Yes, I'm using 'eps' as the first argument of gsn_open_wks!

Ok! I also use 'convert' to directly convert the EPS file to PNG.
But I wanted to know why eps2png gives this error, since the manual says

I used 'png' as argument for gsn_open_wks now, but the result is bad.
The quality of the graphic is poor!
