How do you change the image of a bullet point in LaTeX Beamer

Question

When I use the itemize environment, i.e.

\begin{itemize}      \item one     \item two     \item three \end{itemize} 

The bullet points are ugly bitmap graphics that have harsh (aliased) edges. I'd like it to be a nice, clean font character or vector graphic

Answer 1

You can simply set a symbol of your choice. Let me assume you'd like the \checkmark symbol, just write:

\begin{itemize}      \item[\checkmark] one     \item[\checkmark] two     \item[\checkmark] three \end{itemize} 

Furthermore, if it's too long to write, you can set a new command:

\newcommand{\myitem}{\item[\checkmark]} 

and the whole thing becomes:

\begin{itemize}     \myitem one    \myitem two    \myitem three \end{itemize} 

Otherwise, you can use the enumitem package as stated in the answer below.

For document classes other than beamer, there are two more ways to do the trick:

In the preamble, write:

\def\labelitemi{\checkmark} 

If you want to change the symbol in only one itemize environment, write:

\begin{itemize}  \newcommand{\labelitemi}{\checkmark}    \item one    \item two    \item three \end{itemize} 

Answer 2

Probably the best way is to use the beamer template:

\setbeamertemplate{itemize items}{\checkmark}
