Bug with image_lib and solution

[eluser]Pierre Sandora[/eluser]
Hello,

Some people had problem with image_lib and your dynamic_output, me too. What happening is that there are contents in buffer when you call

Code:

$this->image_lib->resize();

on function controller. Resize method send headers, but before him CI write in buffer, so image dont display. I try put ob_start and ob_end_flush on index.php, but dont solved.
What solved this problem was put a

Code:

while (@ob_end_clean());

before

Code:

$this->image_lib->resize();

into my controller function.

Code:

function view_image($profile_attribute_id) { //controller function
        settype($profile_attribute_id,'integer');
        if (!empty($profile_attribute_id)) {
            $value = new value_model();
            $value->profile_attribute_id = $profile_attribute_id;
            $value->load_content();
            while (@ob_end_clean());
            $config2['image_library'] = 'gd2';
            $config2['source_image'] = '../uploads/images/profile/'.$value->file_name;
            $config2['maintain_ratio'] = TRUE;
            $config2['dynamic_output'] = TRUE;
            $config['quality'] =     100;
            $config2['width'] = 75;
            $config2['height'] = 50;
            $this->load->library('image_lib', $config2);
            $this->image_lib->resize();
        }
    }

I call http://localhost/code/user/view_image/80 and display an image on browser.
