检查 ImageMagick 是否安装(可以使用 phpinfo).如果是，您可以使用以下代码覆盖到 PNG.

Check if ImageMagick is installed (you can find out using phpinfo). If it is, you can use the following code to cover to a PNG.

$image = new Imagick();
$image->readImageBlob(file_get_contents('image.svg'));
$image->setImageFormat("png24");
$image->resizeImage(1024, 768, imagick::FILTER_LANCZOS, 1); 
$image->writeImage('image.png');
