html - 如何在没有 div 的情况下通过 css 将图像放在内联 svg 之上？

转载作者：行者123 更新时间：2023-12-04 11:29:55

我有一个由 javascript 生成并内嵌在 HTML 页面中的 svg。在一些六边形(SVG 中定义的多边形)的顶部(上方，更高的 z-index)我想显示一个图像。
我能够添加一个 div，其中包含具有 css 绝对位置和顶部/左侧/宽度(以像素为单位)的图像。
但是，对于我必须显示的数据，这意味着为 39 个不同的图像添加 473 div(大约 10k 中的 473 个多边形需要一个图像、74 行和 134 列十六进制)。图像代表世界地图，六 Angular 形可以有大约 40 种不同的颜色。你可以看到here .
我想知道是否有解决方案可以使该图像出现在十六进制顶部，最好是在 svg 或 css 中？喜欢为多边形添加一个类，还是一个样式？
我曾尝试为多边形添加样式并为其提供背景图像，将图像包含在多边形内，但多边形的颜色优先于顶部。
这是代码:

由于 div 解决方案，第一行的第一个多边形上面有图像

第二行的最后一个多边形，CSS 将颜色更改为橙色，但未能在橙色顶部添加图像(甚至填充:无!？)

以下是问题的更新，建议通过 <defs><pattern ...><image ...> 提出解决方案。
谢谢@景贤!!
这是通过 CSS 显示图像而不重复的解决方案:
(宽度必须与多边形宽度匹配)

但仍然存在一个问题:如果图像以这种方式显示，多边形的背景颜色就会消失(尽管 PNG 是透明的)。

MXDVL 提出:在模式中添加一个矩形。
但是该矩形出现在图像上方，而不是下方。另外，我有 30 种不同颜色的六边形和 39 种不同的图像作为叠加添加。这意味着要定义 1000 多个模式。 :/

结果

最佳答案

其他一些解决方案走在正确的轨道上。您需要做的就是为您的 <pattern> 添加另一层用你想要的填充颜色。您可以将此颜色设为静态并在 SVG/HTML 或 CSS 中明确定义它。
如果您想要更大的灵活性，而不是添加 <rect>到 <pattern> ，您可以将每个多边形与一个重复的多边形分组，将第一个用于 background-color ，第二个是模式 fill .这允许所有这些属性( stroke 、 stroke-opacity 、 fill 等)独立。在此 #2 解决方案，我还添加了 preserveAspectRatio="xMidYMid slice"到 <pattern>确保背景图片始终居中，无需手动设置x和 y每次重新调整填充图像。
解决方案 #2 ，请向下滚动。
1. 为 <pattern> 添加静态填充颜色(下面#2)
