Две функции duplicate и resize

[novakabg]

Проблема ми е следният , след като ползвам функция resize не прави дублиране на файла а редактира същият файл.
Взех $suffix = empty($args['suffix']) ? 'copy' : $args['suffix'];
пробвах да го вкарам в resize но не се получи

protected function duplicate($args) {
		$targets = is_array($args['targets']) ? $args['targets'] : array();
		$result  = array('added' => array());
		$suffix  = empty($args['suffix']) ? 'copy' : $args['suffix'];
		
		foreach ($targets as $target) {
			if (($volume = $this->volume($target)) == false
			|| ($src = $volume->file($target)) == false) {
				$result['warning'] = $this->error(self::ERROR_COPY, '#'.$target, self::ERROR_FILE_NOT_FOUND);
				break;
			}
			
			if (($file = $volume->duplicate($target, $suffix)) == false) {
				$result['warning'] = $this->error($volume->error());
				break;
			}
			
			$result['added'][] = $file;
		}
		
		return $result;
	}

	protected function resize($args) {
		$target = $args['target'];
		$width  = $args['width'];
		$suffix  = empty($args['suffix']) ? 'copy' : $args['suffix'];
		
		$height = $args['height'];
		$x      = (int)$args['x'];
		$y      = (int)$args['y'];
		$mode   = $args['mode'];
		$bg     = null;
		$degree = (int)$args['degree'];
		$quality= (int)$args['quality'];
		
		if (($volume = $this->volume($target)) == false
		|| ($file = $volume->file($target)) == false) {
			return array('error' => $this->error(self::ERROR_RESIZE, '#'.$target, self::ERROR_FILE_NOT_FOUND));
		}

		return ($file = $volume->resize($target, $width, $height, $x, $y, $mode, $bg, $degree, $quality, $suffix))
			? array('changed' => array($file))
			: array('error' => $this->error(self::ERROR_RESIZE, $volume->path($target), $volume->error()));
	}
