說明

public Gmagick::embossimage(float $radius, float $sigma): Gmagick

Returns a grayscale image with a three-dimensional effect. 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 it will choose a suitable radius for you.

參數(shù)

radius

The radius of the effect.

sigma

The sigma of the effect.

返回值

The embossed Gmagick object.
