    Gmagick::motionblurimage — Simulates motion blur

    說明

    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.

    參數(shù)

    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.
