Image from \includegraphics showing in wrong image size
Image is not showing full width and height, it is showing 100% as single dot, when you zooming view this picture some what bigger. I also mentioned the width and height for the picture is not showing it correctly. Its always showing like this. What we do this in LaTeX? Please look at the two images.
\documentclass{article}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{float}
\begin{document}
Text
\begin{figure}[ht]
\centering
\includegraphics[scale=0.5]{pic3}
\caption{caption text}
\label{fig:image}
\end{figure}
\end{document}
