下载完成放入vendor 目录

参考例子：  
[https://tcpdf.org/examples/example\_027/][https_tcpdf.org_examples_example_027]

以下代码直接运行生成条码：

function createCode()
    { 
        /** * Creates an example PDF TEST document using TCPDF * @package com.tecnick.tcpdf * @abstract TCPDF - Example: 1D Barcodes. * @author Nicola Asuni * @since 2008-03-04 */
    
        require_once ROOT_PATH . '/vendor/tecnickcom/tcpdf/examples/tcpdf_include.php';
        $pdf = new \TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
        $pdf->SetCreator(PDF_CREATOR);
        $pdf->SetAuthor('Nicola Asuni');
        $pdf->SetTitle('TCPDF Example 027');
        $pdf->SetSubject('TCPDF Tutorial');
        $pdf->SetKeywords('TCPDF, PDF, example, test, guide');
    
        $pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE . ' 027', PDF_HEADER_STRING);
    
        $pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
        $pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
    
        $pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
    
        $pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
        $pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
        $pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
        $pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
    
    
        $pdf->setBarcode(date('Y-m-d H:i:s'));
        $pdf->SetFont('helvetica', '', 11);
        $pdf->AddPage();
    
    // $txt = "You can also export 1D barcodes in other formats (PNG, SVG, HTML).
    // Check the examples inside the barcodes directory.\n";
    // $pdf->MultiCell(70, 50, $txt, 0, 'J', false, 1, 125, 30, true, 0, false, true, 0, 'T', false);
    // $pdf->SetY(30);
    
    
        $pdf->SetFont('helvetica', '', 10);
        $style = array(
            'position' => '',
            'align' => 'C',
            'stretch' => false,
            'fitwidth' => true,
            'cellfitalign' => '',
            'border' => true,
            'hpadding' => 'auto',
            'vpadding' => 'auto',
            'fgcolor' => array(0, 0, 0),
            'bgcolor' => false, //array(255,255,255),
            'text' => true,
            'font' => 'helvetica',
            'fontsize' => 8,
            'stretchtext' => 4
        );
    
    // $pdf->Cell(0, 0, 'CODE 128 AUTO', 0, 1);
        $pdf->write1DBarcode('CODE 128 AUTO', 'C128', '', '', '', 18, 0.4, $style, 'N');
        $pdf->Ln();
        ob_end_clean();
        $pdf->Output();#直接输出
    	$pdf->Output(ROOT_PATH . 'public/example_027.pdf', 'F');#输入到文档
    }
