SVG进阶|SVG剪裁路径

SVG剪裁路径是指根据指定的路径或形状来剪裁SVG图形。应用了剪裁路径的SVG图形,在剪裁路径内部的图形可以被显示出来,在剪裁路径之外的图形会被隐藏。
剪裁路径的例子
下面是一个简单的SVG剪裁路径的例子:
-
-
- style="fill: #0000ff; clip-path: url(#clipPath); " />
- style="fill: #0000ff; clip-path: url(#clipPath); " />
这个例子定义了一个矩形的剪裁路径(
下面的左边图像是返回结果。右边的图像也是返回结果,但是它将剪裁路径一起显示出来了。

注意观察,只有在矩形剪裁路径内部的圆形才会被显示出来,之外的部分会被剪裁掉。
高级剪裁路径
你可以使用任何图形来作为剪裁路径。可以是圆形、椭圆、多边形或自定义路径。
在下面的例子中使用一条自定义路径来作为剪裁路径。这条剪裁路径会被应用到一个
-
-
- style="stroke: none; fill:#00ff00; clip-path: url(#clipPath3);"/>
在下面的右边的图像是返回结果,左边的图像是没有使用剪裁路径的矩形。

在组(GROUPS)中应用剪裁路径
我们可以对一组SVG图形使用剪裁路径。实现的方法是将所有的图形放到一个
-
-
-
- style="stroke: none; fill:#00ff00;"/>
在下面左边的图像是没有使用剪裁路径的图像。右边的图像是上面代码的返回结果。

文字剪裁路径
我们还可以使用文字来作为剪裁路径。使用SVG
-
This is a text
-
- style="stroke: none; fill:#00ff00;"/>
下面左边的图像没有使用剪裁路径。右边的图像使用了文字剪裁路径。
