All the templates also contain the following commented lines:
// Add background image
//$pdf->Image(DOL_DOCUMENT_ROOT.'/core/modules/facture/doc/background1.png', 26, 90, 160, 110);
//$pdf->Image(DOL_DOCUMENT_ROOT.'/core/modules/facture/doc/background2.png', 56, 100, 100, 100);
If you uncomment one of the lines, you can add an image as background for the table of prices, as can be seen in the examples below. This can be useful if someone wants to include a highly transparent version of their logo or of a pattern, as background for the invoice, in order to personalize it.
