Thank you very much for your help.

My question is about the dpi information in emf file. Although vector 
image has noting to do with dpi, I check the property of emf file using 
``mspaint'', which display the figure in 96 dpi with size  384x384 px.

In the help file of ``win.metafile'', the xpinch and ypinch may have 
something to do with the size of emf file. However, when setting it to 
72 by windows.options, only the display size in screen has been changed. 
It don't affect the actual plot size when saving it as emf file. It also 
384x384px instead of 288x288px.

Best,
Jinsong
