我有一个小 svg 小部件,其目的是显示角度列表(见图)。

现在,角度是线条元素,只有描边,没有填充。但现在我想要一个“内部填充”颜色和一个“笔触/边框”围绕它。我猜线元素无法处理这个问题,那么我应该使用什么来代替呢?

请注意,线条笔划的 line-endcap 是圆角的。我想在解决方案中保持这种效果。

添加第二条线,坐标相同但线宽更细:

<g class="lsNorthAngleHandsContainer">
  <line data-angle="348" stroke="red" stroke-linecap="round" stroke-width="0.04" transform="rotate(348)" x1="0" x2="0" y1="0" y2="-0.4"/>
  <line data-angle="348" stroke="yellow" stroke-linecap="round" stroke-width="0.025" transform="rotate(348)" x1="0" x2="0" y1="0" y2="-0.4"/>

看起来你的线是不透明的,所以你可以在带有“外部”颜色的粗线顶部画一条带有“内部”颜色的细线。

我发现了一个优雅的解决方案,灵感来自W3C 关于填充和抚摸的文章的插图。基本上,您将路径移动到定义并使用此定义来绘制两个元素:

<svg width="200" height="200" viewBox="0 0 100 100">
    <defs>
        <line id="line1" x1="25" x2="75" y1="25" y2="75"/>
    </defs>
    <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#line1" class="stroke"></use>
    <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#line1" class="line"></use>
</svg>

通过使用<defs>and<use>您可以仅更改路径元素以更新两行。JSFiddle演示

您可以使用带圆角的矩形,但数学会发生一些变化:

  <rect data-angle="348" stroke="red" stroke-linecap="round" stroke-width="0.02" fill="#FF0" transform="rotate(348, 0, 0)" x="-0.02"  y="-0.4" width=".06" height=".4" rx=".03" ry=".03"/>

您也可以使用路径来执行此操作,即使圆形位很棘手:

<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd" [
  <!-- I often use entities to be able to change lot of numbers at once in static SVG, also kind of makes the paths more readable.
       Obvisouly, if you're generating the path you can use the same variables in code to append to d -->
  <!ENTITY handFill "0.01">
  <!ENTITY handFill2 "0.02"><!-- Should be 2 * handFill to be centered -->
  <!ENTITY handStroke "0.005"><!-- Should be less than handFill2 to not hide fill -->
]>
