I know and I used a backgroundcolor and a background simultaneously
in my posted example but what I want is a interface in localframed
without
the overlay solution, the background should also repeated horizontal and
vertical and not streched in both directions.
\defineoverlay[image][\backgroundimage1\overlaywidth\overlayheight{\externalfigure[\framedparameter{backgroundimage}]}]
\framed[width=15cm,height=25cm,backgroundimage=cow.pdf
,background=image]{test}
Hi Hans,
nearly perfect but can I also test if the requested figure did really exist
with
something like
\doiffigure{\framedparameter{backgroundimage}}{\backgroundimage{...}}.
I hope there will be a hidden feature section in the ConTeXtbook with all of
ConTeXt's
little features I don't know at the moment.
\starttext
\def\doiffigureelse#1%
   {\getfiguredimensions[#1]%
    \ifcase\figurewidth
      \expandafter\secondoftwoarguments
    \else
      \expandafter\firstoftwoarguments
    \fi}

\doiffigureelse{cow.pdf}{yes}{no}
\doiffigureelse{xxx.pdf}{no}{yes}

\stoptext
