Hi guys ,

clear() function doesnt reset the object variables to default ,instead it just
resets them to empty strings, so i had to add myclear function to reset the variables to default otherwise after resize() clear() watermark() , watermarked image hasnt been created.


Code:
private function resize_image($filename)
{
  

  $info    =  pathinfo($filename);
  $rawname =  basename($filename,'.'.$info['extension']);
  
  $img_directory = $this->config->item('resim_klasoru');
  $fullpath      = $img_directory.$filename;

  $this->image_lib->myclear(); // clear()

  $config['image_library']  = 'gd2';
  $config['source_image']   = $fullpath;
  $config['create_thumb']   = FALSE;
  $config['maintain_ratio'] = TRUE;
  $config['width']       = 112;
  $config['height']       = 63;
  $config['dynamic_output'] = FALSE;
  $config['new_image']      = $img_directory.$rawname.'_new.'.$info['extension'];
  
  $this->image_lib->initialize($config);
  $this->image_lib->resize();

  echo $this->image_lib->display_errors();
  //unlink('./images/4_tmb.jpg');
  //$config['resim_klasoru'] = './images/'
  //
  //make thumbnail
  return $rawname.'_new.'.$info['extension'];
}

Code:
private function create_watermark($filename)
{

  $info    =  pathinfo($filename);
  $rawname =  basename($filename,'.'.$info['extension']);

  $img_directory = $this->config->item('resim_klasoru');
  $fullpath      = $img_directory.$filename;


  $this->image_lib->myclear(); //clear()
  


  $config['image_library']    = 'gd2';
  $config['source_image']     = $fullpath;
  $config['create_thumb']     = FALSE;
  $config['dynamic_output']   = FALSE;
  $config['wm_type']          = 'overlay';
  $config['wm_hor_offset']    = '-176';
  $config['wm_vrt_offset']    = '20';
  $config['wm_overlay_path']  ='./static_images/playbutton.png';
  $config['wm_padding']       = '0';
  $config['new_image']        = $img_directory.$rawname.'_new_watermark.'.$info['extension'];
  $config['width']         = 560;
  $config['height']         = 315;
  
  $this->image_lib->initialize($config);
  $this->image_lib->watermark();
  echo $this->image_lib->display_errors();

  return $rawname.'_new_watermark.'.$info['extension'];
}
