I'm working on a beamer theme in which the title page should have the graphic on top. By reading beamerinnerthemedefault.sty
I thought I could accomplish this by setting the title page
template.
Here is an MWE:
\documentclass{beamer}
\title{Lorem Ipsum}
\subtitle{Ut molestie eros sed enim}
\author{Aspasius Protus}
\date{June 26, 2023}
\usepackage{lipsum}
\titlegraphic{graphic}
\setbeamertemplate{title page}{
\vbox{}
\usebeamertemplate{titlegraphic}
\vfill
\begingroup
\centering
\usebeamertemplate{title}
\vskip1em\par
\usebeamertemplate{author}
\usebeamertemplate{institute}
\usebeamertemplate{date}
\endgroup
}
\begin{document}
\maketitle
\end{document}
The document compiles successfully with no errors or warnings, but the title page comes out blank. Here is the log file.
I must be misunderstanding something about how \setbeamertemplate
works without a predefined option. But what?
titlegraphic
,title
,author
,institute
anddate
templates are new.
