Hi, I have some trouble using a gradient background (solid) with a transparent element : \startMPinclusions def test_shade (expr a, b) = pickup pencircle scaled 1mm ; color ca ; ca := \MPcolor{a} ; color cb ; cb := \MPcolor{b} ; color cc ; cc := \MPcolor{c} ; sh := define_linear_shade(origin shifted(0cm,.5*\overlayheight),origin,ca,cb) ; fill fullsquare xscaled \overlaywidth yscaled \overlayheight withshade sh; draw origin withcolor cc; draw origin shifted(0cm,-.25*\overlayheight) withcolor cc; enddef ; \stopMPinclusions \setupcolors[state=start] \definecolor[a][r=.57254902,g=.784313725,b=.917647059] \definecolor[b][white] \definecolor[c][darkred] \starttext \defineoverlay[bgoverlay][\uniqueMPgraphic{bg_top_shade}] \setupbackgrounds[page][background=bgoverlay] \startuniqueMPgraphic{bg_top_shade} test_shade(origin, origin shifted(0cm,1cm)); draw fullcircle scaled 10cm shifted (0cm,0.25*\overlayheight) withcolor transparent(1,0.5,white) withpen pencircle scaled 2cm; %%%%%%%% If you comment out the previous line the color rendering is definitelly different... \stopuniqueMPgraphic \input knuth \stoptext I have searched the ML without success, any idea ?
