[NTG-context] LinearShade trouble
Dear ConTeXt list, I have been having troubles with LinearShade with ConTeXt for quite a while, even with the latest version. Steps to reproduce: There is a test.tex at the bottom of this e-mail: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=580447#5 Copy paste it into the ConTeXt Live interface at the ConTeXt Garden. Result is blank. But what I expect (produced with an ancient version of ConTeXt, Debian version 2008.05.21-1): http://people.debian.org/~akumar/dump/test_expected.pdf Could you please let me know where things are going wrong? The mail has the log files attached. Thanks.

Thanks. Here's the code:
file
\setuppapersize[S6][S6]
\setuppagenumbering[state=stop]
\switchtobodyfont[modern,20pt]
\setupcolors[state=start]
\setupbackgrounds[page][background=color,backgroundcolor=darkblue]
\startcolor[white]
\setuptolerance[verytolerant,stretch]
\definecolor[a][r=0,g=0,b=1]
\definecolor[b][r=0,g=0,b=0.05]
\startuniqueMPgraphic{LinearShade}
path p ;
p := unitsquare xscaled \overlaywidth yscaled \overlayheight ;
linear_shade(p,6,\MPcolor{a},\MPcolor{b}) ;
\stopuniqueMPgraphic
\defineoverlay[shaded][\useMPgraphic{LinearShade}]
\setupbackgrounds[page][background={shaded}]
\starttext
Here's my first presentation in \CONTEXT!
Isn't it amazing?
\stoptext
/file
This is from an old ConTeXt example I copied from your documentation
(I don't recall exactly).
Thanks!
Kumar

The mail has the log files attached. You have a problem with metapost not being run. Search the contextgarden for write18 for the solution. BTW: You cannot use the contextgarden to check if you code is working. The same restrictions as on your system apply. Consider using mkiv as Hans suggested.

I added metafun to shell_escape_commands, and that did the trick! Thanks!
