    I'll trying to place an image in the header. I have:

    $header = '';
    $paramsImg = array(
    'name' => $_SERVER['DOCUMENT_ROOT'].'/img/header.png',
    'scaling' => 100,
    'spacingTop' => 100,
    'spacingBottom' => 0,
    'spacingLeft' => 100,
    'spacingRight' => 0,
    'textWrap' => 1,
    'js' => 'center',
    'border' => 1,
    'borderDiscontinuous' => 1
    );


    $docx->addHeader($header, $paramsImg);

    I get the image importing fine, however the image has a width of 0" and height of (basically infinite). I've tried the sixeX, sixeY with other combinations, with no change in results. Am I missing a param to make it work? Thanks.

    The code seems to be ok, so try with relative path to image.

    I think I found the root cause.

    classes/CreateImage::
    private function getDpiPng($filename)
    {
    $a = fopen($filename, 'r');
    $string = fread($a, 1000);
    $aux = strpos($string, 'pHYs'); // <-- $aux = 0, pHYs is not in the file
    $data = bin2hex(substr($string, $aux + strlen('pHYs'), 16));
    fclose($a);
    $x = substr($data, 0, 8);
    $y = substr($data, 8, 8);
    return array(hexdec($x), hexdec($y));
    }
