I would like to draw something like this:
So I would like to highlight the path from 13 -> 9 -> 11 -> 3. How can I draw this path in a Karnough map?
edit: It don't has to be done with kvmacros
, but I would like to have an example with which I can create other Karnaugh maps (with other marks of blocks of ones) without problems.
The Karnaugh map was pretty streight forward, although I would rather like the x at the bottom and w at the right.
\documentclass{article}
\usepackage[pdftex,active,tightpage]{preview}
\setlength\PreviewBorder{2mm}
\usepackage[dvipsnames]{xcolor}
\input{kvmacros}
\begin{document}
\begin{preview}
\karnaughmap{4}{$f(w,x,y,z)$}{{$w$}{$x$}{$y$}{$z$}}%
{
1100
1100
0011
0101
}
{
\textcolor{Blue}{
\put(2,3.5){\oval(3.9,0.9)[]}
}
\textcolor{WildStrawberry}{
\put(0.9,3.5){\oval(1.7,0.8)[]}
}
\textcolor{Green}{
\put(0.7,1.5){\oval(1.9,0.9)}
}
\textcolor{Sepia}{
\put(1.5,1.5){\oval(1.6,0.7)}
}
\textcolor{Red}{
\put(1.92,1){\oval(0.9,1.9)}
}
\textcolor{LimeGreen}{
\put(1.76,-0.2){\oval(0.9,2.1)[t]}
\put(1.76,4.2){\oval(0.9,2.1)[b]}
}
}
\end{preview}
\end{document}

Here is an example of using
tikzmark
:Note:
This does require two runs. First one to determine the locations, and the second to do the drawing.
The
\tikzmark
is from Adding a large brace next to a body of text.Also, I don't know how those coordinates were determined so I just piggy backed onto the existing nodes so added the
tikzmark
to13
and11
and usedshorten >= -4.5ex
to stretch into the node above it.The drawing quality of the
picture
mode\oval
does not seem very good, but perhaps there is someone on this site who can address that issue.Code:
