    Beschreibung

    publicImagick::embossImage(float$radius, float$sigma): bool

    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.

    Parameter-Liste

    radius

    The radius of the effect

    sigma

    The sigma of the effect

    Rückgabewerte
