Hi, linear shading in MP does not work with xetex. Consider \setupcolors[state=start] \starttext \startMPcode path p ; p := unitsquare xyscaled (5cm,5cm) ; linear_shade(p,1,red, blue) ; \stopMPcode \stoptext This runs fine with pdftex and luatex, but with xetex I get !

Since no one replied am I correct in assuming that this is currently not possible or requires a lot of work? Aditya
Consider
\setupcolors[state=start]
\starttext
\startMPcode path p ; p := unitsquare xyscaled (5cm,5cm) ;
linear_shade(p,1,red, blue) ; \stopMPcode
\stoptext
This runs fine with pdftex and luatex, but with xetex I get

It is more than simply supp-mpe not being loaded. If I add \input supp-mpe, then I get

My guess is that there are communication problems with the pdf backend (dvipdfmx). In XeTeX, that communication has to happen via \specials. It could be impossible, or it could simply be that Hans doesn't know what \special to output. Best wishes, Taco

it's just that i didn't adapt some spec-dpx code when i went from supp-pdf+supp-mpe to meta-pdf ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
