(PECL imagick 2.0.0)
Returns a grayscale image with a three-dimensional effect
bool Imagick::embossImage ( float $radius, float $sigma )
Returns a grayscale image with a three-dimensional effect. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. Use a radius of 0 and it will choose a suitable radius for you.
Parameters:
radius
The radius of the effect
sigma
The sigma of the effect
Returns:
Returns TRUE
on success.
Exception:
Throws ImagickException on error.
Examples:
Imagick::embossImage()
<?php function embossImage($imagePath, $radius, $sigma) { $imagick = new \Imagick(realpath($imagePath)); $imagick->embossImage($radius, $sigma); header("Content-Type: image/jpg"); echo $imagick->getImageBlob(); } ?>
