如何在PHP中实现模糊效果? [英] How to achieve a blur effect in PHP?

问题描述

我一直在寻找将高斯模糊应用于图像的PHP代码.

I've been looking for PHP code to apply a Gaussian blur to images.

我所做的就是这样:

<?php
$image = imagecreatefromjpeg('new.jpg'); 
imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);
imagejpeg($image, 'blur.jpeg');
imagedestroy($image);
?>

但是效果非常弱，如果我重复模糊效果，则需要花费很长时间进行处理，最终结果仍然不是那么好.

However the effect is very weak, and if I repeat the blur effect, it takes a very long time to process and the end result is still not that good.

我也使用Timthumb，我一直喜欢它的简单性，但是默认情况下它会裁剪图像，并且模糊效果非常弱.

I also used Timthumb , I always liked its simplicity, but it crops the image by default and its blurring effect is very weak.
