[Dvipng] Does `dvipng' support the '.dvi' file generated by using pgf/tikz

[张贤义]

I want to use `dvipng' to convert the `.dvi' file to `.png', when i stduy to use the 
'pgf/tikz' package to generate graph in tex.

dvipng does not work for it!

OS: windows xp sp2,
tex: miktex 2.7
The the '.tex' code is :
---------------------------------------------------------
\documentclass{article} % say
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (-1.5,0) -- (1.5,0) -- (0,-1.5) -- (0,15);
\end{tikzpicture}.
\end{document}
---------------------------------------------------------

the associated file is packed:
ex6aux
ex6.dvi
ex6.log
ex6.tex
commandline.rec (the output of command line)
