how to get an image format flowchart

["wei jm" <wei@uni-duisburg.de>]

Hello,everybody,
   
     I have a problem while using context to create some flowcharts. The beginning of 
my tex source file looks like:
     
     \setupoutput[pdftex]
     \usemodule[chart]   

     Naturally I got a flowchart in pdf version. But a pdf version flowchart is 
not suitable for inserting into a paper or a report. Then I try to use software to convert it from pdf format into some other imgage formats. But none of them was satisfied. 
I wonder how can I direct get a flowchart in some imgage formats (e.g. in png, jpg format) from the source tex file. Are there some 
tricks in the settings of the tex source file?


   Thanks in advance!

   Best regards
