Hi all,

If we want to introduce arbitrary LaTeX code at the very beginning of a
float environment, apart from the usual tricks of putting the code in
:caption or :placement, this solution I describe here is more from the
LaTeX side. I thik its advantages are more control and consistency from
the point of view of LaTeX, and the possibility of introducing code of a
certain complexity.

Well, you have to write some LaTeX code for the preamble, but it's
really not much :)

We have to define a global command \myenvcode{<arbitrary code>} (if we
want to add the code to all document floats environments), and also a
'Myenvcode' environment, with the same argument. The etoolbox LaTeX
package provides a number of hooks: \AtBeginEnvironment,
\AtEndEnvironment, etc., but if we want our arbitrary code to be at the
very beginning of the environment, it's safer to use the \@floatboxreset
hook. So, the code that we would have to add to our preamble would be (I
prefer to define the command and environment using the xparse syntax):

#+NAME: preamble
#+begin_src latex :exports none



#+begin_src latex :noweb yes :results raw
,#+LaTeX_HEADER: <<preamble>>

And here a few examples:

#+ATTR_LaTeX: :options {\centering\fbox{Code before a image}\par\vspace{1ex}}
#+CAPTION: This is a image
#+ATTR_LaTeX: :width .5\linewidth :placement [h]

#+ATTR_LaTeX: :options {\captionsetup{font={color=red}}}
#+CAPTION: This is a image
#+ATTR_LaTeX: :width .5\linewidth :placement [h]

#+latex: \myenvcode{{\centering\fbox{Code before a table}\par\vspace{1ex}}}
#+CAPTION: This is a table
#+ATTR_LaTeX: :placement [h] :booktabs t
| a | b | c | d | f |
| 1 | 2 | 3 | 4 | 5 |

#+latex: \myenvcode{}

Best regards,

Juan Manuel
