Imagick::embossImage — Returns a grayscale image with a three-dimensional effect
Description
bool Imagick::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.
