Mysterious clipping for shaded MetaFun page background
Dear folks, can anyone reproduce this? (Live ConTeXt on the garden seems to run into this \faststartcolor thing ... with pdfTeX.) Uncomment the page background overlay and the top bit of the frames' titles will be chipped off ... doesn't happen for the plain vanilla color background on my machine. --- \enableregime[utf] \setupcolors[state=start] \usetypescript[palatino][\defaultencoding] \setupbodyfont[palatino,30pt] \startMPenvironment \usetypescript[palatino][\defaultencoding] \switchtobodyfont[palatino,30pt] \stopMPenvironment \startuseMPgraphic{FunnyFrame} picture pic; path a,b; a := unitsquare xyscaled (OverlayWidth,OverlayHeight); pic := textext(\MPstring{FunnyFrame}); setbounds pic to (boundingbox pic) enlarged (BodyFontSize/5); pic := pic shifted (OverlayWidth/2,OverlayHeight+(ypart ulcorner pic)/2); drawoptions(withpen pencircle scaled OverlayLineWidth withcolor OverlayLineColor); b := a topenlarged (ypart center pic-OverlayHeight); b := b smoothed BodyFontSize; fill b withcolor white; draw b; b := (boundingbox pic) smoothed (BodyFontSize/2); fill b withcolor yellow; draw b; draw pic withcolor black; setbounds currentpicture to a; \stopuseMPgraphic \defineoverlay[FunnyFrame][\useMPgraphic{FunnyFrame}] \defineframedtext [FunnyText] [background=FunnyFrame, frame=off, rulethickness=3pt, width=\textwidth] \def\startFrame#1{% \setMPtext{FunnyFrame}{\hbox spread 1em{\hss\strut#1\hss}}% \startFunnyText} \def\stopFrame{\stopFunnyText} \startuniqueMPgraphic{shade} path p; p := unitsquare xyscaled (OverlayWidth,OverlayHeight); linear_shade(p,6,blue,white); \stopuniqueMPgraphic \defineoverlay[shade][\useMPgraphic{shade}] %\setupbackgrounds % [page] % [background=shade] %\setupbackgrounds % [page] % [background=color, % backgroundcolor=blue] \noheaderandfooterlines \starttext \showframe \startFrame{Test 1} The quick brown fox jumps over the lazy dog. \stopFrame \startFrame{Test 2} The quick brown fox jumps over the lazy dog. \stopFrame \stoptext --- Cheerio, Oliver

the boundingbox sets the final size of the gfx. if your gfx is larger than the bb, things will overlap. just enlarge the bb, so that it fits the gfx. Peter

it may help to increase \def\objectoffset{1cm} (by default reused objects clip and this creates a virtual bbox) ----------------------------------------------------------------- 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 -----------------------------------------------------------------
