placing a tikz/pgf figure

placing a tikz/pgf figure

Hi all,

I'm trying to determine how to best insert a figure/graph created using the tikz/pgf module (I'm using v1.10). The attached sample file compares the result of just using \placefigure and \placefigure with \startcombination[1*1]. In the first case, the result is not centered (which should be default in ConTeXt, if I'm correct) but flushed left. Only if I place the figure inside a \startcombination by using \input, do I get the desired result. If I use \externalfigure inside the \startcombination, I again get an incorrect result. 

In theory, the first version should work but some special settings (using e.g. \useexternalfigure) may be required. I do not know why the second version does work. Does anyone have an idea?

Thanks,

Maarten-Jan

Indeed I also get the results as you describe them. When looking at the 
file *.tmp then you see, that the figure is generated on the fly. When 
external figure is issued, then the textwidth is the base and therefore 
the figure ends up leftaligned. -- In such cases I prefer to have the 
figures prepared in a separate pdf-file by means of
    \startTEXpage -- \stopTEXpage. Afterwards I include the TEXpages 
with \externalfigure referencing the page in the file obtained. -- In my 
experience this makes the runs faster.

Kind regards

Willi

willy, what do i need to install to get this example running?

This is because (I think) that tikzpicture does not return a box.

Replace

    {\externalfigure[tikz.tmp]}

with

    {\hbox{\input \jobname-tikz.tmp\relax}}

I have noticed this \placefigure and I do not know if it is a bug or a 
feature. \placefigure expects you to give a box as a figure. Compare 
the output of

\placefigure
   [here]
   {Left Fulushed}
   {This is a test}

and

\placefigure
   [here]
   {centered}
   {\hbox{This is a test}}


Hans, will adding a \hbox explicitly to \placefigure break anything?

You will need to install tikz from 
(http://sourceforge.net/projects/pgf/). The directory is not TDS 
complaint, so you may need to correct that before installing the tree.

And of course, ignore Till Tantau's comments about ConTeXt on page 
67-68 of the manual. He was working with stone age ConTeXt and still 
manged to get the whole thing working :-)

And whenever you decide to overhaul the input mechanism for metapost, 
tikz has some nice ideas.

I guess that copying these files (at least generic and context) into
texmf tree should be enough:
    ftp://cam.ctan.org/tex-archive/graphics/pgf

Hello,

I've been playing a bit with the most simple tikz examples so far, but
after I saw this example I got an impression that ConTeXt users might
also want to see syntax like

\starttikzpicture[optional options]{name}
 ...
\stoptikzpicture

\usetikzpicture{name}

in addition to the existing one, which would then be equivalent to
syntax of including metapost graphics. There are dozens of other
\start[whatever] commands defined in the module, but I have no idea
what all of them do. Perhaps \startpgfpicture might be another command
worth considering, but I have no idea about the rest.

Maybe commands along the line of metapost (so that everything is 
easier to remeber)

\startreusablePGFgraphic
\startusablePGFgraphic
\startPGFcode
\startstaticPGFfigure ;)

and

\usePGFgraphic, \reusePGFgraphic, etc.

For proper integration, there should also be a mechanism to pass 
\overlayheight and \overlaywidth to the pgfpicture, so that the 
pgfpicture can use it.

I am just curious, does everyone use pgf for standalone graphic or has 
someone also tried to use it with \framed[background=...], which works 
for the most simple cases.

Hi Hasn,

In order to make sure, that the cooperation between tikz and Context 
works okay, you should install pgf 1.10
    http://sourceforge.net/project/showfiles.php?group_id=142562

Further you need to install the Latex package xkeyval.

I hope that will do!
