\abstract{ This meta-paper describes the style to be used in articles
  and extended abstracts for SIBGRAPI. It is actually a compromise
  between the ``classic'' SIBGRAPI style, and the IEEE Computer
  Society Press guidelines. Plain Tex, MS/Word and Latex
  implementations of the style are available by WWW. Note: authors of
  accepted papers may get further instructions from IEEE to use other
  styles and format. Please, use this one instead, even for the camera
  ready version of your paper.}

\maketitle

\section{Pages}

All papers and extended abstracts submitted to SIBGRAPI, including any
supporting documents, must be in English. The main font must be Times
10 point nominal size, with baselines 12 points apart. Knuth's
Computer Modern fonts may be used in place of Times.

The text must fit inside a rectangle 17.4 cm x 22.5 cm, without headers
or footers. Page numbers must be supressed in the final version. The
text must be formatted as two columns 8.3 cm wide, separated by 0.8 cm
of blank space.

The first page must display the paper title, the name and address of
the authors, and an abstract in English. The title must be centered
over the whole page, in 12 point boldface font. Author names must be
centered in 10 point font, small caps. Addresses must be centered in
10 point roman font. The abstract must be centered over both columns,
in 10 point font, indented 0.8 cm on both sides.

\section{Sections and paragraphs}

\subsection{Sections}

Section and subsection titles must be in boldfac, 10 pt, flush left.
There should be an extra 12 pt of space above each title, and 3 pt
below it.

\subsection{Paragraphs}

The first paragraph of each section should not be indented.  The first
line of each subsequent paragraph should be indented by 0.7 cm. There should
be no extra space between the paragraphs.

\section{Figures and captions}

Figures and tables may span one or both columns. Their captions should
be centered if less than one line, and justified on both margins
otherwise.  See Figure \ref{fig:quadrado}.

\begin{figure}[httbp]
  \begin{center}
  $
    \vbox{
      \hrule height 1pt
      \hbox to 2cm{%
        \vrule height 1cm depth 1cm width 1pt 
        \hss $\bullet$\hss
        \vrule height 1cm depth 1cm width 1pt 
      }
      \hrule height 1pt
    }
  $
  \end{center}
  \caption{A typical figure.}
  \label{fig:quadrado}
\end{figure}

In tables, do not use colored or shaded backgrounds. Avoid thick,
doubled, or unnecessary framing lines. When reporting empirical data,
do not use more decimal digits than warranted by their precision and
reproducibility.

\section{Images}

All images and illustrations included in the paper should be in
black-and-white, or in gray tones. The image resolution {\em on
paper} should be about 600 dpi for black-and-white images, and
150-200 dpi for grayscale images. Do not include images with
excessive resolution, as they may take hours to print, without any
visible difference in the result.

\section{References}

Bibliographic references must be unambiguous and in uniform style. We
recommend numbered references in brackets, e.g. Homer \cite{Iliad},
Arnold and Gosling \cite{Java}, or Euclid \cite{euc1,euc2}.

Ideally, a sentence should remain grammatically correct if all parts
within parentheses or brackets are deleted. This rule applies in
particular to reference and equation numbers; so one must not use
these tags as sentence words, as in ``see \cite{euc1} for a proof of
(3)''. If this rule cannot be obeyed, one should at least use the tags
only as qualifiers: ``see reference \cite{euc1} for a proof of formula
(3).''
