How I can change the distance dimension like the picture below. In the \dim={add dim, distance} have two parameter I want to add 1 parameter for distance of dimesion like picture 1 , and rolate the text in picture 2. enter image description here

enter image description here

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations,decorations.markings,decorations.text}

\begin{document}
 \pgfkeys{/pgf/decoration/.cd,
      distance/.initial=10pt, 
      distance2/ .initial=10pt
}  

\pgfdeclaredecoration{add dim}{final}{
\state{final}{% 
\pgfmathsetmacro{\dist}{45pt*\pgfkeysvalueof{/pgf/decoration/distance}
            /abs(\pgfkeysvalueof{/pgf/decoration/distance})}    
          \pgfpathmoveto{\pgfpoint{0pt}{0pt}}             
          \pgfpathlineto{\pgfpoint{0pt}{\dist}}   
          \pgfpathmoveto{\pgfpoint{\pgfdecoratedpathlength}{0pt}} 
          \pgfpathlineto{\pgfpoint{(\pgfdecoratedpathlength}{\dist}}     
          \pgfsetarrowsstart{latex}
          \pgfsetarrowsend{latex}
          \pgfpathmoveto{\pgfpoint{0pt}{\dist}}
          \pgfpathlineto{\pgfpoint{\pgfdecoratedpathlength}{\dist}} 
          \pgfusepath{stroke} 
          \pgfpathmoveto{\pgfpoint{0pt}{0pt}}
          \pgfpathlineto{\pgfpoint{\pgfdecoratedpathlength}{0pt}}
}}

\tikzset{dim/.style args={#1,#2,#3}{decoration={add dim,distance=#2},
                decorate,
                postaction={decorate,decoration={text along path,
                                                 raise=#2,
                                                 text align={align=center},
                                                 text={#1}}}}}

\begin{tikzpicture}
\coordinate (A) at (0,0);
\coordinate (B) at (4,2);

\draw[dim={35 cm,34pt,34pt}]  (A) --  (B); 

\draw[fill=gray] (A) circle(2pt); 
\draw[fill=gray] (B) circle(2pt);

\end{tikzpicture}

\end{document}
  • What is the difference between #2 and #3. – Symbol 1 Jul 20 '17 at 12:00
  • And what is distance2 for? – cfr Jul 20 '17 at 18:43
  • distance2 is #3 it's dist in the code. – Le Quan Plus Jul 21 '17 at 7:38
