I solved my problem by:
in html2pdf.class.php file at line 5602. by adding the server Document Root to image source.
protected function _tag_open_IMG($param)
{
$src = str_replace('&', '&', $param['src']);
$documentRoot = $_SERVER['DOCUMENT_ROOT']; // get server document root
$src = $documentRoot. '/' . $src; //aapend server document root to the image soure
$this->parsingCss->save();
$this->parsingCss->value['width'] = 0;
$this->parsingCss->value['height'] = 0;
$this->parsingCss->value['border'] = array('type' => 'none', 'width' => 0, 'color' => array(0, 0, 0));
$this->parsingCss->value['background'] = array('color' => null, 'image' => null, 'position' => null, 'repeat' => null);
$this->parsingCss->analyse('img', $param);
$this->parsingCss->setPosition();
$this->parsingCss->fontSet();
$res = $this->_drawImage($src, isset($param['sub_li']));
if (!$res) return $res;
$this->parsingCss->load();
$this->parsingCss->fontSet();
$this->_maxE++;
return true;
}

In this case html2pdf.class.php just take the image path instead of url, actually you dont need to change the library code, just need...
<img src="<?=Yii::getPathOfAlias('webroot').'/images/big-logo.png'?>">
for background image...
<div style="background-image: url(<?=Yii::getPathOfAlias('webroot').'/images/big-logo.png'?>)">
...
</div>
