titles
I created a title page with command:
\title
\author
but when I add in the page of the title some elements another page is created and the title is in that new page created. How can I join title and other element such as figures in only one page?
\begin{titlepage}
\includegraphics[width=0.25\textwidth]{Immagini/unict}
\title{Scelta di un progetto di investimento}
\author{Vincenzo Pomona \\ Salvatore Mazzarino}
\maketitle
\end{titlepage}
Edit
My document class is book
I think \author uses a minipage internally, so you can use something like
\author[me]{A. U. Thor\\[3mm]A. N. Other, J. Bloggs, J. Doe}
and forget \coauthors except you want to use them somewhere else.
If you use this construction, delete \insertshortinstitue form your style.
You don't have to do everything with tikz. In fact, it is not advisable. Draw the shaded region with tikz and type every thing else using titlepage environment. This way you get more control.
\documentclass{book}
\usepackage{tikz}
\usepackage[a4paper,margin=1in]{geometry}
\begin{document}
\begin{titlepage}
\centering \sffamily
\begin{tikzpicture}[remember picture,overlay]
\shade [top color=red,bottom color=blue] (current page.south west) rectangle (current page.north east);
\end{tikzpicture}
{\Huge\textcolor{white}{This is my book'stitle}}
\par\vspace{0.5in}
{\large \textcolor{white}{This is my subtitle}}
\par\vspace{\stretch{1}}
{\Large \textcolor{white}{Author XY}}
\par
\vfill
\textcolor{white}{\today}
\end{titlepage}
\end{document}
Best Answer
\maketitlemakes an additional title page; creating its owntitlepageenvironment. Just remove your\maketitle.The idea is either to a) create an automated title page with
\author,\title, etc. and\titlepage, OR b) create a hand-made title page with\begin{titlepage}...\end{titlepage}.If you delete
\maketitleand make your own title page, don't forget to fill in\titleand\authorin the preamble of your document (before\begin{document}, since the class file will probably use this information for headers and things like that.
