尝试支持动画时SVG文字颠倒

我无法使文本方向正确。我按照SVG TextPath Text shows upside-down上的建议进行了尝试,但是它使动画从相反的一侧开始。我需要动画从初始节点开始。

我正在使用stroke-dashoffset和stroke-dasharray制作动画。 在下面的代码中,我显示了可能的各种线条,并且方向用箭头显示。

<!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>

我的解决方案是使用文本的反向路径。我已将反向路径放入<defs>中。我使用的是金色笔触,而我使用的是反向路径。我希望这就是您所需要的。

@keyframes dash {
  to {
    stroke-dashoffset: 0;
  }
}
path {
  animation: dash 2s linear forwards;
  stroke-dasharray: 1500;
  stroke-dashoffset: 1500;
}
