篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在尝试支持动画时，SVG文本颠倒了相关的知识，希望对你有一定的参考价值。
我无法正确显示文字方向。我按照SVG TextPath Text shows upside-down的建议尝试，但它使动画从对面开始。我需要从初始节点开始动画。
我正在使用stroke-dashoffset和stroke-dasharray进行动画制作。在下面的代码中，我展示了各种可能的线条，方向用箭头表示。
<!DOCTYPE html>
<html>
<head>
<style>
@keyframes dash {
to { stroke-dashoffset: 0; }
}
path {
animation: dash 2s linear forwards;
stroke-dasharray: 1500;
stroke-dashoffset: 1500;
}
</style>
</head>
<body>
<svg width="1580" height="390" viewbox="0 0 1580 790" preserveaspectratio="none">

我的解决方案是使用反向路径的文本。我在<defs>推出了相反的路径。我正在使用一个黄金笔划，我正在使用反向路径。我希望这就是你所需要的。
