在横向模式下使用xhtml2pdf生成PDF

Question

如何使用xhtml2pdf创建一个三色的景观布局？

我试过这样的方法，但不起作用。我应该从一开始就使用框架吗？

@page {
    size: a4 landscape;

    @frame left {
        -pdf-frame-content: left;
        -pdf-frame-border: 1;
        width: 9.9cm;
        text-align: left;
    }
    @frame middle {
        -pdf-frame-content: middle;
        -pdf-frame-border: 1;
        width: 9.9cm;
        text-align: left;
    }
    @frame right {
        -pdf-frame-content: left;
        -pdf-frame-border: 1;
        width: 9.9cm;
        text-align: left;
    }
}

我不认为用xhtml2pdf可以做到这一点，即使它是基于reportlab的，它允许你这样做。

在处理了一段时间之后，下面的代码片段生成了下面的图像：http://imgur.com/d4zRH

xhtml2pdf现在支持景观，只需添加此样式即可。

<style>
@page {
    size: letter landscape;
    margin: 2cm;
}
</style>
