Help : pdf figure is black !

Help : pdf figure is black !

[Maurice Diamantini]

Bonjour à tous,

I'm trying to switch from Latex + pstrick to latex3 and Metapost 
(alias context :-)

For now, I'm trying to reproduice a Latex + Seminar + pstricks slides.

Before to switch to Metapost, I'd like to include the pstricks figure 
as pdf external file (from eps file)
The figure is OK and I can see it with xpdf or acroreqad.

But when I use it in ConText, the background is all black.
I've been unable to play whith the  various option :

    2
    \externalfigure
        [01-problematique.pst.pdf]
        [width=0.4\textwidth,
         % bfactor=0.9,
         % raster=0.9,
         background=screen,
         % background=color,
         backgroundscreen=1.0,
         backgroundcolor=yellow,
        ]
    3

Any idea ?

P.S.
I think that the "Context" name is a bad choice, because it's
difficult to find on the web (to much pages are found)
It would be better to name it "ConTeX" !

Maurice.

Has 

\externalfigure[01-problematique.pst.pdf][width=0.4\textwidth]

also the black background? Can you upload the figure somewhere?

Are you giving the string "tex" in your search-engine if you
are looking for TeX?

   \setupcolors[state=start]

may help

(in the process of making some presentation, you may want to peek into the 
s-pre-* files)

Yes !
xpdf show the pdf figure well, but not the figure in de pdf
file generated by ConTeXt!
No problem with gv nor with acroread :

Thank you very much!

It does change anything (see the bug from xpdf)

Thank you: so I find the .../cont-tmf/tex/context/base/m-pstric.tex file
and tried the following code.

    \Topic{Test intégrant du pstricks }
    
    % pstric
    % \startPSTRICKS[offset=2pt] ... \stopPSTRICKS
    
    works in both dvi and pdf mode
    \usemodule[pstric]
    
    A--
    \startPSTRICKS
      \pspicture(0,0)(10,10)
        \dorecurse{10}{\psline(0,0)(\recurselevel,10)}
        \dorecurse{10}{\psline(0,0)(10,\recurselevel)}
      \endpspicture
    \stopPSTRICKS
    --B

But for now, it doesn't work 
(but it doesn't mater as I can import pdf file)
