Hi,
some months ago the withshading, withfromshadecolor etc. have apparently been
replaced by the more general withshademethod, withshadevector,
withshadecolors, etc. methods.
I have issues converting the old withshading code to the withshademethod
version. The old code had no problems shading to transparent:
\definecolor [trans] [a=multiply, t=.5, s=.5]
\starttext
\startMPcode
path p; p:=fullsquare xyscaled (8cm, 8cm);
fill p
withshading("linear", ulcorner p, llcorner p)
withfromshadecolor \MPcolor{black}
withtoshadecolor \MPcolor{trans};
\stopMPcode
\stoptext
The new code appears to work in general, but only if no shading to
transparent is being used:
\definecolor [trans] [a=multiply, t=.5, s=.5]
\starttext
\startMPcode
% works
fill fullcircle scaled 10cm withcolor \MPcolor{trans};
fill fullsquare xyscaled (15cm, 15cm)
withshademethod "linear"
withshadevector (0,1)
% works
withshadecolors (red,\MPcolor{blue})
% fails
%% withshadecolors (red,\MPcolor{trans})
;
\stopMPcode
\stoptext
How to make transparent shadings work with the new mechanism?
