openclaw - 💡(How to fix) Fix [Feature]: Auto-compress image attachments [1 comments, 1 participants]

Currently, images exceeding 5 MB are rejected with an error. Other AI assistants automatically compress images client-side before processing. It would improve UX if OpenClaw did the same. Greatly appreciate it. Example error: Error: attachment image: exceeds size limit (8885860 > 5000000 bytes)

Fix Plan

To implement automatic image compression, we can use a library like sharp in Node.js. Here are the steps:

• Install sharp using npm or yarn: npm install sharp or yarn add sharp
• Use the sharp library to compress images before processing
• Set a maximum size limit for compressed images (e.g., 5 MB)

Example code:

const sharp = require('sharp');

// Set maximum size limit (5 MB)
const maxSize = 5000000;

// Compress image function
async function compressImage(imageBuffer) {
  const metadata = await sharp(imageBuffer).metadata();
  if (metadata.size > maxSize) {
    // Compress image to fit within size limit
    const compressedImage = await sharp(imageBuffer)
      .resize({
        width: metadata.width / 2,
        height: metadata.height / 2,
      })
      .toFormat('jpeg', { quality: 80 })
      .toBuffer();
    return compressedImage;
  }
  return imageBuffer;
}

// Example usage:
const imageBuffer = // load image buffer from attachment
const compressedImage = await compressImage(imageBuffer);
// Process compressed image

Verification

To verify the fix, test uploading an image larger than 5 MB and check that it is compressed and processed successfully.

Extra Tips

• Adjust the compression quality and resizing factors to balance image quality and file size.
• Consider adding error handling for cases where image compression fails.
