Picture commands


\begin{decl}
\vert\qbezier[<N>](<AX>,<AY>)(<BX>,<BY>)(<CX>,<CY>)\vert \\
\vert \bezier{<N>}(<AX>,<AY>)(<BX>,<BY>)(<CX>,<CY>)\vert
\end{decl}
The || command can be used in |picture| mode to draw a quadratic bezier curve from position |(<AX>,<AY>)| to |(<CX>,<CY>)| with control point |(<BX>,<BY>)|. The optional argument N gives the number of points on the curve. For example, the diagram:

\begin{picture}(50,50)
\thicklines
\qbezier(0,0)(0,50)(50,50)
\qbezier[20](0,0)(50,0)(50,50)
\thinlines
\put(0,0){\line(1,1){50}}
\end{picture}
is drawn with:
   \begin{picture}(50,50)
      \thicklines
      \qbezier(0,0)(0,50)(50,50)
      \qbezier[20](0,0)(50,0)(50,50)
      \thinlines
      \put(0,0){\line(1,1){50}}
   \end{picture}
The || command is the same, except that the argument N is not optional. It is provided for compatibility with the LATEX 2.09 |bezier| document style option.
