Hi, Hans and Jin-Hwan:

Here is a simple ConTeXt metafun demo file:

\starttext
\setupcolors[state=start]
\startMPpage
  path p ; color c[] ;
  p := fullsquare scaled 4cm ;
  c[0] := transparent(1,.5,red) ;
  c[1] := transparent(1,.5,green) ;
  c[2] := transparent(1,.5,blue) ;
  for i = 0 upto 2 :
    fill p rotated (i*30) withcolor white ;
  endfor ;
  for i = 0 upto 2 :
    fill p rotated (i*30) withcolor c[i] ;
  endfor ;
  addbackground withcolor transparent(1,.5,cmyk(0,0,1,0)) ;
\stopMPpage
\stoptext

When process the file using luatex or pdftex, we can see a nice picture there.
However, when
1) using pdftex to produce the dvi, and convert the dvi using dvipdfmx
2) using xetex to produce the pdf using xdvipdfmx
the figure is placed at the wrong place. there will be a displacement
for all the metapost figures when xetex is used to produce the
graphics. I attach the wrong result in the mail.

So my question is :
- is this a bug in ConTeXt, or in (x)dvipdfmx. can the bug be fixed?

Thanks

Yue Wang
