Imagick::adaptiveBlurImage
Adds adaptive blur filter to image
()
bool Imagick::adaptiveBlurImage ( float radius, float sigma [, int channel] )
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.
Adds an adaptive blur filter to image. The intensity of an adaptive blur depends is dramatically decreased at edge of the image, whereas a standard blur is uniform across the image.
Parameters
- radius
The radius of the Gaussian, in pixels, not counting the center pixel. Provide a value of 0 and the radius will be chosen automagically.
- sigma
The standard deviation of the Gaussian, in pixels.
- channel
Provide any channel constant that is valid for your channel mode. To apply to more than one channel, combine channeltype constants using bitwise operators. Defaults to Imagick::CHANNEL_ALL. Refer to this list of channel constants.
Examples
Example 1030. Using Imagick::adaptiveBlurImage():
Adaptively blur an image, then display to the browser.
<?php
header('Content-type: image/jpeg');
$image = new Imagick('test.jpg');
$image->adaptiveBlurImage(5,3);
echo $image;
?>
