PNG format output

[Qingjuan Gu]

Hi, 

When I use 'dottup' and choose 'PNG' output format, there is a error message: Error: Invalid graph value 'png' oth in command line and on web site.

But when I check http://bioinfo.pbi.nrc.ca:8090/EMBOSS/, the png format can work in this site. Does anybody give me some suggestions about this problem.

Thanks a lot.
