Javascript ClipPath和SVG缩放

Javascript ClipPath和SVG缩放,javascript,svg,Javascript,Svg,我试图得到一个缩放的svg图像来剪辑模式,如果它在蓝色容器的外面。但是,当我将剪辑路径应用于完全相同位置的图案时。模式的X和Y位置发生变化,并最终位于容器外部,如下图所示,适用于完全相同的位置和变换。我还应用了一个feMorphology过滤器来显示剪切路径的绘制位置 SVG(非剪裁) XML <svg id="SvgjsSvg1006" width="550" height="650" xmlns="http://w

唯一的区别是,我在第二个svg的图像标记中添加了clip path=“url”(“#svgjsclipath1019”),错误在于应用
变换
剪辑路径
属性的顺序<代码>变换
始终是最后一个操作,并且
剪辑路径
应用于未变换的元素

这个片段

<image xlink:href="..." x="-75" y="-75"
       transform="translate(278.34 410.34) scale(1.66 1.66)"
       clip-path="url(#SvgjsClipPath1019)" />

相当于

<g transform="translate(278.34 410.34) scale(1.66 1.66)">
    <image xlink:href="..." x="-75" y="-75"
           clip-path="url(#SvgjsClipPath1019)" />
</g>

虽然您希望实现这一目标:

<g clip-path="url(#SvgjsClipPath1019)">
    <image xlink:href="..." x="-75" y="-75"
       transform="translate(278.34 410.34) scale(1.66 1.66)"> />
