CI框架圖片裁剪

在圖片上傳成功後，調用圖片裁剪功能

 

1.加載CI類庫以及配置文件

$this->load->library('image_lib');

$config_thumb                   = $this->config->item("image_thumb");

配置文件

//縮略圖
$config['image_thumb']      = array(

    //gd2圖庫
    'image_library'         => 'gd2',
    //是否建立縮略圖
    'create_thumb'          => true,
    'maintain_ratio'        => true,
);

程序中調用

$config_thumb['source_image']      = $this->upload->data('full_path');
$config_thumb['new_image']         = $thumbpath."/".$imgname;


$big_thumb      = thumbUploadImg($config_thumb,array(300,300,"_300_300",));
$this->image_lib->initialize($big_thumb);
$this->image_lib->resize();

  自定義圖片裁剪封裝

        $config['width']             = 150;

    }
    $thumb                      = array_merge($thumb,$config);
    return $thumb;
