: 6,
  radius: 70,
  fill: 'red',
  stroke: 'black',
  strokeWidth: 4
});

layer.add(hexagon);

React

import { Stage, Layer, RegularPolygon } from 'react-konva';

const App = () => {
  return (
    <Stage width={window.innerWidth} height={window.innerHeight}>
      <Layer>
        <RegularPolygon
          x={window.innerWidth / 2}
          y={window.innerHeight / 2}
          sides={6}
          radius={70}
          fill="red"
          stroke="black"
          strokeWidth={4}
        />
      </Layer>
    </Stage>
  );
};

export default App;
