Imagick::adaptiveBlurImage

(PECL imagick 2.0.0)

Adds adaptive blur filter to image

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

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

Returns:

Returns TRUE on success.

Exception:

Throws ImagickException on error.

Examples:

Using Imagick::adaptiveBlurImage() :

$image = new Imagick('test.jpg');

$image->adaptiveBlurImage(5,3);
