有没有办法使用Google Apps脚本渲染图像？

function renderImage() {
  var doc = DocumentApp.getActiveDocument();
  var body = doc.getBody();
  
  // 创建一个Canvas元素
  var canvas = document.createElement('canvas');
  canvas.width = 400;
  canvas.height = 300;
  
  // 获取Canvas的上下文
  var context = canvas.getContext('2d');
  
  // 在Canvas上绘制图像
  var image = new Image();
  image.src = 'https://example.com/image.jpg';
  image.onload = function() {
    context.drawImage(image, 0, 0);
    
    // 将Canvas转换为图像URL
    var imageUrl = canvas.toDataURL();
    
    // 在Google Docs中插入图像
    var blob = Utilities.newBlob(imageUrl, 'image/png');
    body.appendImage(blob);
  };
}
