php使用高斯算法实现图片的模糊处理功能示例

本文实例讲述了php使用高斯算法实现图片的模糊处理功能。分享给大家供大家参考，具体如下：

				?

									<?php

									class image_blur{

									   function gaussian_blur($srcimg,$savepath=null,$savename=null,$blurfactor=3){

									    $gdimageresource=$this->image_create_from_ext($srcimg);

									    $srcimgobj=$this->blur($gdimageresource,$blurfactor);

									    $temp = pathinfo($srcimg);

									    $name = $temp['basename'];

									    $path = $temp['dirname'];

									    $exte = $temp['extension'];

									    $savename = $savename ? $savename : $name;

									    $savepath = $savepath ? $savepath : $path;

									    $savefile = $savepath .'/'. $savename;

									    $srcinfo = @getimagesize($srcimg);

									    switch ($srcinfo[2]) {

									      case1: imagegif($srcimgobj, $savefile); break;

									      case2: imagejpeg($srcimgobj, $savefile); break;

									      case3: imagepng($srcimgobj, $savefile); break;

									      default: return'保存失败'; //保存失败

									    }

									    return $savefile;

									    imagedestroy($srcimgobj);

									  }

									}

									$image_blur = new image_blur();

									//blurfactor的值代表模糊程度，savepath为空时候直接覆盖，savename为空直接用原名

									$image_blur->gaussian_blur($srcimg="./5.jpg",$savepath=null,$savename=null,$blurfactor=5);

									?>
