I need to import pdf
file into fpdf
and print it silently
. I use fpdi extension to load existing pdf, but I have no idea how to autoprint it.
This is how autoprint in fpdf works - 2 additional classes around fpdf (from their examples).
require('lib/fpdf/fpdf.php');
require('lib/fpdi-1.6.1/fpdi.php');
class PDF_JavaScript extends FPDF {
protected $javascript;
protected $n_js;
function IncludeJS($script, $isUTF8=false) {
if(!$isUTF8)
$script=utf8_encode($script);
$this->javascript=$script;
}
function _putjavascript() {
$this->_newobj();
$this->n_js=$this->n;
$this->_put('<<');
$this->_put('/Names [(EmbeddedJS) '.($this->n+1).' 0 R]');
$this->_put('>>');
$this->_put('endobj');
$this->_newobj();
$this->_put('<<');
$this->_put('/S /JavaScript');
$this->_put('/JS '.$this->_textstring($this->javascript));
$this->_put('>>');
$this->_put('endobj');
}
function _putresources() {
parent::_putresources();
if (!empty($this->javascript)) {
$this->_putjavascript();
}
}
function _putcatalog() {
parent::_putcatalog();
if (!empty($this->javascript)) {
$this->_put('/Names <</JavaScript '.($this->n_js).' 0 R>>');
}
}
}
class PDF_AutoPrint extends PDF_JavaScript
{
function AutoPrint($printer='')
{
// Open the print dialog
if($printer)
{
$printer = str_replace('\\', '\\\\', $printer);
$script = "var pp = getPrintParams();";
$script .= "pp.interactive = pp.constants.interactionLevel.full;";
$script .= "pp.printerName = '$printer'";
$script .= "print(pp);";
}
else
$script = 'print(true);';
$this->IncludeJS($script);
}
}
$pdf = new PDF_AutoPrint();
$pdf->AddPage();
$pdf->SetFont('Arial', '', 20);
$pdf->Text(90, 50, 'Print me!');
$pdf->AutoPrint();
$pdf->Output();
And it works fine, but I need it to combine with this:
require('lib/fpdf/fpdf.php');
//require('lib/fpdi-2.0.1/src/autoload.php');
require('lib/fpdi-1.6.1/fpdi.php');
$pdf = new FPDI();
$pdf->setSourceFile("BCEB_20171207_100_A_1_51.pdf");
$tplIdx = $pdf->importPage(1, '/MediaBox');
$pdf->addPage();
$pdf->useTemplate($tplIdx, 0, 0, 0, 0, true);
$pdf->Output();
I really have no idea how to combine both (with autoload
classes aroud fpdi?). Alternative that would help - another way to load ready pdf into fpdf and output it.
