# 一、頁邊距
```
$PDF_MARGIN_LEFT = 5;
$PDF_MARGIN_TOP = 30;//留給頁眉的空間
$PDF_MARGIN_RIGHT = 5;
$pdf->SetMargins($PDF_MARGIN_LEFT, $PDF_MARGIN_TOP, $PDF_MARGIN_RIGHT);
```
# 二、頁眉、頁腳
和設置字體一樣，頁眉頁腳設置后會對之后的所有頁有效
## 1、頁眉
```
//頁眉logo
$PDF_HEADER_LOGO = __DIR__."/image/logo.png";
//logo寬度
$PDF_HEADER_LOGO_WIDTH = 15;
//設置頁眉字體
$pdf->setHeaderFont(Array('stsongstdlight', '', '10'));
$PDF_HEADER_TITLE = "土豆剛（Potatog）";
$PDF_HEADER_STRING = "PDF生成示例\n基礎demo";
//頂部標題顏色
$headerColor = array(254,0,0);
//頁眉線條顏色
$headerLineColor = array(0,0,255);
$pdf->SetHeaderData($PDF_HEADER_LOGO, $PDF_HEADER_LOGO_WIDTH, $PDF_HEADER_TITLE, $PDF_HEADER_STRING, $headerColor, $headerLineColor);
```
如果也顯示頁眉
```
$pdf->setPrintHeader(false);
```
## 2、頁腳
```
//頁腳字體顏色 頁碼
$footerColor = array(254,0,0);
//頁腳線條顏色
$footerLineColor = array(0,0,255);
$pdf->setFooterData($footerColor, $footerLineColor );
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
```
效果圖
有時候為了方便，可以顯示坐標，網格
```
//坐標
$pdf->SetFont('stsongstdlight', '', 5, '', true);
for ($x = 5;$x < 205; $x += 5)
{
$pdf->Text($x, 0,".".$x);
}
for ($y = 5;$y <= 270; $y += 5)
{
$pdf->Text(0, $y,$y.".");
}
//網格線
$pdf->SetFont('stsongstdlight', '', 5, '', true);
for ($x = 5;$x < 205; $x += 5)
{
for ($y = 5;$y <= 270; $y += 5)
{
$pdf->Text($x, $y,".");
}
}
```
