在 pst-optexp 中本地覆盖 ps-style

Question

默认情况下，使用绘制的图表中的所有光纤pst-optexp都显示为黑色，除非明确设置颜色，如示例所示

\begin{pspicture}(18,6)
    \psset[optexp]{fiber=none, usefiberstyle}
    %\newpsstyle{Fiber}{linecolor=orange, linewidth=2\pslinewidth}
    \newpsstyle{Fiber}{linewidth=2\pslinewidth}
    \pnodes(1.5, 4){LaserIn}(2, 4){LaserOut}
    \pnodes(1.5, 2){SESAMIn}(2, 2){SESAMOut}
    \pnodes(4, 4){InputIsolatorIn}(5, 4){InputIsolatorOut}
    \pnodes(6.5, 2){PolarizerIn}(7.5, 2){PolarizerOut}
    \pnodes(9, 4){TSFIn}(11, 4){TSFOut}
    \pnodes(14, 3){LoopIn}(14, 2){LoopOut}
    \pnodes(10, 1){OutputIsolatorIn}(12,1){OutputIsolatorOut}
    \pnodes(16, 1){LaserOutLow}
    \optdiode[compname=PumpDiode, position=start](LaserIn)(LaserOut){\begin{tabular}{@{}c@{}}Laser\\diode\end{tabular}}
    \optisolator[compname=InputIsolator](InputIsolatorIn)(InputIsolatorOut){Pump Isolator}
    \optfiber[compname=ActiveFiber, position=start, linecolor=red](TSFIn)(TSFOut){Active fiber}
    
    \nput{75}{LaserOutLow}{Laser output}
    
    \drawfiber{InputIsolator}{ActiveFiber}
    \drawfiber{PumpDiode}{InputIsolator}
    \drawfiber{ActiveFiber}(LaserOutLow)
\end{pspicture}

结果是 另一方面，当删除第三行的注释时，我会得到 尽管我明确设置了活动光纤的光纤颜色，但整个光纤仍为橙色。因此，我假设全局设置将始终覆盖光纤颜色的本地设置。这样对吗？或者我仍然可以使用全局光纤颜色并在本地覆盖它吗？

Answer 1

一般来说应该允许你使用本地样式。然而，这方面usefiberstyle=false似乎比较特殊。但你可以使用在本地更改光纤线样式，或者覆盖它：\optfiberaddtoFibernewFiber

\optfiber[compname=ActiveFiber, position=start, addtoFiber={linecolor=red}](TSFIn)(TSFOut){Active fiber}

\documentclass{standalone}
\usepackage{pst-optexp}

    \newpsstyle{Fiber}{linecolor=orange, linewidth=2\pslinewidth}
    \pnodes(1.5, 4){LaserIn}(2, 4){LaserOut}
    \pnodes(1.5, 2){SESAMIn}(2, 2){SESAMOut}
    \pnodes(4, 4){InputIsolatorIn}(5, 4){InputIsolatorOut}
    \pnodes(6.5, 2){PolarizerIn}(7.5, 2){PolarizerOut}
    \pnodes(9, 4){TSFIn}(11, 4){TSFOut}
    \pnodes(14, 3){LoopIn}(14, 2){LoopOut}
    \pnodes(10, 1){OutputIsolatorIn}(12,1){OutputIsolatorOut}
    \pnodes(16, 1){LaserOutLow}
    \optdiode[compname=PumpDiode, position=start](LaserIn)(LaserOut){\begin{tabular}{@{}c@{}}Laser\\diode\end{tabular}}
    \optisolator[compname=InputIsolator](InputIsolatorIn)(InputIsolatorOut){Pump Isolator}

    \nput{75}{LaserOutLow}{Laser output}
    
    \drawfiber{InputIsolator}{ActiveFiber}
    \drawfiber{PumpDiode}{InputIsolator}
    \drawfiber{ActiveFiber}(LaserOutLow)
