Php TCPDF适合页面（缩小比例）

我在我的项目中使用TCPDF（第一次）。 在过去的两天里，我已经完成了PDF的创建和保存

我现在有一个问题。数据是动态生成的，高度会略有不同。有没有一种方法可以像MS office中用于缩放的选项那样“适合页面”

下面是PHP代码

function generateProformaContent($user,$quote,$datas)
{
    $datas=json_decode($datas);
    foreach($datas as $data)
    {
        foreach ($quote->products as $product)
        {
            if($data->productName==$product->name)
            {
                $product->totalPacks=$data->packs;
            }
        }
    }
    unset ($datas);
    $content=
