Thanks to every one. Problem was with my miktex installation. I re installed the same and now XeLaTeX works fine. And it is great with full freedom with fonts. Neverthless I have a query with the experts. %========================================= It seems the xelatex will not accept figures in .pdf format. Also, there is mismatch in fonts of figures and rest of the document, if I include figures as .png file. So I am planning to put .pgf/.tikz files directly as \input{myfigure.tikz} . This is the trouble for me. I do not know how to control the dimensions of the figure in this case. If I use ---------------------------------------- \begin{figure}[h] \centerline{\includegraphics[*width=0.575\textwidth* ]{wavemechanics-fig/Figures/gammaraymicroscope.pdf}} \caption{$\gamma-$ ray microscope} \label{fig:gammaraymicroscope} \end{figure} ---------------------------------------- it is fine. But that won't do the job for \input{gammaraymicroscope.pgf}. ---------------------------------------- \begin{figure}[h] \centerline{\input{wavemechanics-fig/Figures/gammaraymicroscope.pdf}} \caption{$\gamma-$ ray microscope} \label{fig:gammaraymicroscope} \end{figure} ---------------------------------------- My question is: How to specify dimensions of the figure in this case. Please help me.
