Imagick::embossImage

(PECL imagick 2, PECL imagick 3)

Imagick::embossImageReturns a grayscale image with a three-dimensional effect

Description

public Imagick::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.

Parameters

radius

The radius of the effect

sigma

The sigma of the effect

Return Values

Returns true on success.

Errors/Exceptions

Throws ImagickException on error.

Examples

echo
$imagick->getImageBlob();
}

?>

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;
?>
