Multicol y una caja flotante en la parte superior de la página, con el ajuste de texto alrededor de ella

Question

Estoy escribiendo un artículo para una revista. Estoy tratando de insertar un cuadro de 2 columnas (flotante) en la esquina superior derecha de un documento de 3 columnas, con el ajuste de texto alrededor de ella muy bien ANDN las columnas que se están alineados. Estoy haciendo la caja con el paquete TikZ para que pueda tener una caja con bordes redondeados y un color de fondo. Yo estaba tratando de hacer el envoltorio utilizando wrapfig (y he probado algunas cosas minipágina también), pero no puedo conseguir que funcione.

Este es un código que explica lo que estoy tratando de hacer, y como he estado tratando de hacerlo:

\documentclass{article}
\usepackage{wrapfig}
\usepackage{tikz}
\usepackage{multicol}

\definecolor{col}{rgb}{0.6,0.6,0.9}
\setlength{\columnsep}{0.5cm}
\newcommand{\floatingBox}[3]
{
 \noindent
 \begin{wrapfigure}{#1}{#2}
 \begin{tikzpicture}
 \node[rounded corners=5pt, fill=col, text width=\linewidth]{#3};
 \end{tikzpicture}
 \end{wrapfigure}
}

\begin{document}
\begin{multicols}{3}
\large
Some random rambling to fill a page.

Answer 1

Es mi experiencia que tal esquema (figura que abarca más de uno, pero no todas las columnas de la página) es difícil de obtener con el látex.

La mejor solución que yo sepa es la flowfram paquete. El paquete le permite definir el diseño de página (donde se deben colocar ciertas cajas) antes de escribir el contenido del documento.

Un pequeño ejemplo de código es la siguiente. Se trata de una reestructuración del ejemplo del cartel que viene con el paquete flowfram.

\documentclass[a4wide]{article}

\usepackage{color}
\usepackage{helvet}
\usepackage{flowfram}

\setlength{\columnsep}{0.3cm}

% Base the page layout on 3 column with static header.
\NcolumnStop{3}{1 cm}
% give the static frame a label to make it easier to keep track of
\setstaticframe{\value{maxstatic}}{label={title},backcolor=[cmyk]{0.64,0,0.95,0.40},textcolor=white}

% On the first page, replace last two columns with
% 2 columns and a static above
\setflowframe{2,3}{pages={>1}}

\computeflowframearea{2,3}
\twocolumnStopinarea[1]{0.3\ffareaheight}{\ffareawidth}{\ffareaheight}{\ffareax}{\ffareay}
\setstaticframe{\value{maxstatic}}{label={info},backcolor=[cmyk]{0.26,0,0.76,0},clear}

\setallflowframes{backcolor=[cmyk]{0.15,0,0.69,0}}

\raggedright
\setlength{\parindent}{15pt}

\begin{document}
\begin{staticcontents*}{title}
\begin{center}
\bfseries\Large Creating stuff in \LaTeX\par
\end{center}
\end{staticcontents*}

\pagestyle{empty}

\begin{staticcontents*}{info}
\begin{staticfigure}

The {flowfram} package is designed to enable you to create
frames in a document such that the 
contents of the {document} environment flow from one 
frame to the next in the order that they were defined.  
This is useful for creating posters
or magazines or any other form of document that does not 
conform to the standard one or two column layout.

\vfill

\caption{The commands used to define the frames for this document g.}
\protect\label{fig:thisdoc}
\end{staticfigure}
\end{staticcontents*}

This is a modified version of the manual for the {flowfram} 
package.  It is intended to illustrated what can be done. See the 
full manual (ffuserguide.pdf) for
a comprehensive description, as this may now be out of date. 
The commands used to define the frames for
this document are shown in Figure~\ref{fig:thisdoc}.
If the columns are very narrow, it may be better to
use {raggedright}, otherwise \TeX\ may have a
problem working out the line breaks.

\section{Introduction}

The {flowfram} package is designed to enable you to create
frames in a document such that the 
contents of the {document} environment flow from one 
frame to the next in the order that they were defined.  
This is useful for creating posters
or magazines or any other form of document that does not 
conform to the standard one or two column layout.

\section{Setting up Frames}

The {flowfram} package provides three types of frame:
{flow frames}, {static 
frames} and {dynamic frames}.

\subsection{Flow Frames}

The flow frame is the principle type of frame.
The text of the {document} environment will flow from 
one frame to the next in order of definition. Each 
flow frame has an associated width, height, 
position on the page, and optionally a border.

It is recommended that all the flow frames in a document
have the same width, otherwise problems may occur
when a paragraph spans to flow frames of unequal
widths. This is because \TeX's output routine does not
register the change in {hsize} until it reaches
a paragraph break. If it is absolutely necessary for 
flow frames to have unequal widths, judicious use of
{framebreak} is required.

Answer 2

no flotantes cifra que abarca dos columnas en el ambiente multicol

He tenido un problema similar. El minipágina era el mejor idea que he oído.

