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 have apparently been replaced by the more general withshademethod, withshadevector, withshadecolors, etc.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?
withtransparency (1,.5)
next beta \definecolor [trans] [a=multiply, t=.5, g=.5] \startMPpage fill fullcircle scaled 12cm withcolor \MPcoloronly{trans}; fill fullcircle scaled 10cm withcolor \MPcolor{trans}; fill fullsquare xyscaled (15cm, 15cm) withshademethod "linear" withshadevector (0,1) withshadecolors (red,\MPcoloronly{trans}) withtransparency \MPtransparency{trans} ; \stopMPpage ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
