[英]Resize and rotate image - Codeigniter
我正在嘗試調整圖像大小並旋轉圖像。
目前,它只是調整圖像的大小,而不旋轉它。
這是代碼,希望有人有解決方案:-)
$config['image_library'] = 'gd2';
$config['source_image'] = $data['full_path'];
$config['new_image'] = $data['file_path'].'thumbs/'.$data['file_name'];
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 235;
$config['height'] = 235;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$this->image_lib->clear();
$config['create_thumb'] = FALSE; //No thumbnail
$config['source_image'] = $data['file_path'].'thumbs/'.$data['file_name']; //full path for the source image
$config['rotation_angle'] = '180';//
$this->load->library('image_lib',$config);
//Rotate the image
$this->image_lib->rotate();
后
$this->image_lib->clear();
加:
$config = array()
重新初始化您的配置數組。
清除配置后,不要重新加載庫,請重新初始化它:
$this->image_lib->clear();
$config=array();
$config['image_library'] = 'gd2';
$config['source_image'] = $data['file_path'].'thumbs/'.$data['file_name'];
$config['rotation_angle'] = '180';
$this->image_lib->initialize($config); // reinitialize it instead of reloading
$this->image_lib->rotate();
這是最終對我有用的唯一解決方案。 僅重新初始化$ config在CodeIgniter 2.2.0中不起作用。
確保在重新發送$ config之前重新創建它。
否則,您可能最終會發送不想發送的值。
此刻rotate()得到一個$ config,如下所示:
$config['image_library'] = 'gd2';
$config['new_image'] = $data['file_path'].'thumbs/'.$data['file_name'];
$config['maintain_ratio'] = TRUE;
$config['width'] = 235;
$config['height'] = 235;
$config['create_thumb'] = FALSE; //No thumbnail
$config['source_image'] = $data['file_path'].'thumbs/'.$data['file_name']; //full path for the source image
$config['rotation_angle'] = '180'; //
