如何根据给定尺寸在Codeigniter中调整图像大小

Question

我已经添加了用于在codeigniter中调整图像大小的代码。

$configs['image_library'] = 'gd2';
$configs['source_image']    = './userpics/'.$new_name;
$configs['new_image'] = './userpics/userthumb/'.$new_name;
$configs['create_thumb'] = FALSE;
$configs['maintain_ratio'] = TRUE;

$configs['quality']  = '100';
$configs['width']   = 80;
$configs['height']  = 80;

但是图像以80 * 45或80 * 60的格式出现。 请让我知道任何解决方案，以便我可以显示适当的尺寸。

Answer 1

请参阅

https://ellislab.com/codeigniter/user-guide/libraries/image_lib.html

maintenance_ratio：TRUE / FALSE-指定在调整大小时是保持原始宽高比还是使用硬值。

Answer 2

$this->load->library('image_lib');
$config['image_library'] = 'gd2';
$config['source_image'] = "Mention your source location here";
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['height']   = "New Width";
$config['width'] = "New Height";
$config['new_image'] = "destination location";//you should have write permission here..
$this->image_lib->initialize($config);
$this->image_lib->resize();
