well... i dont know... i will wait a while...

any LaTeX typed in GeoGebra become an element of a pdf image and i can put 
the siez of the resulting image to something where the LaTeX formulas seem to 
fit to the TeXmacs formulas, but that's not automatic. 
if i have a geogbra image with latex formulas, and if i insert in a TeXmacs 
document the pdf resulting of this GeoGebra, do you know a mean to assign to 
the pdf a size that exactly fits the latex formulas of the GeoGebra to the 
same size than the size of my TeXmacs text and formulas ?

but if i produce a pdf with tikz (the question is the same with GeoGebra), 
since the tikz formula is not IN the texmacs document (there is the pdf 
export between tikz code and TeXmacs), how can i do to have the same size for 
all formulas, the ones of TeXmacs and the ones of the pdf ?

i mean, please have a look to this page : 
http://mathoscope.ouvaton.org/mathoscope_xyz/Prepa/algebre_lineaire/ev_normes.xhtml
there are some curves. These curves are in pdf format. In the pdf there are 
some characters (numbers, formulas...). You can see that the numbers are 
totally not at the same size than the text typed directly in TeXmacs... 
that's exactly my problem.

i have started to read the help documents of TeXmacs. I found this in "lien 
et génération automatique de contenu" (the ensligh must be something like : 
"link and automatic generation of content")

I am sorry it is in french i have copy-pasted it here :

|On a aussi inclus un script de conversion des images contenant des formules
|LaTeX en fichier encapsulé PostScript. Pour inclure une formule LaTeX dans 
une
|image xfig, vous devez saisir la formule en tant que texte, sélectionner une
|police LaTeX et insérer le drapeau spécial dans le texte.

i have no idea what "xfig" means but do you think it could give a direction 
to an answer to my problem ?
