CI_Image_lib::crop()

crop()

The cropping method works nearly identically to the resizing function except it requires that you set preferences for the X and Y axis (in pixels) specifying where to crop, like this:

$config['x_axis'] = 100;
$config['y_axis'] = 40;

All preferences listed in the Preferences table are available for this method except these: rotation_angle, create_thumb and new_image.

Here’s an example showing how you might crop an image:

$config['image_library'] = 'imagemagick';
$config['library_path'] = '/usr/X11R6/bin/';
$config['source_image'] = '/path/to/image/mypic.jpg';
$config['x_axis'] = 100;
$config['y_axis'] = 60;

$this->image_lib->initialize($config);

if ( ! $this->image_lib->crop())
{
        echo $this->image_lib->display_errors();
}
