Document Classes ⇒ beamer | Frame Redefinition

[erotavlas]

Hi,

I have found an example of presentation made with beamer on the web that redefines the environment for the frame. The code is

Code: Select all

\newenvironment{lslide}[1] 
{\begin{frame}
{\begin{center}#1 
\end{center}}}
{\end{frame}}

I have read the beamer documentation, but I don't understand well some fields. In particular, at what do the fields [1] and #1 mean?

Thank you

The [1] indicates that the environment takes one argument (as opposed to 2 or 3 or none), and the #1 indicates where in the code the text from that (first) argument should go.

So if you write:

Code: Select all

\begin{lslide}{Argument}
Something here
\end{lslide}

This expands to:

Code: Select all

\begin{frame}
\begin{center}Argument
\end{center}
Something here
\end{frame}

So the #1 in the environment definition is replaced by the argument.

Ok, now it more clear. Another question: if I would like to modify the margin (top, bottom, left, right) of the slide to allow more text, how can I do?
It's better to change the newenvironment of the slide or to use

Code: Select all

\setbeamersize{text margin left=0.15cm,text margin right=0.15cm}

that works only for the left and right margins.

Thank you

Can somebody help me? Essentially, I would like to have more space on the slide. I need to write a lot of text.

You should not place to much content in a frame or a slide of a frame, respectively. Your audience wants to listen to you. You should have the major part of their attention with your remarks. So there is not much time to read all the content of a frame. The slides will complement your talk. I suggest to read Chapter 5 of the beamer user guide for some suggestions and guidelines on the structure of a presentation. You should reconsider any of your planned redefinitions of a frame.

Thank you for your tips, but my presentation is for an exam not for an audience. So I need to be clear on what I'm talking about.
Do you have any suggestions about the structure?

Thank
