TCPDF 背景圖片透明度

一、TCPDF 背景圖片透明度 

參考：https://bbs.csdn.net/topics/392364981

效果：

 

 

二、畫一條線：

2.1方法解說 

/*畫一條線：

       x1：線條起點x座標

       y1：線條起點y座標

       x2：線條終點x座標

       y2：線條終點y座標

       style：SetLineStyle的效果同樣

       */

//       $pdf->Line($x1, $y1, $x2, $y2, $style=array());

 2.2方法使用：

/*線的顏色*/
$this->SetLineStyle(array('width' => 0, 'cap' => 'butt', 'join' => 'miter', 'dash' => '0', 'color' => array(220, 20,60)));
/*畫一條線*/
$this->Line(1, 100, 100, 1, $style=array());

/*加入一條下劃線   下劃線顏色默認爲黑色，用此方法【SetLineStyle()】能夠自定義線的顏色  */
$this->Cell(180, 0, '', 1, 0, 'C', 0, '', 0, true);

2.3效果：

 

3.自定義頁眉頁腳：
