PDF Template Barcode Generator

👨‍💻 Development Help

Hi, I am trying to insert a barcode generator inside of PDF Template.
There is a online generator https://barcode.tec-it.com/en/PDF417?data=Test that i can insert in the html but this generates an image when I create a template, not when I create the PDF.

<img alt='Barcode Generator TEC-IT'
   src='https://barcode.tec-it.com/barcode.ashx?data=**$aos_quotes_number**&code=PDF417&multiplebarcodes=false&translate-esc=false&unit=Fit&dpi=96&imagetype=Gif&rotation=0&color=%23000000&bgcolor=%23ffffff&codepage=&qunit=Mm&quiet=0'/>

Is there around this problem or another way to add the barcode in to the pdf?

You can check and modify the PDF generation code in the following file.

modules/AOS_PDF_Templates/generatePdf.php

To create PDF files with barcodes, you can use the TCPDF or FPDF libraries. These libraries allow you to add barcodes directly to PDFs, including PDF417. There’s no need to look for additional services.

Here’s how it works with TCPDF:

$pdf = new TCPDF();
$barcode = $pdf->serializeTCPDFtagParameters(array('Test 18', 'PDF417', '', '', 50, 30, 0.4, array('position'=>'C', 'border'=>false, 'padding'=>4, 'fgcolor'=>array(0,0,0), 'bgcolor'=>array(255,255,255), 'text'=>true), 'N'));
$pdf->writeHTML('<tcpdf method="write1DBarcode" params="'.$barcode.'" />');

For HTML-to-PDF, there are cool JavaScript libraries like JsBarcode and bwip-js. They generate barcodes on the client-side and then convert them to PDF. This is convenient for modern web applications.
