Max (et al),
were you hoping the ConTeXt distribution would ship its own
pgfutil-context.def, or were you hoping that someone could convince Henri
to put the RGB change in?
And, if anyone has the will to push this (or add it in to a ConTeXt
distribution version), I'd still like the cmyk support, even if there is no
ability to specify colour profiles:
\def\pgfutil@emu@cmyk#1#2,#3,#4,#5\@nil
{
\pgfmathsetmacro{\@red@}{(1 - #2) * (1 - #5)}%
\pgfmathsetmacro{\@green@}{(1 - #3) * (1 - #5)}%
\pgfmathsetmacro{\@blue@}{(1 - #4) * (1 - #5)}%
\expandafter\edef\csname\string\color@#1\endcsname
{\noexpand\xcolor@ {}{}{rgb}{\@red@,\@green@,\@blue@}}
}
I don't see that it would hurt anything, even if it doesn't give complete
cmyk support.
Cheers.
Jim
