Interactive things and exact placement of graphics

Interactive things and exact placement of graphics

[Jessica Holle]

Hi,

I have some questions again. :-)
I want to draw a figure with metafun and place this on an exact
place like x=3cm,y=4cm. This figure  will be build of some figures
which I draw with Metafun. In which way I do this? Whith layers? How
should it looks like? Get some small layer with only one figure
together in a big layer?

And when I've build this graphic I want to put text into it and the
whole graphic should be interactive. I want to lay a hyperlink over
this to the web or another page in my document. Is this possible and
in which way?

thx jessica

Hi Jessica,

If you have to superimpose text over the picture(s) then layers are the 
way to go.
For what you want may be you could use the fieldstack-mechanism (see 
metafun manual). - I do not know however how this will work with layers.
To include interactive links in the text there is a command 
\goto[some-reference].
In order to jump to a different document you could use 
\useexternaldocument[reference in this document][name of external 
file][comments], which you can use as follows:
\goto{My external file}[reference in this document::]. More information 
on this subject can be found in the manual mwidget.pdf
A good source for solutions can be the presentation-styles delivered 
with the Context distro, Hans uses often pieces of Metapost within them.

I hope this gives you a clue ...

Willi.

\definelayer[blabla][width=4cm,height=8cm]

\setlayer[blabla][preset=lefttop,x=1cm,y=2cm]{your graphic}

etc etc

grep a bit for layers in the context/base tree
