TikZ: Get values for predefined dash patterns

Question

Is there a way to get values for predefined dash patterns such as dotted? I would like to use those in another program to create the same visual experience. Or do I have to define my own patterns in order to have the same values?

Answer 1

You can find the definitions of these and many others in the tikz.code.tex file in your distribution (e.g. MikTeX has it under C:\Program Files (x86)\MiKTeX 2.9\tex\generic\pgf\frontendlayer\tikz\ )

\tikzstyle{solid}=                   [dash pattern=]
\tikzstyle{dotted}=                  [dash pattern=on \pgflinewidth off 2pt]
\tikzstyle{densely dotted}=          [dash pattern=on \pgflinewidth off 1pt]
\tikzstyle{loosely dotted}=          [dash pattern=on \pgflinewidth off 4pt]
\tikzstyle{dashed}=                  [dash pattern=on 3pt off 3pt]
\tikzstyle{densely dashed}=          [dash pattern=on 3pt off 2pt]
\tikzstyle{loosely dashed}=          [dash pattern=on 3pt off 6pt]
\tikzstyle{dashdotted}=              [dash pattern=on 3pt off 2pt on \the\pgflinewidth off 2pt]
\tikzstyle{densely dashdotted}=      [dash pattern=on 3pt off 1pt on \the\pgflinewidth off 1pt]
\tikzstyle{loosely dashdotted}=      [dash pattern=on 3pt off 4pt on \the\pgflinewidth off 4pt]
