javascript - 如何绘制动画效果填充SVG？

Question

我正在尝试为 SVG Logo 制作动画，就像绘制没有描边的填充路径一样。我的 Logo 看起来像那样。

是否可以创建填充图而不是笔划？我看到了很多解决方案，但都是笔画使用的。我还找到了This solution与我的问题非常相似。但是我的 SVG 路径有点复杂，无法创建具有他们创建的类似笔划的假路径。我想让它从无到有，并用填充绘制动画效果。

我的完整 SVG 代码在这里

Answer 1

Because your SVG file is not in the same shape as my logo. can you please tell me how can I modify the path to achieve the exact same shape. I don't have much knowledge about the illustrator by the way.

不幸的是我没有使用插画家。在 Inkscape 中绘制的路径

打开上一个答案中的文件以在Inkscape 中编辑路径

1. 在工具栏上的矢量编辑器中选择Edit contour nodes F2(红色箭头-1)

2. 通过拖动节点来编辑曲线的形状并更改节点控制杆的长度和位置(箭头红色-2)

3. 矢量编辑器节省了大量开销信息。要删除它，您需要使用 SVG Editor 优化保存的文件。

4. 用优化文件中的新路径替换旧的路径
