Imagick::adaptiveBlurImage — Adds adaptive blur filter to image

Description

public 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.
