指定页面顶部的图像

Question

我如何将图像放置在指定页面的顶部。例如，奇数页将由图像填充，甚至带有文本。或者，我只想确保 (lua)latex 将图像放置在第 2、3、6 页上？

这里讨论了类似的问题：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）？

Answer 1

以下是解决方案的一个版本如何使用 TikZ 和 graphicx 在左上角添加图像适用于仅在页面上添加指定的徽标2,3, and 6。它使用[some]选项包裹background​。

要更改放置图形的页面，只需更改定义中的值即可\ListOfPagesWithLogo。将该宏设置为：

\newcommand*{\ListOfPagesWithLogo}{2,3,6}

2您可以在、3和页面上获得徽标6：

笔记：

• 我使用该xstring包进行数值比较，因为我喜欢这种语法，但是可以进行调整以不再需要这种语法。
• 下面的版本放置了一张图片，但如果您希望包含外部图形，tikz可以取消注释该行。\SetBgContents
• 需要进行两次编译运行，第一次获取坐标，第二次进行实际绘图。
