questions about exporting to latex using beamer documentclass

questions about exporting to latex using beamer documentclass

[Spike Spiegel]

Hi,

I have the following in my .emacs:

(add-to-list 'org-export-latex-classes
             '("beamer"
               "\\documentclass[11pt]{beamer}
\\usepackage[utf8]{inputenc}
\\usepackage[T1]{fontenc}
\\usepackage{hyperref}
\\usepackage{verbatim}
\\usetheme{Singapore}
\\usecolortheme{dove}"
               ("\\begin{frame}{%s}"
                "\\end{frame}"
                "\\begin{frame}{%s}"
                "\\end{frame}")))


and I'm having a hard time to figure out the solution to the following problems:
- there are no "section/subsection" tex commands added before the
frame one and I don't see how to add it in there since a section and
subsection can be in the same frame
- I'm in the situation that I need to pass options to an image
(\includegraphics) in a frame's title (frames are beamer's idea of
slide). Based on the docs it seems I should be doing something like
"#+ATTR_LaTeX: width=5cm,angle=90" but I can't put that within a
headline before the image and it won't work if I put it before it
because it'll end up outside of the frame
- I also need to include an image in the titlepage but I don't see any
way to override \maketitle other than maybe renewcommand'ing it, which
I tried with #+LaTeX_HEADER, but kept getting errors, altho that might
have been me. While poking around I noticed
org-export-latex-title-command in org-latex.el but I'm unsure how I'd
use that to achieve my goal.

On a side note, a little feature request: would it be possible to
produce an indented tex file? post editing is otherwise quite painful

thanks

Try
         C-x h C-M-\ 

or equivalently

        M-x mark-whole-buffer
        M-x indent-region

when editing the TeX file.

This can be done using beamer's \titlegraphic command. Add

#+LaTeX_HEADER: \titlegraphic{\includegraphics{foo.png}}

to your org file.

Both answers spot on, thanks, with just a minor problem: adding
\titlegraphic won't make the spacing between \title \author \data as
produced by \maketitle shrink so the entire slide is pretty much used
up and the image doesn't fit in. Is there a way to override that?

Wrt your reply in pvt to my other question, sorry if I wasn't clear.
Your suggestion of using \includegraphics straight into the heading
works just fine, my issue is that I was trying to do it the org way
and use a link (as in C-u C-c C-l) which would have then requried a
#+ATTR_LaTeX header to pass in the width parameter.

I did some more work last night and came across another issues:
- #BEGIN_VERBATIM won't work because to use the \begin{verbatim}
environment the \being{frame} requires [fragile]

Also, given a variable like org-export-latex-image-default-option, is
there any way to override it per file or per document class?

Last thing, if you're gonna use latex commands requiring paths to
files, how do you insert the path? using C-u C-l isn't really an
option as that will add a link and not just the path to the file so
then you have to delete the [[ ]].

thanks again for all the help

Yes - you should read sec. 16.3 (on templates) of the Beamer User Guide.
You can redefine the title page template and format the title page any
way you wish (within limits of course: it all has to fit on one slide).

For example, try adding this to the preamble (note that I made the image bigger, but
if it doesn't fit, you can use the same method to make it smaller):

,----
| \titlegraphic{\begin{center}\includegraphics[width=5cm]{foo.png}\end{center}}
| 
| \title{Example presentation}
| \author{Nick Dokos \\ $<$\href{mailto:nicholas.dokos@hp.com}{nicholas.dokos@hp.com}$>$}
| \date{04 July 2009}
| 
| \setbeamertemplate{title page}{
|  \centering{
|   \inserttitle\inserttitle\inserttitle\inserttitle\inserttitle\inserttitle\inserttitle\inserttitle \\
|   \insertauthor \\
|   \insertdate \\
|   \inserttitlegraphic}}
`----

You might also try asking questions about beamer on comp.text.tex (after
all, this has nothing to do with org-mode). I don't know if Till Tantau
hangs out there any longer, but you are still much more likely to get
answers to such questions there.

I worked around this when working on my presentation by putting verbatim stuff
in a file and using \verbatiminput:

,----
| #+LaTeX_CLASS: beamer
| #+TITLE: Example presentation
| #+AUTHOR: Nick Dokos \\ $<$\href{mailto:nicholas.dokos@hp.com}{nicholas.dokos@hp.com}$>$

| ** Reason 2.

Well, yes and no (mostly no - but see below):

o You can of course customize this variable, but that's a global setting.

o You can use the ":latex-image-options" property to set the above variable,
  but that is used in org-publish-project-alist, not for exporting. From org-exp.el:

,----
| (defconst org-export-plist-vars
|   '((:link-up		      nil	  org-export-html-link-up)
|     
|     ...
| 
|     (:latex-image-options     nil	  org-export-latex-image-default-option))
|   "List of properties that represent export/publishing variables.
| Each element is a list of 3 items:
| 1. The property that is used internally, and also for org-publish-project-alist
| 2. The string that can be used in the OPTION lines to set this option,
|    or nil if this option cannot be changed in this way
| 3. The customization variable that sets the default for this option."
| )
`----

o You can modify the setting of the org-export-plist-vars (either by modifying your copy
  of org-exp.el or by some other method) to change the line

     (:latex-image-options     nil	  org-export-latex-image-default-option))

  to

     (:latex-image-options     "latex-image-options"	  org-export-latex-image-default-option))

  and then use

     #+OPTIONS: latex-image-options:width=1cm

  in your org file.

  [BTW, if you are using git, small local variations from the canonical org-mode can be easily
   accommodated, by using a local branch and git rebase.]

o You can try to convince Carsten that this should be part of canonical org-mode.

Nick

Here's how I use "prosper", follow the examples below. After exporting
to tex, you must use the "latex" command (not pdflatex), followed by "dvipdf".

Enjoy!

~/.emacs:

(setq org-export-latex-classes (cons '("prosper"
"% BEGIN Prosper Defaults
\\documentclass[pdf, contemporain]{prosper}
\\usepackage[utf8]{inputenc}
\\usepackage[T1]{fontenc}
\\usepackage{hyperref}
\\hypersetup{colorlinks,linkcolor=blue}
% END Prosper Defaults

"
("\\begin{slide}{%s}"
"\\end{slide}"
"\\begin{slide}{%s}"
"\\end{slide}"))
org-export-latex-classes))

Ledger.org (see http://adamsinfoserv.com/ under Presentations):

You can now do (I think)

#+BIND: org-export-latex-image-default-option "width=1cm"

This will work for any variables that are not addressed by
#+OPTIONS and similar lines.  It will not work for anything
that is in `org-export-plist-vars', and that is confusing.
Any ideas on how these should interact?
