如何使用 TCPDF 将 HTML 转换为 PDF？

Question

我将如何编写一个 div （例如， style="postion:absolute; width: 200px; height: 100px; border:olid 1px #000;"）并在其中输入一些文本？

Answer 1

利用 TCPDF 库的 writeHTML 函数。

<?php

require_once('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 049');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');

$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.' 049', 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);

if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
    require_once(dirname(__FILE__).'/lang/eng.php');
    $pdf->setLanguageArray($l);
}
$pdf->SetFont('helvetica', '', 10);

$pdf->AddPage();


$html = '<h1>Test TCPDF Methods in HTML</h1>
<h2 style="color:red;">IMPORTANT:</h2>
<span style="color:red;">If you are using user-generated content, the tcpdf tag can be unsafe.<br />
You can disable this tag by setting to false the <b>K_TCPDF_CALLS_IN_HTML</b> constant on TCPDF configuration file.</span>
<h2>write1DBarcode method in HTML</h2>';

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array('CODE 39', 'C39', '', '', 80, 30, 0.4, array('position'=>'S', 'border'=>true, 'padding'=>4, 'fgcolor'=>array(0,0,0), 'bgcolor'=>array(255,255,255), 'text'=>true, 'font'=>'helvetica', 'fontsize'=>8, 'stretchtext'=>4), 'N'));
$html .= '<tcpdf method="write1DBarcode" params="'.$params.'" />';

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array('CODE 128', 'C128', '', '', 80, 30, 0.4, array('position'=>'S', 'border'=>true, 'padding'=>4, 'fgcolor'=>array(0,0,0), 'bgcolor'=>array(255,255,255), 'text'=>true, 'font'=>'helvetica', 'fontsize'=>8, 'stretchtext'=>4), 'N'));
$html .= '<tcpdf method="write1DBarcode" params="'.$params.'" />';

$html .= '<tcpdf method="AddPage" /><h2>Graphic Functions</h2>';

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array(0));
$html .= '<tcpdf method="SetDrawColor" params="'.$params.'" />';

$params = TCPDF_STATIC::serializeTCPDFtagParameters(array(50, 50, 40, 10, 'DF', array(), array(0,128,255)));
$html .= '<tcpdf method="Rect" params="'.$params.'" />';
$pdf->writeHTML($html, true, 0, true, 0);

$pdf->lastPage();
$pdf->Output('example_049.pdf', 'I');

?>

下面的代码片段仅显示了生成 div 的相关代码，并假设您已经初始化了 pdf 文档并使用 $pdf 作为句柄。此外，确切的尺寸（阅读：像素位置/大小）不会直接转换为 tcpdf，因此您可能需要稍微尝试一下。请参阅此处的 TCPDF writeHTMLCell 文档。

$borderStyle=array();
$borderStyle['cap']='butt';
$borderStyle['color']=array(0,0,0);
$borderStyle['dash']=0;
$borderStyle['join']='';    
$borderStyle['phase']=0;
$borderStyle['width']=1;

$divHeight=100;
$divWidth=200;

$divXPosition=15;
$divYPosition=80;

$pdf->writeHTMLCell($divWidth, $divHeight, $divXPosition,$divYPosition,$html, $borderStyle);
