PHP using a Gaussian algorithm to implement the image of the fuzzy processing function Example _php tips

This article illustrates the use of a Gaussian algorithm in PHP to implement the fuzzy processing function of the image. Share to everyone for your reference, specific as follows:

<?php class image_blur{function Gaussian_blur ($srcImg, $savepath =null, $savename =null, $blurFactor =3) {$gdImageRe
    Source= $this->image_create_from_ext ($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, $savefile); Case2:imagejpeg ($SRCIMGOBJ, $savefile);
      Break Case3:imagepng ($SRCIMGOBJ, $savefile);
      Break Default:return ' save failed ';
    Save failed} return $savefile;
  Imagedestroy ($SRCIMGOBJ);
}} $image _blur = new Image_blur (); The Blurfactor value represents the ambiguity degree, Savepath is the empty time direct cover, the savename is the empty direct use formerly known as $image _blur->gaussian_blur ($srcImg = "./5.jpg", $savepath =null, $savename =null, $blurFactor =5);?>

 

This method Baidu to, there is an interview I let me do, Baidu a pile of information to achieve.

The value of the Blurfactor represents the degree of ambiguity

Effect Display:

Original:

Blur degree 2

Blur degree 3

Blur degree 4

Blur degree 5

Blur degree 6

Blur degree 7
