PHP Manual: Returns a grayscale image with a three-dimensional effect

Description

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

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.

Parameters

radius: The radius of the effect.
sigma: The sigma of the effect.

Return Values

The embossed Gmagick object.
