Graphics, Figures & Tables ⇒ coordinates

[kent]

I wonder how one easily can get from (A) defined by \cordinate (A) at ...
to the specific x and y coordinates of (A). I do not have the angle package available in PGF 3.0 or tkz-2d etc..

Hi Kent,

welcome to the forum!

You could use

test

Code: Select all

\path (A);
\pgfgetlastxy{\xcoord}{\ycoord}

to store the values in these macros.

Thanks for a quick reply indeed!
My PGF 2.0 don't find the command \pgfgetlastxy I am afraid.

[Stefan Kottwitz]

PGF 2.0 is very old, it's very recommendable to update. PGF 2.10 and 3.0 provide new features and libraries. I have no way to test something with the old 2.0.

I appreciate your kind help Stefan.

Can anybody else out there have a solution of my problem using PGF 2.0?
If so, I would be delighted to hear about it.
Regards,
Kent

You could try this way, by defining that macro (I think I read it in post by Andrew Stacey):

Code: Select all

\makeatletter
\newcommand{\getcoords}[3]{%
   \tikz@scan@one@point\pgfutil@firstofone(#1)\relax
  \edef#2{\the\pgf@x}%
  \edef#3{\the\pgf@y}%
}
\makeatother

Then use it in a tikzpicture environment such as:

Code: Select all

\getcoords{A}{\xcoord}{\xcoord}
% just print the x and y values:
\node {\xcoord,\xcoord};

Stefan, it works! Great and thanks. I really appreciate it.
