Graphics, Figures & Tables ⇒ picture centered vertically

[modenese]

Hi all,

I am a new user and I am trying to include my first picture in a latex document. I have coded something like this:

Code: Select all

\begin{figure}[lineheight]
  \vspace{-20pt}
  \centering
    \includegraphics[scale=0.45]{JKR.eps}
  \vspace{-20pt}
  \caption{JKR theory versus Hertz theory}
  \label{fig:JKR}
  \vspace{-10pt}
\end{figure}

The problem is that whatever I set the parameters you see in the code above, I always obtain my picture placed in the center of the page (vertically, I mean).
How can I avoid that? I want the picture in the center but only horizontally.

Thanks for your help (sorry if the question is too basic).

Regards,
Chiara

At first, the figure environment only accepts certain placement parameters, not what you inserted. For your purpose you have to modify an internal register to get your float placed on top of a page in case that the page only contains this float [1]. (It is then call a float page.)

Code: Select all

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[font=small,labelfont=bf,tableposition=top]{caption}
\usepackage{graphicx}

\makeatletter
\setlength{\@fptop}{0pt}
\makeatother

\begin {document}
  \begin{figure}[!p]
    \centering
    \includegraphics[scale=0.45]{JKR}
    \caption{JKR theory versus Hertz theory}\label{fig:JKR}
  \end{figure}
\end{document}

This modification will affect all floats that are placed on a float page, whether this placement is intended (as above) or not (caused by necessary floating).
