Ho provato col pacchetto lscape, quindi:
`
\documentclass[12pt]{report}
\usepackage{graphicx}
\usepackage[colorlinks=false]{hyperref}
\usepackage[a4paper,portrait,centering]{geometry}
\usepackage{lscape}
\begin{document}
\title{DRC Graphs}
\author{Michele Spinolo} %yourname
\pagestyle{empty} \maketitle \listoffigures
%IR Full range
\clearpage
\begin{landscape}
\begin{figure}
\includegraphics[width=0.95\textwidth,keepaspectratio,angle = -90]{L-IRFullRange}\\
\caption{Corrected and uncorrected
impulse response comparison. The corrected impulse response
becomes much similar to a bandlimited Dirac spike for about 1
ms. This implies a close to perfect phase response at least for
the early direct sound.}\label{L-IRFullRange}
\end{figure}
\end{landscape}
`
funziona bene, solo che:
-quando compilo con latex nel file .dvi la didascalia della foto rimane in formato portrait
-utilizzando dvi2pdf ottengo un PDF corretto ma le pagine in landscape vengono comunque visualizzare su schermo in verticale
🙁
