Descrição

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.

Parâmetros

embossImage() will actually return a color image with a 3D effect. If you want a gray scale image, you can use imagefilter() from the regular GD functions.

<?php
header
("Content-type: image/jpeg");
$image = new Imagick("opossum.jpg");
$image->embossImage( 0, 1 );
echo
$image;
?>
