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>
