我找到了有关渲染 SVG 的主题在 HTML5 画布上绘制 SVG 文件。有没有办法在特定时间绘制 SVG 动画文件?我的意思是,如何更改代码
var img = new Image();
img.onload = function() {
ctx.drawImage(img, 0, 0); // define time at here: time="1.3sec"
}
img.src = "myfile.svg";
这样img
在特定时间包含svg?文件 myfile.svg 包含以下内容:
<svg
xmlns="http://www.w3.org/2000/svg"
viewBox="0 0 200 200"
id="svg2">
<g transform="translate(100, 100)">

人们通常建议使用canvg,但据我了解它不支持路径动画,所以我的示例不适用于它。
