How to display dynamic button in codeigniter using Gd library?

Question

I created form with dynamic color,font,size of button . when i submit the form, button image displaying in full page,i need to display in first page itself.

my controller code :

public function creatorbuton(){
    $button_size = $this->input->POST('button_size');
    $font_style = $this->input->POST('font_style');
    $color_schme = $this->input->POST('color_schme');
    $textdisplay = $this->input->POST('textdisplay');
    header('content-type: image/png');

    //Create our basic image stream 
    //125px width, 125px height
    $image = imagecreate(120, 60);

    //Set the background color
    $blue = imagecolorallocate($image, 150, 50, 105);

    //Set up another color just to show how the first color declared is used as the background color when we use imagecreate() 
    //Notice how blue is applied to the background, *not* red.
    $red = imagecolorallocate($image, 150, 200, 10);

    //$font = myurl.'fonts/arial.ttf';
    //$text="Hello";
    //imagettftext($image, 20, 0, 11, 21, $red, $font, $text);
    //save the image as a png and output 
    $result_array['final_image'] = imagepng($image);

    //Clear up memory used
    imagedestroy($image);
    $this->load->view('buttonconfig/buttoncreator',$result_array);

How to dispaly the button in buttoncreator view page. When i used uncomment this line

imagettftext($image, 20, 0, 11, 21, $red, $font, $text);

I got this line " The image MY URL cannot be displayed baecause it contains errors" .

    imagestring($image,18,0,0,$textdisplay,$red); 
    imagepng($image);
    imagedestroy($image);
