library-image->watermark not work

[opencart-russia]

Hi. In image library function watermak not work.
\system\library\image.php

1. See line:
   private function create($image) {
   $mime = $this->info['mime'];
2. See line:
   imagecopy($this->image, $watermark, $watermark_pos_x, $watermark_pos_y, 0, 0, 120, 40);

[CoverUp]

Works for me, idk what r u pointing here, lines r correct.
BTW i use this instead for customization purposes
imagecopy($this->image, $watermark, $watermark_pos_x, $watermark_pos_y, 0, 0, $watermark_width, $watermark_height);//CoverUp
