如何将 \twopagepicture 移离外边距？

我使用此处发布的 \twopagepicture 片段。

如何在两页上添加图片，左侧部分在左侧，右侧部分在右侧（用于书籍）？

我需要进行一些小调整，使图形不与文档边缘接触，而是偏离边缘。垂直移动图形很容易，但每次我尝试调整时

\let\mywidth\paperwidth

到

\let\mywidth\paperwidth - <some offset>in

因此水平边缘向内延伸，中间图形的某些部分被剪掉。

这是未经我修改的 MWE。它往往对齐方式很奇怪，但对于我正在处理的主要文档来说没问题。

The diagonal in the picture should not be broken.

\twopagepicture{t}{p}{diagonal.png}{}

And the picture continues to the next page.

\end{document}

diagonal.png 是一张简单的图片。如果页面顶部和图片之间没有空格，或者线条断开，则无法按预期工作。

在有人认为我的问题是关于删除文件扩展名之前，这就是我想做的事情。 在此处输入图片描述

我采取的临时解决方案是制作一个宽度为两页长度的 PNG 文件，然后手动重新缩放图像 (JPG)。这几乎使图像的文件大小翻倍，因此理想情况下，我仍然希望在 LaTeX 中处理位置。

这个问题已经被@MartinScharrer 解决了 ---如何在两页上添加图片，左侧部分在左侧，右侧部分在右侧（用于书籍）？

请注意，您需要插入您选择的源图像，如下所示
