Imagick::adaptiveBlurImage — Adds adaptive blur filter to image

### Description

Imagick::adaptiveBlurImage ( float `$radius` , float `$sigma` [, int `$channel` = Imagick::CHANNEL_DEFAULT ] ) : bool

Adds an adaptive blur filter to image. The intensity of an adaptive blur depends is dramatically decreased at edge of the image, whereas a standard blur is uniform across the image. This method is available if Imagick has been compiled against ImageMagick version 6.2.9 or newer.

### Parameters

`radius`

  The radius of the Gaussian, in pixels, not counting the center pixel. Provide a value of 0 and the radius will be chosen automagically.

`sigma`

  The standard deviation of the Gaussian, in pixels.

`channel`

  Provide any channel constant that is valid for your channel mode. To apply to more than one channel, combine channel constants using bitwise operators. Defaults to `Imagick::CHANNEL_DEFAULT`. Refer to this list of channel constants

### Return Values

Returns `TRUE` on success.

### Errors/Exceptions

Throws ImagickException on error.

### Examples

Example #1 Using Imagick::adaptiveBlurImage():

$image = new Imagick('test.jpg');
$image->adaptiveBlurImage(5,3);
echo $image;
?>`

The above example will output something similar to:
