'Best Practice to Print Barcode In dompdf

I want to create a label sticker with barcode in PDF. Please give me the suggestion to create this things. Now , I use CI3 and dompdf.

I have tried googling a lot of time, but I am not found the best practice to realized this thing.

I followed your suggestion, Now I have folder in vendor/Piqcer.

I try this into my view_report like this:

<tr>
   <td class="solid" colspan="2">
      <?= $value->NO_URUT ?>
      <?php
          $generator = new \Picqer\Barcode\BarcodeGeneratorPNG();
          echo '<img src="data:image/png;base64,' . base64_encode($generator->getBarcode($value->NO_URUT, $generator::TYPE_CODE_128)) . '">';
      ?>
   </td>
</tr>

But I got error : 

Fatal error: Class 'Picqer\Barcode\BarcodeGeneratorPNG' not found

UPDATE

So, this library is on ci_folder\vendor\picqer\php-barcode-generator. Now I create an autoload library like this :

class Barcode {

public function generate($id) {
    require_once("./vendor/picqer/php-barcode-generator/src/BarcodeGeneratorJPG.php");
    $generator = new Picqer\Barcode\BarcodeGeneratorJPG();
    echo $generator->getBarcode($id, $generator::TYPE_CODE_128);
}

}

IN my controller :

$this->load->library('dompdfgenerator');
$this->load->library('barcode');

 $data = array(
        'result' => $result,
        'container' => $containers
    );

  $html = $this->load->view('members/megumi/check_list_per_tanggal/v_laporan_sticker_pilihan', $data, true);
  $this->dompdfgenerator->generate($html, "$identity");

Now in view :

<tr>
    <td class="solid" colspan="2">
     <?= $value->NO_URUT ?>
     <?php
        echo '<img src="data:image/png;base64,' . base64_encode($this->barcode->generate($value->NO_URUT)) . '">';
      ?>

     </td>
</tr>

It still : Fatal error: Class 'Picqer\Barcode\BarcodeGenerator' not found

Please advise...

Solution 1:[1]

Have you tried using libraries, such as PHP Barcode Generator. It will generate a barcode for you and export it as an SVG, PNG or JPG or HTML. You should just insert the resulting barcode to the HTML you wil lbe exporting with DOMPDF.

Solution 2:[2]

I think you may get some idea from this answer Integrate barcode reader generate/read with Codeigniter. Also note that the files of BarcodeGenerator are stored in the third_party folder of the application.
