TCPDF：有时添加新页面然后下一页内容溢出-Java 学习之路

我必须使用tcpdf库创建一个pdf . 我在下一页面临关于内容溢出的问题 . 有时添加新页面然后下一页内容溢出 . 该问题产生了几页 .
MY PHP CODE
public function getPdfToAllEmpReport(){

    //header("Content-type:application/pdf");

我遇到了同样的问题，这个问题的工程解决方案最终结合了魔术常量和 addPage 的用法，如果我的计算显示我们应该进行手动分页：
```
$top_margin = 82;
[...]
if ($pdf->getY() > (300 /* A4 height */ - $top_margin + 40 /* another magic constant */)) {
    $pdf->addPage();
}
```
写完每一行后 . 在你的情况下，你可能需要调整常量，但这解决了我的问题 .

它看起来像一个bug，该库愿意在页面区域的末尾写入 . 我不认为，我们可以解决这个问题，因为作者已经开始开发新的PDF库tc-lib-pdf .
