Por que não consigo colocar minha figura onde quero?

Question

Tenho um texto e depois quero inserir uma figura. O texto quase termina na segunda página, então quero colocar a figura no topo da terceira página (logo depois do texto), mas não consigo. Eu li os comandos de posicionamento aqui:http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captionse tentei todas as opções diferentes (ou seja, \begin{figure}[t!], \begin{figure}[t], \begin{figure}[b], \begin{figure}[h], ...) mas a figura permanece no mesmo lugar no meio da terceira página. Eu quero que isso vá para o topo. O que estou perdendo? Aqui está o código:

Answer 1

Da forma como está, seu documento não contém texto suficiente para que o LaTeX coloque a figura no topo da página. Na primeira página, os carros alegóricos no topo são proibidos. Não há segunda página (de texto). Assim, tendo a figura deixada no final do documento, o LaTeX faz o que for necessário para colocá-la: coloca-a em uma página de carros flutuantes e, por padrão, isso significa que os carros flutuantes estão centralizados verticalmente na página.

Se você tiver mais texto após a figura, isso não acontecerá:

\documentclass[11pt]{article}
\usepackage{kantlipsum}% for the demo
\usepackage{amssymb,mathtools}% fixes/enhancements for amsmath (loads amsmath)
\usepackage[demo]{graphicx}
\usepackage{tikz}
\usepackage{amsthm}
\usepackage{fullpage}
\usepackage{algorithm}
\usepackage{algorithmicx}
\usepackage{algpseudocode}
\newtheorem{thm}{Theorem}
\newtheorem{thm1}{Theorem}
\theoremstyle{definition}
\usepackage{float}
\newtheorem{defn}{Definition}[section]
\floatname{algorithm}{Algorithm}
\newcommand{\euler}{e}
\newenvironment{claim}[1]{\par\noindent\underline{Claim:}\space#1}{}

Se quiser que a figura fique centralizada, adicione \centeringno início do figureambiente`.

Se esse for o final do seu documento, você pode adicionar \newpage\vfill\mbox{ }no final para forçar uma nova página vazia para a figura flutuar no topo.

Answer 2

\usepackage{float}

\begin{figure}[H]

Isso forçará o LaTex a colocar sua figura onde você deseja.
