SVG为何被切断，我该如何解决？

编码错误？

代码：https://jsfiddle.net/gxnaw2L8/

应如下所示：

但是，SVG看起来像这样。

我该如何解决？

我不明白问题是什么。

要我提供更多信息，但这就是整个问题，我提供了完整的代码。

1 个答案:

答案 0 :(得分：3)

您正在使用的是viewBox：viewbox="8.5 -12.2 7 48.49"正如您所看到的那样，内部图像的宽度只有7个单位，并且未绘制在viewBox外部的元素。另外，如果您正在使用符号，则将viewBox用于符号可能非常有用。在这种情况下，<symbol id="play" viewBox="1.25 1.25 21.5 21.5">

如果您使用的符号没有宽度和高度x和y属性，它将采用svg元素的宽度（第一个示例）

在第二个示例中，我使用<use href="#play" width="50%" height="50%" x="25%" y="25%" />，这意味着所使用的符号的大小为svg元素的一半，而左上角为25％

此外，由于symbol元素没有填充，因此您可以像fill="red"那样填充它。

为了知道要使用的viewBox值，我将元素包装在<g id="the_symbol">组中，并且在javascript我the_symbol.getBBox()中返回了SVGRect {x: 1.25, y: 1.25, width: 21.5, height: 21.5}，因此viewBox =“ xy宽度高度” 

viewBox="1.25 1.25 21.5 21.5"

请注意viewBox是驼峰案例视图 B ox
