[pstricks] Strikeout macro

[David Arnold]

Doesn't seem to work the way I need it to work:

\documentclass[12pt,a4paper]{article}
\usepackage{amsmath}
\usepackage{pstricks-add}
\usepackage[thicklines]{cancel}
\usepackage{xcolor}
\definecolor{darkred}{rgb}{0.625,0,0}

\newlength{\numwid}
\newlength{\numht}

\newcommand{\strikeout}[1]{%
      \settowidth{\numwid}{#1}
      \settoheight{\numht}{#1}
      \psline[linecolor=darkred](0,0)(\the\numwid,\the\numht)#1}



\renewcommand{\CancelColor}{\red}

\begin{document}

\begin{equation*}
\frac{\psCancel{(x+1)}(x+2)}{\psCancel{(x+1)}}
\end{equation*}

\begin{equation*}
\frac{\cancel{(x+1)}(x+2)}{\cancel{(x+1)}}
\end{equation*}

\begin{equation*}
\frac{\strikeout{(x+1)}(x+2)}{\strikeout{(x+1)}}
\end{equation*}


\end{document}

Please try this:

    \newlength{\numwid}
    \newlength{\numht}

    \newcommand{\strikeout}[1]{%
      \settowidth{\numwid}{#1}
      \settoheight{\numht}{#1}
      \psline[linecolor=Red](0,0)(\the\numwid,\the\numht)#1}


    \strikeout{2}
    \strikeout{$x+1$}
    \strikeout{$x^2-2x+1$}