También se puede hacer con wrapfig, pero se necesita una gran cantidad de ajuste, pero es posible:

Using wrapfig to span multiple columns

Wrapfig can't automatically make matching cutouts in adjacent columns
because it doesn't know which text will land in just the right place
in the column next-door.  It certainly can't handle floating in such
situations!  

Here are some methods for doing such layout "by hand".  They are
practical for one or a few such figures where you can tweak the
layout for the final copy.  It is too painful to do this for long 
or frequently-revised documents.  If you do have multiple fiddling, 
fix the first one in each chapter (or after any forced page break), 
rerun, then fix the second, etc.

(These examples use calc.sty to evaluate overhangs in place.)

Cutouts in Matching Columns

~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~X  ~~~~~~~~~~~~~~~~~Y
~~~~~~~~~                    ~~~~~~~~~
~~~~~~~~~                    ~~~~~~~~~
~~~~~~~~~                    ~~~~~~~~~
~~~~~~~~~                    ~~~~~~~~~
~~~~~~~~~                    ~~~~~~~~~
~~~~~~~~~                    ~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~

Initially, write the document without the wrapfigure, and locate the
desired natural linebreak at "X".  (This first step is used for all
methods described here.)  Then change to

~~~~~~~~X
\begin{wrapfigure}[6]{r}[.5\width+.5\columnsep]{6cm}
...
\end{wrapfigure}
~~~~....

and run LaTeX again. This will print the figure overlapping the right
column, but no matter. Use this run to locate position "Y" in the text.
For the final run, switch to: 

~~~~~~~~X
\begin{wrapfigure}[6]{r}[.5\width+.5\columnsep]{6cm}
...
\end{wrapfigure}
~~~~....
...~~~~~~~Y
\begin{wrapfigure}[6]{l}[.5\width+.5\columnsep]{6cm}
\vfill
\end{wrapfigure}
~~~~~~~~~~~


Taking a whole column plus a cutout

~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~X  ~~~~~~~~~~~~~~~~~Y
~~~~~~~~~  
~~~~~~~~~  
~~~~~~~~~  
~~~~~~~~~  
~~~~~~~~~  
~~~~~~~~~  
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~

Locate "X" first, without any figure, as above, then write the 
document like:

~~~~~~~~X
\begin{wrapfigure}[6]{r}[\columnwidth+\columnsep]{9cm}
...
\end{wrapfigure}
~~~~....

and ignore the overprinting of the right column.  Then, after locating
"Y" in the text, switch to:

~~~~~~~~X
\begin{wrapfigure}[6]{r}[\columnwidth+\columnsep]{9cm}
...
\end{wrapfigure}
~~~~....
...~~~~~~~Y\vspace{6\baselinskip}
~~~~~~~~~~~
for the final layout 


a whole column preceding a cutout

~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~X  ~~~~~~~~~~~~~~~~~Y
                             ~~~~~~~~~  
                             ~~~~~~~~~  
                             ~~~~~~~~~  
                             ~~~~~~~~~  
                             ~~~~~~~~~  
                             ~~~~~~~~~  
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~

After locating "X", write the draft document like:

~~~~~~~~X\vspace{6\baselinskip}
~~~~....
~~~~~~~~~~~~~
~~~~~~~~~

run LaTeX to locate "Y", and then switch to:

~~~~~~~~X\vspace{6\baselinskip}
~~~~....
~~~~~~~~~~~~~Y
\begin{wrapfigure}[6]{l}[\columnwidth+\columnsep]{9cm}
...
\end{wrapfigure}
~~~~~~~~~

Spanning (parts of) three columns

~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~X  ~~~~~~~~~~~~~~~~~Y  ~~~~~~~~~~~~~~~~~Z
~~~~~~~~~                                        ~~~~~~~~~
~~~~~~~~~                                        ~~~~~~~~~
~~~~~~~~~                                        ~~~~~~~~~
~~~~~~~~~                                        ~~~~~~~~~
~~~~~~~~~                                        ~~~~~~~~~
~~~~~~~~~                                        ~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~  ~~~~~~~~~~~~~~~~~~

This uses a combination of the above.  First locate X, then use

~~~~~~~~X
\begin{wrapfigure}[6]{r}[.5\width+.5\columnwidth+\columnsep]{12cm}
...
\end{wrapfigure}
~~~~....

Locate Y from this, and change to

~~~~~~~~X
\begin{wrapfigure}[6]{r}[.5\width+.5\columnwidth+\columnsep]{12cm}
...
\end{wrapfigure}
~~~~....
~~~~~~~~~~~~Y\vspace{6\baselineskip}
~~~~~~~....

which allows you to locate Z, to end up with 

~~~~~~~~X
\begin{wrapfigure}[6]{r}[.5\width+.5\columnwidth+\columnsep]{12cm}
...
\end{wrapfigure}
~~~~....
~~~~~~~~~~~~Y\vspace{6\baselineskip}
~~~~~~~....
~~~~~~~~~~~~Z
\begin{wrapfigure}[6]{l}[.5\width+.5\columnwidth+\columnsep]{12cm}
\vfill
\end{wrapfigure}




(Of course, to do matching cut-outs properly requires typesetting
the text to a grid.)

Esto es a partir de la documentación wrapfig. Buena suerte.
