I try many way and i still can't get it right. If you've done it before, maybe you can share some experience ?
I got the image uploaded. I got the image resized. The crop is the problem here.
Code:
<?php
class Img extends Controller {
function index()
{
$this->load->view('img_view.php');
}
function process()
{
$config['upload_path'] = FCPATH.'img/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['file_name'] = time().'_tictac';
$config['max_size'] = '2048';
$this->load->library('upload', $config);
$this->upload->do_upload();
$this->load->library('image_lib');
$info = $this->upload->data();
$this->_createThumbnail($info['file_name']);
$this->_cropThumbnail($info['raw_name'].'_thumb'.$info['file_ext']);
function _createThumbnail($fileName)
{
$config['image_library'] = 'gd2';
$config['source_image'] = FCPATH.'img/' . $fileName;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['quality'] = '100%';
$config['width'] = 200;
$config['height'] = 200;
$this->image_lib->initialize($config);
$this->image_lib->resize();
}
function _cropThumbnail($thumbName)
{
$config['image_library'] = 'imagemagick';
$config['quality'] = '100%';
$config['x_axis'] = 88 ;
$config['y_axis'] = 66 ;
$this->image_lib->initialize($config);
$this->image_lib->crop();
}

It's probably too late and you already know the answer, but just in case:
When you use ImageMagick you must specify $config['library_path'].
Good luck!

Here's some code from my gallery app, QuickSnaps, that handles cropping:
Code:
function _crop_image($p, $x_off, $y_off)
{
$config['image_library'] = 'imagemagick';
$config['library_path'] = '/usr/bin/convert';
$config['source_image'] = './'.$p->photo.$p->photo_type;
$config['maintain_ratio'] = FALSE;
$config['x_axis'] = ceil ( $this->input->post('x') * $x_off );
$config['y_axis'] = ceil ( $this->input->post('y') * $y_off );
$config['width'] = $this->input->post('w') * $x_off;
$config['height'] = $this->input->post('h') * $y_off;
$this->image_lib->initialize($config);
if ( ! $this->image_lib->crop())
{
echo $this->image_lib->display_errors();
}
$this->image_lib->clear();

you have to clear your image lib. stated in the last example $this->image_lib->clear();
