# ImageBlur

Blurs an image by a specified radius. This BIF allows you to apply a blur effect to an image in BoxLang, controlling the strength of the blur.

## Syntax

```
ImageBlur(name [, blurRadius])
```

## Arguments

| Name       | Type    | Required | Default | Description                                                                 |
| ---------- | ------- | -------- | ------- | --------------------------------------------------------------------------- |
| name       | any     | Yes      |         | The image or the name of a variable referencing an image to operate on.     |
| blurRadius | numeric | No       | 3       | The amount to blur the image. Higher values produce a stronger blur effect. |

## Returns

* **BoxImage**: The modified BoxImage instance with the blur applied.

## Description

`ImageBlur` applies a blur effect to the specified image. The blur radius controls the strength of the blur; higher values result in a more pronounced blur. The image can be passed directly or referenced by variable name.

## Example

```boxlang
// Blur an image with the default radius (3)
img = ImageBlur(myImage);

// Blur an image with a radius of 10
img = ImageBlur(myImage, 10);
```

## See Also

* ImageSharpen
* ImageAddBorder

## Notes

* The default blur radius is 3 if not specified.
* The image can be passed as a BoxImage object or as a variable name referencing an image.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://boxlang.ortusbooks.com/boxlang-framework/modularity/image-manipulation/reference/built-in-functions/imageblur.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
