resize the same image 2 times

本文关键字：图像 2次调整 | 更新日期: 2023-09-26

我用php脚本上传图像，我希望能够改变图像的大小，如果图像太大，然后创建相同图像的拇指，现在我的图像是调整大小，但拇指没有创建出于某种原因…也没有错误。脚本如下:

        if($image_data['image_width'] > 1024 || $image_data['image_height'] > 768)
      {

    $config_resize = array(
            'source_image' => $image_data['full_path'],
            'new_image' => "./uploads/",
            'overwrite' => true,
            'maintain_ratio' => true,
            'width' => 1024,
            'height' => 768
            );
     $this->load->library('image_lib', $config_resize);
     if(! $this->image_lib->resize())
       {
         echo $this->image_lib->display_errors();
       }

    $config_thumb = array(
        'source_image' => $config_resize['source_image'],
        'new_image' => "./uploads/thumbs/",
        'maintain_ratio' => true,
        'width' => 150,
        'height' => 100
        );
    $this->load->library('image_lib', $config_thumb);
    if(! $this->image_lib->resize())
       {
         echo $this->image_lib->display_errors();
       }

      }

.....
.....  
    $config_thumb = array(
                'source_image' => $config_resize['source_image'],
                'new_image' => "./uploads/thumbs/",
                'maintain_ratio' => true,
                'width' => 150,
                'height' => 100
                );
$this->image_lib->initialize($config_thumb); // <--- !!!

和不要加载库两次
