【中文标题】svg 剪辑图像并显示中风【英文标题】:svg clip image and show stroke 【发布时间】:2012-10-07 11:13:22 【问题描述】:

嗨,我是这个网站的新手,所以如果我不清楚我要做什么,请原谅我

我的问题是:-

我正在使用 html5 和 SVG 来剪辑图像,以便仅显示剪辑/多边形形状内部的图像部分,而多边形形状之外的任何部分都是不可见/被剪辑的

我还希望为多边形形状添加笔触宽度和颜色

我正在使用的 SVG 代码:-

上面提到的代码工作正常,它显示的是一个具有多边形形状的图像,只有落在形状内的图像部分被显示,而任何落在形状外的部分被隐藏

但不知何故,我尝试了各种方法,但仍然无法显示笔触/边框。

我的问题是如何在用于剪辑图像的多边形上显示边框/笔触

提前致谢

【问题讨论】:

上面提到的代码将在多边形形状内剪辑或显示图像,我想做的是为这个多边形形状添加边框 【参考方案1】:

这里您使用的是 SVG 中的图像,但如果假设您在 html 代码中的图像上使用剪辑路径,您将无法以这种方式为其设置边框。 为了实现这一点,您也可以将剪辑路径应用到图像的容器 div,然后为其设置相同颜色的背景和边框。

【讨论】:

【参考方案2】:

首先请用小写字母填写ID,以使剪辑路径正常工作:&lt;clipPath id="SVGID_1_"&gt;

其次,只需复制您的路径以便使用常规形状。

或者,您可以将路径定义为形状,然后仅引用其名称:

谢谢!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!! 它工作得很好,我是 svg 的新手,两天前才知道它,你能推荐一个网站或一本书,可以教我从基础到高级,再次非常感谢,我几乎确信我永远无法做到这一点,而且我的雇主正在寻找可以在不使用 Flash 的情况下以 3D 格式渲染图像的人,如果您有兴趣,您看起来像专家,我可以联系您 :) 我的荣幸!不,我的教程是“问题+谷歌”。我也喜欢利用现有文件并通过更改它们来学习。也许只是搜索“svg tutorial” 感谢您的提议,但我认为去我的工作场所旅行超过 5000 公里是不值得的! :o)

以上是关于svg 剪辑图像并显示中风的主要内容,如果未能解决你的问题,请参考以下文章
