TCPDF - 标题图像仅显示在第一页上

问题描述

我正在使用 TCPDF 生成一个 2 页的 pdf 文档.

I am using TCPDF to generate a 2 page pdf document.

我在文档中添加了页眉和页脚.页眉和页脚的文本部分正确显示在每个页面上，但是当我在页眉中包含图像徽标时，它仅显示在第一页上.

I have added a header and a footer to the document. The text part of the header and footer shows up correctly on each page however when I include an image logo in the header it is only showing up on the first page.

   public function Header()
{
    $this->Image('/home/xxxxxx/public_html/xxxxxxxx/uploads/logo/logo.png',10,6,0,13);

    $this->SetFont('helvetica','B',20);
    $this->Cell(80);
    $this->Cell(0,0, $project->name . ' - Project Plan',$frame,0,'R');
    $this->Ln(8);
    $this->SetFont('helvetica','',10);
    $this->Cell(0,0, $organisation->name,$frame,0,'R');
    $this->Ln(10);
}

有人知道我在这里做错了什么吗?

Does anyone have any idea what I am doing wrong here?

谢谢

推荐答案

我认为与页眉/页脚无关，但我认为 TCPPDF 存在破坏 Image 功能的错误，如此处报告的那样多次加载相同的图像文件 TCPD - 图片只显示一次

I think is not related to header/footer, but I think TCPDF has bug that broken Image function with same image file loaded multiple times as reported here TCPDF - image displayed only once

错误也存在于实际版本 tecnickcom/tcpdf:6.2.26

bug also present on actual version tecnickcom/tcpdf:6.2.26

我通过在外部加载图像并作为字符串传递给函数来解决这个问题.

I resolve this problem by loading image outside and pass to the function as string.

public function Header()
{
    $this->Image('@'.file_get_contents('/home/xxxxxx/public_html/xxxxxxxx/uploads/logo/logo.png'),10,6,0,13);

    $this->SetFont('helvetica','B',20);
    $this->Cell(80);
    $this->Cell(0,0, $project->name . ' - Project Plan',$frame,0,'R');
    $this->Ln(8);
    $this->SetFont('helvetica','',10);
    $this->Cell(0,0, $organisation->name,$frame,0,'R');
    $this->Ln(10);
}
