# Gmagick::motionblurimage

(PECL gmagick >= Unknown)

Gmagick::motionblurimage — Simulates motion blur

### 说明

public Gmagick::motionblurimage(float `$radius`, float `$sigma`, float `$angle`): Gmagick

Simulates motion blur. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. Use a radius of 0 and Gmagick::motionblurimage() selects a suitable radius for you. Angle gives the angle of the blurring motion.

### 参数

`radius`
  The radius of the Gaussian, in pixels, not counting the center pixel.
`sigma`
  The standard deviation of the Gaussian, in pixels.
`angle`
  Apply the effect along this angle.

### 返回值

The Gmagick object.

### 错误／异常

错误时抛出 GmagickException。
