说明

bool Imagick::adaptiveBlurImage ( float $radius , float $sigma [, int $channel ] )

Warning

本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

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.

参数

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.

返回值

Returns TRUE on success.

错误／异常

Throws ImagickException on error.

范例

Example#1 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;

?>
