当我通过在d属性中保留内容来组合所有这些路径时，我得到了图像，但它只有一种填充颜色。

如何将这些svg路径转换为一个单独的计算路径，并保留黑白填充的原始图像。我需要一个单一的路径来把它作为一个对象放在一个自定义的js文件中，在那里我们注册图标并将它们与font-awsome icon- vue组件一起使用。通过使用各种格式的图标来注册图标

var faSnd = {
    prefix: 'fac',
    iconName: 'snd-coin',

Answer 1

您可以在Inkscape (开源svg编辑器)中使用Path组合svg路径。这可能会强制所有路径具有相同的颜色。

如果您已将图像(如位图)导入到Inkscape中，请先使用路径创建路径，然后才能合并。

Answer 2

这里是只有一条路径的SVG。这就是我所做的:我去掉了白色的路径，加入了2条黑色的路径。看到我代码中的漏洞了吗？是第一条路径结束的地方，最后一条路径开始的地方。

现在唯一的问题是，以前的白色路径现在是一个透明区域。如果你给你的SVG一个背景，你会通过间隙看到它。
