What does this adaptive_resize method do?
It crops an images. The difference between this extension and the native crop is it first re-sizes the image to your specification and then crops the re-sized image giving you a fixed image size.
How do I use it?
You use it by calling it like you would a native method. Only difference is you must pass two new config values.
$config['ar_width'] = 200;
$config['ar_height'] = 100;
$config['width'] = 200;
$config['height'] = 100;
It is recomended that the ar_width/ar_height are the same as width/height.
Can I see a usage example?
$this->load->library('image_lib');
$config['image_library'] = 'gd2';
$config['maintain_ratio'] = TRUE;
$config['width'] = 200;
$config['height'] = 100;
$config['ar_width'] = 200; //new config option
$config['ar_height'] = 100; //new config option
$config['source_image'] = '/path/to/image/imagename.jpg';
$config['new_image'] = '/path/to/saved/image/imagename.jpg';
$this->ci->image_lib->initialize($config);
$this->ci->image_lib->adaptive_resize(); //new method
