我正在创建自定义投影仪主题，但在幻灯片标题中插入图形时遇到了问题。
对于图形，我已将.eps文件导出到 Ti钾使用 Inkscape 编写的 Z 代码，效果很好。对于标题页的页眉和普通页的页眉，我都有一张单独的图像。我想将它们放在每张幻灯片的顶部，顶部、左侧或右侧没有空格，但也不重叠。
根据我使用的方法，生成的图像要么太小且未正确对齐，要么太大导致图像被剪切，这也是我不希望的。
您能为我的问题提供解决方案吗？
为了更好地说明，我提供了一个示例代码：

答案1
首先，你缺少一些%让你的 tikz 图片正确缩放到全纸宽度的东西。看看这SE 问题，了解有关为什么需要这样做的更多信息。这个问题解决了，我建议将您的 tikz 图片放在背景模板中。我认为这会让事情变得容易得多。要将标题框自动设置为纯色并更改背景，我认为只需重新定义命令就很有意义maketitle。
