Imagick::adaptiveBlurImage — Adds adaptive blur filter to image
Description
bool Imagick::adaptiveBlurImage ( float $radius , float $sigma [, int $channel = Imagick::CHANNEL_DEFAULT ] )

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

Errors/Exceptions
Throws ImagickException on error.
