不确定我是否正确地制定了标题,但问题来了。

我有一个云状的 SVG 路径,我想在 CSS 中使用 clip-path属性。

<path d="M46.9819755,61.8637972 C42.0075109,66.8848566 35.0759468,70 27.4091794,70 C12.2715076,70 0,57.8557238 0,42.875 C0,32.9452436 5.3914988,24.2616832 13.4354963,19.534921 C14.8172134,8.52285244 24.3072531,0 35.8087666,0 C43.9305035,0 51.0492374,4.2498423 55.01819,10.6250065 C58.2376107,8.87215568 61.9363599,7.875 65.8704472,7.875 C78.322403,7.875 88.4167076,17.8646465 88.4167076,30.1875 C88.4167076,32.1602271 88.1580127,34.0731592 87.6723639,35.8948845 L87.6723639,35.8948845 C93.3534903,38.685457 97.2583784,44.4851888 97.2583784,51.1875 C97.2583784,60.6108585 89.5392042,68.25 80.0171204,68.25 C75.4841931,68.25 71.3598367,66.5188366 68.2822969,63.6881381 C65.5613034,65.4654463 62.3012892,66.5 58.7971106,66.5 C54.2246352,66.5 50.0678912,64.7384974 46.9819755,61.8637972 Z" fill="lightblue" />

当我在 HTML 中添加一个 SVG 元素并定义 <clipPath> 时使用该路径,浏览器将剪切路径定位在左上角。如果我对被剪裁的元素应用边距,则掩码不会链接并保持在其初始位置。

其他类似的线程指出 clipPathUnits="objectBoundingBox"属性应添加到 <clipPath>对象,但这似乎并不能解决我的问题。我什至将路径从绝对路径转换为相对路径并尝试过,但得到了相同的结果。

是否有可能以某种方式将剪切路径与被剪切的元素链接起来,以便在将定位应用于被剪切的元素时,剪切路径也会移动?

这里是相对路径,如果有帮助的话:

<path d="M46.9819755,61.8637972c-4.974,5.021,-11.906,8.136,-19.573,8.136c-15.137,0,-27.409,-12.144,-27.409,-27.125c0,-9.93,5.392,-18.613,13.436,-23.34c1.381,-11.012,10.871,-19.535,22.373,-19.535c8.122,0,15.24,4.25,19.209,10.625c3.22,-1.753,6.918,-2.75,10.852,-2.75c12.452,0,22.547,9.99,22.547,22.313c0,1.972,-0.259,3.885,-0.745,5.707l0,0c5.682,2.791,9.586,8.59,9.586,15.293c0,9.423,-7.719,17.062,-17.241,17.062c-4.533,0,-8.657,-1.731,-11.735,-4.562c-2.721,1.778,-5.981,2.812,-9.485,2.812c-4.572,0,-8.729,-1.761,-11.815,-4.636z fill="lightblue" />

以及一些测试 HTML/CSS。 (我已将 left 属性设置为 10px,以便您看到出现剪辑问题)

最佳答案

感谢 Robert's comment ,我能够解决我遇到的问题。

这是我用来将绝对路径转换为相对路径的 PHP 片段,因此值介于 0 和 1 之间。

$absolute_path = "M46.9819755,61.8637972 C42.0075109,66.8848566 35.0759468,70 27.4091794,70 C12.2715076,70 0,57.8557238 0,42.875 C0,32.9452436 5.3914988,24.2616832 13.4354963,19.534921 C14.8172134,8.52285244 24.3072531,0 35.8087666,0 C43.9305035,0 51.0492374,4.2498423 55.01819,10.6250065 C58.2376107,8.87215568 61.9363599,7.875 65.8704472,7.875 C78.322403,7.875 88.4167076,17.8646465 88.4167076,30.1875 C88.4167076,32.1602271 88.1580127,34.0731592 87.6723639,35.8948845 L87.6723639,35.8948845 C93.3534903,38.685457 97.2583784,44.4851888 97.2583784,51.1875 C97.2583784,60.6108585 89.5392042,68.25 80.0171204,68.25 C75.4841931,68.25 71.3598367,66.5188366 68.2822969,63.6881381 C65.5613034,65.4654463 62.3012892,66.5 58.7971106,66.5 C54.2246352,66.5 50.0678912,64.7384974 46.9819755,61.8637972 Z";
function regex_callback($matches) {
static $count = -1;
$count++;
$width = 98;
$height = 70;
if($count % 2) {
return $matches[0] / $height;
} else {
return $matches[0] / $width;
}
}

$relative_path = preg_replace_callback('(\d+(\.\d+)?)', 'regex_callback', $absolute_path);

由于剪切路径不是矩形,我无法将值除以一个数字,而是必须使用剪切路径本身的宽度和高度。
