I am trying to use textpos to position images at specific location on
a frame.
I would like something like this in the beamer export:
\begin{textblock}{10}(3,3) \visible <2-> {
\includegraphics[width=.9\linewidth]{scatterplot2.png}
} \end{textblock}
I have defined the following beamer environment.
(add-to-list 'org-beamer-environments-extra
'("textpos1" "w" "\\begin{textblock}{%h}(3,3) \\visible %a {" "} \\end{textblock}"))
The problem is (3,3) is fixed in the above specification. How can I
specify it for a given headline? I have tried various ways of
generalising this but nothing seems to work.
For example, if I use the following:
(add-to-list 'org-beamer-environments-extra
'("textpos1" "w" "\\begin{textblock}%h \\visible %a {" "} \\end{textblock}"))
and write the headline as {10}(3,3), I get \{10\}(3,3) in beamer
export rather than {10}(3,3).
How does one use the escape %o? I have looked through ox-beamer.el,
worg and mailing list archives, but could not find a clear
explanation. Will be grateful for a pointer.

I now use TikZ to do that. I have the impression it is easier. Though, I have
the real impression of writing LaTeX inside an Org buffer... which I dislike.
I'd like to write text as text, and still get the ability to convert that to
HTML, for review, even if the layout wouldn't be (at all) the same.

You normally could use such a block (the old "org-special-blocks", now
integrated in Org 8 -- thanks Nicolas):
--8<---------------cut here---------------start------------->8---
#+begin_textblock
Contents
#+end_textblock
--8<---------------cut here---------------end--------------->8---

Though, the problem stays the same with what I think is the right way to do
it...
See how Org gets converted to LaTeX:
--8<---------------cut here---------------start------------->8---
#+begin_myenvironment \begin{myenvironment}
Test of a new Test of a new
environment. environment.
#+end_myenvironment \end{myenvironment}
--8<---------------cut here---------------end--------------->8---
That's OK. But the environment had no parameters.
--8<---------------cut here---------------start------------->8---
#+begin_myenvironment{3} \#+begin\_myenvironment\{3\}
Test of a new Test of a new
environment. environment.
#+end_myenvironment \#+end\_myenvironment
--8<---------------cut here---------------end--------------->8---
That's completely invalid LaTeX.
--8<---------------cut here---------------start------------->8---
#+begin_myenvironment {3} \begin{myenvironment}
Test of a new Test of a new
environment. environment.
#+end_myenvironment \end{myenvironment}
--8<---------------cut here---------------end--------------->8---
That's valid LaTeX, but the arguments of the environment have been ignored!
IIRC, that's how we did before, with the original `org-special-blocks' file.

I've no idea. I wonder as well how we do this.

I think we should changes some environment placeholders:
+ Introduce %r which would stand for the raw headline (without any
processing)
+ %H and %U would use the raw headline text instead.
The previous definition would become:
'("textpos1" "w" "\\begin{textblock}%r \\visible %a {" "} \\end{textblock}")
WDYT?

This should work with a recent Org.
There is also:
#+attr_latex: :options {3}
#+begin_myenvironment
Test of a new
environment
#+end_myenvironment

I'm not sure to understand. Where would he put his options? Directly on the
heading line, with no "text", then?
Something like this:
--8<---------------cut here---------------start------------->8---
** {10}(3,3) :textpos1:
Contents to position
at some (x,y) coordinates...
--8<---------------cut here---------------end--------------->8---

What do you call a recent Org? I'm blocked on commit 26a9b02, from May 27th,
as long as the #+SETUPFILE: bug is not fixed (fontification is broken).
So, is that one (4 weeks old) a recent Org?

Aahh! I wasn't aware (enough) of that way to pass my arguments to my own
environments. Thanks a lot, that works like a charm!

I think this is quite elegant...
With what you say below, we then have 3 different solutions (at least) for new
environments:
- the one above, where you add a new environment definition (but, then, it's
kind of private for your own files; difficult to share)
- the Org special blocks, ancient way, which you've fixed
#+begin_myenv{2cm}
Contents...
#+end_myenv
- the Org special blocks, new way, with the OPTIONS
#+LaTeX_ATTR: :options {2cm}
#+begin_myenv{2cm}
Contents...
#+end_myenv
Now, a big question: outside the fact that some such "standards" (like
"texpos1") would have to be added IMHO as default Beamer environments, what
about standard LaTeX?
I think normal, then, to wanna get that same behavior in the LaTeX backend.
How to do that? I'm a bit puzzled by the differences to get some similar
results...
- In LaTeX, you have the inline tasks which can be used to insert blocks, but
not the system where you create blocks by adding an "ignoreheading" heading,
right?
- In Beamer, we have both? And, for whatever reason (which must escape me),
we tend to prefer the "ignoreheading" for closing a block.
In my latest slides, I've been quite disturbed by how much "pure LaTeX" I've
finally inserted in my slides, for inserting TikZ nodes to render boxes. I had
the impression to write LaTeX inside an Org file; and that's not the right
approach:
- too much LaTeX tag overload,
- no HTML equivalent for the contents of my boxes -- while, as presented here
above for the "textpos", even in HTML, it'd be quite nice.
- no Org syntax usable: inside my boxes (TikZ nodes), I had to use \textbf for
bold, not the stars...
Now, there are, once again, other extra solutions: MACRO and Org Babel calls.
Too much solutions...

If you use advanced features of Org, you're more or less bound to share
your documents with a config file anyway.

I don't understand your question. Equivalent blocks do not exist in
standard LaTeX, do they? Also, this has nothing to do with inlinetasks.
In Beamer export, headlines can generate blocks. This is handy because
they can be easily nested, accept properties through drawers, etc.
Special blocks are more limited. Though, you cannot close a headline, so
the "ignoreheading" trick was implemented.
In LaTeX export, headlines generate headlines.

I think you are asking too much for Org syntax.

Indeed.

I realize that the patch won't fix it. This patch was introduced to
allow something like:
#+begin_figure*
...
#+end_figure*
again. But it still expects the same string after the "begin_" and the
"end_". In this case strings are different because of the arguments to
the environment.
Therefore, the correct way to set this is using the #+attr_latex line,
as in your first case.
I hope it is less confusing now.

It is. And one solution is enough... ;-)
Moreover, I guess putting the arguments on a LaTeX line makes it more
portable: what would happen with those arguments for HTML, for example? Here,
a simple "mychangemargin" DIV won't hurt.
