投影机类中帧标题的间距

Question

请参考附图。我正在使用 IIT Roorkee 的 beamer 类和 latex 模板制作演示文稿。框架标题“本学期完成的工作”超出水平蓝线太多。我想将其居中，使标题上方和标题下方的空白几乎相同。我该怎么做？

latex代码如下：

\documentclass[compress]{beamer}

\usetheme{IITR} % To use the theme of IITR for beamer class in Latex
\usepackage{ragged2e}
\apptocmd{\frame}{}{\justifying}{}

\usepackage{url}

Answer 1

问题是，您的主题通常有一个标题，但您用 禁用了它\setbeamertemplate{headline}{}，因此缺少了通常由标题占用的空间。为了弥补剩余的空间，我建议\setbeamertemplate{headline}{\vskip3pt}改为（您可能需要尝试垂直空间的确切值）

其他几点：

• \usepackage{graphicx}对于 beamer 来说没有必要

• 不要像\LARGE宏参数那样手动输入格式化指令，而是更改相应的字体：\setbeamerfont{frametitle}{size=\LARGE,series=\bfseries}

• 如果插入定义了高度和宽度的图像，请添加\keepaspectratio，否则图像将会扭曲。

\setbeamertemplate{headline}{\vskip3pt}

\setbeamertemplate{frametitle}{%

\usebackgroundtemplate{\includegraphics [width=\paperwidth,height=\paperheight,keepaspectratio]{YdRyj}}
