<DIV>When I used system procedure to convert a pdf file into a gif one in my ncl script, it jumped out a error message about convert said that </DIV>
<DIV>convert:PDFDelegateFailed '[ghostscript library 9.19]'...</DIV>
<DIV>I had searched it in the internet, somebody said it means i didn't install ghostscript before. But I can convert them in my cygwin outside ncl app. </DIV>
<DIV>So what's wrong with my ncl script? How can I recover it?<BR>Thank you for reading my message! Best wishes. </DIV>
