writeImage（）时的页面错误

Question

I have script to resize my photo with Imagick and then save. Here is code to make thumbnail with thiumbnailImage();

<?php
  header('Content-type: image/jpeg');
  $image = new Imagick('test.jpg');
  $image->thumbnailImage(600, 0);
  echo $image;
?>

Exmaple -> Resize example just thumbnailImage();.

This works. But when i want to save it with writeImage();.

<?php
  header('Content-type: image/jpeg');
  $image = new Imagick('test.jpg');
  $image->readImage('test.jpg');
  $image->thumbnailImage(600, 0);
  $image->writeImage('test_resized.jpg');
?>

It display server error. Example -> Example resize with writeImage();

Answer 1

It seems you probably don't have write permission to that directory.. Set permission(CHMOD) to 777.
