    y: 100,
    r: 50,
    color: 'red'
  }]
}).toFile('output.jpg');
```

**19. Resize Image with Minimum Steps:**

const pipeline = require('util').pipeline;
pipeline(
  sharp('input.jpg').resize(300, 200),
  fs.createWriteStream('output.jpg')
);
```

**25. Batch Process Images:**

```js
const glob = require('glob');
const fsPromises = require('fs').promises;
const path = require('path');
const sharp = require('sharp');

async function batchProcessImages() {
  const files = await fsPromises.readdir('input');
  for (const file of files) {
    try {
      const outputPath = path.join('output', file);
      await sharp(`input/${file}`).resize(300, 200).toFile(outputPath);
      console.log(`Processed ${file}`);
    } catch {
      console.log(`Error processing ${file}`);
    }
  }
}
