I drew a glucose molecule (in its chair conformation) with the package tikz. And then I took a screenshot and edited it. After this I inserted this picture into my LaTeX document. The problem is the following: I would like the picture to start from the very left edge of the paper but unfortunatelly, it is not that easy for me because there is always a white space (about 1-2 cm). How to change this space to 0 cm?
A picture of my problem:
Here is the code:
\documentclass[12pt,a4paper]{article}
\usepackage[magyar]{babel}
\usepackage[utf8]{inputenc}
\usepackage{tikz,chemfig,mathtools,amsmath,amsfonts,amssymb,fullpage,graphicx,xcolor,cancel}
\usepackage[outline]{contour}
\definecolor{zold}{HTML}{99FF99}
\begin{document}
\begin{titlepage}
\vspace*{5cm}
\begin{center}
\textsc{\Huge Title}\\
\vspace*{1cm}
\textsc{\Large Author}\\
\begin{figure}[h]
\includegraphics[width=18cm]{nagyglcc2.png}
\end{figure}
\end{center}
\end{titlepage}


\noindentimmediately before thetixzpicturedoes not resolve the issue then, the problem is in how you are drawing the picture. You can try adding a bounding box to see the actual edges of the picture. For example, see Bounding box is larger than expected when drawing a curved path. Otherwise, please post the a complete MWE including\documentclassand the appropriate packages that reproduces the problem. – Peter Grill Oct 23 '16 at 19:59\includegraphics[...]{...}with\hspace*{-\dimexpr \oddsidemargin + 1in} \includegraphics[...]{...}, do you get what you want? – GuM Oct 23 '16 at 21:35
