\begin{abstract}
The package \LPack{pst-geometrictools} offers some customizable options to setup a \emph{protractor}, a \emph{ruler},
a \emph{compass} and \emph{pencils} to the users' wishes. Some geometric tools are predefined
and ready-to-use for the customer to be able to present some pixel-free graphics showing the handling of some geometric tools.
The geometric tools can be scaled, rotated, positioned, colored as wanted, even labeled---if wanted.
These tools were already available since years within diverse examples---however not yet packaged together in pure PostScript. This was done within this package.
We recommend to use the package \LPack{pst-eucl} (by \textit{Dominique Rodriguez}) which makes it easy to position the tools precisely.
Have fun to use it!

\nxLkeyword{PoCFillCol=}, \nxLkeyword{PoCMineCol=}, \nxLkeyword{RadVS=}, \nxLkeyword{AngleVS=}, \nxLkeyword{RadMul=} and \nxLkeyword{PoCScale=}.

\end{tabularx}
\end{quote}
The command \Lcs{psCompass} offers a positioning
\begin{itemize}
\item either by one point and the radius---a rotation is set with \texttt{[PoCAngle=30]}.
\item or by two points (the radius and initial angle then are calculated automatically)---if one sets an additional rotation with \texttt{[PoCAngle=30]},
these two angles are automatically added. If one will suppress the initial rotation, then set \texttt{[MCAngle=false]}.
Using \texttt{RadVS=<unique name>} and \texttt{AngleVS=<unique name>} you can use the values of the radius respectively the angle within some PostScript calculations.
When you like to use a radius other than the distance between the two points that automatically calculates the radius, use \texttt{RadMul=<decimal number>} to multiply the initial radius with this factor.

\begin{BDef}
\Lcs{psParallels}\OptArgs\Largr{pointA}\Largr{pointB}\Largr{pointC}

\bottomrule
\end{tabularx}
\end{quote}
This command is made to directly draw a line parallel to the line containing \texttt{pointA} and \texttt{pointB}
intersecting at point \texttt{pointC}.
\begin{LTXexample}[pos=t,width=\linewidth]
\psscalebox{0.5}{%
\begin{pspicture}[showgrid=false](-15,-10)(5,3)%
\pnode(-6,1){A}\uput[100](A){A}
\pnode(1,2){B}\uput[100](B){B}
\pnode(2,0){C}\uput[90](C){C}
\pcline[linecolor=BrickRed,nodesepA=-2,nodesepB=-2](A)(B)%
\psParallels[style=Parallelen,RulerScale=0.5,ProScale=1,DistCoeff=1](A)(B)(C)
\pcline[linecolor=BrickRed](GeodrB)(GeodrA)%
\midAB(GeodrB)(GeodrA){M}%
\psPencil[PenLength=5,pencilColA=red,PenScale=0.5]{60}(M)
\end{pspicture}}
\end{LTXexample}
The command \verb+\psParallels[DistCoeff=1](A)(B)(C){angle}+ allows to draw a parallel through the
point C with the help of a ruler and protractor. The angle is the one between the pencil and the vertical.
The command uses the option [DistCoef=] as within pst-eucl. If [DistCoef=0] the hypotenuse of the
protractor lays on the line (AB), the ruler automatically positions below the protractor.
For an animation, we vary [DistCoef=0..1], the protractor moves along the ruler letting the
hypotenuse parallel to the line (AB). If [DistCoef=1], the protractor intersects with the point C.
We can now draw the parallel to (AB) intersecting C.
\newpage
\section{Basic Examples}
\begin{LTXexample}[pos=t,width=16cm]
\psscalebox{0.7}{%
\begin{pspicture}[showgrid=false](-6,-5.5)(10,7)
\psProtractor{0}(0,0)% origin of the protractor
\psRuler{0}(0,0)% origin of the ruler
\psPencil{-30}(6,0)% origin of the pencil
\psCompass{3}(2,0)% origin of the compass
\end{pspicture}}
\end{LTXexample}
We see, that the origins of the \emph{protractor} and \emph{ruler}, \emph{compass} and respectively the \emph{cone end of the pencil} are positioned at $(0|0)$, $(2|0)$, $(6|0)$. Adding an angle rotates the objects around their origins.
For the \emph{protractor} and \emph{ruler}, there are two ways to position them:
\begin{itemize}
\item one point and an angle, like:
\Lcs{psProtractor}\OptArgs\Largb{<angle>}\Largr{<point>}\\
\Lcs{psRuler}\OptArgs\Largb{<angle>}\Largr{<point>}
This is quite self-explanatory. The origin is positioned at the point and the tool is rotated around this point by the chosen angle.
\item two points and an additional angle, like:
\Lcs{psProtractor}\OptArgs\Largb{<additional angle>}\Largr{<pointA>}\Largr{<pointB>}\\
\Lcs{psRuler}\OptArgs\Largb{<additional angle>}\Largr{<pointA>}\Largr{<pointB>}
The origin of the tool is set to pointA. The hypotenuse of the protractor is aligned to the line between pointA and pointB, when the additional angle is chosen to $0$.
\end{itemize}
