Headers - Text over image!

[John Kesterton]

Good Afternoon,

I am trying to render a header image in dompdf which is working fine.
I would now like to add some text over the image however it always
renders underneath!?!

My code is as follows.....Any suggestions would be greatly apreciated.

<script type="text/php">
if( isset($pdf) ) {
//header and footer
$obj = $pdf->open_object();

//header text
$font = Font_Metrics::get_font("Helvetica");
$fontsize = 10;
$fontcolor = array(0.4,0.4,0.4);

$pdf->page_text($pdf->get_width()-100, $pdf->get_height()-40,
"Page {PAGE_NUM} of {PAGE_COUNT}", $font, $fontsize, $fontcolor);

//header image
$image = './images/reportheader.png';
$points = 3142 * 72 / 96;
$points2 = 229 * 72 / 96;
$pdf->page_text(60, 46, "Title Text", $font, $fontsize, $fontcolor);
$pdf->image($image, 'png', 44, 36,754,54);
$pdf->close_object();
$pdf->add_object($obj, 'all');
}
</script>

The core of your problem is that creating an object, adding text/images, and then adding that object to a PDF works separately from the page_text() method. You should rewrite your code as follows to make that clear:

<script type="text/php">
if( isset($pdf) ) {

  // global page text

  $font = Font_Metrics::get_font("Helvetica");

  $fontsize = 10;
  $fontcolor = array(0.4,0.4,0.4);

  $pdf->page_text($pdf->get_width()-100, $pdf->get_height()-40, "Page {PAGE_NUM} of {PAGE_COUNT}", $font, $fontsize, $fontcolor);

  $pdf->page_text(60, 46, "Title Text", $font, $fontsize, $fontcolor);

  //header image
  $obj = $pdf->open_object();

  $image = './images/reportheader.png';
  $points = 3142 * 72 / 96;
  $points2 = 229 * 72 / 96;

  $pdf->image($image, 'png', 44, 36,754,54);
  $pdf->close_object();
  $pdf->add_object($obj, 'all');
}
</script>

I'd have to go back and review the source to confirm, but the order which page_text() content and header/footer objects are added will affect which appears on top of the other. page_text() may very well be rendered first and so be layered underneath the header/footer objects.

Unfortunately, the placeholder text can not be used in $pdf->text() which is what you would use to add text to a header/footer object.

In the 0.6.0 release, if you don't need the total number of pages you can rewrite your header/footer entirely in HTML. (There is a way to output the current page number.)
