I am using a two-column document and I need a figure to cover both columns, hence I am using the figure* environment. The problem is that I need the figure on the first page of the document. It appears that the normal [htb!], etc have no effect. No matter what I try the image ends up on page number two.
\documentclass[DIV=calc, paper=a4, fontsize=11pt, twocolumn]{scrartcl}
\usepackage{graphicx, float}
\begin{document}
\section*{Secton1}
\begin{figure*}[hbt!]
\centering
\includegraphics[width=\textwidth]{Figure1.pdf}
\caption{\textsf{Figure Caption.}}
\label{fig:Figure1}
\end{figure*}
\end{document}
Any suggestions?
