TCPDF add line across page in header
提问by Billy
I have created a custom header for my PDF created with TCPDF. Now I would like to add a blue line (about 2px width) that goes across the page at the bottom of the header but can't figure out how?
我为我用 TCPPDF 创建的 PDF 创建了一个自定义标题。现在我想在页眉底部添加一条穿过页面的蓝线（约 2px 宽），但不知道如何做？

I believe you do it like this:
我相信你是这样做的：
$style = array('width' => 0.5, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(255, 0, 0));
$pdf->Line(5, 10, 80, 30, $style);
Here is the full example
这是完整的例子

You can also use the page axis:
您还可以使用页面轴：
$pdf->Line(5, $pdf->y, $pdf->w - 5, $pdf->y);
However if you are trying to render a colored <hr>html tag you will need to adjust the TCPDF::DrawColor(this excerpt is from code that adds a graph bar to each row of a data report as per $twidthand $lengthmm):
但是，如果您尝试呈现彩色<hr>html 标记，则需要调整TCPDF::DrawColor（此摘录来自根据$twidth和向数据报告的每一行添加图形条的代码$lengthmm）：
$htmlbar = '<hr style="width:' . $lengthmm . 'mm;">';
$oldDrawColor = $pdf->DrawColor;
$pdf->setDrawColor(121, 161, 46);
$pdf->MultiCell($twidth,'2',$htmlbar,0,'L',$fill,1,'','',true,0,true,false,4,'T',false);
$pdf->DrawColor = $oldDrawColor;

I found the easiest way to put line
我找到了最简单的放置线的方法

Just add some HTML : )
只需添加一些 HTML :)
$html ='<hr>';
$pdf->writeHTML($html, true, false, true, false, '');

The point is to get the x value for the second point. This is how I do it:
重点是获取第二个点的 x 值。这就是我的做法：
$pageWidth = $pdf->getPageWidth(); // Get total page width, without margins
$pageMargins = $pdf->getMargins(); // Get all margins as array
$headerMargin = $pageMargins['header']; // Get the header margin
$px2 = $pageWidth - $headerMargin; // Compute x value for second point of line
$p1x = $this->getX();
$p1y = $this->getY();
$p2x = $px2;
$p2y = $p1y; // Use same y for a straight line
$style = array();
$this->Line($p1x, $p1y, $p2x, $p2y, $style);
