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：
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 ($srcinfo) {
case1: imagegif($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);
?>
