Thanks David and Duncan,

pdf()/eps() are good options. Can you please tell which function produces
.wmf images.

I finally want to copy/insert these images into word file (.doc) and submit
it to my adviser, and keep a possibility to re-size pictures.

Is it possible to add these .pdf / .eps images into word (instead of latex).

Thanks,
Wenjie
