Overview
The "Blur Image" operation of the Mallabe Images node allows users to apply a blur effect to an image accessible via a public URL. This operation sends the image URL and a blur intensity value to an external image processing service, which returns a blurred version of the image. Users can choose either to download the processed image directly into the workflow or receive a link to the blurred image.
This node is beneficial in scenarios where you want to obscure sensitive information in images automatically, create artistic effects, or prepare images for privacy-compliant sharing. For example, blurring faces in photos before posting on social media or blurring backgrounds in product images for marketing materials.
Properties
| Name | Meaning |
|---|---|
| Image URL | Public URL of the image file to blur |
| Blur Value | A numeric value from 0.3 to 1000 indicating the intensity of the blur; higher values produce stronger blur |
| Download Image? | Boolean option to decide whether to download the blurred image binary data or just return a link |
| Put Output File In Field | When downloading, specifies the name of the output field where the binary image data will be stored |
| Webhook URL (Advanced) | Optional URL to send a webhook with the data of the operation |
Output
- If Download Image? is set to
false, the node outputs JSON containing at least aurlfield with a link to the blurred image. - If Download Image? is set to
true, the node outputs JSON along with a binary data field containing the actual blurred image file. The binary data is placed under the user-specified output field name. - The JSON output structure includes metadata about the processed image returned by the external API.
Dependencies
- Requires an active connection to the Mallabe Images API service.
- Needs an API key credential configured in n8n for authentication with the Mallabe Images API.
- Internet access is required to fetch the original image from the provided URL and to send requests to the external API.
- Optionally, if using the webhook URL property, an accessible endpoint must be provided to receive webhook callbacks.
Troubleshooting
- Invalid Image URL: If the provided URL is not publicly accessible or does not point to a valid image, the API may return an error or fail to process the image.
- Blur Value Out of Range: Values below 0.3 or above 1000 might cause errors or unexpected results. Ensure the blur value is within the specified range.
- Download Failures: If downloading the image fails, check that the returned URL is accessible and that the node has permission to fetch external resources.
- API Authentication Errors: Verify that the API key credential is correctly configured and has sufficient permissions.
- Webhook URL Issues: If using the webhook URL, ensure the endpoint is reachable and properly handles incoming requests to avoid timeouts or failures.
