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

Hi, Yue Wang,
Many years have passed since I wrote spec-dpx.tex for ConTeXt.
The file spec-dpx.tex included in texlive 2008 (the only one I have)
looks quite changed according to the progression of ConTeXt.
Anyway, your example worked when I change the 763th line of
spec-dpx.tex as follows:
{\scratchdimen\wd#2\scratchdimen.5\scratchdimen\hskip-\the\scratchdimen
==>
{%
But, I do not know this modification of \setMPPDFobject does not affect
other cases. Could you check more examples?
Best regards, ChoF.

Hi, all:
I tried this fix with some of my documents and it seems that this
fixed all my documents.
Hans, can you commit that to HEAD?
Thanks a lot, Jin-Hwan:)
