带有transloadit的旋转圆。是否可以使用水印或图像旋转？

const transloadit = require('transloadit');

const client = new transloadit.Client({
  authKey: 'YOUR_AUTH_KEY',
  authSecret: 'YOUR_AUTH_SECRET'
});

const assembly = client.createAssembly();

assembly.addFile('path/to/your/image.jpg');

assembly.addStep({
  name: 'rotate-and-watermark',
  robot: '/image/resize',
  use: {
    size: '800x600>',
    crop: 'limit',
    rotate: 'auto'
  }
});

assembly.addStep({
  name: 'add-watermark',
  robot: '/image/watermark',
  use: {
    watermark_url: 'https://example.com/watermark.png',
    position: 'bottom-right',
    opacity: 50
  }
});

assembly.start().then(result => {
  console.log(result);
}).catch(err => {
  console.error(err);
});
