虚线箭头填充颜色

Dashed Arrow Head Filled With Color

我使用 konvajs 使用虚线创建 Konva.Arrow 形状。但是,箭头未填充颜色。如何让箭头有颜色?

这是我用来制作箭头的代码的基础。

lineConfig['dash'] = [12, 8];
lineConfig['points'] = [pos.x, pos.y];
arrowLine = new Konva.Arrow(lineConfig);

也尝试将 fill 属性 添加到您的箭头中,例如 fill: 'black'。我试着在没有那个的情况下画一个箭头 属性,结果和你描述的一样。

这是工作示例:

<!DOCTYPE html>
<html>
  <head>
    <script src="https://unpkg.com/konva@7.2.5/konva.min.js"></script>
    <meta charset="utf-8" />
    <title>Konva Arrow Demo</title>
    <style>
      body {
        margin: 0;
        padding: 0;
        overflow: hidden;
        background-color: #f0f0f0;
      }
    </style>
  </head>
  <body>
    <div id="container"></div>
    <script>
      var width = window.innerWidth;
      var height = window.innerHeight;

      var stage = new Konva.Stage({
        container: "container",
        width: width,
        height: height
      });

      var layer = new Konva.Layer();

      var arrow = new Konva.Arrow({
        x: stage.width() / 4,
        y: stage.height() / 4,
        points: [0, 0, 10, 100],
        pointerLength: 20,
        dash: [12, 8],
        pointerWidth: 20,
        // Comment the following line to get your issue
        fill: "black",
        stroke: "black",
        strokeWidth: 4
      });

      // add the shape to the layer
      layer.add(arrow);

      // add the layer to the stage
      stage.add(layer);
    </script>
  </body>
