用TCPDF定位h1,h2,h3和其他标签

Question

我正在尝试使用HTML代码与TCPDF制作PDF文档。

现在我使用下面的代码:

// set font
$pdf->SetFont('dejavusans', '', 36);
// add a page
$pdf->AddPage();
$html = '
<style>
.h1 {
color: #2B6999;
font-weight: normal;
}
</style>
<h1 class="h1">Test</h1>
';
// output the HTML content
$pdf->writeHTML($html, true, false, true, false, 'C');

如何定位文本?我不能在标签之间使用margin-top等。

有谁能帮我解决这个问题吗?

Answer 1

您可以添加如下内容:

$tagvs = array('h1' => array(0 => array('h' => 1, 'n' => 3), 1 => array('h' => 1, 'n' => 2)),
               'h2' => array(0 => array('h' => 1, 'n' => 2), 1 => array('h' => 1, 'n' => 1)));
$pdf->setHtmlVSpace($tagvs);

下面是来自文档/示例的格式说明:

文件:tcppdf.php:

/**
 * Set the vertical spaces for HTML tags.
 * The array must have the following structure (example):
 * $tagvs = array('h1' => array(0 => array('h' => '', 'n' => 2), 1 => array('h' => 1.3, 'n' => 1)));
 * The first array level contains the tag names,
 * the second level contains 0 for opening tags or 1 for closing tags,
 * the third level contains the vertical space unit (h) and the number spaces to add (n).
 * If the h parameter is not specified, default values are used.
 * @param $tagvs (array) array of tags and relative vertical spaces.
 * @public
 * @since 4.2.001 (2008-10-30)
 */

文件http://www.tcpdf.org/examples/example_061.phps:

// REMOVE TAG TOP AND BOTTOM MARGINS
//
// $tagvs = array('p' => array(0 => array('h' => 0, 'n' => 0), 1 => array('h' => 0, 'n' => 0)));
// $pdf->setHtmlVSpace($tagvs);
// 
// Since the CSS margin command is not yet implemented on TCPDF, you
// need to set the spacing of block tags using the above method.

您正在使用writeHTML，它准确地输出HTML，您需要使用" $pdf->Cell "函数。这里有很多例子http://www.tcpdf.org/examples.php
