1001fx - NoCode functionsInstall

Overview

The "Scale an Image" operation in the images resource of this n8n node allows you to resize an image by a specified scaling factor. This is useful for automating image processing tasks such as preparing images for web use, generating thumbnails, or batch-resizing images before uploading them to other services.

Practical examples:

• Automatically resizing user-uploaded profile pictures to fit a standard size.
• Scaling down large images before sending them via email or storing them in a database.
• Creating smaller preview versions of product images for an e-commerce site.

Properties

Output

• The output will contain a binary field with the scaled image data.
• The name of the binary property containing the output image is determined by the Binary Property input (default: data).
• The binary data includes:
  • The scaled image file.
  • Metadata such as filename and content type, preserved from the API response.

Example output structure:

{
  "json": { /* original item JSON */ },
  "binary": {
    "data": {
      "data": "<Buffer ...>", // The scaled image binary data
      "fileName": "scaled-image.jpg",
      "mimeType": "image/jpeg"
    }
  },
  "pairedItem": { "item": 0 }
}

Dependencies

• External Service: Requires access to the 1001fx API.
• API Key: You must configure the 1001fxApi credential in n8n.
• Environment: No additional environment variables are required beyond the API key setup.

Troubleshooting

Common issues:

• Invalid scaling factor: If the factor is not within the allowed range (0.000001 to 10), the API may return an error.
• Missing or invalid image file: If the image file is not provided or is corrupted, the operation will fail.
• Incorrect binary property name: If the specified binary property name does not match the expected input/output, the result may not be accessible in subsequent nodes.

Error messages:

• "error": "Request failed with status code 400" – Check that all required properties are set correctly and the image file is valid.
• "error": "Invalid API key" – Ensure your 1001fx API credentials are configured properly in n8n.
• "error": "Cannot read property 'split' of undefined" – This may occur if the API response headers are missing; check the API service status.
