images distorted on resize. What is causing this?

Hello,

When I upload an image, I create a thumb and then resize the orginal.
The thumb looks ok, but th eresized image looks out of focus.

Code:

function resize_image($filename)
    {
        if (isset($filename) AND strlen($filename)>0)
        {
            $config['image_library'] = 'gd2';
            $config['source_image'] = $_SERVER['DOCUMENT_ROOT'].'/img/category/'.$filename;
            //$config['new_image'] = $_SERVER['DOCUMENT_ROOT'].'/img/category/$filename';
            $config['maintain_ratio'] = TRUE;
            $config['create_thumb'] = FALSE;
            $config['width'] = 400;
            $config['height'] = 400;
            $config['quality'] = 100;

            $this->image_lib->initialize($config);
                        
            if(!$this->image_lib->resize()){
                die("Resize Failed." . $filename . '  ' . $this->image_lib->display_errors());
            }
            $this->image_lib->clear();
        }
    }

Just remove this following preference & test again...

Code:

$config['quality'] = 100;
