PHP - 模糊图像有更好/更聪明的方法吗？ [重复]

Question

This question already has an answer here:

• PHP/GD : Better Gaussian blur 5 answers

I use gaussian blur. 1 line of

imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);

doesn't give the desired blur intensity. So I need to use it like 30 times. This is an unprofessional way, it increases the page load time a lot when there are many images on the page. So is there any better/smarter way for image blur ?

  $image = imagecreatefromjpeg("caski_m.jpg");
  imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);
  header("content-type: image/jpeg");
  imagepng($image);
  imagedestroy($image);

If you are searching more concise and elegant solution then:

1. install ImageMagick extension for php
2. use php exec command to invoke ImageMagick convert operator:

Schema: exec("convert <your_image_name> -blur <blur_level> <your_blured_image_name> ");
You can adjust blur level flexibly.
Example: exec("convert '$image' -blur 0x8 'blur_' . $image");
But don't forget to specify accesible image path.
