[XeTeX] centering a picture

[Yves Codet]

Hello.

Here is another of my beginner's questions.

If, using the "float" package, I write this:

\begin{table}[H]
	\begin{center}
		\XeTeXpicfile "indus_pictogramme_figuier.gif" width 6cm
		\caption{Pictogrammes de l’Indus: figuier.}
	\end{center}
\end{table}

the caption is centered but the picture is at the left margin.

But if, imitating an example by Jonathan, I write this:

\begin{table}[H]
	\begin{center}
		\framebox{\setbox0=\hbox{\XeTeXpicfile 
"indus_pictogramme_figuier.gif" width 6cm}\box0}
		\caption{Pictogrammes de l’Indus: figuier.}
	\end{center}
\end{table}

everything is centered. Is this a normal behaviour of LaTeX?

Incidentally, some time ago (about one year actually) members of this 
list helped me to write Sanskrit hyphenation patterns. I have been 
using them since then and they seem to work well: so far I haven't 
noticed any unwanted hyphenation. I wrote to Johannes Braams, asking 
him if he could modify Babel so as to allow the inclusion of these 
patterns thanks to his package, but got no reply. Since they may be 
useful to other people in the TeX community, I would be glad to put 
them at their disposal. To whom should I send them, without them to 
land into a spam box?

Kind regards,

Yves
