如何改变网格的描边不透明度？

Question

我需要在其他图形对象顶部添加透明网格。我知道该选项strokeopacity可用于更改路径的描边不透明度。我进行了如下尝试，但它不适用于网格。

你能告诉我如何实现我的目标吗？

\documentclass{article}
\usepackage{pstricks}

\usepackage[active,tightpage]{preview}
\PreviewEnvironment{pspicture}
\PreviewBorder=12pt


\newpsstyle{mygridstyle}{
    strokeopacity=0.5,
    subgriddiv=4,
    gridlabels=5pt,
    gridlabelcolor=red,
    gridfont=Verdana,
    gridcolor=magenta!50,
    subgridcolor=gray!50,
    gridwidth=2pt,
    subgridwidth=1pt,
}


\begin{document}
\begin{pspicture}(3,3)
\psset{linewidth=10pt,strokeopacity=0.5}
\psline[linecolor=blue](3,3)
\psline[linecolor=red](3,0)(0,3)
\psgrid[style=mygridstyle]
\end{pspicture}
\end{document}

Answer 1

pstricks.tex使用来自的版本http://texnik.dante.de/tex/generic/pstricks/的值strokeopacity被考虑在内。顺便说一句：您可以使用showgrid=top：

\documentclass{article}
\usepackage{pstricks}

\newpsstyle{gridstyle}{
    strokeopacity=0.5,
    subgriddiv=4,
    gridlabels=5pt,
    gridlabelcolor=red,
    gridfont=Verdana,
    gridcolor=magenta!50,
    subgridcolor=gray!50,
    gridwidth=2pt,
    subgridwidth=1pt,
}

\begin{document}
\begin{pspicture}[showgrid=top](3,3)
\psset{linewidth=10pt}%,strokeopacity=0.5}
\psline[linecolor=blue](3,3)
\psline[linecolor=red](3,0)(0,3)
\end{pspicture}
\end{document}

我pstricks.tex今天也会将其上传到 CTAN。
