How can I add a page that takes the size of an A4 page in a document?
I use the package \usepackage[left=2.5cm,top=3cm,right=2.5cm,bottom=3cm,bindingoffset=0.5cm]{geometry}.
I tried to add it that way
\documentclass[14pt,twoside]{extreport}
\renewcommand{\baselinestretch}{1.4}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{color}
\usepackage{float}
\usepackage{amsfonts}
\usepackage{amsthm}
\usepackage{amsmath}
\usepackage{enumerate}
\usepackage{refstyle}
\graphicspath{ {images/} }
\usepackage[left=2.5cm,top=3cm,right=2.5cm,bottom=3cm,bindingoffset=0.5cm]{geometry}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhead{}
\fancyhead{}
\fancyhead[RO,LE]{\footnotesize \nouppercase{\leftmark}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
\begin{figure}[H]
\centering
\includegraphics[scale=1]{image}
\end{figure}
\thispagestyle{empty}
\chapter{chapter one}
\section{text}
\chapter{chapter two}
\section{text}
\end{document}
But the way failed in the image (extension pdf) move to the second page when zoomed. It is not A4 size.
The following images illustrate
The image should be on the front page of A4 size and there are no margins.
Please help, thank you anyway.



eso-picprovides a low level interface to add stuff to the background. There are other packages as well. – daleif Sep 08 '17 at 09:30eso-picor similar packages like @daleif suggested, see How to create a background image on title page with LaTeX? for further information. If you only want to have this image on a separate page, with no further text on it, usepdfpagesas proposed by @ingli. – diabonas Sep 08 '17 at 09:38eso-pic, e.g.tikzdoes provide means to put stuff in the background, too. – Skillmon Sep 08 '17 at 09:49
