Question

I’m using PDFlib library PHP to write PDF.

Can I put an image as a background for a whole page? If so, how can I do it?

Answer 1

In general you should do something like this:

$image = $p->load_image("auto", $imagefile, "");
if ($image == 0) {
    die("Error: " .  $p->get_errmsg());
}
$p->begin_page_ext(0, 0, "width=595 height=842");
$p->fit_image($image 0, 0, "boxsize { 595 842} fitmethod=entire");

If you do this before placing the text in the PDF you will get it as background image.

You may have a look at http://www.pdflib.com/pdflib-cookbook/images/ for more image related examples and check chapter 7.3 in the documentation “PDFlib-tutorial.pdf”.
