이 함수는 현재 문서화 되어있지 않습니다; 인수 목록만을 제공합니다.

Blurs an image. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, the radius should be larger than sigma. Use a radius of 0 and selects a suitable radius for you.

### 인수

`radius`

  The radius of the Gaussian, in pixels, not counting the center pixel.

`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 channeltype constants using bitwise operators. Defaults to `Imagick::CHANNEL_ALL`. Refer to this list of channel constants.

### 반환값
