[Tex/LaTex] Rotating Mathematical Symbols without losing quality

rotatingsymbols

I need to use the symbol \subsetneq rotated by 45 degrees. I can obtain the required symbol with

\rotatebox[origin=c]{45}{$\subsetneq$}

or equivalently with 

\begin{rotate}{45}
$\subsetneq$
\end{rotate}

but in both cases the quality loss on the symbol is very high.
Does anybody know of a better way to do this?
Thanks

Here is an example:

\documentclass[xcolor=dvipsnames]{beamer}
\usepackage{xcolor, enumerate, MnSymbol, mathtools, graphicx, textpos, rotating}
\begin{document}
\frame{
\begin{rotate}{45}
$\subsetneq$
\end{rotate}
}
\end{document}

Best Answer

The procedure you should follow (taken from http://docs.miktex.org/2.9/manual/advanced.html#psfonts) is

  1. Go to a DOS command prompt

  2. Type initexmf --edit-config-file updmap followed by Return

  3. In the file that opens for editing, add

    Map MnSymbol.map

    at the end

  4. Save the file and exit the file editor

  5. Type initexmf --mkmaps followed by Return at the command prompt

After these steps, pdflatex should use the Type1 font.
